Advanced JavaScript & Node.js Training Course

Overview

Course

This workshop teaches the participants how to design and develop server side applications using the event-driven, non-blocking model framework Node.js. This program inducts the participant in some of the advanced concepts of the JavaScript language so that the participant is well equipped to build end-to-end application using JavaScript.

Objectives

At the end of this training course, the participants will:

Understand the non-blocking nature of Node.js
Writing asynchronous code with callbacks and streams
Learn how to modularize code using NPM and require()
Learn how to build web api using Express.js •Learn how to build real
Understand and take advantage of the built-in apis for building scalable few applications
Learn how to build web api using Express.js
Learn how to build real-time applications using WebSockets and socket.io
