+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at sanic-maintainers@googlegroups.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.

+# 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.

 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.

-Benchmarks

-All tests were run on an AWS medium instance running ubuntu, using 1
-process. Each script delivered a small JSON response and was tested with
-wrk using 100 connections. Pypy was tested for Falcon and Flask but did
-not speed up requests.

-# Configuration
-
-Any reasonably complex application will need configuration that is not baked into the acutal 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 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_file(/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 varibales 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 (sec) |

+## 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 .authors import authors
+
+content = Blueprint.group(static, authors, url_prefix='/content')

+
+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')

+

+# 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

+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.

+# 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):

+
+            if is_authorized:
+                # the user is authorized.

+# 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
+```

+## 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)

+## WebSocket routes
+
+Routes for the WebSocket protocol can be defined with the `@app.websocket`
+decorator:

+        data = 'hello!'
+        print('Sending: ' + 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')

+
+## 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

 ```
 
-Note: currently you cannot build a URL for a static file using `url_for`. 
+> **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

+## 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])

+# 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>')

+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.
