# @astrojs/react ⚛️

This **[Astro integration][astro-integration]** enables server-side rendering and client-side hydration for your [React](https://reactjs.org/) components.

## Installation

There are two ways to add integrations to your project. Let's try the most convenient option first!

### `astro add` command

Astro includes a CLI tool for adding first party integrations: `astro add`. This command will:
1. (Optionally) Install all necessary dependencies and peer dependencies
2. (Also optionally) Update your `astro.config.*` file to apply this integration

To install `@astrojs/react`, run the following from your project directory and follow the prompts:

```sh
# Using NPM
npx astro add react
# Using Yarn
yarn astro add react
# Using PNPM
pnpm astro add react
```

Finally, in the terminal window running Astro, press `CTRL+C` and then restart the dev server.

If you run into any issues, [feel free to report them to us on GitHub](https://github.com/withastro/astro/issues) and try the manual installation steps below.

### Install dependencies manually

First, install the `@astrojs/react` integration like so:

```sh
npm install @astrojs/react
```

Most package managers will install associated peer dependencies as well. Still, if you see a "Cannot find package 'react'" (or similar) warning when you start up Astro, you'll need to install `react` and `react-dom`:

```sh
npm install react react-dom
```

Now, apply this integration to your `astro.config.*` file using the `integrations` property:

__`astro.config.mjs`__

```js
import react from '@astrojs/react';

export default {
  // ...
  integrations: [react()],
}
```

## Getting started

To use your first React component in Astro, head to our [UI framework documentation][astro-ui-frameworks]. You'll explore:
- 📦 how framework components are loaded,
- 💧 client-side hydration options, and
- 🪆 opportunities to mix and nest frameworks together

Also check our [Astro Integration Documentation][astro-integration] for more on integrations.
