JSON to TypeScript

Why JSON to TypeScript?

• Auto-generate type definitions from API responses, reducing manual writing effort
• Ensure frontend code stays consistent with backend data structures
• Leverage TypeScript type checking to catch potential issues at compile time
• Provide better IDE auto-completion and documentation hints

Output Style Description

• InterfaceInterface: Uses the interface keyword to define types, supports declaration merging and extension
• Type AliasType Alias: Uses the type keyword to define type aliases, more flexible, supports union and intersection types

Code Options Description

• Add exportAdd export: Adds the export keyword to each type declaration for easy module export
• readonly membersreadonly members: Marks interface properties as readonly, enforcing immutability
• Unions over enumUnions over enum: Enum fields use type X = "a"

Configuration Options

Customizable root type name, output style (interface/type), whether to add export keyword, whether to use readonly members, whether to use unions over enum. Powered by quicktype engine, nested objects auto-generate corresponding sub-types, arrays infer element types and generate unions, optional fields are auto-inferred by the engine.
