How to Monitor a React (SPA) Application
Single Page Applications (SPAs) require special monitoring. Learn how to ensure your React app is serving the correct assets.
Monitoring the Frontend
React apps are often served as static files from a CDN (like Vercel or Netlify). Monitoring just the URL isn't enough if the underlying API is down.
1. Monitor the Static Assets
Ensure your index.html is being served correctly. Statzly can check if your main JS bundle is reachable.
2. Monitor the Backend API
This is critical. Your React app might load, but if the API returns a 500 error, the app is useless. Create a separate monitor in Statzly for your /api/health endpoint.
3. Keyword Verification
Check for the presence of your app's main container ID to ensure the React app has actually initialized.
