Cover image for 🚨 “It works on my
🚨 “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. What’s the funniest “works locally, breaks in production” bug you've faced? 👇

Cover image for 🚨 The API is returning
🚨 The API is returning 200… but your data is wrong? This can be harder to debug than a clear error. When I troubleshoot backend issues, I check: 🔍 Database queries 🔍 API request/response data 🔍 Authentication state 🔍 Backend logs 🔍 Frontend data handling A successful API response doesn't always mean the application is working correctly. Sometimes, the real bug is hiding in the data flow. Have you ever spent hours debugging a problem that turned out to be one small line of code? 😅

Cover image for Getting this error in Next.js?
Getting this error in Next.js? You’re not alone. Hydration failed because the initial UI does not match what was rendered on the server. This usually happens when your server-rendered HTML doesn't match what React renders in the browser. Common causes: • Using window or localStorage during server rendering • Rendering different content based on browser-only values • Incorrect date/time rendering • Invalid HTML nesting My first fix: Move browser-only logic into useEffect, or make the component client-side when necessary. 💡 Tip: Don't just hide the error. Find out why the server and client are rendering different UI. Have you encountered this error before? 👇
