# Install PM2 globally

pm2 saveThe included deploy script pulls latest changes, builds in a temp directory, swaps atomically, and restarts PM2:
npm run deployserver {
listen 80;
server_name your-domain.com;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_cache_bypass $http_upgrade;
}
}Since Cloudflare handles SSL, you can use Cloudflare's Origin CA certificate or Full (Strict) mode.
After creating a site in the dashboard, add this to your website's <head>:
<script defer src="https://your-domain.com/t.js" data-site="YOUR_SITE_ID"></script>That's it. The script automatically tracks:
- Pageviews (including SPA navigation)
- Referrers and UTM parameters
- Screen dimensions
- Affiliate referrals (
?ref=affiliate-slug)
- Go to your site's Settings and add your Stripe Secret Key
- When creating Stripe Checkout Sessions in your app, pass the visitor tracking IDs:
const session = await stripe.checkout.sessions.create({
// ...your checkout config
metadata: {
ts_visitor_id: window.__ts.vid,
ts_session_id: window.__ts.sid(),
},
});Traffic Source polls Stripe every 60 seconds and automatically matches payments to visitor sessions — no webhook setup required.
- Go to your site's Affiliates page
- Create an affiliate with a name, slug, and commission rate
- Share their referral link:
https://your-site.com?ref=affiliate-slug - Affiliates can view their own public dashboard via a share link
When a visitor arrives via a referral link and later converts, the affiliate is automatically credited.
