Node NPM Scripts

This lesson is part of Node.js · All levels

Summary

NPM scripts allow you to run long commands via a short alias in package.json. You can make a start, test, build, or dev script that calls other tools like tsc, jest, or nodemon. That way, the whole team uses the same command and doesn't have to memorize the configuration of the tool.

Key points

Scripts are defined on the object scripts at package.json
Npm run is the name of the script running; npm start and npm test are special aliases
The script can run multiple commands at once with &&
Use pre<script> and post<script> to hook before/after
