What are the responsibilities of the client and server side?

Question

PHP

Now the frontend is rapidly developing and the meaning of the backend is beginning to blur for me. It used to be easier, the server rendered the data on its side and issued it to the browser. But now JS is pulling this blanket over itself, and it’s not entirely clear to me what the server should do, except for binding to the database? I've only been in the web industry for 5 months, if anything, don't shout too much if I don't have the right understanding of the above...

Answer 1

If everything you do on the web comes down to CRUD, then the role of the backend in your work can come down to:
When you come across heavier applications with some business logic (even!), then you will realize that the front-end takes up as much of a project as the Start button does in the entire Windows OS.

Answer 2

Well, for example, I write a service! The backend will only return data from the database, maybe slightly modified! And drawing everything on the client side

Answer 3

So the point is that values ​​change over time, there was no such thing as a front-end at all.
Just remember that
1. backend - logic on the server
2. frontend - logic on the client
3. layout - templates without logic in the browser
And where, what, where renders is no longer important.
