Getting Started

Creating the client

Ideally, you should have only one instance of the client. Create one before rendering / initializing your application.

//with async/await
const auth0 = await createAuth0Client({
  domain: '<AUTH0_DOMAIN>',
  client_id: '<AUTH0_CLIENT_ID>'
});

//with promises
createAuth0Client({
  domain: '<AUTH0_DOMAIN>',
  client_id: '<AUTH0_CLIENT_ID>'
}).then(auth0 => {
  //...
});

1 - Login

<button id="login">Click to Login</button>

//with async/await
document.getElementById('login').addEventListener('click', async () => {
  await auth0.loginWithPopup();
  //logged in. you can get the user profile like this:
  const user = await auth0.getUser();
  console.log(user);
});

//with promises
document.getElementById('login').addEventListener('click', () => {
  auth0.loginWithPopup().then(token => {
    //logged in. you can get the user profile like this:
    auth0.getUser().then(user => {
      console.log(user);
    });
  });
});

2 - Calling an API

<button id="call-api">Call an API</button>

//with async/await
document.getElementById('call-api').addEventListener('click', async () => {
  const accessToken = await auth0.getTokenSilently();
  const result = await fetch('https://myapi.com', {
    method: 'GET',
    headers: {
      Authorization: `Bearer ${accessToken}`
    }
  });
  const data = await result.json();
  console.log(data);
});

//with promises
document.getElementById('call-api').addEventListener('click', () => {
  auth0
    .getTokenSilently()
    .then(accessToken =>
      fetch('https://myapi.com', {
        method: 'GET',
        headers: {
          Authorization: `Bearer ${accessToken}`
        }
      })
    )
    .then(result => result.json())
    .then(data => {
      console.log(data);
    });
});

3 - Logout

<button id="logout">Logout</button>

import createAuth0Client from '@auth0/auth0-spa-js';

document.getElementById('logout').addEventListener('click', () => {
  auth0.logout();
});

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

Why Auth0?
