React has been designed from the start for gradual adoption. You can use as little or as much React as you need. Whether you want to get a taste of React, add some interactivity to an HTML page, or start a complex React-powered app, this section will help you get started.

Try React

You don’t need to install anything to play with React. Try editing this sandbox!

function Greeting({ name }) {
  return <h1>Hello, {name}</h1>;

export default function App() {
  return <Greeting name="world" />

You can edit it directly or open it in a new tab by pressing the “Fork” button in the upper right corner.

Most pages in the React documentation contain sandboxes like this. Outside of the React documentation, there are many online sandboxes that support React: for example, CodeSandbox, StackBlitz, or CodePen.

Try React locally

To try React locally on your computer, download this HTML page. Open it in your editor and in your browser!

Add React to a page

If you’re working with an existing site and need to add a little bit of React, you can add React with a script tag.

Start a React project

If you’re ready to start a standalone project with React, you can set up a minimal toolchain for a pleasant developer experience. You can also start with a framework that makes a lot of decisions for you out of the box.
