Node.js Essentials Course
2-day advanced JavaScript course in Node.js — NOD
JavaScript Training Course Overview
This Node.js training course, is targeted at web developers, who are good JavaScript programmers. It is designed as both a general introduction to the Node.js library, and as a practical introduction to using Node.js as a platform for building web applications.
This first half of this JavaScript training course concentrates the basics of installing, configuring and using Node.js, including: installing and using Node.js modules (NPM packages); creating and running command line JavaScript programs; creating, running, and interacting with customised web servers via the Connect library/framework.
The second half of the course takes delegates through the process of building and deploying a simple, but complete, web application using the Express.js library/framework. Through that process, students will learn how to manipulate JSON records; interact with databases; use websockets; emit and receive events via websockets; integrate and test their application.
