I looked at the Roadmap and saw that CakePHP 4.1 will integrate PSR-11 containers and PSR-15 middleware. This makes me happy, because I think becoming more PSR compliant is the way to stay relevant/attract more users.

Now I wonder what the implementations might look like and where they are being discussed.

Questions regarding PSR-15:

- Will there be a general “middleware pipeline” for all requests/responses running through the application?
- Will there be a way to add middlewares to specific routes and will it replace your current “psr-7 middleware approach” in the router?

Question regarding PSR-11:

- Are you planning to write your own container?
- Or will you just implement the interfaces and let people register containers in the application bootstrapping?
- Will you eventually swap out “$this-\>loadComponent()” for “$this-\>container-\>get()” or will they co-exist?

Regards

Steffen

> Questions regarding PSR-15:

We still haven’t discussed the implementation details.

> Question regarding PSR-11:

We will most likely use an existing library instead of writing our own implementation. Usage like `$this->loadComponent()` will almost surely continue to exist.
