Quicktype – Beautiful types from JSON

Hey, this is really cool! Cross-language validation of data types is such a pain. This looks really well-done.

This could be useful as a build tool plugin to generate consistent typings for frontend and backend code. Of course, using this as a build-time codegen tool means you can&#x27;t add any custom annotations or methods etc., so it could be a bit restrictive for most use cases.<p>Nice work though!

The only problem I see with this is that it doesn&#x27;t have support for optional types. This is nice to be able to distinguish between null&#x2F;empty fields and defaults. But this is very nice work regardless and will be useful in.many people&#x27;s usecases.

Looks like a lot of work went into this, at first I didn&#x27;t understand where it would be valuable.<p>Then I clicked on the &quot;multiple&quot; tab, and I kinda get it. Throw a bunch of data at it and it will build your types.<p>I&#x27;ve just started using typescript so will give the vscode a go.
