Side notes

Help asked on Ember.js Discord to see if there was a better solution than declaring an empty ambiant module dummy/*:

  dfreeman: Unfortunately I don't have time to write up a full response on the issue you opened right now, but the short answer is that ts:precompile sets allowJs: false when it runs
  dfreeman: IMO (speaking only for myself and not any of the rest of the typed-ember folks) we shouldn't be setting allowJs: true in the default blueprint in the first place
  dfreeman: but I think that's the root of your problem
  dfreeman: either adding a .d.ts file alongside tests/dummy/app/app.js or actually converting that file to TS should solve your problem
  dfreeman: the declare module you suggested should also be fine
