Good project structure for front & backend

[MarkoPavi]

Hey I got a question.
Say I have a backend project and a corresponding frontend project that communicates via REST. How do I make them both part of the same git repository or 2 repositories part of a git project. I already tried that but its just an issue tracker.
Is there a possibilty of a sub-repository? I just want them to be seperate when I commit/push but organized in the same folder neatly.
Sorry if its the wrong category any mods can freely move this accoringly.

I believe what you're looking for are git submodules.

In short if you run git submodule add <your-repo> in a git repository, <your-repo> will be added as a folder inside your main repository. You can add as many submodules as you like. You could even have private submodules in public repositories and they would not be visible to the public. An example of that could be seen in my dotfiles repository with the personal submodule.

Other than that you could also create a monorepo essentially combining both projects under the same repository which is common practice in certain situations as well. There are build systems dedicated to managing such repositories.
