Render Backend Awake or not

Render provide a trigger url

Backend Health Check Before Triggering Render URL

Instead of blindly calling the Trigger URL, first check if the backend is already awake by sending a lightweight HEAD or OPTIONS request to your backend’s health endpoint. If it’s down (fails to respond), only then call the Trigger URL.

Steps to Implement

1. Check if the backend is alive by sending a lightweight request (HEAD or OPTIONS) to an existing API route (/health, /status, or /).

2. Only if the backend is down, call the Trigger URL to wake it up.

3. Store the wake-up timestamp in localStorage or sessionStorage to reduce redundant calls.

Why This is the Best Approach?

✅ Prevents Unnecessary Requests → If the backend is already running, no need to call the Trigger URL.
✅ Works for Multiple Users → Even if a different user has woken up the backend, your check ensures you don’t trigger it again.
✅ Uses a Lightweight HEAD Request → Doesn't fetch full API response, making it fast.
