Tracking issue for ESM migration

[scalvert]

Migration steps:

• [x] tsconfig.json

  • [x] compilerOptions.module should be set to node12 or nodenext (to enable top-level async/await)

• [x] package.json

  • [x] All packages need to have type set to module
  • [ ] All packages should declare a correct exports property
  • [ ] All dependencies should be updated to their esm variants (with some caveats)

• [x] ts files

  • [x] All relative imports should have file extensions (.js)
  • [x] all require statements should be removed in favor of import() or require via createRequire

Hi 👋

I'm just curious if there are any updates on this ESM migration and compatibility with ember-template-lint 4.0. Is there anything we can do to help out?

Thanks in advance.
