VSCode TypeScript Default Import Renamed Can't Debug Watch Inspect

Code

filea.ts

const a: string = "hello";
export default a;

fileb.ts

import a from "./filea"
console.log(a);

tsconfig.json

{
   "compilerOptions": {
      "lib": [ "es6" ],
      "moduleResolution": "node",
      "module": "commonjs",
      "target": "es6",
      "sourceMap": true
   }
}

Expected behavior:

Works correctly in runtime
Variable a (imported one) can be inspected

Actual behavior:

Works correctly in runtime
Variable a (imported one) can't be inspected neither watched as VS Code says: not available

The problem is the variable a does not exist at runtime as the import is transpiled as:

const filea_1 = require("./filea");
console.log(filea_1.default);

Watching of filea_1.default works correctly, of course.

I am not sure if there is additional mapping somewhere, but everything else works well (breakpoints, other variable inspections...)

maybe the default imports can be transpiled as

const a = require("./filea").default;
console.log(a);

Commencez par filea.ts, fileb.ts et tsconfig.json, puis examinez le JavaScript CommonJS émis et sa source map tout en reproduisant le comportement de watch dans VS Code. Déterminez si les noms des imports par défaut peuvent être mappés vers l’accès filea_1.default dans le fichier généré sans altérer la sortie d’exécution existante. C’est terminé lorsque la variable importée a peut être inspectée et surveillée dans l’environnement NodeJS.
