onchange fire by itself (ts-node related)

I use onchange in npm script to watch file changes to re-run tests.

I notice for some reason onchange has detect changes out of nowhere and keep rerunning the tests

I look at the files and notice .git/FETCH_HEAD is updating continuously. I believe it is done by VSCode.

However, my onchange call does not listen to the .git folder (of course). My call is onchange -w -i \"src/**/*.ts\ -- npm run test-spec

I tried to exclude the folder onchange -w -i \"src/**/*.ts\" -e \"**/.DS_Store\" -e \".git/*\" -- npm run test-spec but it still keep running by itself. So FETCH_HEAD may not be the cause.

You can see / try the call here: https://github.com/typings/core/tree/add-jspm

Don’t know if it would be reproducible.

Thank! That’s really helpful.

I discovered the issue is within the project test cases themselves.

{{event}} and {{changed}} are templates that get replaced anywhere in the command after the --. You could try something like /bin/sh -c "echo '{{event}} to {{changed}}' && my-command" to combine two commands. You’ll have to make sure you escape the double quotes properly, if you put that in your package.json file.
