# 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
)
```
