NPM for Beginners - Fast Track

Master the fundamentals of npm for JavaScript beginners, including installing npm, using core commands, and downloading packages from the npm registry to get up and running quickly.

Take action by writing code, trying solutions, and asking questions after you try. Finish what you start, build consistent habits, and tackle the hardest parts first to succeed in programming.

Install Node.js to get npm, verify versions with node -v and npm -v, and use the terminal or command prompt to install JavaScript packages.

Learn how to use npm help to access commands and documentation. Explore usage, search commands, and distinguish online docs from local help.

Learn to initialize a new project with npm, create and understand a package.json, and explore directory setup and installing packages for a JavaScript project.

Initialize a project with npm init, install packages like express, and explore node_modules and dependencies, generating a working package.json and ready-to-use Express setup.

Learn how to manage development dependencies in npm, using the -D or --save-dev flag to install packages needed only during development, not production.

Learn to install specific package versions with npm install, using exact version pins like express@3.3.3, or fetch the latest version; manage uninstalls and version constraints.

Learn how to uninstall packages in npm by removing them from dependencies or devDependencies in package.json, then run npm install to update the project.

Learn how to uninstall global npm packages and distinguish global versus local installs, including using npm install -g, permissions with sudo, and global paths on macOS and Windows.

Learn to list npm packages, view local and global dependencies with npm list, and control depth to inspect package trees and their dependencies.

You can delete the project folder and still recover by running npm install to recreate node_modules from package.json. Back up the package.json and reinstall the desired versions when needed.

Learn to run npm scripts by using the scripts field in package.json, invoking named scripts like start or test with npm run, and executing files via node for simple apps.

Update npm to the latest version using npm install npm@latest, with sudo on Mac when prompted, and troubleshoot by restarting the terminal or running from outside the project.

Search the npm registry to discover packages, view descriptions and authors, and install them with npm install to add functionality like animations or directory helpers to your project.

Learn how to install a package, require it in node, and run a quick random number example to explore npm packages and basic usage.
