Video: React Server Components: Elevating Speed, Interactivity, and User Experience

From Author:

React Server Components offer an effective method for improving web app performance by rendering components on the server and streaming them to the client in real time. This session will cover the functionality and benefits of React Server Components, showing how they can increase application speed and responsiveness.

We will examine the role of asynchronous components, efficient data management, and the strategic use of modern React features to optimize load times and interactivity. With real-world examples and practical advice, you'll learn how to integrate these components to enhance your web app’s performance and provide a better user experience.

This talk has been presented at React Summit US 2024, check out the latest edition of this React Conference.

Video summary
My name is Aurora, a web developer from Norway. Today, I'll be teaching you how to elevate speed, interactivity, and user experience with React components. I'll be coding a project task manager and improving it using Next.js, Prisma, Azure SQL, and Tailwind CSS. We will review the code, starting with the important layout component. We will also learn how to improve navigation and data fetching, enhance visual stability and user experience, fix search functionality, and add category filters with loading states. Additionally, we will explore the use of React 19 hooks to enhance interactivity. Finally, we will optimize rendering and achieve improved Lighthouse scores for better performance. Overall, this Talk covers a range of techniques and tools to enhance React projects and deliver a better user experience.

FAQ

The initial load is slow because data fetches are intentionally slowed down and server components are rendered on the server before being shown.

The useOptimistic hook allows for instant state updates without network dependency, creating a more interactive experience for users.

Aurora uses suspense to unblock the page and render a fallback, allowing navigation while waiting for server components to stream in.

Aurora uses a progressive enhancement with an on-change handler and React 18 transitions to manage state and enable loading spinners during search.

Aurora focused on improving the first Contentful Paint, largest Contentful Paint, speed index, and maintaining a cumulative layout shift of zero.

Aurora faced challenges because a client component cannot be async, so she had to adjust the handling of promises and server data.

Aurora is speaking remotely at React Summit US about elevating speed, interactivity, and user experience with React components.

Aurora improved scores by incrementally showing content, managing suspense boundaries, and maintaining a low total blocking time with minimal JavaScript.

The app uses Next.js app router, Prisma as the ORM, an Azure SQL database, and Tailwind for CSS.

Aurora is a web developer from Norway who works as a consultant at Enmeta in Oslo.

React server components simplify server-side rendering and provide a mental model of components as pure functions. Using React as a library for server components allows for building a basic RSC server and connecting it to an SSR server. RSC responses are serialized virtual DOM that offload code from the client and handle interactivity. The client manifest maps serialized placeholders to real components on the client, enabling dynamic rendering. Server components combine the best of classic web development and progressive enhancement, offering the advantage of moving logic from the client to the server.

Mishko, the creator of Angular and AngularJS, discusses the challenges of website performance and JavaScript hydration. He explains the differences between client-side and server-side rendering and introduces Quik as a solution for efficient component hydration. Mishko demonstrates examples of state management and intercommunication using Quik. He highlights the performance benefits of using Quik with React and emphasizes the importance of reducing JavaScript size for better performance. Finally, he mentions the use of QUIC in both MPA and SPA applications for improved startup performance.

Routing in React 18 and Beyond
Top Content
Routing in React 18 brings a native app-like user experience and allows applications to transition between different environments. React Router and Next.js have different approaches to routing, with React Router using component-based routing and Next.js using file system-based routing. React server components provide the primitives to address the disadvantages of multipage applications while maintaining the same user experience. Improving navigation and routing in React involves including loading UI, pre-rendering parts of the screen, and using server components for more performant experiences. Next.js and Remix are moving towards a converging solution by combining component-based routing with file system routing.

React 18's concurrent rendering, specifically the useTransition hook, optimizes app performance by allowing non-urgent updates to be processed without freezing the UI. However, there are drawbacks such as longer processing time for non-urgent updates and increased CPU usage. The useTransition hook works similarly to throttling or bouncing, making it useful for addressing performance issues caused by multiple small components. Libraries like React Query may require the use of alternative APIs to handle urgent and non-urgent updates effectively.

This Talk introduces React Server Components (RSC) and explores their serialization process. It compares RSC to traditional server-side rendering (SSR) and explains how RSC handles promises and integrates client components. The Talk also discusses the RSC manifest and deserialization process. The speaker then introduces the Waku framework, which supports bundling, server, routing, and SSR. The future plans for Waku include integration with client state management libraries.

Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up).
Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too.
Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step.
(Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

Building instant-on web applications at scale have been elusive. Real-world sites need tracking, analytics, and complex user interfaces and interactions. We always start with the best intentions but end up with a less-than-ideal site.
QwikCity is a new meta-framework that allows you to build large-scale applications with constant startup-up performance. We will look at how to build a QwikCity application and what makes it unique. The workshop will show you how to set up a QwikCitp project. How routing works with layout. The demo application will fetch data and present it to the user in an editable form. And finally, how one can use authentication. All of the basic parts for any large-scale applications.
Along the way, we will also look at what makes Qwik unique, and how resumability enables constant startup performance no matter the application complexity.
