+ React
+
+
+ The library for web and native user interfaces
+
+
+
+ Learn React
+
+
+ API Reference
+
+
+
+
+
+
+ Create user interfaces from components
+
+ React lets you build user interfaces out of individual pieces
+ called components. Create your own React components like{' '}
+ Thumbnail, LikeButton, and{' '}
+ Video. Then combine them into entire screens, pages,
+ and apps.
+
+
+
+
+
+
+
+ Whether you work on your own or with thousands of other
+ developers, using React feels the same. It is designed to let you
+ seamlessly combine components written by independent people,
+ teams, and organizations.
+
+
+
+
+
+
+ Write components with code and markup
+
+ React components are JavaScript functions. Want to show some
+ content conditionally? Use an if statement.
+ Displaying a list? Try array map(). Learning React is
+ learning programming.
+
+
+
+
+
+
+
+ This markup syntax is called JSX. It is a JavaScript syntax
+ extension popularized by React. Putting JSX markup close to
+ related rendering logic makes React components easy to create,
+ maintain, and delete.
+
+
+
+
+
+
+ Add interactivity wherever you need it
+
+ React components receive data and return what should appear on the
+ screen. You can pass them new data in response to an interaction,
+ like when the user types into an input. React will then update the
+ screen to match the new data.
+
+
+
+
+
+
+
+ You don’t have to build your whole page in React. Add React to
+ your existing HTML page, and render interactive React components
+ anywhere on it.
+
+
+
+ Add React to your page
+
+
+
+
+
+
+
+
+ Go full-stack
+ with a framework
+
+
+ React is a library. It lets you put components together, but it
+ doesn’t prescribe how to do routing and data fetching. To build an
+ entire app with React, we recommend a full-stack React framework
+ like Next.js or{' '}
+ Remix.
+
+
+
+
+
+
+
+ React is also an architecture. Frameworks that implement it let
+ you fetch data in asynchronous components that run on the server
+ or even during the build. Read data from a file or a database, and
+ pass it down to your interactive components.
+
+
+
+ Get started with a framework
+
+
+
+
+
+
+
+
Use the best from every platform
+
+ People love web and native apps for different reasons. React
+ lets you build both web apps and native apps using the same
+ skills. It leans upon each platform’s unique strengths to let
+ your interfaces feel just right on every platform.
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Stay true to the web
+
+
+ People expect web app pages to load fast. On the server,
+ React lets you start streaming HTML while you’re still
+ fetching data, progressively filling in the remaining
+ content before any JavaScript code loads. On the client,
+ React can use standard web APIs to keep your UI
+ responsive even in the middle of rendering.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Go truly native
+
+
+ People expect native apps to look and feel like their
+ platform.{' '}
+
+ React Native
+ {' '}
+ and{' '}
+ Expo{' '}
+ let you build apps in React for Android, iOS, and
+ more. They look and feel native because their UIs{' '}
+ are truly native. It’s not a web view—your
+ React components render real Android and iOS views
+ provided by the platform.
+
+
+
+
+
+
+
+
+ With React, you can be a web and a native developer. Your
+ team can ship to many platforms without sacrificing the user
+ experience. Your organization can bridge the platform silos, and
+ form teams that own entire features end-to-end.
+
+
+
+ Build for native platforms
+
+
+
+
+
+
+
+
+
+
Upgrade when the future is ready
+
+ React approaches changes with care. Every React commit is
+ tested on business-critical surfaces with over a billion
+ users. Over 100,000 React components at Meta help validate
+ every migration strategy.
+
+
+
+ The React team is always researching how to improve React.
+ Some research takes years to pay off. React has a high bar
+ for taking a research idea into production. Only proven
+ approaches become a part of React.

+ Join a community
+ of millions
+
+
+ You’re not alone. Two million developers from all over the
+ world visit the React docs every month. React is something
+ that people and teams can agree on.
+
+
+
+
+
+
+
+ This is why React is more than a library, an architecture, or
+ even an ecosystem. React is a community. It’s a place where
+ you can ask for help, find opportunities, and meet new
+ friends. You will meet both developers and designers,
+ beginners and experts, researchers and artists, teachers and
+ students. Our backgrounds may be very different, but React
+ lets us all create user interfaces together.
