NX monorepo with paths do not work out of box or with modifications

[kbrilla]

Example NX repository with 1 angular app and 1 non buildable non publishable lib

Provided repository have few commits with few configurations that all work on non GO typescript language server.

1. out of box with lib:

{
 "compileOnSave": false,
 "compilerOptions": {
   "rootDir": ".",
   "sourceMap": true,
   "declaration": false,
   "moduleResolution": "node",
   "emitDecoratorMetadata": true,
   "experimentalDecorators": true,
   "importHelpers": true,
   "target": "es2015",
   "module": "esnext",
   "lib": ["es2020", "dom"],
   "skipLibCheck": true,
   "skipDefaultLibCheck": true,
   "baseUrl": ".",
   "paths": {
     "@org-test/test-lib-a": ["libs/src/index.ts"]
   }
 },
 "exclude": ["node_modules", "tmp"]
}

2. no baseUrl

{
  "compileOnSave": false,
  "compilerOptions": {
    "rootDir": ".",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "module": "esnext",
    "lib": ["es2020", "dom"],
    "skipLibCheck": true,
    "skipDefaultLibCheck": true,
    "paths": {
      "@org-test/test-lib-a": ["./libs/src/index.ts"]
    }
  },
  "exclude": ["node_modules", "tmp"]
}

3. moduleResolution bundler

{
  "compileOnSave": false,
  "compilerOptions": {
    "rootDir": ".",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "bundler",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "module": "esnext",
    "lib": ["es2020", "dom"],
    "skipLibCheck": true,
    "skipDefaultLibCheck": true,
    "paths": {
      "@org-test/test-lib-a": ["./libs/src/index.ts"]
    }
  },
  "exclude": ["node_modules", "tmp"]
}

4. "moduleResolution": "bundler", + "module": "preserve",

{
  "compileOnSave": false,
  "compilerOptions": {
    "rootDir": ".",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "bundler",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "module": "preserve",
    "lib": ["es2020", "dom"],
    "skipLibCheck": true,
    "skipDefaultLibCheck": true,
    "paths": {
      "@org-test/test-lib-a": ["./libs/src/index.ts"]
    }
  },
  "exclude": ["node_modules", "tmp"]
}

All of above do not work on typescript-go but work on typescript.

If this is configuration problem please provide working configuration and reason why it won't work in ts-go

tested with @typescript/native-preview 7.0.0-dev.20250611.1

You need to override the "leaf" tsconfigs to use paths that are relative to those files (Ex: ../../libs..., ./src/...)

[kbrilla]

Not sure what changed, probably vscode extension version but it all started working without any changes even with config 1 so probably all good now? Checked on my work project and it also works flawlessly.

[jakebailey]

It's possible #1268 fixed this. It would be helpful if you could install an older version of the extension (right click on it in the extension menu) and see when it went from broken to working.

[jakebailey]

I didn't notice you had a repro, oops. I went back to a commit well before this issue was reported, and tsgo at that point did not seem to error on any of the tsconfigs in that repo. So, I'm not sure what issue you were seeing.

Was this exclusively an editor problem? If so, then probably this was fixed by #1078?

If I go waaaay back, before tsgo was even on npm in VS Code, then there were some import errors fixed by #851, but I don't think they are what you were reporting.

[jakebailey]

Actually, #851 is not "way back", it's just 3 weeks ago. So it could be any of these. In any case, it sounds like it's fixed.

You need to override the "leaf" tsconfigs to use paths that are relative to those files (Ex: ../../libs..., ./src/...)

@aovens-quantifi For reference, if you find any difference that would require this, please report it. These are bugs!
