Introduction
------------

**Autobahn\|Python** is a subproject of `Autobahn <http://crossbar.io/autobahn>`__ and provides open-source
implementations of

-  `The WebSocket Protocol <http://tools.ietf.org/html/rfc6455>`__
-  `The Web Application Messaging Protocol (WAMP) <http://wamp-proto.org/>`__

for Python 2 and 3, and running on `Twisted <http://twistedmatrix.com/>`__ and `asyncio <http://docs.python.org/3.4/library/asyncio.html>`__.

You can use **Autobahn\|Python** to create clients and servers in Python speaking just plain WebSocket or WAMP.

**WebSocket** allows `bidirectional real-time messaging on the Web <http://crossbario.com/blog/post/websocket-why-what-can-i-use-it/>`__ and beyond, while `WAMP <http://wamp-proto.org/>`__ adds real-time application communication on top of WebSocket.

**WAMP** provides asynchronous **Remote Procedure Calls** and **Publish & Subscribe** for applications in *one* protocol running over `WebSocket <http://tools.ietf.org/html/rfc6455>`__. WAMP is a *routed* protocol, so you need a **WAMP Router** to connect your **Autobahn\|Python** based clients. We provide `Crossbar.io <http://crossbar.io>`__, but there are `other options <https://wamp-proto.org/implementations/index.html#routers>`__ as well.

Features
--------

-  framework for `WebSocket <http://tools.ietf.org/html/rfc6455>`__ and `WAMP <http://wamp-proto.org/>`__ clients and servers
-  compatible with Python 2.7 and 3.4 or later (including 3.7)
-  runs on `CPython <http://python.org/>`__, `PyPy <http://pypy.org/>`__ and `Jython <http://jython.org/>`__
-  runs under `Twisted <http://twistedmatrix.com/>`__ and `asyncio <http://docs.python.org/3.4/library/asyncio.html>`__ - implements WebSocket
   `RFC6455 <http://tools.ietf.org/html/rfc6455>`__ and Draft Hybi-10+
-  implements `WebSocket compression <http://tools.ietf.org/html/draft-ietf-hybi-permessage-compression>`__
-  implements `WAMP <http://wamp-proto.org/>`__, the Web Application Messaging Protocol
-  high-performance, fully asynchronous implementation
-  best-in-class standards conformance (100% strict passes with `Autobahn Testsuite <http://crossbar.io/autobahn#testsuite>`__: `Client <http://autobahn.ws/testsuite/reports/clients/index.html>`__ `Server <http://autobahn.ws/testsuite/reports/servers/index.html>`__)
-  message-, frame- and streaming-APIs for WebSocket
-  supports TLS (secure WebSocket) and proxies
-  Open-source (`MIT license <https://github.com/crossbario/autobahn-python/blob/master/LICENSE>`__)

Native vector extensions (NVX)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Autobahn contains **NVX**, a network accelerator library that provides SIMD accelerated native vector code for WebSocket (XOR masking) and UTF-8 validation.

> NVX lives in namespace `autobahn.nvx` and currently requires a x86-86 CPU with at least SSE2 and makes use of SSE4.1 if available. The code is written using vector instrinsics, should compile with both GCC and Clang,and interfaces with Python using CFFI, and hence runs fast on PyPy.

Show me some code
-----------------

To give you a first impression, here are two examples. We have lot more `in the repo <https://github.com/crossbario/autobahn-python/tree/master/examples>`__.

WebSocket Echo Server
~~~~~~~~~~~~~~~~~~~~~

Here is a simple WebSocket Echo Server that will echo back any WebSocket
message received:

.. code:: python

    from autobahn.twisted.websocket import WebSocketServerProtocol
    # or: from autobahn.asyncio.websocket import WebSocketServerProtocol

    class MyServerProtocol(WebSocketServerProtocol):

        def onConnect(self, request):
            print("Client connecting: {}".format(request.peer))

        def onOpen(self):
            print("WebSocket connection open.")

        def onMessage(self, payload, isBinary):
            if isBinary:
                print("Binary message received: {} bytes".format(len(payload)))
            else:
                print("Text message received: {}".format(payload.decode('utf8')))

            # echo back message verbatim
            self.sendMessage(payload, isBinary)

        def onClose(self, wasClean, code, reason):
            print("WebSocket connection closed: {}".format(reason))

To actually run above server protocol, you need some lines of `boilerplate <https://autobahn.readthedocs.io/en/latest/websocket/programming.html#running-a-server>`__.

WAMP Application Component
~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is a WAMP Application Component that performs all four types of
actions that WAMP provides:

#. **subscribe** to a topic
#. **publish** an event
#. **register** a procedure
#. **call** a procedure

.. code:: python

    from autobahn.twisted.wamp import ApplicationSession
    # or: from autobahn.asyncio.wamp import ApplicationSession

    class MyComponent(ApplicationSession):

        @inlineCallbacks
        def onJoin(self, details):

            # 1. subscribe to a topic so we receive events
            def onevent(msg):
                print("Got event: {}".format(msg))

            yield self.subscribe(onevent, 'com.myapp.hello')

            # 2. publish an event to a topic
            self.publish('com.myapp.hello', 'Hello, world!')

            # 3. register a procedure for remote calling
            def add2(x, y):
                return x + y

            self.register(add2, 'com.myapp.add2')

            # 4. call a remote procedure
            res = yield self.call('com.myapp.add2', 2, 3)
            print("Got result: {}".format(res))

Above code will work on Twisted and asyncio by changing a single line
(the base class of ``MyComponent``). To actually run above application component, you need some lines of `boilerplate <https://autobahn.readthedocs.io/en/latest/wamp/programming.html#running-components>`__ and a `WAMP Router <https://autobahn.readthedocs.io/en/latest/wamp/programming.html#running-a-wamp-router>`__.
