@kothatech/auth-js

A framework-agnostic client SDK for managing the complex PKCE authorization code flow natively in the browser.

npm install @kothatech/auth-js

Usage

Initiate login from your SPA:

import KothaAuth from '@kothatech/auth-js';

const auth = new KothaAuth({
  clientId: 'YOUR_CLIENT_ID',
  redirectUri: window.location.origin + '/callback',
  issuer: 'https://auth.kotha.im' // Or http://localhost:4000
});

// Redirects user to Kotha Auth login page
document.getElementById('login').onclick = () => auth.loginWithRedirect();

Handle the callback route (e.g. `/callback`):

// Automatically exchanges the code for a JWT token
try {
  const token = await auth.handleRedirectCallback();
  console.log('Logged in successfully', token);
} catch (err) {
  console.error('Login failed', err);
}
