Monitoring Clerk User Onboarding Flow: Ensuring Growth Continuity

Clerk is the authentication standard for modern Next.js apps. If your onboarding breaks, your user growth stops immediately. This guide explains how to set up robust monitoring for your Clerk registration flow using supaguard and Playwright.

Growth Continuity Strategy

Onboarding is a delicate multi-step dance between your frontend and Clerk's service. If Clerk's social login buttons stop working, or if the email verification code isn't being accepted, your users will simply churn.

Quick Setup

Step 1: Use Clerk Testing Mode

1. Log in to your Clerk Dashboard.
2. In your Development environment, go to User Management → Test Users.
3. Use a Clerk-provided test email or configure a dedicated test account.
4. Set a fixed verification code (e.g., 000000) for this test user in Clerk's settings to bypass real email delivery.

Step 2: Create the Playwright Onboarding Script

Use this script to monitor your Clerk-powered signup and onboarding sequence.

import { test, expect } from '@playwright/test';

test('verify clerk signup and onboarding flow', async ({ page }) => {
  // 1. Go to the signup page
  await page.goto('https://your-app.com/signup');

  // 2. Fill in Clerk's Email Sign Up
  await page.fill('input[name="email"]', `tester-${Date.now()}@example.com`);
  await page.click('button[type="submit"]');

  // 3. Handle Clerk OTP Verification
  await page.waitForURL(/.*clerk\.com\/verify-email.*/);
  
  // Type fixed test code '000000'
  for (let i = 0; i < 6; i++) {
    await page.keyboard.type('0');
  }

  // 4. Wait for redirect to your app's onboarding screen
  await page.waitForURL('https://your-app.com/onboarding');

  // 5. Submit onboarding form
  await page.fill('input[name="company"]', 'SupaGuard Tester');
  await page.click('button#finish-onboarding');

  // 6. Verify landing in the main Dashboard
  await page.waitForURL('https://your-app.com/dashboard');
  await expect(page.locator('h1')).toContainText('Dashboard');
});

Step 3: Schedule with supaguard

1. Open your supaguard dashboard.
2. Paste the script into the Create Check wizard.
3. Select regions matching your user base (e.g., US, India, EU).
4. Set the frequency to every 10 or 15 minutes.
5. Save the check.

Best Practice: Monitoring Auth State

Don't just check if the page loads. Check if the auth cookie is correctly set.

Recommended Verifications

• Header Links: Check if the "Login" link has changed to "Profile".
• API Access: Verify that a post-login API call returns data instead of a 401.

The supaguard Solution
