💻 Code

This is a snippet from the minimal repro repo I've created (https://github.com/TimUnderhay/ts-build-references-bug). The readme contains relevant code / reproduction details. This really can't be condensed into a snippet or playground link, as far as I can tell.

This is a reproduction of issue #44845. When using references within a monorepo to build an app that depends on a shared library reference, certain files get omitted from the tsc output for no evident reason.

The repo

Under projects/, there are two TS 'references', one a shared lib -- 'shared', and an app called 'server'. Server contains a reference to the shared lib, and also a path alias called :shared, pointing to the same place.

projects/server/tsconfig.json:

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "baseUrl": "./src",
    "rootDir": "..",
    "lib": ["ES2022"],
    "outDir": "./dist",
    "paths": {
      ":shared/*": [
        "../../shared/src/*"
      ]
    },
    "types": [
      "node"
    ]
  },
  "include": [
    "src/**/*.ts",
    "../shared/src/**/*.ts"
  ],
  "references": [
    {
      "path": "../shared"
    }
  ]
}

Steps to reproduce:

• From repo root, run npm install.
• cd projects/server
• npm run build (is just rm -rf dist/ && tsc --build -v)
• Check projects/server/dist/shared/src output. Notice that only the shared logging module was built. 'errors.ts' and 'global-type-overrides.ts' should be there based on the include pattern, but they aren't.

🙁 Actual behavior

Check projects/server/dist/shared/src output. Notice that only the shared logging module was built. 'errors.ts' and 'global-type-overrides.ts' should be there based on the include pattern, but they aren't.

🙂 Expected behavior

All modules derived from globs specified in include should be built.

Additional information about the issue

If one builds projects/shared on its own, all output files are present and accounted for in projects/shared/dist. The issue appears to be related to references. Building projects/server with eithertsc or tsc --build -v appear to yield the same end result -- missing files under projects/server/dist/shared.

It Gets Even Weirder

In projects/server/src/server.ts, if you uncomment the line // import { log } from ':shared/logging.js';, the entire shared subdir gets omitted from projects/server/dist!!

Just. Shouldn't. Happen.
