Laravel Middlewarize

:ribbon: Chain of Responsibility Design Pattern In Laravel Apps :ribbon:

You can use middlewares to decorate any method calls on any object.

:fire: Installation:

:arrow_forward: How to use:

Put the \Imanghafoori\Middlewarize\Middlewarable trait on your class.

For example consider a simple repository class:

:arrow_forward: Define a Middleware:

Since middlewares are resolved out of the laravel container, you can pass any abstract string as a middleware and bind it on the IOC:

:arrow_forward: Use the Middleware:

Cleaned controller will look like this:

Easy Peasy Yeah ?!

You totally separate the cache concern into a new class.

So let's compare...

Before:

Before utilizing middlewares our code was like this:

:arrow_forward: Overriding default Middleware method:

:arrow_forward: Multiple middlewares:

The order of execution is like that:

Start ===> ( middle1 -> middle2 -> middle_3 ( find ) middle_3 -> middle2 -> middle1 ) ===> result !!!

:arrow_forward: Middlewares on facades ?!

You wanna use facades to call the repo ?! No problem.

:arrow_forward: Objects as middlewares:

You can also use objects as middlewares for more eloborated scenarios.

:arrow_forward: Middleware on static methods:

:arrow_forward: Testing:

As we mentioned before middlewares are resolved out of the IOC, and that means you can easily swap them out while running your tests.

Here we have neutralized the middleware to do "nothing" while the tests are running.

:arrow_forward: What happens if exception is thrown from your method?

It is important to know if you throw an exception in your method, the post middlewares still execute and the value of $value = $next(data) would be the thrown exception. The exception is rethrown when all middlewares finished executing.
