# quicktype JSON Schema to Typed Code Generator

Generate strongly-typed models and serializers from JSON, JSON Schema, TypeScript, and GraphQL queries in 20+ programming languages. quicktype turns sample data into production-ready type definitions for Swift, C#, Go, Python, Rust, Java, Kotlin, and more.

## Installation

Use the upstream install or setup path that matches your environment:
- npm install -g quicktype
- $ npm install quicktype-core
- npm install
- npm install --ignore-scripts # Install dependencies

Requirements and caveats from upstream:
- | [Dart](https://app.quicktype.io/#l=dart) | [Python](https://app.quicktype.io/#l=python) | [C#](https://app.quicktype.io/#l=cs) | [Go](https://app.quicktype.io/#l=go) | [C++](https://app.quicktype.io/#l=cpp) |
- You can use quicktype as a JavaScript function within node or browsers. First add the quicktype-core package:
- const { lines: pythonPerson } = await quicktypeJSONSchema("python", "Person", jsonSchemaString);

Basic usage or getting-started notes:
- There are many ways to use quicktype. [app.quicktype.io](https://app.quicktype.io) is the most powerful and complete UI. The web app also works offline and doesn't send your sample data over the Internet, so paste away!
- For the best CLI, we recommend installing quicktype globally via npm:
- bash
