Quick Start Guide Node JS for Beginners Getting started

Explore a fast-paced introduction to Node.js, learning how to set up development environments, run your first Node.js file, and use modules, file I/O, and a basic web server.

Begin by setting up your environment for node.js, including downloading node.js, choosing an editor, and using the terminal. Learn to use npm and verify installation before moving on.

Navigate to your node project directory, create app.js, write a console.log output, and run node app.js to see Hello printed in the terminal, proving server-side JavaScript basics.

Explore the global object, console, and process in node.js, inspect the directory name and file name, and use process.argv to read and pass command-line arguments to build dynamic messages.

Explore the node.js process object to output content with process.stdout, read input via process.stdin, generate random values from an array, and exit with process.exit using template literals and arrow functions.

Build a Node.js number guessing game from 1 to 10 using Math.floor and Math.random, prompting via process.stdout, reading input with process.stdin, and looping until the correct guess is reached.

Learn to implement a countdown timer in Node.js using setTimeout and setInterval, with terminal output via process.stdout and template literals that update every second.

Learn to bring modules into node applications, use core modules such as path and util via require, and export custom modules from a mods folder for reuse.

Learn how to read and write files in node using the fs module, including reading directories with read directory sync, reading files with utf-8 encoding, and overwriting files with error handling.

Build a node.js http server from the back end, setting localhost port, handling request urls, and sending html with content-type text/html and hello world output in the browser.

Create an index HTML page in the mods folder and render its contents in the browser using the FSS module.

Extend a node js server by integrating the url module to map requests to html files using the base url and path name, and implement 404 not found handling.

Explore the node package manager to install and manage packages like lodash, create a package.json, and use lodash utilities such as random, shuffle, and times in a node app.

Install express via npm, create a basic node app, require express, set up a port (3000), define a hello world route, and validate with a ready output.

Master the essentials of getting started with Node, tools, modules, and web servers. Use the included source code and resources to run code in your terminal and build Node applications.
