Until then the error message in index.ts:98 should be changed from:

      throw new Error("reference must start with #");

to

      throw new Error("external references (outside the json-schema file) are not supported");

I recently found this package and needed external networked references support. I whipped up this script really quick and it seems to do the job for me.

It uses json-schema-ref-parser to combine the references into one giant JSON object and then compiles the whole file.

@robertlong I was actually looking at using that package for json-schema-to-ts v2. Will give using it a shot - building ref resolution from scratch is hairier than it seems.
