PID-tracking / kill-signal support

[ELLIOTTCABLE]

So, this might be a little out-of-scope, but I figured I'd point out it's a desirous feature:

It'd be nice if chokidar could automatically kill (or better yet, send an arbitrary single to) the previous invocation when it starts a new one. (For instance, when a test-file is changed before a long-running test suite is complete; or in my particular use-case, allowing me to wrap the desired command in less and wanting the less-instance to be killed when chokidar invokes a new instance of the command.)

I think this would be a good addition to chokidar-cli and I'm willing to merge a PR if someone wants to implement this feature.

If it helps anyone, nodemon does this out of the box, e.g.:

nodemon --watch . --exec "eslint --cache ."

I achieved it by adding few scripts in package.json

"scripts": {
    "start": "node myapp.js",
    "kill": "pkill -f myapp.js",
    "restart": "npm run kill; npm run start;",
    "watch": "./node_modules/.bin/chokidar --initial '**/*.js' -c 'npm run restart'"
}

Now just run:

npm run watch
