A couple of questions about Symfony 4?

Question

symfony

Hello. I decided to learn Symfony 4, but immediately got confused:
1) what is Symfony flex and how is it different from Symfony 4?
2) what is the difference between symfony/skeleton and symfony/website-skeleton (this is from off-docs)?
3) Symfony 4 is a microframework and requires separate components to extend, right?
Thank you all in advance for your replies!

Answer 1

1) what is Symfony flex and how is it different from Symfony 4?

flex is a compositor plugin, part of symfony 4.

2) what is the difference between symfony/skeleton and symfony/website-skeleton (this is from off-docs)?

Look at the contents of a single file. The second is more tuned to a typical site, while the first is minimalist.
Both options are much more flexible than the old skeletons with lots of files.

3) Symfony 4 is a microframework and requires separate components to extend, right?

Yes. But these components are also parts of Symfony 4.
Symfony 4 is a framework, a microframework, and a library of components at the same time.
