    }
}

Motivation

If you have a complex data structure, getting a good insight into the input and output of your RPCs won't be easy (It gets worse when you have an enormous payload). This tool helps you generate a JSON representation of the RPC request and response.

TODOs

• Enhance test coverage.
• Generate smarter and more specific random values.
• Support custom and predefined field value.
• Support Directory Tree style besides JSON.
