Monorepo
If your app lives inside a monorepo (for example managed by lerna), you should consider creating core package to handle configuration and model definition. All packages using models should then depend on the core package.
This is an example of lerna package structure
Dependencies#
Make sure that both episode-loader and stats-loader depend on the core. This would be packages/episode-loader/package.json
Requiring models#
This could be body of the packages/episode-loader/index.js
