A screamingly fast, ultra-lightweight WSGI_ server for CPython 2 and CPython 3,

written in C using Marc Lehmann's high performance libev_ event loop and

Ryan Dahl's http-parser_.

Why It's Cool

~~~~~~~~~~~~~

bjoern is the *fastest*, *smallest* and *most lightweight* WSGI server out there,

featuring

* ~ 1000 lines of C code

* Memory footprint ~ 600KB

* Python 2 and Python 3 support (thanks @yanghao!)

* Single-threaded and without coroutines or other crap

* Can bind to TCP `host:port` addresses and Unix sockets (thanks @k3d3!)

* Full persistent connection ("*keep-alive*") support in both HTTP/1.0 and 1.1,

  including support for HTTP/1.1 chunked responses

Installation

~~~~~~~~~~~~

``pip install bjoern``. See `wiki `_ for details.

Usage

~~~~~

Flask example

-------------

.. code-block:: python

   from flask import Flask

   app = Flask(__name__)

   @app.route("/")

   def hello_world():

       return "Hello, World!"

   if __name__ == "__main__":

       import bjoern

       bjoern.run(app, "127.0.0.1", 8000)

Advanced usage

--------------

.. code-block:: python

   # Bind to TCP host/port pair:

   bjoern.run(wsgi_application, host, port)

   # TCP host/port pair, enabling SO_REUSEPORT if available.

   bjoern.run(wsgi_application, host, port, reuse_port=True)

   # Bind to Unix socket:

   bjoern.run(wsgi_application, 'unix:/path/to/socket')

   # Bind to abstract Unix socket: (Linux only)

   bjoern.run(wsgi_application, 'unix:@socket_name')

   # Enable statsd metrics. See instrumentation.md for details.

   bjoern.run(wsgi_application, host, port, statsd=...)

Alternatively, the mainloop can be run separately:

.. code-block:: python

   bjoern.listen(wsgi_application, host, port)

   bjoern.run()

   # With metrics. See instrumentation.md for details.

   bjoern.listen(wsgi_application, host, port)

   bjoern.run(statsd=...)

You can also simply pass a Python socket(-like) object. Note that you are responsible

for initializing and cleaning up the socket in that case.

.. code-block:: python

   bjoern.server_run(socket_object, wsgi_application)

   bjoern.server_run(filedescriptor_as_integer, wsgi_application)

   # This needs manual compilation with `WANT_STATSD=yes`

   bjoern.server_run(socket_object, wsgi_application, enable_statsd=True)
