From the NPM Package Manager cheat sheet · Scripts & Task Running · verified Jul 2026
Running Scripts
Execute scripts defined in package.json
bash
# Run scripts from package.json
npm run build
npm run test
npm run dev
# Special scripts (no 'run' needed)
npm start
npm test
npm stop
npm restart
# Pass arguments to scripts
npm run test -- --watch
npm run build -- --production
# List available scripts
npm run
# Run pre/post scripts
# pretest runs before test
# postbuild runs after build🟢 Essential - Scripts automate common tasks
💡 Use -- to pass flags to the underlying command
📌 pre/post scripts run automatically
⚡ Special scripts (start, test) don't need "run"
