#Troubleshooting

When faced with critical bugs or version mismatches in node packages, avoid forking repositories. Learn how to patch and override dependencies elegantly using pnpm.

That wall of red text in your console isn't random noise. Learn to read stack traces and find bugs in seconds, not hours.

Team member changed the schema, and now `supabase db push` fails? Learn how to fix migration history mismatches using `migration repair`.

Works locally, fails on deploy? Learn the difference between Node.js and Edge Runtime. Fix import errors and configure Import Maps correctly.

Built a chat app, but Realtime subscription is silent? Check the 'Replication' setting. Learn why Postgres WAL is key to Supabase Realtime.

Troubleshooting absolute path import configuration issues in TypeScript/JavaScript projects. Exploring the 'Map vs Taxi Driver' analogy, CommonJS vs ESM history, and Monorepo setup.

You changed the code, saved it, but the browser does nothing. Tired of hitting F5 a million times? We dive into how HMR (Hot Module Replacement) works, why it breaks (circular dependencies, case sensitivity, etc.), and how to fix it so you can regain your development speed.

You added the file to .gitignore, but Git keeps tracking it. Is Git broken? No, you just missed the golden rule. We explain Git's tracking logic using a 'Club Blacklist' analogy and show you how to evict unwanted files using `git rm --cached` without deleting your local data.

It's 3 AM. You essentially just handed your AWS keys to every bot on the internet. Panicking and deleting the file won't save you because Git remembers everything. We walk through the specific steps to scrub sensitive data from history using `git reset`, how to apologize gracefully with `git revert`, and how `git reflog` can save you when you accidentally delete your work.

Add one small feature and suddenly your DB CPU hits 100%. The culprit is usually the N+1 problem caused by ORM's Lazy Loading. Here's how to diagnose it, cut 1000 queries down to 1, and avoid the ORM mistakes that cause it.

Fix the 'async/await is not yet supported in Client Components' error in Next.js once and for all. This comprehensive guide explores the architectural differences between Server Components and Client Components, explains why React Hooks conflict with async rendering, and provides three robust strategies for data fetching: passing data from Server Components, using useEffect, and leveraging libraries like TanStack Query.
