React 会议 2021 回顾
2021年12月17日 由 Jesslyn Tannady 和 Rick Hanlon
🌐 December 17, 2021 by Jesslyn Tannady and Rick Hanlon
上周我们举办了第六届 React 大会。在往年，我们曾利用 React 大会的舞台发布改变行业的公告，如 React Native 和 React Hooks。今年，我们分享了 React 的多平台愿景，从发布 React 18 开始，并逐步采用并发特性。
🌐 Last week we hosted our 6th React Conf. In previous years, we’ve used the React Conf stage to deliver industry changing announcements such as React Native and React Hooks. This year, we shared our multi-platform vision for React, starting with the release of React 18 and gradual adoption of concurrent features.
这是 React Conf 第一次在线举办，并且免费进行直播，翻译成 8 种不同的语言。来自世界各地的参与者加入了我们的会议 Discord 通道以及回放活动，以便在所有时区都能访问。共有超过 50,000 人注册，19 场演讲观看次数超过 60,000 次，两项活动中 Discord 的参与者共达 5,000 人。
🌐 This was the first time React Conf was hosted online, and it was streamed for free, translated to 8 different languages. Participants from all over the world joined our conference Discord and the replay event for accessibility in all timezones. Over 50,000 people registered, with over 60,000 views of 19 talks, and 5,000 participants in Discord across both events.
所有讲座都可以在线播放。
🌐 All the talks are available to stream online.
以下是舞台上分享内容的摘要：
🌐 Here’s a summary of what was shared on stage:
React 18 和并发特性
🌐 React 18 and concurrent features
在主题演讲中，我们分享了从 React 18 开始的 React 未来愿景。
🌐 In the keynote, we shared our vision for the future of React starting with React 18.
React 18 增加了期待已久的并发渲染器，并对 Suspense 进行了更新，而没有任何重大破坏性更改。应用可以升级到 React 18，并开始逐步采用并发特性，其所需的努力与任何其他主要版本相当。
🌐 React 18 adds the long-awaited concurrent renderer and updates to Suspense without any major breaking changes. Apps can upgrade to React 18 and begin gradually adopting concurrent features with the amount of effort on par with any other major release.
这意味着没有并发模式，只有并发特性。
在主题演讲中，我们还分享了我们对 Suspense、服务器组件、新的 React 工作组以及我们对 React Native 的长期多平台愿景的设想。
🌐 In the keynote, we also shared our vision for Suspense, Server Components, new React working groups, and our long-term many-platform vision for React Native.

面向应用开发者的 React 18
🌐 React 18 for Application Developers
在主题演讲中，我们还宣布 React 18 RC 现在可以试用。待进一步反馈后，这将是我们明年初发布为稳定版的 React 的确切版本。
🌐 In the keynote, we also announced that the React 18 RC is available to try now. Pending further feedback, this is the exact version of React that we will publish to stable early next year.
要尝试 React 18 RC，请升级你的依赖：
🌐 To try the React 18 RC, upgrade your dependencies:
npm install react@rc react-dom@rc并切换到新的 createRoot API：
🌐 and switch to the new createRoot API:
// before
const container = document.getElementById('root');
ReactDOM.render(<App />, container);
// after
const container = document.getElementById('root');
const root = ReactDOM.createRoot(container);
root.render(<App/>);有关升级到 React 18 的演示，请参见 Shruti Kapoor 的演讲：

使用 Suspense 的流式服务器渲染
🌐 Streaming Server Rendering with Suspense
React 18 还包括使用 Suspense 提高服务器端渲染性能的改进。
🌐 React 18 also includes improvements to server-side rendering performance using Suspense.
流式服务器渲染允许你在服务器上从 React 组件生成 HTML，并将该 HTML 流式传输给用户。在 React 18 中，你可以使用 Suspense 将你的应用拆分为更小的独立单元，这些单元可以彼此独立流式传输，而不会阻塞应用的其他部分。这意味着用户将更快看到你的内容，并能够更快开始与其交互。
🌐 Streaming server rendering lets you generate HTML from React components on the server, and stream that HTML to your users. In React 18, you can use Suspense to break down your app into smaller independent units which can be streamed independently of each other without blocking the rest of the app. This means users will see your content sooner and be able to start interacting with it much faster.

第一个 React 工作组
🌐 The first React working group
对于 React 18，我们创建了第一个工作组，与专家、开发者、库维护者和教育工作者组成的小组进行协作。我们共同努力制定逐步采用的策略，并完善诸如 useId、useSyncExternalStore 和 useInsertionEffect 等新 API。
🌐 For React 18, we created our first Working Group to collaborate with a panel of experts, developers, library maintainers, and educators. Together we worked to create our gradual adoption strategy and refine new APIs such as useId, useSyncExternalStore, and useInsertionEffect.
有关这项工作的概述，请参见 Aakansha’ Doshi 的演讲：

React 开发者工具
🌐 React Developer Tooling
为了支持此版本中的新功能，我们还宣布了新成立的 React 开发工具团队以及一个新的时间线分析器，以帮助开发者调试他们的 React 应用。
🌐 To support the new features in this release, we also announced the newly formed React DevTools team and a new Timeline Profiler to help developers debug their React apps.
