NodeJS Introductory Course For Absolute Beginners

Node.js is a JavaScript runtime that brings JavaScript to the back end, handles server-side requests and responses, enabling web apps, standalone command line applications, real-time chat, and internet of things.

Understand how node.js, a JavaScript runtime built on Chrome's V8 engine, uses an event driven non blocking IO model for lightweight efficiency.

Discover how Node.js powers back ends for startups to Fortune 500 companies, including LinkedIn mobile. See why PayPal, Netflix, Trello, and Uber rely on Node.js.

Install Node.js on Windows with the installer, choose the LTS version, install build tools, and verify with node -v and npm -v before rebooting.

Learn to install Node.js on Ubuntu via official installer, apt-get, PPA, or NVM for flexible version management, and verify with node -v and npm -v.

Learn how npm is the Node.js package manager, usable from command line, with npm registry hosting third-party modules; Node.js provides core modules, and you can publish modules built on them.

Explore the Node.js Ripple repl, a read-evaluate-print loop that runs code, prints output, explores modules, and supports editor mode, dot commands, saving sessions, and recalling previous outputs.

Create a hello world file, log Hello World to the console, save, and run node to see the output in the terminal. Node executes JavaScript code without front-end script tags.

Explore Node.js core modules such as OS, FS, and HTTP, and learn how fs.readFile uses an error-first callback to read a file and convert a buffer to a string.

Create a node web server using the core http module, define a createServer callback with request and response, and send a hello message on port 4000.

Learn to build rest APIs with Express.js, exposing get, post, put, and delete routes, serve a static site, and test calls with Postman using Node.js.

Install postman on Windows or Ubuntu and use it to test get, post, put, and delete calls to localhost 4001, while enabling express.json to parse request bodies.

Discover Node.js basics, including core modules fs and http, build and run a web server with Express, and serve static sites and rest APIs, using Postman for API calls.
