npm

npm (Node Package Manager) is the default package manager for Node.js, created by Isaac Z. Schlueter in 2010. It consists of a command-line tool for installing and managing dependencies and the npm registry — the world's largest software registry with over two million packages.

npm uses a package.json file to declare dependencies and scripts, and a package-lock.json for reproducible installations across environments. The CLI handles dependency resolution, version management, and script execution. npm ships with every Node.js installation and remains the most widely used JavaScript package manager. The documentation covers all CLI commands and configuration options.
