What is the best way to develop backend and frontend in git so that they do not depend on each other?

Question

git

Good afternoon. I develop a web service alone, I write both the back and the front myself. Question: how to correctly refer the structure of the git, so as not to connect the back and front? For example, so that at any time I can roll back to the previous commit on the front, but the back remains in its current state, and so on. Thank you.

Answer 1

you can keep front and back in different branches

Answer 2

The front is one service. Beck is second.
Should be in different repositories.
