In this course, you will learn how to use React Hooks, which will help you achieve better code composition, code reuse, and unit testing ability as opposed to using class components.

You’ll start by reviewing what React Hooks are all about and why we need them. This will set the stage for the rest of the course. After that you will dive into the Hooks API, how to manage application state globally, as well as how to create custom hooks.

In the second half, you’ll get into unit testing and how to work with the popular useDependency Pattern. By the end of this course, you’ll have the confidence to write enterprise-level React Hooks code.

A Deep Dive into React Hooks



There are many situations for developers while working on  React projects where it was required  to share the same state in a number of React components. React documentation provides insights into the concept of “lifting state up.” There are benefits and drawbacks to this approach. It works well within one feature but when sharing state between multiple features, it can quickly become messy with a number of props being passed around. Secondly, it becomes difficult to debug the code if issues arise. This is where it makes sense to define a global state so that various features can access the same data at any given time.





In this chapter, a global state management pattern with React Hooks will be discussed.
