Developing Applications using ReactJS

This three-day course is designed for developers who are already familiar with JavaScript, including ES6, and wish to learn how to create User Interfaces using the ReactJS library. It will discuss how ReactJS can be used to create reusable, interactive UI components, single page applications using React Router and an introduction to Flux and Redux. The aim of the course is that delegates develop their skills, knowledge and understanding so that they can confidently use ReactJS to create User Interfaces.

Learning Objectives

Delegates will learn how to                    

  •   create components for use in a ReactJS application using JSX
  •   pass data around an application built in ReactJS
  •   how components can be used as part of single page applications


A solid understanding of JavaScript and preferably attendance at the following courses “Programming with JavaScript” and “Next Generation JavaScript: ECMAScript 2015” (or equivalent programming experience).

Please note: Before attending this class delegates must have a Microsoft account (signing up one is free).   The instructions on how to set up a Microsoft account can be found here.
