If you define the types in TS, you can use https://github.com/YousefED/typescript-json-schema to automatically generate a JSON schema from it. That way, configurations can be specified either in an executable JS module or in a JSON file.

Yep, we’ll definitely use a tool like that. We already have types in Flow for all of Parcel 2, so should be possible to do something similar.
