Frequently Asked Questions

What TypeScript features are supported in the generated code?

The generator creates TypeScript interfaces, types, and classes with full type safety. It supports optional properties, union types, nested interfaces, array types, and proper null handling. The generated code is compatible with the latest TypeScript standards.

How does the generator handle complex nested JSON structures?

Complex nested objects are converted to separate TypeScript interfaces with proper type relationships. Arrays are typed correctly, and the generator creates a hierarchy of types that matches your JSON structure while maintaining type safety.

Can I customize null and undefined handling in the generated types?

Yes, you can choose between different null handling strategies: optional properties with '?', union types with '| null', or ignoring null values entirely. This gives you flexibility in how strict you want your types to be.

Is the generated TypeScript code ready for production use?

Absolutely! The generated code follows TypeScript best practices, includes proper exports, and can be directly imported into your TypeScript projects. The interfaces are designed to be maintainable and follow standard naming conventions.
