# React wants to win you back… Source: https://www.youtube.com/watch?v=yl0YWA2K2B0 Recap page: https://rapidrecap.app/video/yl0YWA2K2B0 Generated: 2025-10-17T20:01:58.238+00:00 --- ## Quick Overview React is undergoing a major shift, moving its core technologies like React and React Native to an independent foundation, React Foundation, to ensure future stability, while simultaneously introducing new features like the React Compiler 1.0, the `useEffectEvent` hook to solve stale closure issues, the `` component for smart hiding/restoring UI state, and the Remix framework moving away from direct React dependencies. **Key Points:** - React and React Native are moving to a new, independent entity called the React Foundation to ensure long-term governance and stability. - React Compiler 1.0 is now available, which automatically handles memoization, eliminating the need for manual useMemo, useCallback, and React.memo. - The new `useEffectEvent` hook allows functions inside `useEffect` to access the latest state/props without needing to be declared in the dependency array, solving stale closure problems. - The `` component allows hiding and restoring the UI and internal state of children, acting as a 'smart display: none'. - The Remix framework is undergoing a major shift to version 3, building on Preact and abandoning critical dependencies, including React itself, to align closer to web standards. - The video references a previous Cloudflare outage caused by a bug in React's `useEffect` hook incorrectly handling an object in its dependency array, leading to infinite re-runs. ![Screenshot at 0:07: The video introduces the problem of developers overusing performance hooks like useMemo and useCallback, questioning if they are truly necessary performance fixes.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-00-07.png) **Context:** This video summarizes several major announcements and shifts occurring within the React ecosystem, apparently themed around a fictional 'React Conf 2025'. The content covers organizational changes (moving to a foundation), new API features (`useEffectEvent`, ``), improvements to performance tooling (React Compiler 1.0), and significant evolution in related frameworks like Remix, all presented through a blend of serious technical updates and meme-heavy commentary. ## Detailed Analysis The video details several key developments in the React ecosystem, starting with organizational restructuring: React and React Native are moving under the new, independent React Foundation to secure their future governance, ensuring they move away from being solely controlled by Meta. Technically, React Compiler 1.0 is released, which performs auto-optimization, removing the need for developers to manually use `useMemo`, `useCallback`, and `React.memo`. A new hook, `useEffectEvent`, is introduced to cleanly solve the problem of stale closures within `useEffect` by allowing the effect to be triggered by events without needing to list changing state/props in the dependency array. Another new component, ``, is shown, which efficiently hides/restores UI elements while preserving their internal state, superior to simply using `display: none`. Separately, the Remix framework announced Remix 3, which is shifting away from direct React dependency, forking Preact, and embracing web standards to build a new component model. The video also references past issues, like the Cloudflare outage caused by an incorrect object in a `useEffect` dependency array, contrasting that instability with the new tooling designed to prevent such errors. ### React Ecosystem Shift - React and React Native move to the independent React Foundation - Goal is to ensure the future of React - Foundation will have technical governance structure ### React 19.2 Features - React Compiler 1.0 is now available for auto-optimization - Eliminates need for manual useMemo, useCallback, and React.memo - New `useEffectEvent` hook solves stale closure issues in `useEffect` ### New APIs and Components - Introduction of the `` component for stateful hiding/restoring UI - `Activity` mode can be set to 'visible' or 'hidden' - Works better than CSS display: none by preserving internal state ### Remix Framework Evolution - Remix v2 is deprecated as they build Remix 3 - Remix 3 is a brand new framework built on a fork of Preact - Focus is on web standards and owning the full stack without critical dependencies, not even React ![Screenshot at 0:03: A Twitter post detailing massive $1M+ losses for over 200 traders on Hyperliquid due to over-leveraged positions, serving as an analogy for React developers facing unexpected errors.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-00-03.png) ![Screenshot at 0:09: A meme contrasting the pain of developers dealing with unnecessary performance hooks like useCallback/useMemo versus the promised fixes in new React features.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-00-09.png) ![Screenshot at 0:31: The title card for 'The Code Report' dated October 17th, 2025, indicating the satirical/future context of the announcements.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-00-31.png) ![Screenshot at 0:54: The official Cloudflare blog post detailing an outage caused by a bug in a React useEffect hook using a problematic object in its dependency array, leading to infinite API calls.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-00-54.png) ![Screenshot at 1:19: Code example showing the new useEffectEvent hook being imported and used to create an event handler function that can be called inside a standard useEffect without listing dependencies.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-01-19.png) ![Screenshot at 1:37: Documentation slide for the new \ component, which uses mode='visible' \| 'hidden' to hide/restore UI while maintaining component state.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-01-37.png) ![Screenshot at 2:14: Announcement slide for React Compiler 1.0, featuring dancing cats, signaling the release of the auto-optimization tool.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-02-14.png) ![Screenshot at 2:58: The announcement that Remix is moving to version 3, built by the same authors, signifying a major directional change for the framework.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-02-58.png) ![Screenshot at 3:35: A demonstration of Mobbin.com, the video sponsor, showcasing how detailed UI flow breakdowns can be copied directly into design tools like Figma.](https://ss.rapidrecap.app/screens/yl0YWA2K2B0/00-03-35.png)
