@olegjs/on-change v3.0.1

on-change

CLI tool to run a command if file has changed since the last time that command was run.

Forgetting to run npm i or npm ci every time after git pull or switching between branches and getting Error: Cannot find module...? Add the following to package.json to automate this chore.

"scripts": {
  "prestart": "npx @olegjs/on-change --file package-lock.json npm ci"
}

This CLI tool stores a file checksum in a hidden sha file every time it run a given command. Made to automate running npm ci after pulling modified package-lock.json.
