tsconfig.json:

{ "compilerOptions": { "outDir": "./dist/" }, "references": [ { "path": "./demos/tsconfig.json" }, { "path": "./app/tsconfig.json" } ] } 

app/tsconfig.json:

{ "compilerOptions": { "composite": true, "outDir": "../app-dist/" }, "include": ["**/*"], "exclude": ["**/*-demos.*"] } 

app/Component-demos.ts:

// This errors. import * as helpers from 'demos/helpers'; export const demo = () => { helpers; }

demos/tsconfig.json:

{ "compilerOptions": { "composite": true, "rootDir": "../", "outDir": "../demos-dist/", "paths": { "demos/*": ["./*"] } }, "include": [ "**/*", "../app/**/*-demos.*" ], "references": [{ "path": "../app/tsconfig.json" }] } 

demos/helpers.ts:

export const foo = 1;

🙁 Actual behavior

When I run tsc --build --verbose tsconfig.json, there are no errors, but when I open my editor (VS Code) and open the file app/Component-demos.ts, I see errors:

🙂 Expected behavior

No errors inside my editor.

Additional information about the issue

When app/Component-demos.ts is opened, I believe TypeScript traverses parent file directories searching for a tsconfig.json file, and it stops at the first file it finds which in this case is app/tsconfig.json. This TS project does not include the file app/Component-demos.ts, so I believe TypeScript should continue traversing parent file directories to search for another tsconfig.json that does include the file. In this case, we want TypeScript to discover the root tsconfig.json.
