Code Examples

import H33 from '@h33/core'; import { useState } from 'react'; function LoginButton() { const [authenticated, setAuthenticated] = useState(false); const h33 = new H33(); const handleLogin = async () => { const result = await h33.authenticate({ email: 'user@example.com' }); setAuthenticated(result.success); }; return ( <button onClick={handleLogin}> {authenticated ? 'Logged In!' : 'Login with H33'} </button> ); }
import H33 from '@h33/core'; import express from 'express'; const app = express(); const h33 = new H33({ apiKey: process.env.H33_API_KEY }); // Middleware for passwordless auth app.use(async (req, res, next) => { const result = await h33.authenticate({ id: req.session.userId }); if (result.success) { req.user = result; next(); } else { res.status(401).send('Authentication failed'); } }); app.listen(3000);
import H33 from '@h33/core'; import auth0 from 'auth0-js'; // Your existing Auth0 setup const webAuth = new auth0.WebAuth({ domain: 'your-domain.auth0.com', clientID: 'your-client-id' }); // Add H33 in literally 2 lines const enhancedAuth0 = H33.enhance(webAuth); // Now your Auth0 users get passwordless authentication // No code changes needed, works with existing flows enhancedAuth0.login({ email: 'user@example.com' });
import H33 from '@h33/core'; import { H33StripeProcessor } from '@h33/stripe-integration'; const h33Stripe = new H33StripeProcessor({ stripeKey: process.env.STRIPE_SECRET_KEY, h33ApiKey: process.env.H33_API_KEY }); // Process payment with fraud prevention const result = await h33Stripe.processPayment({ amount: 2000, // $20.00 currency: 'usd', customer: { email: 'customer@example.com' }, paymentMethod: paymentMethodId }); if (result.success) { // Payment processed, fraud score: result.fraudScore console.log('Payment secure, fraud score:', result.fraudScore); } else { // Payment blocked for security console.log('Payment blocked:', result.reason); }
