Difference between micro-framework and full-fledged?

Question

API

I decided not to reinvent the wheel, but to study the framework for my API. The question is what to study - my favorites are Slim and Laravel. Reasonings such - Slim is simple, and basically Route for API does. At the same time, there are a lot of laudatory reviews about Laravel (and Symphony). The question arises - what is the difference between MICRO and full?

Answer 1

Slim basically just gives you a router and nothing more.
Laravel - almost everything you need in the development process.

Answer 2

Micro - more lightweight. Loads fast. Eats little memory. Not overloaded with unnecessary functionality.
There is an analogue of Laravel micro framework Lumen. This is an official fork from Laravel.
PS I heard that Slim out of the box does not have a module for working with the database.
