It sounds like you've built an interesting tool for generating TypeScript interfaces from JSON samples! Your approach seems to focus on simplicity and ease-of-use, which can be very valuable in certain contexts where a lightweight solution is preferred over a more comprehensive but complex one.
Key Points of Your Tool
- Simplicity: The core functionality is straightforward—parse JSON inputs, generate TypeScript interfaces, and provide runtime type checks. This makes it easy to understand and use.
- Customizability: By focusing on generating basic types (primitives, arrays, objects), your tool can be easily extended or modified for specific needs without the overhead of a large codebase.
- Live Preview: The live-updating output pane is a nice touch that provides immediate feedback to users as they input JSON samples.
Potential Improvements
-
Error Handling and Validation:
- While you mentioned handling some edge cases, consider adding more robust error messages for invalid inputs (e.g., malformed JSON).
- Validate the generated TypeScript code against a TypeScript compiler API to ensure it's syntactically correct before displaying it in the output pane.
-
Additional Features:
- Support for optional fields and default values.
