Deep Dive on React Hooks Architecture

The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components a better understanding of how each React hook can be used.You will learn all about the pros and cons of the various hooks. You will learn when to use useState() versus useReducer(). We will look at using useContext() efficiently. You will see when to use useLayoutEffect() and when useEffect() is better.

A lot has changed in the world of state management in React the last few years. Where Redux used to be the main library for this, the introduction of the React Context and Hook APIs has shaken things up. No longer do you need external libraries to handle both component and global state in your applications. In this workshop you'll learn the different approaches to state management in the post-Redux era of React, all based on Hooks! And as a bonus, we'll explore two upcoming state management libraries in the React ecosystem.

Learn how to handle forms in React using the latest features, such as startTransition, useTransition, useOptimistic, and useActionState, with and without React 19 server actions, alongside proper validation, error handling, and best practices.The workshop will begin by demonstrating traditional form handling using useState and useEffect for client-side rendering. Gradually, we'll transition to using the latest React 19 features, including server-side forms and the newest hooks for managing form states and errors. By the end of the workshop, participants will understand how to create robust forms with proper validation and error handling.Learning GoalsLatest React 19 Hooks — useTransition, useFormStatus, useOptimistic, useActionState, useDeferredValueServer ActionsRevalidationsServer-side ValidationError handlingSecurity practices
