Build Error
Your app couldn't compile before deploying.
What is Build Error?
Before deploying, your code gets compiled into optimized files. If there's a TypeScript error, missing import, or syntax mistake — the build fails and deployment stops. Fix the error in the console output and try again.
Build errors are actually a good thing — they catch problems before your users see them. The error message almost always tells you exactly what file and line to fix.
In Vibe Coding
Build errors stop your deployment. Vercel, Railway, and Cloudflare all compile your code before deploying. If there's a TypeScript error or missing import, the build fails. Copy the error message and paste it into Cursor to fix it.
Example
For example: You push to GitHub and Vercel tries to build your app. It fails with: "Module not found: @/components/Header." You renamed the file to Navbar.tsx but forgot to update the import.
