How do I run specific commands for specific projects in one git repository?

[neptunecentury]

I have a git repository which contains two projects. One is an asp.net core web api, and the other is a frontend vue project. They are in separate directories under the main git repo directory.

My understanding is that a hook is executed per repository, so for example, if I configure a pre-commit hooks, any file that is staged and about to be committed will be passed in {staged_files} to my configured commands. The problem is, if I want to run my linter only for the frontend vue app and not the .net core files if I have any modified. But my linter and its configuration is installed in the vue app's directory.

How can I set up lefthook config to run the linter in the vue app directory ONLY when a file from that directory is staged?
I have been searching, and I think the glob configuration may help, but I am not sure how to set it up.

Thanks.

So, you want to run the linter only in a specific folder, right?

You can use root option. Besides filtering by directory it also changes the pwd to the given directory, so if you have the following project structure, you can use yarn lint {staged_files} and it will be executed in the vue directory:

.
├── dot-net/
├── lefthook.yml
└── vue/
    ├── package.json
    └── yarn.lock

Example lefthook.yml config

pre-commit:
  commands:
    lint:
      root: vue # filter by directory
      glob: "*.{ts,js}" # filter by glob
      run: yarn lint {staged_files}
