I'd like to know if it makes sense to divide the project I'm working on in two repositories instead of one.
From what I can say:
- Frontend will be written in html+js
- Backend in .net
- The backend doesn't depend on frontend and the frontend doesn't depend on the backend
- The frontend will use a restful api implemented in the backend.
- The frontend could be hosted on any static http server.
As of now, the repository has this structure:
I think it's a mistake to keep both project in the same repository. Since both project do not have dependencies between each others, they should belong in individual repositories and if needed a parent repository that has submodules.
I've been told that it's pointless and that we won't get any benefit from doing that.
Here are some of my arguments:
- We have two modules that don't depend between each others.
- Having source history of both projects in the long term may complicate things (try searching in the history for something in the frontend while you have half of the commits that are completely unrelated to the bug you're looking for)
- Conflict and merging (This shouldn't happen but having someone pushing to the backend will force other developer to pull backend changes to push frontend changes.)
- One developer might work only on the backend but will always have to pull the backend or the other way around.
- In the long run, when it will be time to deploy. In some way, the frontend could be deployed to multiple static server while having one backend server. In every case, people will be forced to either clone the whole backend with it or to make custom script to push to all servers the frontend only or to remove the backend. Easier to just push/pull only the frontend or backend than both if only one is needed.
- Counter argument (One person might work on both projects), Create a third repo with submodule and develop with it. History is kept seperated in individual modules and you can always create tags where version of backend/frontend do really work together in sync. Having both frontend/backend together in one repo doesn't mean that they will work together. It's just merging both history into one big repo.
- Having frontend/backend as submodules will make things easier if you want to add a freelancer to the project. In some case, you don't really want to give full access to the codebase. Having one big module will make things harder if you want to restrict what the "outsiders" can see/edit.
- Bug introduction and fixing bug, I inserted a new bug in the frontend. Then someone fix a bug in the backend. With one repository, rolling back before the new bug will also rollback the backend which could make it difficult to fix. I'd have to clone the backend in a different folder to have the backend working while fixing the bug in the frontend... then trying to remerge things up... Having two repository will be painless because moving the HEAD of one repo won't change the other. And testing against different version of backend will be painless.
Can someone give me more arguments to convince them or at least tell me why it is pointless (more complicated) to divide the project in two submodules. The project is new and the codebase is a couple of days old so it's not too soon to fix.
