Hypercorn is an `ASGI
<https://github.com/django/asgiref/blob/main/specs/asgi.rst>`_ and
WSGI web server based on the sans-io hyper, `h11
<https://github.com/python-hyper/h11>`_, `h2
<https://github.com/python-hyper/hyper-h2>`_, and `wsproto
<https://github.com/python-hyper/wsproto>`_ libraries and inspired by
Gunicorn. Hypercorn supports HTTP/1, HTTP/2, WebSockets (over HTTP/1
and HTTP/2), ASGI, and WSGI specifications. Hypercorn can utilise
asyncio, uvloop, or trio worker types.

Hypercorn can optionally serve the current draft of the HTTP/3
specification using the `aioquic
<https://github.com/aiortc/aioquic/>`_ library. To enable this install
the ``h3`` optional extra, ``pip install hypercorn[h3]`` and then
choose a quic binding e.g. ``hypercorn --quic-bind localhost:4433
...``.

Hypercorn was initially part of `Quart
<https://github.com/pgjones/quart>`_ before being separated out into a
standalone server. Hypercorn forked from version 0.5.0 of Quart.

Quickstart
----------

Hypercorn can be installed via `pip
<https://docs.python.org/3/installing/index.html>`_,

.. code-block:: console

    $ pip install hypercorn

With hypercorn installed ASGI frameworks (or apps) can be served via
Hypercorn via the command line,

.. code-block:: console

    $ hypercorn module:app

Alternatively Hypercorn can be used programatically,

.. code-block:: python

    import asyncio
    from hypercorn.config import Config
    from hypercorn.asyncio import serve

    from module import app

    asyncio.run(serve(app, Config()))
