Skip lefthook entirely if no changes in folder

[stychu]

Hi, I just found about left hook and would like to use it in my company project.
We have a monorepo with different technologies. One folder is app/ is intended for nodejs project on which I want to run commands before commiting a files.
I've a one problem tho. I want to run commands ONLY when any file in the app/ folder is changed/added/removed.
The lefthook should not even run when there are any other changes in the repo but no changes within app/

I managed to skipp the commands if not changes in app/ but this should not skip but rather not even RUN the lefthook as it takes around 5-10 seconds just to finish the lefthook process which other guys dont want to wait for unnecessarily.

How can I prevent lefthook from running in such case? Providing LEFTHOOK=0 git commit ... manually is NOT an option. I need this to be automatic based on changes from app/ folder

Hey! Do I properly understand the issue: lefthook executes and skips the steps as expected, but its execution takes too long?

How is lefthook installed on your system? It feels that lefthook is executed with npx and that's why it takes so much time. If this is the issue, consider installing it globally with any supported way.

Is it added to package.json as an NPM package? In that case, could you provide the sample project structure? The main question is: where node_modules folder locates related to the git root? It might be that for some reason it doesn't find an executable in node_modules and moves to npx fallback.

Please, provide a lefthook.yml config, so I am sure I haven't missed anything.

The general answer to your question is the following: lefthook must read the config to skip, so it must be executed at least to skip execution. So, the problem is - it should not take so much time just to be executed and skip.

Yess indeed I installed lefthook as npm dependency which is located in subfolder to the root folder.
After Installing lefthook from brew the check is instant now when its skipped. Work as I expected now.

Thank you !
