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.
