Description

At #547, I mistakenly assumed that watch mode was not working because of esm, in fact, watch mode is not working if the project is in the git worktree.
If you use typescript, then typescript rebuilds the project, but the server still does not restart.

Steps to Reproduce

git clone https://github.com/railwayapp-templates/fastify --bare
cd fastify.git
git worktree add main
cd main
npm i
npm run dev

change any file -> typescript rebuild -> server does not restart

Expected Behavior

No response

What's special with worktree that breaks this? We just use normal OS file watching.

I'm not sure what the problem is, so far I'm using nodemon. It works with worktree.

I couldn't reproduce this on my end, I followed the steps you listed.

My environment:

• OS → Windows 10 (21H1)
• Node Version → 16.17.0
• Fastify-CLI Version → 5.4.2

I think the source of the issue starts from here:
nodejs/node#36005

and leads to the chokidar module's funding

If we drop that module, we should go for the node:fs.watch one
