Best Practices and Advanced TypeScript Tips for React Developers
Workshop
Are you a React developer trying to get the most benefits from TypeScript? Then this is the workshop for you.
In this interactive workshop, we will start at the basics and examine the pros and cons of different ways you can declare React components using TypeScript. After that we will move to more advanced concepts where we will go beyond the strict setting of TypeScript. You will learn when to use types like any, unknown and never. We will explore the use of type predicates, guards and exhaustive checking. You will learn about the built-in mapped types as well as how to create your own new type map utilities. And we will start programming in the TypeScript type system using conditional types and type inferring.

Concurrent Rendering Adventures in React 18
Featured WorkshopFree
With the release of React 18 we finally get the long awaited concurrent rendering. But how is that going to affect your application? What are the benefits of concurrent rendering in React? What do you need to do to switch to concurrent rendering when you upgrade to React 18? And what if you don’t want or can’t use concurrent rendering yet?

There are some behavior changes you need to be aware of! In this workshop we will cover all of those subjects and more.

Join me with your laptop in this interactive workshop. You will see how easy it is to switch to concurrent rendering in your React application. You will learn all about concurrent rendering, SuspenseList, the startTransition API and more.

Getting Started with Suspense and Concurrent Rendering in React
Featured Workshop
React keeps on evolving and making hard things easier for the average developer.
One case, where React was not particularly hard but very repetitive, is working with AJAX request. There is always the trinity of loading, success and possible error states that had to be handled each time. But no more as the `<Suspense />` component makes life much easier.
Another case is performance of larger and complex applications. Usually React is fast enough but with a large application rendering components can conflict with user interactions. Concurrent rendering will, mostly automatically, take care of this.
You will learn all about using <Suspense />, showing loading indicators and handling errors. You will see how easy it is to get started with concurrent rendering. You will make suspense even more capable combining it with concurrent rendering, the `useTransition()` hook and the <SuspenseList /> component.

React Hooks Tips Only the Pros Know
Featured Workshop
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.
