What is npm? (Node Package Manager)

npm (short for “Node Package Manager”) is a package manager for the JavaScript programming language. It is the default package manager for the JavaScript runtime environment Node.js.

npm is used to manage packages (libraries, tools, and frameworks) that are used in Node.js applications. It helps developers to easily share, reuse, and maintain code, and to automate the process of installing, updating, and managing packages.

npm consists of a command-line interface (CLI) and a registry of published packages. To use npm, you need to have Node.js installed on your computer.

Here are a few common npm tasks:

  • Installing packages: To install a package from the npm registry, you can use the npm install command. For example, to install the “lodash” package, you would type npm install lodash. This will download the package and add it to your project’s node_modules directory.
  • Updating packages: To update a package to the latest version, you can use the npm update command. For example, to update the “lodash” package, you would type npm update lodash.
  • Uninstalling packages: To uninstall a package, you can use the npm uninstall command. For example, to uninstall the “lodash” package, you would type npm uninstall lodash.

I hope this helps to give you an understanding of what npm is and how it is used! Let me know if you have any questions or need further assistance.
