The library for web and native user interfaces
Create user interfaces from components
React lets you build user interfaces out of individual pieces called components. Create your own React components like, , and . 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
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.
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.
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
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.
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
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.
