As discussed in #1807.
Allowing the injection of WSGI middleware can enable easier migration
from Connexion 2 to Connexion 3. The use cases are limited though, as
this will only work for middleware that can work at the end of the
middleware stack.
Fixes#1697
Because of a wrong comparison against the position `Enum`, middleware
was not actually being added to the stack via `add_middleware`. This PR
fixes this, adds a warning when the middleware position cannot be found,
and adds a test.
Fixes#1682
This PR inspects the parameters of a Middleware class before passing in
the `lifespan` keyword argument. I was doubting to check the class
instead (`isinstance(LifespanMiddleware)`), but that's less flexible if
users want to write custom middleware to handle the lifespan.
This PR adds a new middleware to handle lifespan events.
I added this as a separate middleware so it is encapsulated and aligned
for both the `FlaskApp` and `AsyncApp`. It leverages a Starlette
`Router` to register and call the lifespan handler.
This PR refactors our tests to prepare the activation of our tests for
our AsyncApp.
The separate commits are atomic, which can be useful for reviewing.

This PR adds an interface for the ConnexionMiddleware, similar to the
interface of the Connexion Apps.
The Connexion Apps are now a simple wrapper around the
ConnexionMiddleware and framework app, delegating the work to the
middleware. This enables a similar interface and behavior for users when
using either the middleware or apps.
The arguments are repeated everywhere there is a user interface, but are
parsed in a central place. Repeating the arguments is not DRY, but
needed to provide users with IDE autocomplete, typing, etc. They are
parsed in a single `_Options` class, which also provides a mechanism to
set default options on an App level, and override them on the more
granular API level.
This makes the long list of provided parameters a lot more manageable,
so I would like to use it for the `Jsonifier` as well, and re-add the
`debug` and `extra_files` arguments which I have dropped in previous
PRs. I'll submit a separate PR for this.
I renamed the `options` parameter to `swagger_ui_options` since it only
contains swagger UI options. This is a breaking change though, and we'll
need to highlight this upon release.
We still have quite a lot of `App`, `MiddlewareApp`, and abstract
classes. It would be great if we could find a way to reduce those
further, or at least find better naming to make it more clear what each
one does 🙂 .
Finally, I added examples on how the middleware can be used with third
party frameworks under `examples/frameworks`. Currently there's an
example for Starlette and Quart, but this should be easy to extend. They
also show how the `ASGIDecorator` and `StarletteDecorator` from my
previous PR can be used.
