JSON to Smithy Class

Tool Introduction

The JSON to Smithy Class tool is a free online converter designed to help developers quickly transform complex JSON data structures into standardized Smithy model definitions. It greatly simplifies the API interface design and service modeling process, improving the efficiency and accuracy of data structure definitions. Whether for building new APIs or generating Smithy models for existing services, this tool provides powerful support to help you efficiently manage and define service interfaces.

Smithy Introduction

Smithy is a protocol-agnostic Interface Definition Language (IDL) used to describe web services. It allows developers to define service operations, data structures, errors, and protocols in a language-independent manner. Through Smithy, client and server-side code can be generated in multiple languages, ensuring API definition consistency, maintainability, and interoperability. This tool aims to help users quickly convert common JSON data structures into Smithy IDL, thereby better utilizing Smithy for API design and development.

How to Use

1. Paste the JSON data you need to convert into the left input box. Please ensure the JSON format is valid.
2. The tool will intelligently infer the corresponding Smithy shapes (structure, list, map, etc.) and their member types based on your input JSON data structure.
3. Click the "Convert" button to see the generated Smithy model definition in the right output area.

Input Parameter Format: The tool accepts standard JSON strings as input, typically a JSON object or a JSON array containing objects, to define complex data structures. For example: {"name": "test", "age": 30}.

Output Result Format: The output result is text content conforming to the Smithy IDL specification, including namespace, use declarations, and definitions of shapes such as structure and list.

Usage Example

Below is an example of converting a JSON object to a Smithy structure:

• Example Input Data:

  {
    "productId": "p123",
    "name": "Example Product",
    "price": 99.99,
    "tags": ["electronic", "gadget"],
    "details": {
      "weightKg": 0.5,
      "dimensionsCm": "10x5x2"
    }
  }

• Expected Output Result:

  namespace com.example
  
  structure Product {
      productId: String,
      name: String,
      price: Float,
      tags: ProductTags,
      details: ProductDetails
  }
  
  list ProductTags {
      member: String
  }
  
  structure ProductDetails {
      weightKg: Float,
      dimensionsCm: String
  }

• Specific Operation Demonstration:

  Paste the above "Example Input Data" into the tool's JSON input box, then click the "Convert" button. The output area on the right will immediately display the corresponding Smithy model definition.

Frequently Asked Questions

• Q: What input formats are supported? A: This tool currently only supports standard JSON strings as input. Please ensure your input JSON data is correctly formatted and valid.
• Q: What is the format of the output result? A: The output result is text content conforming to the Smithy IDL (Interface Definition Language) specification, which can be directly used in Smithy projects or as part of API documentation.
• Q: How does the tool handle JSON arrays and nested objects? A: The tool has intelligent recognition capabilities, converting JSON arrays into Smithy list shapes and nested JSON objects into independent Smithy structure shapes, with automatic referencing.
• Q: Does the generated Smithy model include all Smithy features, such as traits? A: Currently, the tool primarily focuses on data structure (shape) conversion. Traits like @required, @nullable, or more complex validation rules may require users to manually add or modify them on the generated basic model.

Notes

• Please ensure that the input JSON data format is valid and conforms to JSON specifications, otherwise, conversion may fail or result in anomalies.
• For complex JSON fields or those with multiple possible types, the tool may not be able to completely and accurately infer the best Smithy type. It is recommended to carefully review and optimize the Smithy model after generation to meet actual API design requirements.
• This tool primarily provides basic structure conversion. For advanced features specific to Smithy (such as traits, Union types, Enum types, etc.), you may need to manually supplement and adjust the conversion results.
• To protect your data privacy, please avoid entering any sensitive or confidential information into this tool.
