NodeJS Development
4 days
Overview
NodeJS is all about using JavaScript across the stack. With NodeJS you can use the same infrastructure/utilities for both client and server. NodeJS offers an impressive ecosystem of open source packages that can be combined to create a first-class server-side application.
During this 4-day course, we cover all the “must-know” details. We start with a brief introduction to NodeJS and then quickly step into core concepts like NPM, versioning, streams, testing, and more. At the end of the course, you will be able to develop server-side applications using NodeJS best practices.
