Sentry Integration for Supabase Edge Functions

Helpers Available

Module _shared/sentry.ts provides:

• initSentry() - Initialize (call once)
• handleError() - Capture errors automatically
• setSentryUser() - Track user (optional)
• addBreadcrumb() - Track flow (optional)

Usage

Basic Pattern

import { initSentry, handleError } from '../_shared/sentry.ts';

initSentry();

Deno.serve(async (req: Request) => {
  if (req.method === 'OPTIONS') {
    return new Response('ok', { headers: corsHeaders });
  }

  try {
    const result = await processData();
    return new Response(JSON.stringify({ success: true }));
  } catch (error) {
    return handleError(error, { functionName: 'my-function', corsHeaders });
  }
});

With User Context

import { initSentry, setSentryUser, handleError } from '../_shared/sentry.ts';
import { authenticate } from '../_shared/auth.ts';

initSentry();

Deno.serve(async (req: Request) => {
  try {
    const { user } = await authenticate(req);
    setSentryUser(user.id, user.email);
    
    // Your logic
    
    return new Response(JSON.stringify({ success: true }));
  } catch (error) {
    return handleError(error, { functionName: 'auth-function', corsHeaders });
  }
});

With Breadcrumbs

import { initSentry, addBreadcrumb, handleError } from '../_shared/sentry.ts';

initSentry();

try {
  addBreadcrumb('Started processing');
  const result = await process();
  addBreadcrumb('Completed', { count: result.length });
} catch (error) {
  return handleError(error, { functionName: 'processor', corsHeaders });
}

Setup

1. Set SENTRY_DSN in .env.local:

   SENTRY_DSN=https://your-sentry-dsn@sentry.io/123456

2. Module exists at supabase/functions/_shared/sentry.ts (already created)

What Gets Captured

✅ Error message and stack trace
✅ Function name (tagged)
✅ Request details
✅ User context (if set)
✅ Breadcrumbs (if added)
❌ Authorization headers (auto-removed)

Testing

throw new Error('Test error for Sentry');

Check Sentry dashboard for the error with full context.
