What is npm?
npm (Node Package Manager) is the world's largest software registry, offering over 2 million packages of reusable code for JavaScript developers. Owned by GitHub, npm provides essential tools and services for managing and sharing JavaScript code. It facilitates package management and version control, making it a cornerstone for modern JavaScript development.
How npm Works
npm allows developers to install, share, and manage code packages. Users can search for packages on the npm registry, install them into their projects using the npm CLI, and manage dependencies efficiently. Additionally, npm supports publishing your own packages, contributing to the open-source community. With npm, developers can ensure their projects use the latest and most reliable code.
What Problem npm Solves
npm addresses the complexities of JavaScript development by providing a centralized platform for code sharing and management. It simplifies the process of integrating third-party libraries, ensuring compatibility and version control. This reduces development time and effort, allowing developers to focus on building features rather than managing dependencies.
