Learn to build web applications using Node.js and the Express framework.

Become a MEAN Stack Developer

Node.js is a runtime environment that enables JavaScript to run outside the browser. In this module, we'll learn the fundamentals of Node.js to build portable applications. We'll learn about the components of Node.js and make patterns using these. We'll also explore the API to learn how to create modules and write code for unique data files. Moreover, we'll delve into the features and practices of JavaScript and build a REST API using the Express framework from scratch. Moving on, we'll use Passport.js and JSON web tokens to establish authentication tokens. We’ll then create a live trivia game with Socket.IO. By the end of this module, we'll be equipped with extensive knowledge to build rich and comprehensive Node.js applications running on the server with JavaScript.
