Description

React versions 16.8 and higher include React Hooks which solves several problems that went unaddressed in previous versions. React Hooks provide a direct API to React concepts you already know about, like props, state, context, refs and lifecycle events. This is not a beginner course on React itself; if you are not comfortable building simple React apps that use state, start out with the React: Getting Started course. In this course, Using React Hooks, you’ll learn both basic and advanced techniques for using React Hooks in React functional components where previously there was no good way to manage state or lifecycle events. First, you'll see how to use all of the built-in React Hooks provided by the React team. Next, you’ll discover that you can combine the base React Hooks into your own custom React Hooks. Finally, you’ll explore how to incorporate Hooks into a real-world React App. When you are finished with this course, you’ll confidently be able to combine functional components with React Hooks to build first class React apps.

Course Overview
Hi. I'm Peter Kellner, and welcome to my course, Using React Hooks. I'm a part‑time docs writer for Microsoft, part‑time author, part‑time conference organizer, and full‑time learner. React Hooks represents a huge step forward towards building a fully functional React app with minimal use of class components. Let me convince you that React Hooks, based off of functional components, are the best way to build React apps. Managing state and lifecycle events with Hooks is much easier, requires less code, and is much more readable than doing the same with React class components. Hooks are how JavaScript was always meant to be programmed. The major topics that we will cover include built‑in React Hooks, including useState, useRef, and useEffect, advanced Hooks like useReducer and useContext, we'll compare how React Hooks in functional components replace more complex code in class components, and finally, we'll build a real‑world React app using Hooks that includes a custom React Hook designed to handle CRUD operations running against a REST server. By the end of this course, you'll completely understand how to, using React Hooks, make your React functional components work with state and component lifecycle events in your apps. You'll be able to build an entire React app with just functional components and React Hooks, no class components needed. This is not a beginner course on React itself. If you are not comfortable building simple React apps that use state, I suggest you start out with the React: Getting Started or React Fundamentals course, and then take this one after. Join me and learn how you can use React Hooks in all your apps by watching this course, Using React Hooks, at Pluralsight.
