What is npm? Nedir?
npm (Node Package Manager) is the default package manager for JavaScript and Node.js ecosystem and the world's largest software registry.
npm was developed by Isaac Z. Schlueter in 2010 and is distributed as the default package manager with Node.js. The npm registry hosts over 2 million JavaScript packages, making it the world's largest software registry. npm manages project dependencies, scripts, and metadata through the package.json file. Dependency versions are controlled with semantic versioning (semver). The npm install command downloads dependencies to the node_modules directory and ensures exact version locking with package-lock.json. The npm CLI provides functions like package installation/removal, script execution, package publishing, security auditing (npm audit), and monorepo management with workspaces. The npx command allows running packages directly without installation. Acquired by GitHub (Microsoft) in 2020, npm is the backbone of the JavaScript ecosystem. Billions of downloads occur weekly. Popular packages like React, Express, lodash, and axios are distributed through npm.
