Auth0 SDK for Single Page Applications using Authorization Code Grant Flow with PKCE
@auth0/auth0-spa-js is a JavaScript library designed to handle authentication in single-page applications (SPAs) using Auth0. It provides a simple and secure way to integrate Auth0's authentication and authorization services into your SPA.
Login
This feature allows users to log in to your application using Auth0. The code sample demonstrates how to create an Auth0 client and initiate a login redirect.
const auth0 = await createAuth0Client({
domain: 'YOUR_DOMAIN',
client_id: 'YOUR_CLIENT_ID'
});
await auth0.loginWithRedirect({
redirect_uri: window.location.origin
});
Logout
This feature allows users to log out of your application. The code sample shows how to log out and redirect the user to the home page.
await auth0.logout({
returnTo: window.location.origin
});
Get User Information
This feature retrieves the authenticated user's information. The code sample demonstrates how to get the user profile after authentication.
const user = await auth0.getUser();
console.log(user);
Token Handling
This feature handles token retrieval for authenticated requests. The code sample shows how to get an access token silently without redirecting the user.
const token = await auth0.getTokenSilently();
console.log(token);
oidc-client is a JavaScript library for OpenID Connect (OIDC) and OAuth2. It provides similar functionalities for handling authentication and authorization in SPAs. Compared to @auth0/auth0-spa-js, oidc-client is more generic and can be used with any OIDC-compliant identity provider.
Firebase Authentication provides backend services to help authenticate users in your application. It supports various authentication methods, including email/password, phone, and social providers. Unlike @auth0/auth0-spa-js, Firebase offers a broader range of services beyond authentication, such as database and hosting.

Create an Auth0Client
instance before rendering or initializing your application. You should only have one instance of the client.
//with async/await
const auth0 = await createAuth0Client({
domain: '<AUTH0_DOMAIN>',
client_id: '<AUTH0_CLIENT_ID>',
redirect_uri: '<MY_CALLBACK_URL>'
});
//with promises
createAuth0Client({
domain: '<AUTH0_DOMAIN>',
client_id: '<AUTH0_CLIENT_ID>',
redirect_uri: '<MY_CALLBACK_URL>'
}).then(auth0 => {
//...
});
<button id="login">Click to Login</button>
//with async/await
//redirect to the Universal Login Page
document.getElementById('login').addEventListener('click', async () => {
await auth0.loginWithRedirect();
});
//in your callback route (<MY_CALLBACK_URL>)
window.addEventListener('load', async () => {
const redirectResult = await auth0.handleRedirectCallback();
//logged in. you can get the user profile like this:
const user = await auth0.getUser();
console.log(user);
});
//with promises
//redirect to the Universal Login Page
document.getElementById('login').addEventListener('click', () => {
auth0.loginWithRedirect().catch(() => {
//error while redirecting the user
});
});
//in your callback route (<MY_CALLBACK_URL>)
window.addEventListener('load', () => {
auth0.handleRedirectCallback().then(redirectResult => {
//logged in. you can get the user profile like this:
auth0.getUser().then(user => {
console.log(user);
});
});
});
<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);
});
});
<button id="logout">Logout</button>
import createAuth0Client from '@auth0/auth0-spa-js';
document.getElementById('logout').addEventListener('click', () => {
auth0.logout();
});
