Cover image for Your Supabase app is working…
Your Supabase app is working… but your database is still exposed? 🔐 One mistake I see developers make is setting up authentication and forgetting about Row Level Security (RLS). If you're using Supabase, don't just create your tables and move on. Make sure you: ✅ Enable RLS on your tables ✅ Create policies for who can read data ✅ Create policies for who can insert or update data ✅ Never expose sensitive service keys in the frontend ✅ Test your policies with different user accounts Authentication tells you who the user is. RLS helps control what they can access. Have you ever had an RLS policy block something that should have worked? 👇

Cover image for Your app works locally… but
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. What’s the most frustrating deployment error you've faced? 👇

Cover image for 🚨 Your database query works…
🚨 Your database query works… but it’s taking 3 seconds? Before rewriting the whole backend, check your database indexes. One missing index can turn a fast query into a slow one as your data grows. Optimize the query before optimizing everything else. ⚡ Have you checked your database indexes recently? 👇

Cover image for Found a bug that only
Found a bug that only happened in production. The code looked fine locally. The real problem? A missing environment variable. Lesson: Always check your production environment variables before rewriting working code. 😅 Have you ever spent hours debugging something that turned out to be a simple configuration issue?
