Google Oauth identity provider quick start guide

auth-manager-routes.js

const loginClient = new LoginClient({
  // Both of these properties an be found and configured at:
  // https://authress.io/app/#/manage?focus=applications
  authenticationServiceUrl: 'https://login.application.com',
  applicationId: 'YOUR_APPLICATION_ID'
});

// This will redirect the user to Google, track their session with Authress,
// and then redirect back to your specified redirectUrl. By default we redirect them back
// to where they started, however usually you’ll want to specify the next location
// they should go.
await loginClient.authenticate({
  connectionId: 'SELECTED_CONNECTION_ID', redirectUrl: window.location.href
});

// Once the user returns to your site, you’ll want to get the necessary credentials.
// These should always be fetched by using the token getter:
const userToken = await loginClient.getToken();

// The full flow is
// 1. Check if the user is logged in on every page.
//     * If not redirect them to the login page, a route guard is the best way to handle.
//     * If there are credentials, get the token and the loop is complete
// 2. Ask the user to select connection/provider, call authenticate
// 3. Get the token from the SDK when you need it
//     * and pass it in the Authorization header in HTTP API requests.

const isUserLoggedIn = await loginClient.userSessionExists();
if (!isUserLoggedIn) {
  window.location.assign('/login');
} else {
  const userToken = await loginClient.getToken();
}

// If route === 'Login'
await loginClient.authenticate({
  connectionId: 'SELECTED_CONNECTION_ID', redirectUrl: window.location.href
});

// After redirect, same check, but now we'll have the token.
const isUserLoggedIn = await loginClient.userSessionExists();
if (!isUserLoggedIn) {
  window.location.assign('/login');
} else {
  const userToken = await loginClient.getToken();
