In what cases should you use an MVC frontend and MVC backend framework together?

Question

JavaScript

I’ll make a reservation right away that my knowledge of MVC front-end frameworks is rather poor, so the wording of the question can be a little confusing.
Here I use the MCV framework in PHP, for example, Symfony. The model is entities, in the controllers I have business logic, in them I filter and dump data onto the view - twig templates. Accordingly, depending on the parameters specified in the get-request or directly in the route, different data is selected, and it seems that on the twig-view, I just have to set the conditions / cycles.
In what cases would I need a front-end framework like AngularJS? Are there any typical examples of such usage?

Answer 1

If this is not a trendy SPA, then the function of angular and other reacts is to get in the way.

Here is an article on habré. It is a translation. I think there is something that interests you.

Answer 3

Rendering pages on the server and SPA are mutually exclusive things. Either you render pages on the server and then you do not need SPA, or vice versa - on the server you have only one view (twig template), and everything else is rendered on the server side using angular or other frameworks.
