This repository contains a pure-Python implementation of a HTTP/2 protocol stack. It's written from the ground up to be embeddable in whatever program you choose to use, ensuring that you can speak HTTP/2 regardless of your programming paradigm.

You use it like this:

import h2.connection
import h2.config

config = h2.config.H2Configuration()
conn = h2.connection.H2Connection(config=config)
conn.send_headers(stream_id=stream_id, headers=headers)
conn.send_data(stream_id, data)
socket.sendall(conn.data_to_send())
events = conn.receive_data(socket_data)

This repository does not provide a parsing layer, a network layer, or any rules about concurrency. Instead, it's a purely in-memory solution, defined in terms of data actions and HTTP/2 frames. This is one building block of a full Python HTTP implementation.

To install it, just run:

$ python -m pip install h2
