How Airbnb Smoothly Upgrades React
IntroductionAirbnb’s frontend recently reached a major milestone: all of our web surfaces have been upgraded from React 16 to React 18, the current major version of React¹. This was a big project for a product with many surfaces, including Guest and Host pages as well as many internal tools. To safely perform this upgrade, we created the React Upgrade System: reusable infrastructure that allows us
State of React 2023
React has been around for 11 years, which seems hard to even grasp when you look at the current pace of web development. The reason why we're still talking about React today is that it's somehow been able to keep up, always evolving to meet the challenges thrown at it by its users. In fact, not content with merely keeping up, React is even leading the way on new innovative patterns such as Server
July 22, 2024 Release
For this summer release, we have been busy working on improving virtualization in many of our Spectrum components including TableView, ListView, and ListBox. We have significantly reduced the complexity of our implementation, resulting in smaller bundle size, better performance, and improved stability. In our testing, this resulted in 14x faster per-frame render times on large tables due to better
Understanding React Compiler | Tony Alicea
React's core architecture calls the functions you give it (i.e. your components) over and over. This fact both contributed to its popularity by simplifying its mental model, and created a point of possible performance issues. In general, if your functions do expensive things, then your app will be slow. Performance tuning, therefore, became a pain point for devs, as they had to manually tell React

[React 19] Disabling prerendering siblings of suspended components breaking common pattern · Issue #29898 · facebook/react
Summary I'm creating this issue to continue the discussion that spawned in the already merged PR (#26380) Several community members have raised concerns about this change and it has gained traction on both X and Reddit as well, I think it is important to prioritize this discussion as it can be a dealbreaker whether or not a project will upgrade to React 19 at all of this is not addressed. The prob

そのエフェクトは不要かも – React
エフェクトは React のパラダイムからの避難ハッチです。React の外に「踏み出して」、非 React ウィジェット、ネットワーク、またはブラウザ DOM などの外部システムと同期させることができるものです。外部システムが関与していない場合（例えば、props や state の変更に合わせてコンポーネントの state を更新したい場合）、エフェクトは必要ありません。不要なエフェクトを削除することで、コードが読みやすくなり、実行速度が向上し、エラーが発生しにくくなります。 このページで学ぶこと コンポーネントから不要なエフェクトを削除する理由と方法 エフェクトを使わずに高価な計算をキャッシュする方法 エフェクトを使わずにコンポーネントの state をリセットおよび調整する方法 イベントハンドラ間でロジックを共有する方法 イベントハンドラに移動すべきロジック 親コンポーネントに変更
