Learning Node.js

Course details

Node.js is a platform built on the Chrome JavaScript runtime that can help you build fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient—perfect for data-intensive real-time applications that run across distributed devices. In this course, learn the basics of Node.js, and discover how to build a simple application. Alexander Zanfir goes into topics such as npm, reading and writing files, and Node.js frameworks. He covers Node.js features, such as async/await, and dives into popular web development concepts. Alexander also walks through how to build a demo chat app from start to finish.
