module - Typescript ReferenceError: exports is not defined

Question

Trying to implement a module following the official handbook, I get this error message:

Uncaught ReferenceError: exports is not defined

at app.js:2

But nowhere in my code do I ever use the name exports.

How can I fix this?

Few other Solutions for this issue

• Add the following line before other references to Javascript. This is a nice little hack.

   <script>var exports = {};</script>
