VS Code, typings - no IntelliSense

Question

I have a project with the following (shortened) structure.

.
├── app
│   ├── app.css
│   ├── app.js
│   └── home
│       ├── home.css
│       ├── home.html         


        

Answer 1

In the meantime (after hours of struggling) I came across my own solution.
Simply set the compiler option allowJs to true in tsconfig.json and save.

{
  "compilerOptions": {
    "target": "ES5",
    "module": "commonjs",
    "allowJs": true
  }
}

This is obviously a bug because it´s default is true according to the docs. I´ve posted this issue additionally on github.
