If you want to build a new app or a new website fully with React, we recommend picking one of the React-powered frameworks popular in the community.
如果你想完全用 React 构建一个新的应用或网站，我们建议选择社区中流行的、由 React 驱动的框架。
You can use React without a framework, however we’ve found that most apps and sites eventually build solutions to common problems such as code-splitting, routing, data fetching, and generating HTML. These problems are common to all UI libraries, not just React.
你可以在没有框架的情况下使用 React，但是我们发现大多数应用程序和网站最终都会构建常见问题的解决方案，例如代码分割、路由、数据获取和生成 HTML。不仅仅是 React，这些问题对于所有 UI 库都很常见。
By starting with a framework, you can get started with React quickly, and avoid essentially building your own framework later.
从框架开始一个项目，你就可以快速使用 React，这样以后也不需要构建自己的框架。
深入探讨
You can definitely use React without a framework—that’s how you’d use React for a part of your page. However, if you’re building a new app or a site fully with React, we recommend using a framework.
你当然可以在没有框架的情况下使用 React——这也就是你将 使用 React 作为页面的一部分。但是，如果你完全使用 React 构建新应用程序或网站，我们建议使用框架。
Here’s why.
原因如下。
Even if you don’t need routing or data fetching at first, you’ll likely want to add some libraries for them. As your JavaScript bundle grows with every new feature, you might have to figure out how to split code for every route individually. As your data fetching needs get more complex, you are likely to encounter server-client network waterfalls that make your app feel very slow. As your audience includes more users with poor network conditions and low-end devices, you might need to generate HTML from your components to display content early—either on the server, or during the build time. Changing your setup to run some of your code on the server or during the build can be very tricky.
即使你一开始不需要路由或数据获取，你也可能需要为它们添加一些库。随着 JavaScript 包随着每个新功能的增加而增长，你可能必须弄清楚如何单独拆分每个路由的代码。随着数据获取需求变得更加复杂，你可能会遇到服务器-客户端网络瀑布，这会让你的应用程序让人感觉非常缓慢。由于你的受众里面有更多网络条件较差和低端设备的用户，你可能需要从组件生成 HTML 以便尽早显示内容（无论是在服务器上还是在构建期间）。更改设定以在服务器上或构建期间运行某些代码可能非常棘手。
These problems are not React-specific. This is why Svelte has SvelteKit, Vue has Nuxt, and so on. To solve these problems on your own, you’ll need to integrate your bundler with your router and with your data fetching library. It’s not hard to get an initial setup working, but there are a lot of subtleties involved in making an app that loads quickly even as it grows over time. You’ll want to send down the minimal amount of app code but do so in a single client–server roundtrip, in parallel with any data required for the page. You’ll likely want the page to be interactive before your JavaScript code even runs, to support progressive enhancement. You may want to generate a folder of fully static HTML files for your marketing pages that can be hosted anywhere and still work with JavaScript disabled. Building these capabilities yourself takes real work.
这些问题不是 React 特有的。这就是为什么 Svelte 有 SvelteKit、Vue 有 Nuxt 等等。要自己解决这些问题，需要将打包工具与路由和数据获取的库集成。让初始设定正常工作并不难，但是要制作一个即使随着时间的推移而增长也能快速加载的应用程序，涉及到很多微妙之处。你需要发送最少量的应用程序代码，在单个客户端-服务器往返中执行此操作，与页面所需的任何数据并行。你可能希望页面在 JavaScript 代码运行之前就具有交互性，以支持渐进增强。你可能希望为你营销页面生成一个包含纯静态 HTML 文件的文件夹，该文件夹可以托管在任何地方，并且在禁用 JavaScript 的情况下仍然可以工作。自己构建这些东西需要付出实际的努力。
React frameworks on this page solve problems like these by default, with no extra work from your side. They let you start very lean and then scale your app with your needs. Each React framework has a community, so finding answers to questions and upgrading tooling is easier. Frameworks also give structure to your code, helping you and others retain context and skills between different projects. Conversely, with a custom setup it’s easier to get stuck on unsupported dependency versions, and you’ll essentially end up creating your own framework—albeit one with no community or upgrade path (and if it’s anything like the ones we’ve made in the past, more haphazardly designed).
此页面上的 React 框架默认解决此类问题，无需进行额外的工作。它们让你能够非常精简地开始，然后根据你的需求扩展应用程序。每个 React 框架都有一个社区，因此寻找问题的答案和升级工具变得更加容易。框架还为你的代码提供结构，帮助你和其他人保留不同项目之间的上下文和技巧。相反，使用自定义设置更容易陷入不受支持的依赖版本，并且你基本上最终会创建自己的框架——但这没有社区支持或升级路径（如果它和我们过去做的一样，设计得比较草率的话）。
If your app has unusual constraints not served well by these frameworks, or you prefer to solve these problems yourself, you can roll your own custom setup with React. Grab react and react-dom from npm, set up your custom build process with a bundler like Vite or Parcel, and add other tools as you need them for routing, static generation or server-side rendering, and more.
如果你的应用程序具有这些框架无法很好地满足的异常约束，或者你更喜欢自己解决这些问题，则可以使用 React 进行自己的自定义设置。从 npm 获取 react 和 react-dom，使用 Vite 或 Parcel 等打包工具设置自定义构建流程，并根据需要添加其他工具用于路由、静态内容生成或服务端渲染等。

Bleeding-edge React frameworks
As we’ve explored how to continue improving React, we realized that integrating React more closely with frameworks (specifically, with routing, bundling, and server technologies) is our biggest opportunity to help React users build better apps. The Next.js team has agreed to collaborate with us in researching, developing, integrating, and testing framework-agnostic bleeding-edge React features like React Server Components.
在我们探索如何继续改进 React 的过程中，我们意识到将 React 与框架（特别是路由、bundle 和服务端技术）更紧密地结合起来是我们帮助 React 用户构建更好的应用的最大机会。Next.js 团队已经同意与我们合作，研究、开发、集成和测试与框架无关的 React 前沿功能，如 React 服务器组件。
These features are getting closer to being production-ready every day, and we’ve been in talks with other bundler and framework developers about integrating them. Our hope is that in a year or two, all frameworks listed on this page will have full support for these features. (If you’re a framework author interested in partnering with us to experiment with these features, please let us know!)
这些功能每天都在接近生产就绪，而且我们一直在与其他 bundler 和框架的开发者讨论整合它们。我们希望在一两年内，这个页面上列出的所有框架都能完全支持这些功能。（如果你是一个框架的作者，有兴趣与我们合作来实验这些功能，请告诉我们！）
Next.js (App Router)
Next.js’s App Router is a redesign of the Next.js APIs aiming to fulfill the React team’s full-stack architecture vision. It lets you fetch data in asynchronous components that run on the server or even during the build.
Next.js 的 App Router 是对 Next.js API 的重新设计，旨在实现 React 团队的全栈架构愿景。它让你在异步组件中获取数据，这些组件甚至能在服务端构建过程中运行。
Next.js is maintained by Vercel. You can deploy a Next.js app to any Node.js or serverless hosting, or to your own server. Next.js also supports static export which doesn’t require a server.
Next.js 由 Vercel 维护。你可以将 Next.js 应用 部署到 Node.js 或 serverless 主机上，或部署到你自己的服务器上。Next.js 还支持 静态导出，不需要服务器。
深入探讨
Next.js’s App Router bundler fully implements the official React Server Components specification. This lets you mix build-time, server-only, and interactive components in a single React tree.
Next.js 的 App Router bundler 完全实现了官方的 React 服务器组件规范。这让你可以在一棵 React 树上同时使用 构建时、纯服务端 和 交互组件。
For example, you can write a server-only React component as an async function that reads from a database or from a file. Then you can pass data down from it to your interactive components:
例如，你可以把一个纯服务端的 React 组件写成一个 async 函数，从数据库或文件中读取。然后你可以把数据从它那里传递给你的交互组件：
// This component runs *only* on the server (or during the build).
// 这个组件只在服务端运行（或在构建期间）。
async function Talks({ confId }) {
// 1. You're on the server, so you can talk to your data layer. API endpoint not required.
// 1. 你在服务端，所以你可以和你的数据层对话。不需要 API 端点。
const talks = await db.Talks.findAll({ confId });
// 2. Add any amount of rendering logic. It won't make your JavaScript bundle larger.
// 2. 添加任意数量的渲染逻辑。它不会使你的 JavaScript bundle 变大。
const videos = talks.map(talk => talk.video);
// 3. Pass the data down to the components that will run in the browser.
// 3. 将数据向下传递给将在浏览器中运行的组件。
return <SearchableVideoList videos={videos} />;
}Next.js’s App Router also integrates data fetching with Suspense. This lets you specify a loading state (like a skeleton placeholder) for different parts of your user interface directly in your React tree:
Next.js 的 App Router 还集成了 用 Suspense 获取数据的能力。这让你可以直接在 React 树中为用户界面的不同部分指定一个加载状态（像一个骨架占位符）：
<Suspense fallback={<TalksLoading />}>
<Talks confId={conf.id} />
</Suspense>Server Components and Suspense are React features rather than Next.js features. However, adopting them at the framework level requires buy-in and non-trivial implementation work. At the moment, the Next.js App Router is the most complete implementation. The React team is working with bundler developers to make these features easier to implement in the next generation of frameworks.
服务器组件和 Suspense 是 React 的功能，不是由 Next.js 提供的。然而，在框架层面上采用它们需要投入大量的实现工作。目前，Next.js App Router 是最完整的实现。React 团队正在与 bundler 的开发人员合作，使这些功能在下一代框架中更容易实现。
