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 both class and functional 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 Formik 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.

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
  • Use lifecycle methods in class components
  • Take advantage of hooks in functional components
  • Work with controlled inputs and Formik
  • 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 and custom Hooks
