What is the function of FOSUserBundle?

Question

symfony

We are considering the option of connecting the FOSUserBundle bundle to Symfony. In this regard, there are a number of clarifications on the purpose of this bundle.
I also ask you to share your experience with the new version of Symfon 4.
Many bundles are not yet available for it today, but perhaps this does not interfere with work
Tell me,
1. Does the bundle allow you to configure user roles and distribute access rights between them?
2. Why is it worth using a bundle, and not creating user authentication with rights distribution from scratch?
3. Do you have any idea when the bundle for Symphony 4 will be released?

Answer 1

1. No. The symphony has ACLs and waters. ACL is very slow (not only in symphony). Voters allow you to quickly make a system of rights, any one you want. symfony.com/doc/3.4/security/voters.html
2. For the same reason you should use symfony/laravel instead of writing your own framework.
It is too early to move to the four, it makes sense to wait for 4.1 or 4.2.
Personal experience with the quad is like this - after the release, the quartet switched to Laravel. For 4 years, the doctrine has not lived up to expectations - it eats memory like crazy, you still have to optimize everything by hand. The new distribution system (flex) puzzled me personally.
The only thing that we personally lack in Laravel is just the same waterers from the symphony.
