QA Mode

QA Mode enables debug logging in the browser console for custom events, making it easy to verify your integration during development and staging.

Enable via URL​

Add ?tlog_mode=qa to any URL in your browser:

https://your-app.com/dashboard?tlog_mode=qa

QA Mode persists across page loads for the rest of the browser session (stored in sessionStorage) and works in both development and production builds. To disable it:

https://your-app.com/dashboard?tlog_mode=qa_off

What You See in QA Mode​

When QA Mode is active, custom events fired with tracelog.event() are logged to the browser console with:

  • Event name
  • Metadata (if provided)

Example console output:

[TraceLog] Custom Event: purchase_completed
{
  name: "purchase_completed",
  metadata: { orderId: "ORD-789", total: 149.99, currency: "USD" }
}
info

QA Mode logs custom events only. Automatic events (page views, clicks, scrolls, errors, web vitals) are not logged to the console.

Verifying Your Setup​

  1. Open your app in the browser
  2. Add ?tlog_mode=qa to the URL
  3. Open DevTools → Console
  4. Trigger the actions you want to verify (add to cart, sign up, etc.)
  5. Confirm the expected events appear with the correct metadata

Then open your TraceLog dashboard → Analytics to confirm the same events appear server-side.

tip

Use QA Mode alongside the TraceLog troubleshooting guide to diagnose missing events before going to production.
