Application life cycle

Peak application are Middlewares centric. You can resume the flow like this. A user proceed a HTTP Request, then it is forwarded to your application HTTP stack which resolve it and return a HTTP response whenever possible.

If a Middleware issue a HTTP response, the application HTTP stack will be stopped and the response returned.

There is two outcomes possible when the main HTTP stack is resolved:

• It stop when a PSR-7 Response is returned.
• It throw an exception because no response have been returned.
