# Contributing
Thank you for your interest! Sanic is always looking for contributors. If you
don't feel comfortable contributing code, adding docstrings to the source files
is very appreciated.
We are committed to providing a friendly, safe and welcoming environment for all,
regardless of gender, sexual orientation, disability, ethnicity, religion,
or similar personal characteristic.
Our [code of conduct](./CONDUCT.md) sets the standards for behavior.
## Installation
To develop on sanic (and mainly to just run the tests) it is highly recommend to
install from sources.
So assume you have already cloned the repo and are in the working directory with
a virtual environment already set up, then run:
```bash
python setup.py develop && pip install -r requirements-dev.txt
```
## Running tests
To run the tests for sanic it is recommended to use tox like so:
```bash
tox
```
See it's that simple!
## Pull requests!
So the pull request approval rules are pretty simple:
1. All pull requests must pass unit tests.
2. All pull requests must be reviewed and approved by at least
one current collaborator on the project.
3. All pull requests must pass flake8 checks.
4. All pull requests must be consistent with the existing code.
5. If you decide to remove/change anything from any common interface
a deprecation message should accompany it.
6. If you implement a new feature you should have at least one unit
test to accompany it.
7. An example must be one of the following:
* Example of how to use Sanic
* Example of how to use Sanic extensions
* Example of how to use Sanic and asynchronous library
## Documentation
Sanic's documentation is built
using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in
Markdown and can be found in the `docs` folder, while the module reference is
automatically generated using `sphinx-apidoc`.
To generate the documentation from scratch:
```bash
sphinx-apidoc -fo docs/_api/ sanic
sphinx-build -b html docs docs/_build
```
The HTML documentation will be created in the `docs/_build` folder.
## Warning
One of the main goals of Sanic is speed. Code that lowers the performance of
Sanic without significant gains in usability, security, or features may not be
merged. Please don't let this intimidate you! If you have any concerns about an
idea, open an issue for discussion and help.

Thank you for your interest! Sanic is always looking for contributors. If you
don't feel comfortable contributing code, adding docstrings to the source files,
or helping with the `Sanic User Guide <https://github.com/sanic-org/sanic-guide>`_
by providing documentation or implementation examples would be appreciated!
We are committed to providing a friendly, safe and welcoming environment for all,
regardless of gender, sexual orientation, disability, ethnicity, religion,
or similar personal characteristic.
Our `code of conduct <https://github.com/sanic-org/sanic/blob/master/CONDUCT.md>`_ sets the standards for behavior.
Installation
------------
To develop on Sanic (and mainly to just run the tests) it is highly recommend to
install from sources.
So assume you have already cloned the repo and are in the working directory with
a virtual environment already set up, then run:
.. code-block:: bash
pip3 install -e . ".[dev]"
Dependency Changes
------------------
``Sanic`` doesn't use ``requirements*.txt`` files to manage any kind of dependencies related to it in order to simplify the
effort required in managing the dependencies. Please make sure you have read and understood the following section of
the document that explains the way ``sanic`` manages dependencies inside the ``setup.py`` file.
.. list-table::
:header-rows: 1
* - Dependency Type
- Usage
- Installation
* - requirements
- Bare minimum dependencies required for sanic to function
- ``pip3 install -e .``
* - tests_require / extras_require['test']
- Dependencies required to run the Unit Tests for ``sanic``
- ``pip3 install -e '.[test]'``
* - extras_require['dev']
- Additional Development requirements to add contributing
- ``pip3 install -e '.[dev]'``
* - extras_require['docs']
- Dependencies required to enable building and enhancing sanic documentation
- ``pip3 install -e '.[docs]'``
Running all tests
-----------------
To run the tests for Sanic it is recommended to use tox like so:
.. code-block:: bash
tox
See it's that simple!
``tox.ini`` contains different environments. Running ``tox`` without any arguments will
run all unittests, perform lint and other checks.
Run unittests
-------------
``tox`` environment -> ``[testenv]``
To execute only unittests, run ``tox`` with environment like so:
.. code-block:: bash
tox -e py36 -v -- tests/test_config.py
# or
tox -e py37 -v -- tests/test_config.py
Run lint checks
---------------
``tox`` environment -> ``[testenv:lint]``
Permform ``flake8``\ , ``black`` and ``isort`` checks.
.. code-block:: bash
tox -e lint
Run type annotation checks
---------------
``tox`` environment -> ``[testenv:type-checking]``
Permform ``mypy`` checks.
.. code-block:: bash
tox -e type-checking
Run other checks
----------------
``tox`` environment -> ``[testenv:check]``
Perform other checks.
.. code-block:: bash
tox -e check
Run Static Analysis
-------------------
``tox`` environment -> ``[testenv:security]``
Perform static analysis security scan
.. code-block:: bash
tox -e security
Run Documentation sanity check
------------------------------
``tox`` environment -> ``[testenv:docs]``
Perform sanity check on documentation
.. code-block:: bash
tox -e docs
Code Style
----------
To maintain the code consistency, Sanic uses following tools.
#. `isort <https://github.com/timothycrosley/isort>`_
#. `black <https://github.com/python/black>`_
#. `flake8 <https://github.com/PyCQA/flake8>`_
isort
*****
``isort`` sorts Python imports. It divides imports into three
categories sorted each in alphabetical order.
#. built-in
#. third-party
#. project-specific
black
*****
``black`` is a Python code formatter.
flake8
******
``flake8`` is a Python style guide that wraps following tools into one.
#. PyFlakes
#. pycodestyle
#. Ned Batchelder's McCabe script
``isort``\ , ``black`` and ``flake8`` checks are performed during ``tox`` lint checks.
The **easiest** way to make your code conform is to run the following before committing.
.. code-block:: bash
make pretty
Refer `tox <https://tox.readthedocs.io/en/latest/index.html>`_ documentation for more details.
Pull requests
-------------
So the pull request approval rules are pretty simple:
#. All pull requests must pass unit tests.
#. All pull requests must be reviewed and approved by at least one current member of the Core Developer team.
#. All pull requests must pass flake8 checks.
#. All pull requests must match ``isort`` and ``black`` requirements.
#. All pull requests must be **PROPERLY** type annotated, unless exemption is given.
#. All pull requests must be consistent with the existing code.
#. If you decide to remove/change anything from any common interface a deprecation message should accompany it in accordance with our `deprecation policy <https://sanicframework.org/en/guide/project/policies.html#deprecation>`_.
#. If you implement a new feature you should have at least one unit test to accompany it.
#. An example must be one of the following:
* Example of how to use Sanic
* Example of how to use Sanic extensions
* Example of how to use Sanic and asynchronous library
Documentation
-------------
Sanic's API documentation is built using `sphinx <http://www.sphinx-doc.org/en/1.5.1/>`_ with module references
automatically generated using ``sphinx-apidoc``.
The User Guide is in the `sanic-guide <https://github.com/sanic-org/sanic-guide>`_ repository.
To generate the documentation from scratch:
.. code-block:: bash
sphinx-apidoc -fo docs/_api/ sanic
sphinx-build -b html docs docs/_build
# There is a simple make command provided to ease the work required in generating
# the documentation
make docs
The HTML documentation will be created in the ``docs/_build`` folder.
You can run the following to have a live development server with the API documents
.. code-block:: bash
make docs-serve
Refer to the User Guide repo for documentation on how to contribute there.
.. warning::
One of the main goals of Sanic is speed. Code that lowers the performance of
Sanic without significant gains in usability, security, or features may not be

Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
.. list-table::
:widths: 15 85
:stub-columns: 1
On top of being Flask-like, Sanic supports async request handlers. This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.

Sanic is a **Python 3.7+** web server and web framework that's written to go fast. It allows the usage of the ``async/await`` syntax added in Python 3.5, which makes your code non-blocking and speedy.
Sanic is also ASGI compliant, so you can deploy it with an `alternative ASGI webserver <https://sanic.readthedocs.io/en/latest/sanic/deploying.html#running-via-asgi>`_.
`Source code on GitHub <https://github.com/sanic-org/sanic/>`_ | `Help and discussion board <https://community.sanicframework.org/>`_ | `User Guide <https://sanicframework.org>`_ | `Chat on Discord <https://discord.gg/FARQzAEMAA>`_
The project is maintained by the community, for the community. **Contributions are welcome!**
The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.

Installation
------------
``pip3 install sanic``
Sanic makes use of ``uvloop`` and ``ujson`` to help with performance. If you do not want to use those packages, simply add an environmental variable ``SANIC_NO_UVLOOP=true`` or ``SANIC_NO_UJSON=true`` at install time.
.. code:: shell
$ export SANIC_NO_UVLOOP=true
$ export SANIC_NO_UJSON=true
$ pip3 install --no-binary :all: sanic
.. note::
If you are running on a clean install of Fedora 28 or above, please make sure you have the ``redhat-rpm-config`` package installed in case if you want to
use ``sanic`` with ``ujson`` dependency.
.. note::
Windows support is currently "experimental" and on a best-effort basis. Multiple workers are also not currently supported on Windows (see `Issue #1517 <https://github.com/sanic-org/sanic/issues/1517>`_), but setting ``workers=1`` should launch the server successfully.
If you have a project that utilizes Sanic make sure to comment on the `issue <https://github.com/huge-success/sanic/issues/396>`_ that we use to track those projects!
Hello World Example
-------------------
@@ -118,55 +19,85 @@ Hello World Example
from sanic import Sanic
from sanic.response import json
app = Sanic("My Hello, world app")

@app.route('/')
async def test(request):
return json({'hello': 'world'})
if __name__ == '__main__':
app.run()
app.run(host='0.0.0.0', port=8000)
Sanic can now be easily run using ``sanic hello.app``.
Installation
------------

[2018-12-30 11:37:41 +0200] [13564] [INFO] Starting worker [13564]
To install sanic without uvloop or ujson using bash, you can provide either or both of these environmental variables
using any truthy string like `'y', 'yes', 't', 'true', 'on', '1'` and setting the NO_X to true will stop that features
installation.
And, we can verify it is working: ``curl localhost:8000 -i``
- ``SANIC_NO_UVLOOP=true SANIC_NO_UJSON=true pip install sanic``
.. code::

# Blueprints
Blueprints are objects that can be used for sub-routing within an application.
Instead of adding routes to the application instance, blueprints define similar
methods for adding routes, which are then registered with the application in a
flexible and pluggable manner.
Blueprints are especially useful for larger applications, where your
application logic can be broken down into several groups or areas of
responsibility.
## My First Blueprint
The following shows a very simple blueprint that registers a handler-function at
the root `/` of your application.
Suppose you save this file as `my_blueprint.py`, which can be imported into your
main application later.
```python
from sanic.response import json
from sanic import Blueprint
bp = Blueprint('my_blueprint')
@bp.route('/')
async def bp_root(request):
return json({'my': 'blueprint'})
```
## Registering blueprints
Blueprints must be registered with the application.
```python
from sanic import Sanic
from my_blueprint import bp
app = Sanic(__name__)
app.blueprint(bp)
app.run(host='0.0.0.0', port=8000, debug=True)
```
This will add the blueprint to the application and register any routes defined
by that blueprint. In this example, the registered routes in the `app.router`
will look like:
```python
[Route(handler=<function bp_root at 0x7f908382f9d8>, methods=frozenset({'GET'}), pattern=re.compile('^/$'), parameters=[], name='my_blueprint.bp_root', uri='/')]
```
## Blueprint groups and nesting
Blueprints may also be registered as part of a list or tuple, where the registrar will recursively cycle through any sub-sequences of blueprints and register them accordingly. The `Blueprint.group` method is provided to simplify this process, allowing a 'mock' backend directory structure mimicking what's seen from the front end. Consider this (quite contrived) example:
```
api/
├──content/
│ ├──authors.py
│ ├──static.py
│ └──__init__.py
├──info.py
└──__init__.py
app.py
```
Initialization of this app's blueprint hierarchy could go as follows:
```python
# api/content/authors.py
from sanic import Blueprint
authors = Blueprint('content_authors', url_prefix='/authors')
```
```python
# api/content/static.py
from sanic import Blueprint
static = Blueprint('content_static', url_prefix='/static')
```
```python
# api/content/__init__.py
from sanic import Blueprint
from .static import static
from .authors import authors
content = Blueprint.group(static, authors, url_prefix='/content')
```
```python
# api/info.py
from sanic import Blueprint
info = Blueprint('info', url_prefix='/info')
```
```python
# api/__init__.py
from sanic import Blueprint
from .content import content
from .info import info
api = Blueprint.group(content, info, url_prefix='/api')
```
And registering these blueprints in `app.py` can now be done like so:
```python
# app.py
from sanic import Sanic
from .api import api
app = Sanic(__name__)
app.blueprint(api)
```
## Using blueprints
Blueprints have much the same functionality as an application instance.
### WebSocket routes
WebSocket handlers can be registered on a blueprint using the `@bp.websocket`
decorator or `bp.add_websocket_route` method.
### Middleware
Using blueprints allows you to also register middleware globally.
```python
@bp.middleware
async def print_on_request(request):
print("I am a spy")
@bp.middleware('request')
async def halt_request(request):
return text('I halted the request')
@bp.middleware('response')
async def halt_response(request, response):
return text('I halted the response')
```
### Exceptions
Exceptions can be applied exclusively to blueprints globally.
```python
@bp.exception(NotFound)
def ignore_404s(request, exception):
return text("Yep, I totally found the page: {}".format(request.url))
```
### Static files
Static files can be served globally, under the blueprint prefix.
```python
# suppose bp.name == 'bp'
bp.static('/web/path', '/folder/to/serve')
# also you can pass name parameter to it for url_for
bp.static('/web/path', '/folder/to/server', name='uploads')
app.url_for('static', name='bp.uploads', filename='file.txt') == '/bp/web/path/file.txt'
```
## Start and stop
Blueprints can run functions during the start and stop process of the server.
If running in multiprocessor mode (more than 1 worker), these are triggered
after the workers fork.
Available events are:
- `before_server_start`: Executed before the server begins to accept connections
- `after_server_start`: Executed after the server begins to accept connections
- `before_server_stop`: Executed before the server stops accepting connections
- `after_server_stop`: Executed after the server is stopped and all requests are complete
```python
bp = Blueprint('my_blueprint')
@bp.listener('before_server_start')
async def setup_connection(app, loop):
global database
database = mysql.connect(host='127.0.0.1'...)
@bp.listener('after_server_stop')
async def close_connection(app, loop):
await database.close()
```
## Use-case: API versioning
Blueprints can be very useful for API versioning, where one blueprint may point
at `/v1/<routes>`, and another pointing at `/v2/<routes>`.
When a blueprint is initialised, it can take an optional `url_prefix` argument,
which will be prepended to all routes defined on the blueprint. This feature
can be used to implement our API versioning scheme.
```python
# blueprints.py
from sanic.response import text
from sanic import Blueprint
blueprint_v1 = Blueprint('v1', url_prefix='/v1')
blueprint_v2 = Blueprint('v2', url_prefix='/v2')
@blueprint_v1.route('/')
async def api_v1_root(request):
return text('Welcome to version 1 of our documentation')
@blueprint_v2.route('/')
async def api_v2_root(request):
return text('Welcome to version 2 of our documentation')
```
When we register our blueprints on the app, the routes `/v1` and `/v2` will now
point to the individual blueprints, which allows the creation of *sub-sites*
for each API version.
```python
# main.py
from sanic import Sanic
from blueprints import blueprint_v1, blueprint_v2
app = Sanic(__name__)
app.blueprint(blueprint_v1, url_prefix='/v1')
app.blueprint(blueprint_v2, url_prefix='/v2')
app.run(host='0.0.0.0', port=8000, debug=True)
```
## URL Building with `url_for`
If you wish to generate a URL for a route inside of a blueprint, remember that the endpoint name
takes the format `<blueprint_name>.<handler_name>`. For example:
```python
@blueprint_v1.route('/')
async def root(request):
url = request.app.url_for('v1.post_handler', post_id=5) # --> '/v1/post/5'
return redirect(url)
@blueprint_v1.route('/post/<post_id>')
async def post_handler(request, post_id):
return text('Post {} in Blueprint V1'.format(post_id))
```

# Class-Based Views
Class-based views are simply classes which implement response behaviour to
requests. They provide a way to compartmentalise handling of different HTTP
request types at the same endpoint. Rather than defining and decorating three
different handler functions, one for each of an endpoint's supported request
type, the endpoint can be assigned a class-based view.
## Defining views
A class-based view should subclass `HTTPMethodView`. You can then implement
class methods for every HTTP request type you want to support. If a request is
received that has no defined method, a `405: Method not allowed` response will
be generated.
To register a class-based view on an endpoint, the `app.add_route` method is
used. The first argument should be the defined class with the method `as_view`
invoked, and the second should be the URL endpoint.
The available methods are `get`, `post`, `put`, `patch`, and `delete`. A class
using all these methods would look like the following.
```python
from sanic import Sanic
from sanic.views import HTTPMethodView
from sanic.response import text
app = Sanic('some_name')
class SimpleView(HTTPMethodView):
def get(self, request):
return text('I am get method')
def post(self, request):
return text('I am post method')
def put(self, request):
return text('I am put method')
def patch(self, request):
return text('I am patch method')
def delete(self, request):
return text('I am delete method')
app.add_route(SimpleView.as_view(), '/')
```
You can also use `async` syntax.
```python
from sanic import Sanic
from sanic.views import HTTPMethodView
from sanic.response import text
app = Sanic('some_name')
class SimpleAsyncView(HTTPMethodView):
async def get(self, request):
return text('I am async get method')
app.add_route(SimpleAsyncView.as_view(), '/')
```
## URL parameters
If you need any URL parameters, as discussed in the routing guide, include them
in the method definition.
```python
class NameView(HTTPMethodView):
def get(self, request, name):
return text('Hello {}'.format(name))
app.add_route(NameView.as_view(), '/<name>')
```
## Decorators
If you want to add any decorators to the class, you can set the `decorators`
class variable. These will be applied to the class when `as_view` is called.
```python
class ViewWithDecorator(HTTPMethodView):
decorators = [some_decorator_here]
def get(self, request, name):
return text('Hello I have a decorator')
def post(self, request, name):
return text("Hello I also have a decorator")
app.add_route(ViewWithDecorator.as_view(), '/url')
```
But if you just want to decorate some functions and not all functions, you can do as follows:
```python
class ViewWithSomeDecorator(HTTPMethodView):
@staticmethod
@some_decorator_here
def get(request, name):
return text("Hello I have a decorator")
def post(self, request, name):
return text("Hello I don't have any decorators")
```
## URL Building
If you wish to build a URL for an HTTPMethodView, remember that the class name will be the endpoint
that you will pass into `url_for`. For example:
```python
@app.route('/')
def index(request):
url = app.url_for('SpecialClassView')
return redirect(url)
class SpecialClassView(HTTPMethodView):
def get(self, request):
return text('Hello from the Special Class View!')
app.add_route(SpecialClassView.as_view(), '/special_class_view')
```
## Using CompositionView
As an alternative to the `HTTPMethodView`, you can use `CompositionView` to
move handler functions outside of the view class.
Handler functions for each supported HTTP method are defined elsewhere in the
source, and then added to the view using the `CompositionView.add` method. The
first parameter is a list of HTTP methods to handle (e.g. `['GET', 'POST']`),
and the second is the handler function. The following example shows
`CompositionView` usage with both an external handler function and an inline
lambda:
```python
from sanic import Sanic
from sanic.views import CompositionView
from sanic.response import text
app = Sanic(__name__)
def get_handler(request):
return text('I am a get method')
view = CompositionView()
view.add(['GET'], get_handler)
view.add(['POST', 'PUT'], lambda request: text('I am a post/put method'))
# Use the new view to handle requests to the base URL
app.add_route(view, '/')
```
Note: currently you cannot build a URL for a CompositionView using `url_for`.

# Configuration
Any reasonably complex application will need configuration that is not baked into the actual code. Settings might be different for different environments or installations.
## Basics
Sanic holds the configuration in the `config` attribute of the application object. The configuration object is merely an object that can be modified either using dot-notation or like a dictionary:
```
app = Sanic('myapp')
app.config.DB_NAME = 'appdb'
app.config.DB_USER = 'appuser'
```
Since the config object actually is a dictionary, you can use its `update` method in order to set several values at once:
```
db_settings = {
'DB_HOST': 'localhost',
'DB_NAME': 'appdb',
'DB_USER': 'appuser'
}
app.config.update(db_settings)
```
In general the convention is to only have UPPERCASE configuration parameters. The methods described below for loading configuration only look for such uppercase parameters.
## Loading Configuration
There are several ways how to load configuration.
### From Environment Variables
Any variables defined with the `SANIC_` prefix will be applied to the sanic config. For example, setting `SANIC_REQUEST_TIMEOUT` will be loaded by the application automatically and fed into the `REQUEST_TIMEOUT` config variable. You can pass a different prefix to Sanic:
```python
app = Sanic(load_env='MYAPP_')
```
Then the above variable would be `MYAPP_REQUEST_TIMEOUT`. If you want to disable loading from environment variables you can set it to `False` instead:
```python
app = Sanic(load_env=False)
```
### From an Object
If there are a lot of configuration values and they have sensible defaults it might be helpful to put them into a module:
```
import myapp.default_settings
app = Sanic('myapp')
app.config.from_object(myapp.default_settings)
```
You could use a class or any other object as well.
### From a File
Usually you will want to load configuration from a file that is not part of the distributed application. You can load configuration from a file using `from_pyfile(/path/to/config_file)`. However, that requires the program to know the path to the config file. So instead you can specify the location of the config file in an environment variable and tell Sanic to use that to find the config file:
```
app = Sanic('myapp')
app.config.from_envvar('MYAPP_SETTINGS')
```
Then you can run your application with the `MYAPP_SETTINGS` environment variable set:
```
$ MYAPP_SETTINGS=/path/to/config_file python3 myapp.py
INFO: Goin' Fast @ http://0.0.0.0:8000
```
The config files are regular Python files which are executed in order to load them. This allows you to use arbitrary logic for constructing the right configuration. Only uppercase variables are added to the configuration. Most commonly the configuration consists of simple key value pairs:
```
# config_file
DB_HOST = 'localhost'
DB_NAME = 'appdb'
DB_USER = 'appuser'
```
## Builtin Configuration Values
Out of the box there are just a few predefined values which can be overwritten when creating the application.
| Variable | Default | Description |
| ------------------------- | --------- | ------------------------------------------------------ |
| REQUEST_MAX_SIZE | 100000000 | How big a request may be (bytes) |
| REQUEST_TIMEOUT | 60 | How long a request can take to arrive (sec) |
| RESPONSE_TIMEOUT | 60 | How long a response can take to process (sec) |
| KEEP_ALIVE | True | Disables keep-alive when False |
| KEEP_ALIVE_TIMEOUT | 5 | How long to hold a TCP connection open (sec) |
| GRACEFUL_SHUTDOWN_TIMEOUT | 15.0 | How long take to force close non-idle connection (sec) |
| ACCESS_LOG | True | Disable or enable access log |
### The different Timeout variables:
A request timeout measures the duration of time between the instant when a new open TCP connection is passed to the Sanic backend server, and the instant when the whole HTTP request is received. If the time taken exceeds the `REQUEST_TIMEOUT` value (in seconds), this is considered a Client Error so Sanic generates a HTTP 408 response and sends that to the client. Adjust this value higher if your clients routinely pass very large request payloads or upload requests very slowly.
A response timeout measures the duration of time between the instant the Sanic server passes the HTTP request to the Sanic App, and the instant a HTTP response is sent to the client. If the time taken exceeds the `RESPONSE_TIMEOUT` value (in seconds), this is considered a Server Error so Sanic generates a HTTP 503 response and sets that to the client. Adjust this value higher if your application is likely to have long-running process that delay the generation of a response.
### What is Keep Alive? And what does the Keep Alive Timeout value do?
Keep-Alive is a HTTP feature indroduced in HTTP 1.1. When sending a HTTP request, the client (usually a web browser application) can set a Keep-Alive header to indicate for the http server (Sanic) to not close the TCP connection after it has send the response. This allows the client to reuse the existing TCP connection to send subsequent HTTP requests, and ensures more efficient network traffic for both the client and the server.
The `KEEP_ALIVE` config variable is set to `True` in Sanic by default. If you don't need this feature in your application, set it to `False` to cause all client connections to close immediately after a response is sent, regardless of the Keep-Alive header on the request.
The amount of time the server holds the TCP connection open is decided by the server itself. In Sanic, that value is configured using the `KEEP_ALIVE_TIMEOUT` value. By default, it is set to 5 seconds, this is the same default setting as the Apache HTTP server and is a good balance between allowing enough time for the client to send a new request, and not holding open too many connections at once. Do not exceed 75 seconds unless you know your clients are using a browser which supports TCP connections held open for that long.
For reference:
```
Apache httpd server default keepalive timeout = 5 seconds
Nginx server default keepalive timeout = 75 seconds
Nginx performance tuning guidelines uses keepalive = 15 seconds
IE (5-9) client hard keepalive limit = 60 seconds
Firefox client hard keepalive limit = 115 seconds
Opera 11 client hard keepalive limit = 120 seconds
Chrome 13+ client keepalive limit > 300+ seconds
```

# Contributing
Thank you for your interest! Sanic is always looking for contributors. If you
don't feel comfortable contributing code, adding docstrings to the source files
is very appreciated.
## Installation
To develop on sanic (and mainly to just run the tests) it is highly recommend to
install from sources.
So assume you have already cloned the repo and are in the working directory with
a virtual environment already set up, then run:
```bash
python setup.py develop && pip install -r requirements-dev.txt
```
## Running tests
To run the tests for sanic it is recommended to use tox like so:
```bash
tox
```
See it's that simple!
## Pull requests!
So the pull request approval rules are pretty simple:
* All pull requests must pass unit tests
* All pull requests must be reviewed and approved by at least
one current collaborator on the project
* All pull requests must pass flake8 checks
* If you decide to remove/change anything from any common interface
a deprecation message should accompany it.
* If you implement a new feature you should have at least one unit
test to accompany it.
## Documentation
Sanic's documentation is built
using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in
Markdown and can be found in the `docs` folder, while the module reference is
automatically generated using `sphinx-apidoc`.
To generate the documentation from scratch:
```bash
sphinx-apidoc -fo docs/_api/ sanic
sphinx-build -b html docs docs/_build
```
The HTML documentation will be created in the `docs/_build` folder.
## Warning
One of the main goals of Sanic is speed. Code that lowers the performance of
Sanic without significant gains in usability, security, or features may not be
merged. Please don't let this intimidate you! If you have any concerns about an
idea, open an issue for discussion and help.

Cookies
=======
Cookies are pieces of data which persist inside a user's browser. Sanic can
both read and write cookies, which are stored as key-value pairs.
.. warning::
Cookies can be freely altered by the client. Therefore you cannot just store
data such as login information in cookies as-is, as they can be freely altered
by the client. To ensure data you store in cookies is not forged or tampered
with by the client, use something like `itsdangerous`_ to cryptographically
sign the data.
Reading cookies
---------------
A user's cookies can be accessed via the ``Request`` object's ``cookies`` dictionary.
.. code-block:: python
from sanic.response import text
@app.route("/cookie")
async def test(request):
test_cookie = request.cookies.get('test')
return text("Test cookie set to: {}".format(test_cookie))
Writing cookies
---------------
When returning a response, cookies can be set on the ``Response`` object.
.. code-block:: python
from sanic.response import text
@app.route("/cookie")
async def test(request):
response = text("There's a cookie up in this response")
response.cookies['test'] = 'It worked!'
response.cookies['test']['domain'] = '.gotta-go-fast.com'
response.cookies['test']['httponly'] = True
return response
Deleting cookies
----------------
Cookies can be removed semantically or explicitly.
.. code-block:: python
from sanic.response import text
@app.route("/cookie")
async def test(request):
response = text("Time to eat some cookies muahaha")
# This cookie will be set to expire in 0 seconds
del response.cookies['kill_me']
# This cookie will self destruct in 5 seconds
response.cookies['short_life'] = 'Glad to be here'
response.cookies['short_life']['max-age'] = 5
del response.cookies['favorite_color']
# This cookie will remain unchanged
response.cookies['favorite_color'] = 'blue'
response.cookies['favorite_color'] = 'pink'
del response.cookies['favorite_color']
return response
Response cookies can be set like dictionary values and have the following
parameters available:
- ``expires`` (datetime): The time for the cookie to expire on the client's browser.
- ``path`` (string): The subset of URLs to which this cookie applies. Defaults to /.
- ``comment`` (string): A comment (metadata).
- ``domain`` (string): Specifies the domain for which the cookie is valid. An
explicitly specified domain must always start with a dot.
- ``max-age`` (number): Number of seconds the cookie should live for.
- ``secure`` (boolean): Specifies whether the cookie will only be sent via HTTPS.
- ``httponly`` (boolean): Specifies whether the cookie cannot be read by Javascript.

# Custom Protocols
*Note: this is advanced usage, and most readers will not need such functionality.*
You can change the behavior of Sanic's protocol by specifying a custom
protocol, which should be a subclass
of
[asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
This protocol can then be passed as the keyword argument `protocol` to the `sanic.run` method.
The constructor of the custom protocol class receives the following keyword
arguments from Sanic.
- `loop`: an `asyncio`-compatible event loop.
- `connections`: a `set` to store protocol objects. When Sanic receives
`SIGINT` or `SIGTERM`, it executes `protocol.close_if_idle` for all protocol
objects stored in this set.
- `signal`: a `sanic.server.Signal` object with the `stopped` attribute. When
Sanic receives `SIGINT` or `SIGTERM`, `signal.stopped` is assigned `True`.
- `request_handler`: a coroutine that takes a `sanic.request.Request` object
and a `response` callback as arguments.
- `error_handler`: a `sanic.exceptions.Handler` which is called when exceptions
are raised.
- `request_timeout`: the number of seconds before a request times out.
- `request_max_size`: an integer specifying the maximum size of a request, in bytes.
## Example
An error occurs in the default protocol if a handler function does not return
an `HTTPResponse` object.
By overriding the `write_response` protocol method, if a handler returns a
string it will be converted to an `HTTPResponse object`.
```python
from sanic import Sanic
from sanic.server import HttpProtocol
from sanic.response import text
app = Sanic(__name__)
class CustomHttpProtocol(HttpProtocol):
def __init__(self, *, loop, request_handler, error_handler,
signal, connections, request_timeout, request_max_size):
super().__init__(
loop=loop, request_handler=request_handler,
error_handler=error_handler, signal=signal,
connections=connections, request_timeout=request_timeout,
request_max_size=request_max_size)
def write_response(self, response):
if isinstance(response, str):
response = text(response)
self.transport.write(
response.output(self.request.version)
)
self.transport.close()
@app.route('/')
async def string(request):
return 'string'
@app.route('/1')
async def response(request):
return text('response')
app.run(host='0.0.0.0', port=8000, protocol=CustomHttpProtocol)

Debug Mode
=============
When enabling Sanic's debug mode, Sanic will provide a more verbose logging output
and by default will enable the Auto Reload feature.
.. warning::
Sanic's debug more will slow down the server's performance
and is therefore advised to enable it only in development environments.
Setting the debug mode
----------------------
By setting the ``debug`` mode a more verbose output from Sanic will be outputed
and the Automatic Reloader will be activated.

# Handler Decorators
Since Sanic handlers are simple Python functions, you can apply decorators to them in a similar manner to Flask. A typical use case is when you want some code to run before a handler's code is executed.
## Authorization Decorator
Let's say you want to check that a user is authorized to access a particular endpoint. You can create a decorator that wraps a handler function, checks a request if the client is authorized to access a resource, and sends the appropriate response.
```python
from functools import wraps
from sanic.response import json
def authorized():
def decorator(f):
@wraps(f)
async def decorated_function(request, *args, **kwargs):
# run some method that checks the request
# for the client's authorization status
is_authorized = check_request_for_authorization_status(request)
if is_authorized:
# the user is authorized.
# run the handler method and return the response
response = await f(request, *args, **kwargs)
return response
else:
# the user is not authorized.
return json({'status': 'not_authorized'}, 403)
return decorated_function
return decorator
@app.route("/")
@authorized()
async def test(request):
return json({'status': 'authorized'})
```

# Deploying
Deploying Sanic is made simple by the inbuilt webserver. After defining an
instance of `sanic.Sanic`, we can call the `run` method with the following
keyword arguments:
- `host` *(default `"127.0.0.1"`)*: Address to host the server on.
- `port` *(default `8000`)*: Port to host the server on.
- `debug` *(default `False`)*: Enables debug output (slows server).
- `ssl` *(default `None`)*: `SSLContext` for SSL encryption of worker(s).
- `sock` *(default `None`)*: Socket for the server to accept connections from.
- `workers` *(default `1`)*: Number of worker processes to spawn.
- `loop` *(default `None`)*: An `asyncio`-compatible event loop. If none is
specified, Sanic creates its own event loop.
- `protocol` *(default `HttpProtocol`)*: Subclass
of
[asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
## Workers
By default, Sanic listens in the main process using only one CPU core. To crank
up the juice, just specify the number of workers in the `run` arguments.
```python
app.run(host='0.0.0.0', port=1337, workers=4)
```
Sanic will automatically spin up multiple processes and route traffic between
them. We recommend as many workers as you have available cores.
## Running via command
If you like using command line arguments, you can launch a Sanic server by
executing the module. For example, if you initialized Sanic as `app` in a file
named `server.py`, you could run the server like so:
`python -m sanic server.app --host=0.0.0.0 --port=1337 --workers=4`
With this way of running sanic, it is not necessary to invoke `app.run` in your
Python file. If you do, make sure you wrap it so that it only executes when
directly run by the interpreter.
```python
if __name__ == '__main__':
app.run(host='0.0.0.0', port=1337, workers=4)
```
## Running via Gunicorn
[Gunicorn](http://gunicorn.org/) Green Unicorn is a WSGI HTTP Server for UNIX.
Its a pre-fork worker model ported from Rubys Unicorn project.
In order to run Sanic application with Gunicorn, you need to use the special `sanic.worker.GunicornWorker`
for Gunicorn `worker-class` argument:
```
gunicorn myapp:app --bind 0.0.0.0:1337 --worker-class sanic.worker.GunicornWorker
```
If your application suffers from memory leaks, you can configure Gunicorn to gracefully restart a worker
after it has processed a given number of requests. This can be a convenient way to help limit the effects
of the memory leak.
See the [Gunicorn Docs](http://docs.gunicorn.org/en/latest/settings.html#max-requests) for more information.
## Asynchronous support
This is suitable if you *need* to share the sanic process with other applications, in particular the `loop`.
However be advised that this method does not support using multiple processes, and is not the preferred way
to run the app in general.
Here is an incomplete example (please see `run_async.py` in examples for something more practical):
```python
server = app.create_server(host="0.0.0.0", port=8000)
loop = asyncio.get_event_loop()
task = asyncio.ensure_future(server)
loop.run_forever()
```

# Exceptions
Exceptions can be thrown from within request handlers and will automatically be
handled by Sanic. Exceptions take a message as their first argument, and can
also take a status code to be passed back in the HTTP response.
## Throwing an exception
To throw an exception, simply `raise` the relevant exception from the
`sanic.exceptions` module.
```python
from sanic.exceptions import ServerError
@app.route('/killme')
async def i_am_ready_to_die(request):
raise ServerError("Something bad happened", status_code=500)
```
You can also use the `abort` function with the appropriate status code:
```python
from sanic.exceptions import abort
from sanic.response import text
@app.route('/youshallnotpass')
async def no_no(request):
abort(401)
# this won't happen
text("OK")
```
## Handling exceptions
To override Sanic's default handling of an exception, the `@app.exception`
decorator is used. The decorator expects a list of exceptions to handle as
arguments. You can pass `SanicException` to catch them all! The decorated
exception handler function must take a `Request` and `Exception` object as
arguments.
```python
from sanic.response import text
from sanic.exceptions import NotFound
@app.exception(NotFound)
async def ignore_404s(request, exception):
return text("Yep, I totally found the page: {}".format(request.url))
```
You can also add an exception handler as such:
```python
from sanic import Sanic
async def server_error_handler(request, exception):
return text("Oops, server error", status=500)
app = Sanic()
app.error_handler.add(Exception, server_error_handler)
```
In some cases, you might want want to add some more error handling
functionality to what is provided by default. In that case, you
can subclass Sanic's default error handler as such:
```python
from sanic import Sanic
from sanic.handlers import ErrorHandler
class CustomErrorHandler(ErrorHandler):
def default(self, request, exception):
''' handles errors that have no error handlers assigned '''
# You custom error handling logic...
return super().default(request, exception)
app = Sanic()
app.error_handler = CustomErrorHandler()
```
## Useful exceptions
Some of the most useful exceptions are presented below:
- `NotFound`: called when a suitable route for the request isn't found.
- `ServerError`: called when something goes wrong inside the server. This
usually occurs if there is an exception raised in user code.
See the `sanic.exceptions` module for the full list of exceptions to throw.

# Getting Started
Make sure you have both [pip](https://pip.pypa.io/en/stable/installing/) and at
least version 3.5 of Python before starting. Sanic uses the new `async`/`await`
syntax, so earlier versions of python won't work.
## 1. Install Sanic
```
python3 -m pip install sanic
```
## 2. Create a file called `main.py`
```python
from sanic import Sanic
from sanic.response import json
app = Sanic()
@app.route("/")
async def test(request):
return json({"hello": "world"})
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8000)
```
## 3. Run the server
```
python3 main.py
```
## 4. Check your browser
Open the address `http://0.0.0.0:8000` in your web browser. You should see
the message *Hello world!*.
You now have a working Sanic server!

Sanic
=================================
Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
On top of being Flask-like, Sanic supports async request handlers. This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!
Sanic aspires to be simple

# Logging
Sanic allows you to do different types of logging (access log, error log) on the requests based on the [python3 logging API](https://docs.python.org/3/howto/logging.html). You should have some basic knowledge on python3 logging if you want to create a new configuration.
### Quick Start
A simple example using default settings would be like this:
```python
from sanic import Sanic
from sanic.log import logger
from sanic.response import text
app = Sanic('test')
@app.route('/')
async def test(request):
logger.info('Here is your log')
return text('Hello World!')
if __name__ == "__main__":
app.run(debug=True, access_log=True)
```
After the server is running, you can see some messages looks like:
```
[2018-11-06 21:16:53 +0800] [24622] [INFO] Goin' Fast @ http://127.0.0.1:8000
[2018-11-06 21:16:53 +0800] [24667] [INFO] Starting worker [24667]
```
You can send a request to server and it will print the log messages:
```
[2018-11-06 21:18:53 +0800] [25685] [INFO] Here is your log
[2018-11-06 21:18:53 +0800] - (sanic.access)[INFO][127.0.0.1:57038]: GET http://localhost:8000/ 200 12
```
To use your own logging config, simply use `logging.config.dictConfig`, or
pass `log_config` when you initialize `Sanic` app:
```python
app = Sanic('test', log_config=LOGGING_CONFIG)
```
And to close logging, simply assign access_log=False:
```python
if __name__ == "__main__":
app.run(access_log=False)
```
This would skip calling logging functions when handling requests.
And you could even do further in production to gain extra speed:
```python
if __name__ == "__main__":
# disable debug messages
app.run(debug=False, access_log=False)
```
### Configuration
By default, log_config parameter is set to use sanic.log.LOGGING_CONFIG_DEFAULTS dictionary for configuration.
There are three `loggers` used in sanic, and **must be defined if you want to create your own logging configuration**:
- sanic.root:<br>
Used to log internal messages.
- sanic.error:<br>
Used to log error logs.
- sanic.access:<br>
Used to log access logs.
#### Log format:
In addition to default parameters provided by python (asctime, levelname, message),
Sanic provides additional parameters for access logger with:
- host (str)<br>
request.ip
- request (str)<br>
request.method + " " + request.url
- status (int)<br>
response.status
- byte (int)<br>
len(response.body)
The default access log format is
```python
%(asctime)s - (%(name)s)[%(levelname)s][%(host)s]: %(request)s %(message)s %(status)d %(byte)d
```

# Middleware And Listeners
Middleware are functions which are executed before or after requests to the
server. They can be used to modify the *request to* or *response from*
user-defined handler functions.
Additionally, Sanic provides listeners which allow you to run code at various points of your application's lifecycle.
## Middleware
There are two types of middleware: request and response. Both are declared
using the `@app.middleware` decorator, with the decorator's parameter being a
string representing its type: `'request'` or `'response'`.
* Request middleware receives only the `request` as argument.
* Response middleware receives both the `request` and `response`.
The simplest middleware doesn't modify the request or response at all:
```
@app.middleware('request')
async def print_on_request(request):
print("I print when a request is received by the server")
@app.middleware('response')
async def print_on_response(request, response):
print("I print when a response is returned by the server")
```
## Modifying the request or response
Middleware can modify the request or response parameter it is given, *as long
as it does not return it*. The following example shows a practical use-case for
this.
```
app = Sanic(__name__)
@app.middleware('response')
async def custom_banner(request, response):
response.headers["Server"] = "Fake-Server"
@app.middleware('response')
async def prevent_xss(request, response):
response.headers["x-xss-protection"] = "1; mode=block"
app.run(host="0.0.0.0", port=8000)
```
The above code will apply the two middleware in order. First, the middleware
**custom_banner** will change the HTTP response header *Server* to
*Fake-Server*, and the second middleware **prevent_xss** will add the HTTP
header for preventing Cross-Site-Scripting (XSS) attacks. These two functions
are invoked *after* a user function returns a response.
## Responding early
If middleware returns a `HTTPResponse` object, the request will stop processing
and the response will be returned. If this occurs to a request before the
relevant user route handler is reached, the handler will never be called.
Returning a response will also prevent any further middleware from running.
```
@app.middleware('request')
async def halt_request(request):
return text('I halted the request')
@app.middleware('response')
async def halt_response(request, response):
return text('I halted the response')
```
## Listeners
If you want to execute startup/teardown code as your server starts or closes, you can use the following listeners:
- `before_server_start`
- `after_server_start`
- `before_server_stop`
- `after_server_stop`
These listeners are implemented as decorators on functions which accept the app object as well as the asyncio loop.
For example:
```
@app.listener('before_server_start')
async def setup_db(app, loop):
app.db = await db_setup()
@app.listener('after_server_start')
async def notify_server_started(app, loop):
print('Server successfully started!')
@app.listener('before_server_stop')
async def notify_server_stopping(app, loop):
print('Server shutting down!')
@app.listener('after_server_stop')
async def close_db(app, loop):
await app.db.close()
```
It's also possible to register a listener using the `register_listener` method.
This may be useful if you define your listeners in another module besides
the one you instantiate your app in.
```
app = Sanic()
async def setup_db(app, loop):
app.db = await db_setup()
app.register_listener(setup_db, 'before_server_start')
```
If you want to schedule a background task to run after the loop has started,
Sanic provides the `add_task` method to easily do so.
```
async def notify_server_started_after_five_seconds():
await asyncio.sleep(5)
print('Server successfully started!')
app.add_task(notify_server_started_after_five_seconds())
```
Sanic will attempt to automatically inject the app, passing it as an argument to the task:
```
async def notify_server_started_after_five_seconds(app):
await asyncio.sleep(5)
print(app.name)
app.add_task(notify_server_started_after_five_seconds)
```
Or you can pass the app explicitly for the same effect:
```
async def notify_server_started_after_five_seconds(app):
await asyncio.sleep(5)
print(app.name)
app.add_task(notify_server_started_after_five_seconds(app))

# Request Data
When an endpoint receives a HTTP request, the route function is passed a
`Request` object.
The following variables are accessible as properties on `Request` objects:
- `json` (any) - JSON body
```python
from sanic.response import json
@app.route("/json")
def post_json(request):
return json({ "received": True, "message": request.json })
```
- `args` (dict) - Query string variables. A query string is the section of a
URL that resembles `?key1=value1&key2=value2`. If that URL were to be parsed,
the `args` dictionary would look like `{'key1': ['value1'], 'key2': ['value2']}`.
The request's `query_string` variable holds the unparsed string value.
```python
from sanic.response import json
@app.route("/query_string")
def query_string(request):
return json({ "parsed": True, "args": request.args, "url": request.url, "query_string": request.query_string })
```
- `raw_args` (dict) - On many cases you would need to access the url arguments in
a less packed dictionary. For same previous URL `?key1=value1&key2=value2`, the
`raw_args` dictionary would look like `{'key1': 'value1', 'key2': 'value2'}`.
- `files` (dictionary of `File` objects) - List of files that have a name, body, and type
```python
from sanic.response import json
@app.route("/files")
def post_json(request):
test_file = request.files.get('test')
file_parameters = {
'body': test_file.body,
'name': test_file.name,
'type': test_file.type,
}
return json({ "received": True, "file_names": request.files.keys(), "test_file_parameters": file_parameters })
```
- `form` (dict) - Posted form variables.
```python
from sanic.response import json
@app.route("/form")
def post_json(request):
return json({ "received": True, "form_data": request.form, "test": request.form.get('test') })
```
- `body` (bytes) - Posted raw body. This property allows retrieval of the
request's raw data, regardless of content type.
```python
from sanic.response import text
@app.route("/users", methods=["POST",])
def create_user(request):
return text("You are trying to create a user with the following POST: %s" % request.body)
```
- `headers` (dict) - A case-insensitive dictionary that contains the request headers.
- `method` (str) - HTTP method of the request (ie `GET`, `POST`).
- `ip` (str) - IP address of the requester.
- `port` (str) - Port address of the requester.
- `socket` (tuple) - (IP, port) of the requester.
- `app` - a reference to the Sanic application object that is handling this request. This is useful when inside blueprints or other handlers in modules that do not have access to the global `app` object.
```python
from sanic.response import json
from sanic import Blueprint
bp = Blueprint('my_blueprint')
@bp.route('/')
async def bp_root(request):
if request.app.config['DEBUG']:
return json({'status': 'debug'})
else:
return json({'status': 'production'})
```
- `url`: The full URL of the request, ie: `http://localhost:8000/posts/1/?foo=bar`
- `scheme`: The URL scheme associated with the request: `http` or `https`
- `host`: The host associated with the request: `localhost:8080`
- `path`: The path of the request: `/posts/1/`
- `query_string`: The query string of the request: `foo=bar` or a blank string `''`
- `uri_template`: Template for matching route handler: `/posts/<id>/`
- `token`: The value of Authorization header: `Basic YWRtaW46YWRtaW4=`
## Accessing values using `get` and `getlist`
The request properties which return a dictionary actually return a subclass of
`dict` called `RequestParameters`. The key difference when using this object is
the distinction between the `get` and `getlist` methods.
- `get(key, default=None)` operates as normal, except that when the value of
the given key is a list, *only the first item is returned*.
- `getlist(key, default=None)` operates as normal, *returning the entire list*.
```python
from sanic.request import RequestParameters
args = RequestParameters()
args['titles'] = ['Post 1', 'Post 2']
args.get('titles') # => 'Post 1'
args.getlist('titles') # => ['Post 1', 'Post 2']
```

# Response
Use functions in `sanic.response` module to create responses.
## Plain Text
```python
from sanic import response
@app.route('/text')
def handle_request(request):
return response.text('Hello world!')
```
## HTML
```python
from sanic import response
@app.route('/html')
def handle_request(request):
return response.html('<p>Hello world!</p>')
```
## JSON
```python
from sanic import response
@app.route('/json')
def handle_request(request):
return response.json({'message': 'Hello world!'})
```
## File
```python
from sanic import response
@app.route('/file')
async def handle_request(request):
return await response.file('/srv/www/whatever.png')
```
## Streaming
```python
from sanic import response
@app.route("/streaming")
async def index(request):
async def streaming_fn(response):
response.write('foo')
response.write('bar')
return response.stream(streaming_fn, content_type='text/plain')
```
## File Streaming
For large files, a combination of File and Streaming above
```python
from sanic import response
@app.route('/big_file.png')
async def handle_request(request):
return await response.file_stream('/srv/www/whatever.png')
```
## Redirect
```python
from sanic import response
@app.route('/redirect')
def handle_request(request):
return response.redirect('/json')
```
## Raw
Response without encoding the body
```python
from sanic import response
@app.route('/raw')
def handle_request(request):
return response.raw(b'raw data')
```
## Modify headers or status
To modify headers or status code, pass the `headers` or `status` argument to those functions:
```python
from sanic import response
@app.route('/json')
def handle_request(request):
return response.json(
{'message': 'Hello world!'},
headers={'X-Served-By': 'sanic'},
status=200
)

# Routing
Routing allows the user to specify handler functions for different URL endpoints.
A basic route looks like the following, where `app` is an instance of the
`Sanic` class:
```python
from sanic.response import json
@app.route("/")
async def test(request):
return json({ "hello": "world" })
```
When the url `http://server.url/` is accessed (the base url of the server), the
final `/` is matched by the router to the handler function, `test`, which then
returns a JSON object.
Sanic handler functions must be defined using the `async def` syntax, as they
are asynchronous functions.
## Request parameters
Sanic comes with a basic router that supports request parameters.
To specify a parameter, surround it with angle quotes like so: `<PARAM>`.
Request parameters will be passed to the route handler functions as keyword
arguments.
```python
from sanic.response import text
@app.route('/tag/<tag>')
async def tag_handler(request, tag):
return text('Tag - {}'.format(tag))
```
To specify a type for the parameter, add a `:type` after the parameter name,
inside the quotes. If the parameter does not match the specified type, Sanic
will throw a `NotFound` exception, resulting in a `404: Page not found` error
on the URL.
```python
from sanic.response import text
@app.route('/number/<integer_arg:int>')
async def integer_handler(request, integer_arg):
return text('Integer - {}'.format(integer_arg))
@app.route('/number/<number_arg:number>')
async def number_handler(request, number_arg):
return text('Number - {}'.format(number_arg))
@app.route('/person/<name:[A-z]+>')
async def person_handler(request, name):
return text('Person - {}'.format(name))
@app.route('/folder/<folder_id:[A-z0-9]{0,4}>')
async def folder_handler(request, folder_id):
return text('Folder - {}'.format(folder_id))
```
## HTTP request types
By default, a route defined on a URL will be available for only GET requests to that URL.
However, the `@app.route` decorator accepts an optional parameter, `methods`,
which allows the handler function to work with any of the HTTP methods in the list.
```python
from sanic.response import text
@app.route('/post', methods=['POST'])
async def post_handler(request):
return text('POST request - {}'.format(request.json))
@app.route('/get', methods=['GET'])
async def get_handler(request):
return text('GET request - {}'.format(request.args))
```
There is also an optional `host` argument (which can be a list or a string). This restricts a route to the host or hosts provided. If there is a also a route with no host, it will be the default.
```python
@app.route('/get', methods=['GET'], host='example.com')
async def get_handler(request):
return text('GET request - {}'.format(request.args))
# if the host header doesn't match example.com, this route will be used
@app.route('/get', methods=['GET'])
async def get_handler(request):
return text('GET request in default - {}'.format(request.args))
```
There are also shorthand method decorators:
```python
from sanic.response import text
@app.post('/post')
async def post_handler(request):
return text('POST request - {}'.format(request.json))
@app.get('/get')
async def get_handler(request):
return text('GET request - {}'.format(request.args))
```
## The `add_route` method
As we have seen, routes are often specified using the `@app.route` decorator.
However, this decorator is really just a wrapper for the `app.add_route`
method, which is used as follows:
```python
from sanic.response import text
# Define the handler functions
async def handler1(request):
return text('OK')
async def handler2(request, name):
return text('Folder - {}'.format(name))
async def person_handler2(request, name):
return text('Person - {}'.format(name))
# Add each handler function as a route
app.add_route(handler1, '/test')
app.add_route(handler2, '/folder/<name>')
app.add_route(person_handler2, '/person/<name:[A-z]>', methods=['GET'])
```
## URL building with `url_for`
Sanic provides a `url_for` method, to generate URLs based on the handler method name. This is useful if you want to avoid hardcoding url paths into your app; instead, you can just reference the handler name. For example:
```python
from sanic.response import redirect
@app.route('/')
async def index(request):
# generate a URL for the endpoint `post_handler`
url = app.url_for('post_handler', post_id=5)
# the URL is `/posts/5`, redirect to it
return redirect(url)
@app.route('/posts/<post_id>')
async def post_handler(request, post_id):
return text('Post - {}'.format(post_id))
```
Other things to keep in mind when using `url_for`:
- Keyword arguments passed to `url_for` that are not request parameters will be included in the URL's query string. For example:
```python
url = app.url_for('post_handler', post_id=5, arg_one='one', arg_two='two')
# /posts/5?arg_one=one&arg_two=two
```
- Multivalue argument can be passed to `url_for`. For example:
```python
url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'])
# /posts/5?arg_one=one&arg_one=two
```
- Also some special arguments (`_anchor`, `_external`, `_scheme`, `_method`, `_server`) passed to `url_for` will have special url building (`_method` is not support now and will be ignored). For example:
```python
url = app.url_for('post_handler', post_id=5, arg_one='one', _anchor='anchor')
# /posts/5?arg_one=one#anchor
url = app.url_for('post_handler', post_id=5, arg_one='one', _external=True)
# //server/posts/5?arg_one=one
# _external requires passed argument _server or SERVER_NAME in app.config or url will be same as no _external
url = app.url_for('post_handler', post_id=5, arg_one='one', _scheme='http', _external=True)
# http://server/posts/5?arg_one=one
# when specifying _scheme, _external must be True
# you can pass all special arguments one time
url = app.url_for('post_handler', post_id=5, arg_one=['one', 'two'], arg_two=2, _anchor='anchor', _scheme='http', _external=True, _server='another_server:8888')
# http://another_server:8888/posts/5?arg_one=one&arg_one=two&arg_two=2#anchor
```
- All valid parameters must be passed to `url_for` to build a URL. If a parameter is not supplied, or if a parameter does not match the specified type, a `URLBuildError` will be thrown.
## WebSocket routes
Routes for the WebSocket protocol can be defined with the `@app.websocket`
decorator:
```python
@app.websocket('/feed')
async def feed(request, ws):
while True:
data = 'hello!'
print('Sending: ' + data)
await ws.send(data)
data = await ws.recv()
print('Received: ' + data)
```
Alternatively, the `app.add_websocket_route` method can be used instead of the
decorator:
```python
async def feed(request, ws):
pass
app.add_websocket_route(my_websocket_handler, '/feed')
```
Handlers for a WebSocket route are passed the request as first argument, and a
WebSocket protocol object as second argument. The protocol object has `send`
and `recv` methods to send and receive data respectively.
WebSocket support requires the [websockets](https://github.com/aaugustin/websockets)
package by Aymeric Augustin.
## About `strict_slashes`
You can make `routes` strict to trailing slash or not, it's configurable.
```python
# provide default strict_slashes value for all routes
app = Sanic('test_route_strict_slash', strict_slashes=True)
# you can also overwrite strict_slashes value for specific route
@app.get('/get', strict_slashes=False)
def handler(request):
return text('OK')
# It also works for blueprints
bp = Blueprint('test_bp_strict_slash', strict_slashes=True)
@bp.get('/bp/get', strict_slashes=False)
def handler(request):
return text('OK')
app.blueprint(bp)
```
## User defined route name
You can pass `name` to change the route name to avoid using the default name (`handler.__name__`).
```python
app = Sanic('test_named_route')
@app.get('/get', name='get_handler')
def handler(request):
return text('OK')
# then you need use `app.url_for('get_handler')`
# instead of # `app.url_for('handler')`
# It also works for blueprints
bp = Blueprint('test_named_bp')
@bp.get('/bp/get', name='get_handler')
def handler(request):
return text('OK')
app.blueprint(bp)
# then you need use `app.url_for('test_named_bp.get_handler')`
# instead of `app.url_for('test_named_bp.handler')`
# different names can be used for same url with different methods
@app.get('/test', name='route_test')
def handler(request):
return text('OK')
@app.post('/test', name='route_post')
def handler2(request):
return text('OK POST')
@app.put('/test', name='route_put')
def handler3(request):
return text('OK PUT')
# below url are the same, you can use any of them
# '/test'
app.url_for('route_test')
# app.url_for('route_post')
# app.url_for('route_put')
# for same handler name with different methods
# you need specify the name (it's url_for issue)
@app.get('/get')
def handler(request):
return text('OK')
@app.post('/post', name='post_handler')
def handler(request):
return text('OK')
# then
# app.url_for('handler') == '/get'
# app.url_for('post_handler') == '/post'
```
## Build URL for static files
You can use `url_for` for static file url building now.
If it's for file directly, `filename` can be ignored.
```python
app = Sanic('test_static')
app.static('/static', './static')
app.static('/uploads', './uploads', name='uploads')
app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
bp = Blueprint('bp', url_prefix='bp')
bp.static('/static', './static')
bp.static('/uploads', './uploads', name='uploads')
bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
app.blueprint(bp)
# then build the url
app.url_for('static', filename='file.txt') == '/static/file.txt'
app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
app.url_for('static', name='uploads', filename='file.txt') == '/uploads/file.txt'
app.url_for('static', name='best_png') == '/the_best.png'
# blueprint url building
app.url_for('static', name='bp.static', filename='file.txt') == '/bp/static/file.txt'
app.url_for('static', name='bp.uploads', filename='file.txt') == '/bp/uploads/file.txt'
app.url_for('static', name='bp.best_png') == '/bp/static/the_best.png'
```

# Static Files
Static files and directories, such as an image file, are served by Sanic when
registered with the `app.static()` method. The method takes an endpoint URL and a
filename. The file specified will then be accessible via the given endpoint.
```python
from sanic import Sanic
from sanic.blueprints import Blueprint
app = Sanic(__name__)
# Serves files from the static folder to the URL /static
app.static('/static', './static')
# use url_for to build the url, name defaults to 'static' and can be ignored
app.url_for('static', filename='file.txt') == '/static/file.txt'
app.url_for('static', name='static', filename='file.txt') == '/static/file.txt'
# Serves the file /home/ubuntu/test.png when the URL /the_best.png
# is requested
app.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
# you can use url_for to build the static file url
# you can ignore name and filename parameters if you don't define it
app.url_for('static', name='best_png') == '/the_best.png'
app.url_for('static', name='best_png', filename='any') == '/the_best.png'
# you need define the name for other static files
app.static('/another.png', '/home/ubuntu/another.png', name='another')
app.url_for('static', name='another') == '/another.png'
app.url_for('static', name='another', filename='any') == '/another.png'
# also, you can use static for blueprint
bp = Blueprint('bp', url_prefix='/bp')
bp.static('/static', './static')
# servers the file directly
bp.static('/the_best.png', '/home/ubuntu/test.png', name='best_png')
app.blueprint(bp)
app.url_for('static', name='bp.static', filename='file.txt') == '/bp/static/file.txt'
app.url_for('static', name='bp.best_png') == '/bp/test_best.png'
app.run(host="0.0.0.0", port=8000)
```
> **Note:** Sanic does not provide directory index when you serve a static directory.
## Virtual Host
The `app.static()` method also support **virtual host**. You can serve your static files with spefic **virtual host** with `host` argument. For example:
```python
from sanic import Sanic
app = Sanic(__name__)
app.static('/static', './static')
app.static('/example_static', './example_static', host='www.example.com')
```
## Streaming Large File
In some cases, you might server large file(ex: videos, images, etc.) with Sanic. You can choose to use **streaming file** rather than download directly.
Here is an example:
```python
from sanic import Sanic
app = Sanic(__name__)
app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=True)
```
When `stream_large_files` is `True`, Sanic will use `file_stream()` instead of `file()` to serve static files. This will use **1KB** as the default chunk size. And, if needed, you can also use a custom chunk size. For example:
```python
from sanic import Sanic
app = Sanic(__name__)
chunk_size = 1024 * 1024 * 8 # Set chunk size to 8KB
app.static('/large_video.mp4', '/home/ubuntu/large_video.mp4', stream_large_files=chunk_size)
```

# Streaming
## Request Streaming
Sanic allows you to get request data by stream, as below. When the request ends, `request.stream.get()` returns `None`. Only post, put and patch decorator have stream argument.
```python
from sanic import Sanic
from sanic.views import CompositionView
from sanic.views import HTTPMethodView
from sanic.views import stream as stream_decorator
from sanic.blueprints import Blueprint
from sanic.response import stream, text
bp = Blueprint('blueprint_request_stream')
app = Sanic('request_stream')
class SimpleView(HTTPMethodView):
@stream_decorator
async def post(self, request):
result = ''
while True:
body = await request.stream.get()
if body is None:
break
result += body.decode('utf-8')
return text(result)
@app.post('/stream', stream=True)
async def handler(request):
async def streaming(response):
while True:
body = await request.stream.get()
if body is None:
break
body = body.decode('utf-8').replace('1', 'A')
await response.write(body)
return stream(streaming)
@bp.put('/bp_stream', stream=True)
async def bp_handler(request):
result = ''
while True:
body = await request.stream.get()
if body is None:
break
result += body.decode('utf-8').replace('1', 'A')
return text(result)
async def post_handler(request):
result = ''
while True:
body = await request.stream.get()
if body is None:
break
result += body.decode('utf-8')
return text(result)
app.blueprint(bp)
app.add_route(SimpleView.as_view(), '/method_view')
view = CompositionView()
view.add(['POST'], post_handler, stream=True)
app.add_route(view, '/composition_view')
if __name__ == '__main__':
app.run(host='127.0.0.1', port=8000)
```
## Response Streaming
Sanic allows you to stream content to the client with the `stream` method. This method accepts a coroutine callback which is passed a `StreamingHTTPResponse` object that is written to. A simple example is like follows:
```python
from sanic import Sanic
from sanic.response import stream
app = Sanic(__name__)
@app.route("/")
async def test(request):
async def sample_streaming_fn(response):
await response.write('foo,')
await response.write('bar')
return stream(sample_streaming_fn, content_type='text/csv')
```
This is useful in situations where you want to stream content to the client that originates in an external service, like a database. For example, you can stream database records to the client with the asynchronous cursor that `asyncpg` provides:
```python
@app.route("/")
async def index(request):
async def stream_from_db(response):
conn = await asyncpg.connect(database='test')
async with conn.transaction():
async for record in conn.cursor('SELECT generate_series(0, 10)'):
await response.write(record[0])
return stream(stream_from_db)
```

# Testing
Sanic endpoints can be tested locally using the `test_client` object, which
depends on the additional [aiohttp](https://aiohttp.readthedocs.io/en/stable/)
library.
The `test_client` exposes `get`, `post`, `put`, `delete`, `patch`, `head` and `options` methods
for you to run against your application. A simple example (using pytest) is like follows:
```python
# Import the Sanic app, usually created with Sanic(__name__)
from external_server import app
def test_index_returns_200():
request, response = app.test_client.get('/')
assert response.status == 200
def test_index_put_not_allowed():
request, response = app.test_client.put('/')
assert response.status == 405
```
Internally, each time you call one of the `test_client` methods, the Sanic app is run at `127.0.0.1:42101` and
your test request is executed against your application, using `aiohttp`.
The `test_client` methods accept the following arguments and keyword arguments:
- `uri` *(default `'/'`)* A string representing the URI to test.
- `gather_request` *(default `True`)* A boolean which determines whether the
original request will be returned by the function. If set to `True`, the
return value is a tuple of `(request, response)`, if `False` only the
response is returned.
- `server_kwargs` *(default `{}`) a dict of additional arguments to pass into `app.run` before the test request is run.
- `debug` *(default `False`)* A boolean which determines whether to run the server in debug mode.
The function further takes the `*request_args` and `**request_kwargs`, which are passed directly to the aiohttp ClientSession request.
For example, to supply data to a GET request, you would do the following:
```python
def test_get_request_includes_data():
params = {'key1': 'value1', 'key2': 'value2'}
request, response = app.test_client.get('/', params=params)
assert request.args.get('key1') == 'value1'
```
And to supply data to a JSON POST request:
```python
def test_post_json_request_includes_data():
data = {'key1': 'value1', 'key2': 'value2'}
request, response = app.test_client.post('/', data=json.dumps(data))
assert request.json.get('key1') == 'value1'
```
More information about
the available arguments to aiohttp can be found
[in the documentation for ClientSession](https://aiohttp.readthedocs.io/en/stable/client_reference.html#client-session).
## pytest-sanic
[pytest-sanic](https://github.com/yunstanford/pytest-sanic) is a pytest plugin, it helps you to test your code asynchronously.
Just write tests like,
```python
async def test_sanic_db_find_by_id(app):
"""
Let's assume that, in db we have,
{
"id": "123",
"name": "Kobe Bryant",
"team": "Lakers",
}
"""
doc = await app.db["players"].find_by_id("123")
assert doc.name == "Kobe Bryant"
assert doc.team == "Lakers"
```
[pytest-sanic](https://github.com/yunstanford/pytest-sanic) also provides some useful fixtures, like loop, unused_port,
test_server, test_client.
```python
@pytest.yield_fixture
def app():
app = Sanic("test_sanic_app")
@app.route("/test_get", methods=['GET'])
async def test_get(request):
return response.json({"GET": True})
@app.route("/test_post", methods=['POST'])
async def test_post(request):
return response.json({"POST": True})
yield app
@pytest.fixture
def test_cli(loop, app, test_client):
return loop.run_until_complete(test_client(app, protocol=WebSocketProtocol))
#########
# Tests #

async def test_fixture_test_client_get(test_cli):
"""

"""
resp = await test_cli.get('/test_get')
assert resp.status == 200
resp_json = await resp.json()
assert resp_json == {"GET": True}
async def test_fixture_test_client_post(test_cli):
"""

resp = await test_cli.post('/test_post')

# Versioning
You can pass the `version` keyword to the route decorators, or to a blueprint initializer. It will result in the `v{version}` url prefix where `{version}` is the version number.
## Per route
You can pass a version number to the routes directly.
```python
from sanic import response
@app.route('/text', version=1)
def handle_request(request):
return response.text('Hello world! Version 1')
@app.route('/text', version=2)
def handle_request(request):
return response.text('Hello world! Version 2')
app.run(port=80)
```
Then with curl:
```bash
curl localhost/v1/text
curl localhost/v2/text
```
## Global blueprint version
You can also pass a version number to the blueprint, which will apply to all routes.
```python
from sanic import response
from sanic.blueprints import Blueprint
bp = Blueprint('test', version=1)
@bp.route('/html')
def handle_request(request):
return response.html('<p>Hello world!</p>')
```
Then with curl:
```bash
curl localhost/v1/html
```

WebSocket
=========
Sanic supports websockets, to setup a WebSocket:
.. code:: python
from sanic import Sanic
from sanic.response import json
from sanic.websocket import WebSocketProtocol
app = Sanic()
@app.websocket('/feed')
async def feed(request, ws):
while True:
data = 'hello!'
print('Sending: ' + data)
await ws.send(data)
data = await ws.recv()
print('Received: ' + data)
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8000, protocol=WebSocketProtocol)
Alternatively, the ``app.add_websocket_route`` method can be used instead of the
decorator:
.. code:: python
async def feed(request, ws):
pass
app.add_websocket_route(feed, '/feed')
Handlers for a WebSocket route are passed the request as first argument, and a
WebSocket protocol object as second argument. The protocol object has ``send``
and ``recv`` methods to send and receive data respectively.
You could setup your own WebSocket configuration through ``app.config``, like
.. code:: python
app.config.WEBSOCKET_MAX_SIZE = 2 ** 20
app.config.WEBSOCKET_MAX_QUEUE = 32
app.config.WEBSOCKET_READ_LIMIT = 2 ** 16
app.config.WEBSOCKET_WRITE_LIMIT = 2 ** 16
Find more in ``Configuration`` section.
