Quicktype is a multi-language model generation engine that converts JSON and GraphQL schemas into type-safe models and serialization code. It functions as a JSON to type generator and a GraphQL type generator, producing strongly typed classes and interfaces across a wide array of target programming languages.
The system derives formal schemas from sample data and transforms these definitions into native language objects. This enables the synchronization of shared data models across diverse tech stacks and the development of type-safe interfaces for consuming external APIs.
The engine utilizes a transformation pipeline that maps source schemas to an intermediate representation before applying pluggable language renderers. This architecture supports custom output language definitions and provides a programmatic API for automating type conversion within build or deployment pipelines.
