JSON Schema generation? about typescript-is HOT 4 CLOSED

Inspired by this project, I wrote my own transformation plugin that actually generates JSON schema and passes it through AJV for validation. It doesn't emit separate json files but emits it into the javascript. One caveat is that right now each validation function has a full-blown copy of the schema needed. EG if you have validation functions for both interface Animal and interface Cat extends Animal, the Cat validator will contain duplicate JSON Schema code from Animal.

Anyway I'm not attesting to whether my project is any better or worse than this one. The reason I went this route was to make sure my own esoteric use cases are supported. Also by using ts-json-schema-generator it minimizes the code for traversing the the Typescript AST inside my own project.

Hi @mtiller

Indeed it's a nice way to generate JSON schema consistent with your TypeScript interfaces.
There are already some projects out there that can do this:

• https://github.com/YousefED/typescript-json-schema
• https://github.com/lbovet/typson
• https://github.com/vega/ts-json-schema-generator

Hope this helps :)
