Custom React Hooks Crash Course: Learn Hooks Through 6 Apps

Fast track to applying Custom React Hooks in your React apps using TypeScript

In this course, through 6 small applications, we'll recreate hooks and patterns that are commonly used in production web applications.

We'll learn how to encapsulate generic utility functions, fetches, business logic, or any code we want to reuse in Custom Hooks.

We'll use create-react-app as the starting port for every application, React 18 and TypeScript.

The lectures will cover:

1. Introduction to Custom Hooks (Counter app)

2. Structure of a Custom Hook (Toggle component)

3. Lifecycle in Custom Hooks (Weather dashboard)

4. Sharing Logic with Custom Hooks (useForm hook + localStorage)

5. Custom Hooks with Context API (Theme Switcher)

6. Advanced Patterns and Best Practices (Todo app)

7. Testing Custom Hooks (Counter app tests)

This course aims to show you different types of Custom React Hooks in various scenarios so you can learn, recognize, and apply these patterns to your application.

Working Through This Course

Every example app is built with Create React App. This was the easiest way for me to create React apps I can work with that don't have any unnecessary clutter, but these patterns can be applied in any React application, no matter how they are created.

This course is broken down into lectures and in each lecture you'll build a different app, and in some you'll even reuse some of the hooks you created earlier. The course is a practical, hands-on approach to learning through practice. You learn best when you code along with the examples.
