A TypeScript library and CLI (json2ts) that compiles JSON Schema definitions into TypeScript type declarations. It can be used programmatically via compile/compileFromFile or from the command line, with a browser-based live demo also available.

Use cases

• convert json schema to typescript interfaces
• generate typescript types from json schema files
• generate .d.ts declarations from api schemas
• batch convert a directory of json schemas to typescript
• generate typescript types from yaml schema files
• keep typescript types in sync with json schema

When to choose

• you maintain JSON Schema definitions and want matching TypeScript typings
• you want both a CLI and a programmatic API for schema-to-types conversion
• you need glob-based batch conversion of schema files
• you want style customization like single quotes or no semicolons in generated types

When to avoid

• you need to generate types from OpenAPI or GraphQL schemas rather than JSON Schema
• you need runtime validation, not just type declarations
• you work in a language other than TypeScript/JavaScript
