Mastering React | React Essentials, Redux, Hooks, JSX, Forms, Unit Testing / Jest & More
This course consists of two parts. In the first part of the course students will explore all the fundamentals with a progressive, example-driven approach. You’ll create your first apps, learn how to write components, start handling user interaction, and manage rich forms. We end the first part by exploring the inner workings of Create React App (Facebook’s tool for running React apps), writing automated unit tests, and building a multi-page app that uses client-side routing.
The latter part of the course moves into more advanced concepts that you’ll see used in large, production applications. These concepts explore strategies for data architecture, transport, and management:
- Redux is a state management paradigm based on Facecourse’s Flux architecture. Redux provides a structure for large state trees and allows you to decouple user interaction in your app from state changes.
- GraphQL is a powerful, typed, REST API alternative where the client describes the data it needs.
- Hooks is the powerful, new way to maintain state and properties with functional components and the future of React according to Facebook.
- Students will build Single Page Applications (SPA), create robust routing with error handling, and both class and functional reusable components.
- The lab project will also include the use of form validation.
- The Flux and Redux parts of the lab project will assist the student in understanding the use of advanced state in React.
- The lab project will importantly unit test the application using both Jest and Enzyme.
