What is ``websockets``?
-----------------------
``websockets`` is a library for building WebSocket servers_ and clients_ in
Python with a focus on correctness and simplicity.
.. _servers: https://github.com/aaugustin/websockets/blob/master/example/server.py
.. _clients: https://github.com/aaugustin/websockets/blob/master/example/client.py
Built on top of ``asyncio``, Python's standard asynchronous I/O framework, it
provides an elegant coroutine-based API.
`Documentation is available on Read the Docs. <https://websockets.readthedocs.io/>`_
Here's how a client sends and receives messages:
.. copy-pasted because GitHub doesn't support the include directive
.. code:: python
#!/usr/bin/env python
import asyncio
import websockets
async def hello(uri):
async with websockets.connect(uri) as websocket:
await websocket.send("Hello world!")
await websocket.recv()
asyncio.get_event_loop().run_until_complete(
hello('ws://localhost:8765'))
And here's an echo server:
.. code:: python
#!/usr/bin/env python
import asyncio
import websockets
async def echo(websocket, path):
async for message in websocket:
await websocket.send(message)
asyncio.get_event_loop().run_until_complete(
websockets.serve(echo, 'localhost', 8765))
asyncio.get_event_loop().run_forever()
Does that look good?
`Get started with the tutorial! <https://websockets.readthedocs.io/en/stable/intro.html>`_
Why should I use ``websockets``?
--------------------------------
The development of ``websockets`` is shaped by four principles:
1. **Simplicity**: all you need to understand is ``msg = await ws.recv()`` and
``await ws.send(msg)``; ``websockets`` takes care of managing connections
so you can focus on your application.
2. **Robustness**: ``websockets`` is built for production; for example it was
the only library to `handle backpressure correctly`_ before the issue
became widely known in the Python community.
3. **Quality**: ``websockets`` is heavily tested. Continuous integration fails
under 100% branch coverage. Also it passes the industry-standard `Autobahn
Testsuite`_.
4. **Performance**: memory use is configurable. An extension written in C
accelerates expensive operations. It's pre-compiled for Linux, macOS and
Windows and packaged in the wheel format for each system and Python version.
Documentation is a first class concern in the project. Head over to `Read the
Docs`_ and see for yourself.
.. _Read the Docs: https://websockets.readthedocs.io/
.. _handle backpressure correctly: https://vorpus.org/blog/some-thoughts-on-asynchronous-api-design-in-a-post-asyncawait-world/#websocket-servers
.. _Autobahn Testsuite: https://github.com/aaugustin/websockets/blob/master/compliance/README.rst
Why shouldn't I use ``websockets``?
-----------------------------------
* If you prefer callbacks over coroutines: ``websockets`` was created to
provide the best coroutine-based API to manage WebSocket connections in
Python. Pick another library for a callback-based API.
* If you're looking for a mixed HTTP / WebSocket library: ``websockets`` aims
at being an excellent implementation of :rfc:`6455`: The WebSocket Protocol
and :rfc:`7692`: Compression Extensions for WebSocket. Its support for HTTP
is minimal — just enough for a HTTP health check.
* If you want to use Python 2: ``websockets`` builds upon ``asyncio`` which
only works on Python 3. ``websockets`` requires Python ≥ 3.6.1.
