React Advanced

React Advanced Conference 2021

The workshop covers the new features of React 17 and React 18, including suspense, error handling, and concurrent mode. It emphasizes the importance of hands-on learning and typing code instead of just copying. The workshop explores using suspense and error boundaries to handle errors and improve the user experience. It also introduces new features in React 18, such as start transition and useTransition, to enhance responsiveness. The interaction between suspense and start transition is discussed, highlighting their collaboration in handling fallback UI and communication.

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.

This workshop explores suspense, lazy loading, bundle splitting, and data resources in React. It covers UI approaches to make applications appear faster and concurrent modes for more responsive applications. React.lazy is used to optimize loading and bundle size, while React Suspense is used to suspend rendering until components are loaded. Data resources can be created using the same principle as React.lazy. The workshop also discusses error handling, parallel suspense, and fetching data before rendering. Concurrent modes offer a solution to rendering delays and event handling in single-threaded JavaScript environments.

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 `&lt;Suspense /&gt;` 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 &lt;Suspense /&gt;, 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 &lt;SuspenseList /&gt; component. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Getting Started with Suspense and Concurrent Rendering in React

React Summit 2024

This Talk explores the suspense component in React and its benefits in handling fetched data. It delves into the rendering process of React components and how suspense anticipates requests. The offscreen fiber is introduced as a hidden component that ensures state continuity. The Talk also discusses the usage of suspense for handling concurrent queries and throwing promises, as well as the integration of Redux and the upcoming changes in React 19. Overall, the Talk provides insights into the workings of suspense and its potential applications in software development.

No more loaders, no more errors - Suspense has revolutionized the way developers handle asynchronous operations.But have you ever wondered what magic enables Suspense to work? How does Suspense know it has to display a fallback because a query is going to happen in a component below?In this talk, we’ll explore the inner workings of Suspense to uncover the magic that empowers one of the most beloved components of React.

The Suspense Quest - Inside React's Magic

Today's Talk is about using suspense and GraphQL with Apollo Client to create smooth user experiences. The Talk covers the introduction and power of suspense, the new Used Suspense Query hook in Apollo Client, updating components with suspense, using suspense boundaries and tradeoffs, optimizing playlist fetching with GraphQL, loading more tracks and using transitions, and concluding remarks and future developments.

For many app developers, GraphQL is instrumental in building great user experiences. With the introduction of React Suspense, developers have an ergonomic way to orchestrate loading states to improve upon the status quo.  In this talk, the Apollo Client team will show you how we built a non-trivial application using Apollo Client’s new Suspense features, GraphQL features like the @defer directive, and how to combine them to build great user experiences in your own apps.

This talk discusses the best practices for fetching data during the initial render of a component in React. It emphasizes the importance of fetching in advance and avoiding fetching twice. The talk also highlights the need for an external cache to store information about API calls and the use of a cleanup function to avoid memory leaks. Additionally, the speaker mentions their library, react-disposable-state, which can be used for making side effects during render.

What is suspense for data fetching in React? Why does React's model make creating network requests during render so difficult? Why does (to the presenter's knowledge) no library besides Relay support this, despite its sheer convenience?
 In this talk, Robert will discuss how React renders components (especially with regards to Suspense), and how to build a data-fetching library that functions correctly in light of those behaviors. Then, with all the pieces in place, we'll use a library, @boulton/react-disposable-state, to roll our own suspense-compatible data fetching!
