Next.js repairs

Fix Next.js build failures end to end.

Next.js combines TypeScript, bundling, static analysis, and framework rules. A single misconfigured env var or bad import can fail `next build` with a wall of errors.

App Router, server components, and monorepo packages interact. Fixing only the first error in the log often uncovers the next layer underneath.

Next.js failures are rarely one-file fixes

Symptoms we see often

  • `next build` fails during type checking or static generation
  • Missing NEXT_PUBLIC_* or server-only env at build time
  • Cannot find module for shared UI package in a monorepo
  • ESLint or TypeScript step fails in CI before deploy

Common causes

  • transpilePackages / experimental settings not listing project deps
  • Incorrect `outputFileTracing` or standalone output paths
  • Breaking changes after Next.js major upgrade
  • Mixed default and named exports across package boundaries

How RinaWarp fixes it

RinaWarp Terminal Pro follows the Observe → Plan → Approve → Execute → Proof workflow. Nothing executes without your approval.

  • Run the same build command CI uses (`next build`)
  • Repair tsconfig paths, package exports, and env templates
  • Apply code fixes for imports and component boundaries
  • Confirm build and critical tests pass before you merge

Before and after

Representative terminal output — your project will differ, but the verification pattern should look like this.

Before
next build
Error: Failed to collect page data for /dashboard
Error: Cannot find module '@acme/ui'
Build failed
After verification
Added project package to transpilePackages
Fixed package.json exports in @acme/ui
next build — completed
exit code 0
