Unable to get Intellisense via JSDoc if referencing a type from other file

[Gelio]

• VSCode Version: 1.15.1
• OS Version: Windows 10 Pro 15063

foo.js:

export default class Foo {
  fooMethod() {
    console.log('Foo method called');
  }
}

bar.js:

/**
 * @param {Foo} foo 
 */
export default function bar(foo) {
  foo.
  // no Intellisense provided after the dot above
}

If I import Foo at the beginning of bar.js, like so:

import Foo from './foo';

then Intellisense works correctly. This is not ideal, though, as this import is not required for bar.js and eslint will often complain that Foo is not used.

Is there a way to get proper Intellisense without importing that module explicitly?

Yes, you currently need the import for intellisense to pick up the types properly.

We are discussing a better approach here: microsoft/TypeScript#14377 The proposal would allow you to reference types across files directly in jsdoc comments
