Video Summary and Transcription
The video explores the concept of React Forget, a compiler developed by Meta to enhance client-side React development. React Forget aims to streamline performance by automatically handling memoization, reducing the need for developers to manually use useMemo or react.memo. The talk highlights how React Forget uses escape analysis and type inference to identify dependencies, thus improving application efficiency by avoiding unnecessary rerenders. The discussion touches on React Forget release date, noting that while no specific date is set, the goal is to release it as an open-source project once it meets Meta's quality standards. The video also delves into idiomatic React, emphasizing the potential of React Forget to optimize server builds and enable dead code elimination. With React Forget, developers can expect an ergonomic experience, as it aligns with the vision of making interactive parts of apps faster without compromising on code clarity.

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

FAQ

Yes, the long-term goal of React Forget is to eliminate the need for useMemo, react.memo, and useCallback by automatically handling memoization.

No, React Forget is not currently open-sourced. However, Meta plans to open-source it once it has been sufficiently refined and tested internally.

React Forget complements React server components by optimizing the client-side developer experience, making interactive parts of apps faster and improving overall performance.

There is no specific release date for React Forget. Meta is currently refining and testing it internally and plans to release it as an open-source project once it meets their high standards for quality and documentation.

Yes, React Forget will be part of the build pipeline and will require a small dependency and an additional runtime API in React. It will be available in a future stable version of React.

React Forget is a compiler developed by Meta that automatically memoizes your React components and hooks to improve performance by reducing unnecessary re-renders.

React Forget uses escape analysis and type inference to determine when to memoize components and hooks. It only memoizes values that make it out of the function and avoids memoizing primitives to prevent unnecessary re-renders.

The name 'React Forget' is part of Meta's policy to name projects with F-words that are puns. 'Remember' does not fit this naming convention.

React Forget improves performance by automatically determining when to memoize components and hooks, reducing unnecessary re-renders without the need for developers to manually add useMemo or react.memo.

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.

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 🤐)

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.
