App Building & Devbeginner
npm
Node Package Manager
Definition
The standard package manager for JavaScript. Used to install, update, and manage the third-party libraries (packages) your app depends on. Comes with Node.js.
Why it matters
npm gives you access to millions of pre-built tools, authentication, payment processing, email sending, so you're not coding everything from scratch.
Example
A founder runs npm install stripe to add Stripe's payment library to her app, then npm run build to prepare it for production.
