Trying to build my electron app with typescript generated from the electron-quick-start-typescript project. I have added an additional module called auth.ts which is not recognised when I start the app. I am trying to reference it in renderer.ts with

import { myfunction } from './auth'

However I can see that it is getting converted into js. What could be causing this issue? Why can't my application see my new module?

Additionally here is my package.json file if that helps.
