 # 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):
-        response.write('foo,')
-        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)'):
-                response.write(record[0])
-
-    return stream(stream_from_db)
-```

 ## 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.
