Video: Leveraging the Event Loop for Blazing-Fast Applications!

This talk covers the event loop, microtask queue, and provides a live demo. JavaScript is single-threaded but can perform tasks that only a multithreaded environment can. The event loop consists of a call stack and microtask queue, which allow JavaScript to run non-blocking operations. Leveraging the microtask queue can lead to significant performance improvements in applications, such as React. However, it is important to use it correctly to avoid issues like infinite loops.

This talk has been presented at React Advanced 2023, check out the latest edition of this React Conference.

    Hey everyone, in my implementation I did a little mistake on stage, sorry for that. If you move the boolean at row 34 outside the callback (Row 33) at 18:27 you will effectively achieve the 100x performance improvement you were all waiting for! Sorry but the anxiety of the moment made me make a mistake there ;)

Kent C. Dodds discusses the concept of problem elimination rather than just problem-solving. He introduces the idea of a problem tree and the importance of avoiding creating solutions prematurely. Kent uses examples like Tesla's electric engine and Remix framework to illustrate the benefits of problem elimination. He emphasizes the value of trade-offs and taking the easier path, as well as the need to constantly re-evaluate and change approaches to eliminate problems.

Scaling Up with Remix and Micro Frontends
Top Content
This talk discusses the usage of Microfrontends in Remix and introduces the Tiny Frontend library. Kazoo, a used car buying platform, follows a domain-driven design approach and encountered issues with granular slicing. Tiny Frontend aims to solve the slicing problem and promotes type safety and compatibility of shared dependencies. The speaker demonstrates how Tiny Frontend works with server-side rendering and how Remix can consume and update components without redeploying the app. The talk also explores the usage of micro frontends and the future support for Webpack Module Federation in Remix.

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.

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.

Jotai Atoms Are Just Functions
Top Content
State management in React is a highly discussed topic with many libraries and solutions. Jotai is a new library based on atoms, which represent pieces of state. Atoms in Jotai are used to define state without holding values and can be used for global, semi-global, or local states. Jotai atoms are reusable definitions that are independent from React and can be used without React in an experimental library called Jotajsx.

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 🤐)

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.

Using a library might seem easy at first glance, but how do you choose the right library? How do you upgrade an existing one? And how do you wade through the documentation to find what you want?
In this workshop, we’ll discuss all these finer points while going through a general example of building a code editor using CodeMirror in React. All while sharing some of the nuances our team learned about using this library and some problems we encountered.
