Course 489:
Building Web Applications with React

(3 days)

 

Course Description

This course provides a hands-on guide to building fast, modern, scalable single page web applications (SPAs) using React. The students develop a React user interface using JSX, and create components leveraging props and state. The principles of Flux and unidirectional dataflow are explained, and then implemented using the Redux library. Students will gain an understanding of how to integrate RESTful AJAX calls React and Redux, as well as using the redux-form and redux-thunk libraries. By the end of the class, students will have walked through the process of building a single page application with React and be ready to apply that knowledge to applications they need to build at work.

Learning Objectives

At the end of this course, the participants will know how to:

  • Jump-start React applications with create-react-app
  • Build React components using JSX
  • Utilize props and state
  • Work with controlled inputs and redux-form
  • Add routes to their SPA using react-router
  • Unit Test React components
  • Implement the Flux design pattern using Redux
  • Make RESTful AJAX calls from React applications
  • Create Higher Order Components

Who Should Attend

This course is designed for web developers who are looking to build single page applications using React.

Prerequisites
