## Getting started
### Installation
Using [npm](https://npmjs.org/)
```bash
npm install @auth0/auth0-react
```
Using [yarn](https://yarnpkg.com/)
```bash
yarn add @auth0/auth0-react
```
### Configure Auth0
Create a **Single Page Application** in the [Auth0 Dashboard](https://manage.auth0.com/#/applications).
> **If you're using an existing application**, verify that you have configured the following settings in your Single Page Application:
>
> - Click on the "Settings" tab of your application's page.
> - Scroll down and click on the "Show Advanced Settings" link.
> - Under "Advanced Settings", click on the "OAuth" tab.
> - Ensure that "JsonWebToken Signature Algorithm" is set to `RS256` and that "OIDC Conformant" is enabled.
Next, configure the following URLs for your application under the "Application URIs" section of the "Settings" page:
- **Allowed Callback URLs**: `http://localhost:3000`
- **Allowed Logout URLs**: `http://localhost:3000`
- **Allowed Web Origins**: `http://localhost:3000`
> These URLs should reflect the origins that your application is running on. **Allowed Callback URLs** may also include a path, depending on where you're handling the callback.
Take note of the **Client ID** and **Domain** values under the "Basic Information" section. You'll need these values in the next step.
### Configure the SDK
Configure the SDK by wrapping your application in `Auth0Provider`:
```jsx
// src/index.js
import React from 'react';
import { createRoot } from 'react-dom/client';
import { Auth0Provider } from '@auth0/auth0-react';
import App from './App';
const root = createRoot(document.getElementById('app'));
root.render(
);
```
Instructions for React <18
```jsx
// src/index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { Auth0Provider } from '@auth0/auth0-react';
import App from './App';
ReactDOM.render(
,
document.getElementById('app')
);
```
Use the `useAuth0` hook in your components to access authentication state (`isLoading`, `isAuthenticated` and `user`) and authentication methods (`loginWithRedirect` and `logout`):
```jsx
// src/App.js
import React from 'react';
import { useAuth0 } from '@auth0/auth0-react';
function App() {
const { isLoading, isAuthenticated, error, user, loginWithRedirect, logout } =
useAuth0();
if (isLoading) {
return
Loading...
;
}
if (error) {
return
Oops... {error.message}
;
}
if (isAuthenticated) {
return (
Hello {user.name}{' '}
);
} else {
return ;
}
}
export default App;
```
