HTTP/2.0 for Python

Project description

HTTP is changing under our feet. HTTP/1.1, our old friend, is being supplemented by the brand new HTTP/2.0 standard. HTTP/2.0 provides many benefits: improved speed, lower bandwidth usage, better connection management, and more.

hyper provides these benefits to your Python code. How? Like this:

from hyper import HTTP20Connection

conn = HTTP20Connection('')
conn.request('GET', '/')
resp = conn.getresponse()



Caveat Emptor!

Please be warned: hyper is in a very early alpha. You will encounter bugs when using it. In addition, there are very many rough edges. With that said, please try it out in your applications: I need your feedback to fix the bugs and file down the rough edges.


hyper provides support for draft 9 of the HTTP/2.0 draft specification and draft 5 of the HPACK draft specification. As further drafts are released, hyper will be updated to support them.


hyper is intended to be a drop-in replacement for http.client, with a similar API. However, hyper intentionally does not name its classes the same way http.client does. This is because most servers do not support HTTP/2.0 at this time: I don’t want you accidentally using hyper when you wanted http.client.


hyper welcomes contributions from anyone! Unlike many other projects we are happy to accept cosmetic contributions and small contributions, in addition to large feature requests and changes.

Before you contribute (either by opening an issue or filing a pull request), please read the following guidelines:

  1. Check for issues, both open and closed, before raising a new one. It’s possible your idea or problem has been discussed before. GitHub has a very useful search feature: I recommend using that for a few minutes.

  2. Fork the repository on GitHub.

  3. Run the tests to confirm that they all pass on your system. If they don’t, you will need to investigate why they fail. hyper has a substantial suite of tests which should cover most failures.

  4. Write tests that demonstrate your bug or feature. Ensure that they all fail.

  5. Make your change.

  6. Run the entire test suite again, confirming that all tests pass including the ones you just added.

  7. Send a pull request. GitHub pull requests are the expected method of collaborating on this project.

If for whatever reason you strongly object to the GitHub workflow, email the maintainer with a patch.
