Embedded Login Integration (React)


In this quickstart, we will embed Frontegg login box to your React application.

The code in the sample below is available in our Frontegg Samples repository

⚑ Before you start: ⚑


Getting your Frontegg subdomain

Frontegg creates a unique subdomain and client id for every environment created on the account. In order to retrieve the clientId subdomain that will act as the baseUrl in the integration, navigate to your workspace 'Settings' menu, 'Domains' and copy the Frontegg domain and clientId.

You will need them for this guide.

STEP 1: Create a New React application


If you have an existing app, skip this step.

To create a new app, use the following script.
$ npm create vite@latest app-with-frontegg --template react
cd app-with-frontegg

STEP 2: Install Frontegg libraries

Run the following command to Install frontegg React.JS library.

npm install @frontegg/react react-router-dom
yarn add @frontegg/react [email protected]

STEP 3: Configuration

Wrap your root component with FronteggProvider.

import React from 'react';
import ReactDOM from 'react-dom'; // For react 17
// For react 18: import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css';

import { FronteggProvider } from '@frontegg/react';

const contextOptions = {
  baseUrl: 'https://[YOUR_SUBDOMAIN].frontegg.com',

const authOptions = {
 // keepSessionAlive: true // Uncomment this in order to maintain the session alive

// For react 18: 
// const root = ReactDOM.createRoot(document.getElementById('root'));
// root.render(
    <FronteggProvider contextOptions={contextOptions} hostedLoginBox={false} authOptions={authOptions}>
        <App />

STEP 4: Getting the user context

Frontegg exposes the user context and the authentication state via the useAuth hook which allows you to redirect non-authenticated users to the login page and to get the user's information.

import React from 'react';
import { useAuth } from '@frontegg/react'

function App() {
  const { user, isAuthenticated } = useAuth();

  return (
    <div className='App'>
      {isAuthenticated && (
          <img src={user.profilePictureUrl} alt={user.name} />

export default App;

Great, Frontegg is now integrated with your app!

Login and logout routes have been added to your app:

  • Signup screen is at http://localhost:3000/account/sign-up
  • Login screen is at http://localhost:3000/account/login

If you are already logged in, go to http://localhost:3000/account/logout and log out.

Give it a try now!

Open http://localhost:3000/account/sign-up and sign up with your first user.
