Your app works locally… but crashes after deployment? 😩
One of the most common mistakes I see is forgetting that local and production environments are different.
Before deploying, always check:
✅ Environment variables are correctly configured ✅ Production database credentials are set ✅ API URLs point to the right environment ✅ CORS settings allow your frontend ✅ Build errors are resolved ✅ Authentication works in production
My rule: Never assume that because it works on localhost, it's ready for production.
