React 18 introduces new APIs for rendering applications asynchronously on the server, enabling a simpler model for architecting and shipping user interfaces. When deployed on edge networking platforms like Cloudflare Workers, we can get dramatic performance and user experience improvements in our applications. In this talk, Sunil will demo and walk through this new model of writing React applications, with some insight into the implications for data fetching, styling, and overall direction of the React ecosystem.

1. Introduction and Personal Story

Short description:

I look forward to disappointing everybody here. It has been two years since I have been up on the stage. I've missed you all so much. I finished 500 days smoke-free. I quit smoking. This has been my GitHub avatar for the last 10 years. It doesn't really represent me anymore. A friend of mine did suggest a minor modification and I will be uploading it later today. This was actually made by Siddharth Kshetrapal. He's not here today because his visa got screwed. But I think that's a good modification. And that's my story so far.

I look forward to disappointing everybody here. It has been a while. It has been two years since I have been up on the stage. My name is Sunil Pai, I work at Cloudflare on the workers team. I used to be on the React team. They got rid of me pretty quickly.

And we have React stuff to talk about, but before I do that, I do want to start by saying I've missed you all so much. This is so weird. I met a bunch of people at the speaker's dinner yesterday. It's nice swapping stories, doing the same awkward hugs. There's the bro hug, there's the 200 hug, there's the fist bump, there's the weird elbow thing and I think it's time to retire that. But things have changed for me. As you can see, I get way better haircuts now. I dress a little nicer and especially for the occasion, shout out to Tom Dale. I hope I'm doing you proud. I've been eating better, exercising better, but the thing that I am most proud of and I'm sharing it with all my personal friends here is two days ago, I finished 500 days smoke-free. I quit smoking. Which is a good thing. So happy. I'm very proud of it. This is the thing that I've been telling everyone. It does leave me with one complication. This has been my GitHub avatar for the last 10 years. Ever since I've had one. It's cool. I used Photoshop back in the day when I had a pirated copy. But it doesn't really represent me anymore. But a friend of mine did suggest a minor modification and I will be uploading it later today. I think it's pretty good. This was actually made by Siddharth Kshetrapal. He's not here today because his visa got screwed. It sucks, but look forward to his talk. But I think that's a good modification. And that's my story so far. Cool.

2. Introduction to the Talk

Short description:

This talk is about the future of React and introduces some new APIs. It's in beta and will be improved over the next year. It's an important release that is often overlooked in favor of other features. It will have a significant impact on our future development.

Let's get to the talk. Three things you should know about the talk I'm doing right now. It's kind of boring. We'll be talking about a couple of APIs, but if all goes well, you probably won't have to use it. Things will just happen. And that's nice. That's kind of a nice thing about React. Like all the improvements are slightly incremental. Nobody has to do any massive rewrites. You can leave old code as it is. This talk is a beta talk. Much like the actual APIs and the fact that React 18 is on the horizon, but there's going to be about a year, two years of experimentation usually when these things come out. Much like that, this talk itself is also in beta. This is the first time that I've put it together, what we're talking about, and it also means that maybe over the next year, I'll be improving the talk. So if you spot any mistakes, sorry about that, but it will get better. But this talk itself is in beta. The talk is also about the future. I don't usually do API talks, I like talking about the work I've done, but this, I think, is exciting enough that it's part of the React release that no one is really noticing. Everyone is talking about the cool hotness, which is server components and concurrent and all that, but I feel like this actually is way more defining for all the things we're going to be doing in the future. So those are the three things.

A Guide to React Rendering Behavior
Top Content
React is a library for "rendering" UI from components, but many users find themselves confused about how React rendering actually works. What do terms like "rendering", "reconciliation", "Fibers", and "committing" actually mean? When do renders happen? How does Context affect rendering, and how do libraries like Redux cause updates? In this talk, we'll clear up the confusion and provide a solid foundation for understanding when, why, and how React renders. We'll look at: - What "rendering" actually is - How React queues renders and the standard rendering behavior - How keys and component types are used in rendering - Techniques for optimizing render performance - How context usage affects rendering behavior| - How external libraries tie into React rendering

Humans are natural problem solvers and we're good enough at it that we've survived over the centuries and become the dominant species of the planet. Because we're so good at it, we sometimes become problem seekers too–looking for problems we can solve. Those who most successfully accomplish their goals are the problem eliminators. Let's talk about the distinction between solving and eliminating problems with examples from inside and outside the coding world.

Can useEffect affect your codebase negatively? From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. In this talk, we'll demystify the useEffect hook and get a better understanding of when (and when not) to use it, as well as discover how declarative effects can make effect management more maintainable in even the most complex React apps.

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 🤐)

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.

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.

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn
