Cursor build rescue

Cursor build output breaks on the production server

Cursor may use local-only dependencies or different build settings that produce output incompatible with production servers.

What is probably broken

The build passes locally but the production server cannot serve the output or it renders blank pages.

What production should look like

A clean production build that the server can serve correctly with all pages rendering.

STEP 01

Compare local and production build output

Find what differs between the local build and the server build.

  • Check the build output directory structure on both environments.
  • Compare the build logs for warnings or errors.
  • Verify the output directory matches what the server expects.

STEP 02

Fix the build configuration

Align the build settings between local and production.

  • Ensure the same Node version and package manager on both sides.
  • Check for local-only dependencies that are not in package.json.
  • Set the correct output directory in the server config.

STEP 03

Rebuild and deploy

Run a clean production build and verify the output.

  • Clear any cached build artifacts on the server.
  • Run a fresh build with production env vars.
  • Verify all pages and API routes respond correctly.
