npm

npm is the world’s largest software registry with over 2.5 million packages and 20 billion weekly downloads, powering JavaScript development for companies like Netflix, Airbnb, and PayPal. As Node.js’s official package manager, it’s the backbone of modern web development and the largest open source ecosystem.

What makes npm exceptional is its combination of vast package ecosystem with sophisticated dependency management - semantic versioning, security auditing, and workspace support handle complex project requirements. The registry’s scale and quality make JavaScript development incredibly productive.

JavaScript developers choose npm because it eliminates the need to build everything from scratch. From simple utilities to complex frameworks, the ecosystem provides battle-tested solutions that accelerate development and reduce time-to-market.
