Render + TypeScript: tsc runs but doesn't emit .js / .d.ts files

1

I’m deploying a monorepo (pnpm + turborepo) to Render. One of the workspace packages (@dx0/common) uses TypeScript and builds fine locally. But on Render, even though tsc runs with no errors, it only emits .d.ts.map and .tsbuildinfo—no .js or .d.ts.

This causes downstream packages (like @dx0/saas-server) to fail with TS2307: Cannot find module '@dx0/common/logging'.

Relevant details:

  • Node 22.14.0
  • TypeScript 5.3.3
  • "noEmit": false is explicitly set
  • No project references
  • Works locally with same config and build command

Build logs show tsc --listEmittedFiles running, but only .map files are emitted. No errors or warnings.

Has anyone seen this behavior? Is Render doing something that suppresses tsc output during build?
