Middleware

TODO: ????

types of middleware​

There are 3 types of middlewares you can create:

functional middlewares​

similar to expressjs middlewares they are just functions that are executed at each request. the major point is you need to call await next(), otherwise you can break the promise chain and cause unpredictable behaviors.

Middleware Class​

it is a class definition that extends Middleware class. Everytime a request is processed, a new instance of this class is created before executing the middleware part. This is ideal for when you need to run a middleware where it needs to track some data from before and acter controller execution per each request.

Middleware Object​

There may exists situations where you want to save performance and not instantiate on every request. or you want to be able to track data between requests.

order of middleware execution​

  1. from global router
  2. from class middlewares
  3. from request method of controller class
