Edge Functions — Analytics and Feedback

​

Analytics

Deno.serve(lerix.wrap(async (req) => {
  const { userId, amount } = await req.json();
  lerix.track('payment_succeeded', { amount, currency: 'OMR' }, { userId });
  return new Response('ok');
}));

• Events land in the same funnels and user counts as your apps’ events. userId is your own ID for the user, the same one your apps pass to setUser().
• Names start with a letter, then letters, digits, spaces, _, ., : or - (2 to 64 characters). Up to 25 properties, with string (up to 1,024 characters), finite number, boolean or null values. An invalid name drops the event; an invalid property is dropped on its own. track() never throws.

​

Delivery

lerix.track('nightly_sync_finished', { rows });
await lerix.flush();

​

Environment and opt-out

lerix.analytics.setEnabled(false); // stop recording and clear the buffer

​

Feedback

const id = await lerix.feedback.submit({
  message: 'Checkout button does nothing',
  email: 'user@example.com',          // optional
  labels: ['bug'],                    // project label keys
  userId,                             // optional, your ID for the user
  custom: { plan: 'pro' },            // optional, up to 50 keys / 16 KB
  attachments: [{ data: pngBytes }],  // optional, up to 5 PNG/JPEG/WebP images of 5 MB
});

• Attachments are uploaded first, then the feedback is created with their IDs.
• Failed requests are retried twice with the same client ID, so a retry never duplicates the feedback.
• submit() rejects with LerixApiException (INVALID_FEEDBACK for input that can’t be sent, or the API’s error) and resolves null with enabled: false.
• Inside a traced request, the feedback links to the trace.
