This package seems quite useless without this feature, or I'm completely missing how to use it. My command runs an express server and a restart will try to start that server again causing port conflicts. I've tried to listen to various process events, but nothing appears to be fired.

In the end I ended up implementing chokidar through a js file.

I worked around this issue by using pkill to terminate the process in the -c command.

"scripts": {
  "watch-server": "chokidar --initial 'src/*.ts' 'src/server/**/*.ts' -c 'pkill -f \"yarn.js run-server\" ; yarn run-server'",
}

Use pgrep -f "..." first to test what search string you should use. This only worked for me because the yarn run-server bit is actually first turned into yarn.js ... by the shell, so the string I use to find the command to kill is slightly different than the chokidar process (which you don't want to terminate).

@connorjclark this worked for me, but for Yarn 3 I needed to adjust it to accommodate the version number and different extension in the yarn script:

… -c \"pkill -f 'yarn-.*.cjs <script>'; yarn <script>\"
