🚨 “It works on my machine.” The developer's most dangerous sentence 😂

Your app works perfectly locally, then suddenly breaks in production.

Before blaming the code, check:

🔹 Environment variables 🔹 Node.js versions 🔹 Database connection 🔹 API URLs 🔹 CORS configuration 🔹 Production build settings

Local success ≠ production readiness.

Always test your application in an environment as close to production as possible.

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.
