Connexion enters the ASGI ecosystem with the release of Connexion 3 🎉

[RobbeSneyders]

Hi Starlette peeps 👋

We just released Connexion 3, which is implemented as an ASGI middleware stack using Starlette as an ASGI toolkit.

It has been a real joy to build with Starlette. It is one of the most elegant packages I've worked with, but also the documentation, issues, and discussions are a big help when entering the ASGI ecosystem. So we want to both thank and congratulate you for this!

We'd appreciate any feedback and would be very open to collaborate going forward! you can check our blogpost for more details on the design and implementation.

Some info on Connexion

Connexion is a popular Python web framework (~ 5 million downloads per month) that makes spec-first and api-first development easy. You describe your API in an OpenAPI (or swagger) specification with as much detail as you want and Connexion will guarantee that it works as you specified

Connexion 3 fundamentally changes how Connexion is designed and implemented, and how it fits into the wider Python API ecosystem. We adopted the ASGI interface, which makes Connexion both modular and well-integrated with most modern Python API tooling.

Connexion 3 brings some major changes compared to 2.X:

• The improved App and new AsyncApp allow you to use Connexion as a stand-alone framework
  • The App interface was extended so you no longer have to care about the framework used
    underneath
• Connexion can now be used as middleware to supercharge any ASGI or WSGI-compatible framework
  with its spec-based functionality
• Connexion is now pluggable in many dimensions:
  • All Connexion functionality is pluggable by adding or removing middleware from its stack
  • Validation is now pluggable by content type, solving longstanding issues regarding endpoints
    with multiple content types and making it easy to add validation for additional content types
  • Authentication is now pluggable by security scheme, making it easy to customize the behavior or
    add support for additional security schemes.
• Aiohttp support has been dropped due to lack of ASGI support
• We spent a lot of effort on extending and improving our documentation_
