npm cheatsheet

npm (Node Package Manager) is the default package manager for Node.js. It allows you to install, update, and manage packages (libraries or modules) for your Node.js applications.

Install Node.js from nodejs.org, which includes npm. After installation, you can check the installed version of npm using the following command:

npm --version
# or
npm -v

npm init # Interactive setup
# or
npm init -y # Creates a package.json with default values

npm install
# or
npm i

npm install <package-name>              # Install and add to dependencies
npm install <package-name> --save-dev   # Add to devDependencies
npm install <package-name> -D           # Shorthand for --save-dev
npm install <package-name> -g           # Install globally
npm install <package-name>@<version>    # Install specific version
npm install <package-name>@latest       # Install latest version

npm uninstall <package-name>          # Uninstall package
