Installation

Using npm

npm install @auth0/auth0-react

Using yarn

yarn add @auth0/auth0-react

Getting Started

Configure the SDK by wrapping your application in Auth0Provider:

// src/index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { Auth0Provider } from '@auth0/auth0-react';
import App from './App';

ReactDOM.render(
  <Auth0Provider
    domain="YOUR_AUTH0_DOMAIN"
    clientId="YOUR_AUTH0_CLIENT_ID"
    redirectUri={window.location.origin}
  >
    <App />
  </Auth0Provider>,
  document.getElementById('app')
);

Use the useAuth0 hook in your components to access authentication state (isLoading, isAuthenticated and user) and authentication methods (loginWithRedirect and logout):

// 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 <div>Loading...</div>;
  }
  if (error) {
    return <div>Oops... {error.message}</div>;
  }

  if (isAuthenticated) {
    return (
      <div>
        Hello {user.name}{' '}
        <button onClick={() => logout({ returnTo: window.location.origin })}>
          Log out
        </button>
      </div>
    );
  } else {
    return <button onClick={loginWithRedirect}>Log in</button>;
  }
}

export default App;

Use with a Class Component

Use the withAuth0 higher order component to add the auth0 property to Class components:

import React, { Component } from 'react';
import { withAuth0 } from '@auth0/auth0-react';

class Profile extends Component {
  render() {
    // `this.props.auth0` has all the same properties as the `useAuth0` hook
    const { user } = this.props.auth0;
    return <div>Hello {user.name}</div>;
  }
}

export default withAuth0(Profile);

Protect a Route

Protect a route component using the withAuthenticationRequired higher order component. Visits to this route when unauthenticated will redirect the user to the login page and back to this page after login:

import React from 'react';
import { withAuthenticationRequired } from '@auth0/auth0-react';

const PrivateRoute = () => <div>Private</div>;

export default withAuthenticationRequired(PrivateRoute, {
  // Show a message while the user waits to be redirected to the login page.
  onRedirecting: () => <div>Redirecting you to the login page...</div>,
});

Note If you are using a custom router, you will need to supply the Auth0Provider with a custom onRedirectCallback method to perform the action that returns the user to the protected page. See examples for react-router, Gatsby and Next.js.

Call an API

Call a protected API with an Access Token:

import React, { useEffect, useState } from 'react';
import { useAuth0 } from '@auth0/auth0-react';

const Posts = () => {
  const { getAccessTokenSilently } = useAuth0();
  const [posts, setPosts] = useState(null);

  useEffect(() => {
    (async () => {
      try {
        const token = await getAccessTokenSilently({
          audience: 'https://api.example.com/',
          scope: 'read:posts',
        });
        const response = await fetch('https://api.example.com/posts', {
          headers: {
            Authorization: `Bearer ${token}`,
          },
        });
        setPosts(await response.json());
      } catch (e) {
        console.error(e);
      }
    })();
  }, [getAccessTokenSilently]);

  if (!posts) {
    return <div>Loading...</div>;
  }

  return (
    <ul>
      {posts.map((post, index) => {
        return <li key={index}>{post}</li>;
      })}
    </ul>
  );
};

export default Posts;

What is Auth0?

Auth0 helps you to easily:

  • Implement authentication with multiple identity providers, including social (e.g., Google, Facebook, Microsoft, LinkedIn, GitHub, Twitter, etc), or enterprise (e.g., Windows Azure AD, Google Apps, Active Directory, ADFS, SAML, etc.)
  • Log in users with username/password databases, passwordless, or multi-factor authentication
  • Link multiple user accounts together
  • Generate signed JSON Web Tokens to authorize your API calls and flow the user identity securely
  • Access demographics and analytics detailing how, when, and where users are logging in
  • Enrich user profiles from other data sources using customizable JavaScript rules
