try quicktype

• Ok I found one solid framework to generate typescript interfaces, from JSON Object :
  • https://www.npmjs.com/package/quicktype/v/5.0.4#options : the --no-enums options forces to generate Array of strings instead of enums (and that is very good)
  • it can be used from code (not just cli) : https://github.com/glideapps/quicktype#calling-quicktype-from-javascript
  • quicktype is very powerful, :
  • it can generate JSON Schema from bare JSON
  • it can generate Typescript interfaces from JSON, and there we want to use the --no-enums option equivalent in code (not with CLI)
  • https://github.com/glideapps/quicktype#calling-quicktype-from-javascript
  • https://quicktype.io/

I need to try that one

ok, done with six.ts : i could successfully find how to configure the --no-enums option, the equivalent is inferEnums: false :

async function quicktypeJSON(targetLanguage: string, typeName: string, jsonString: any) {
    const jsonInput = jsonInputForTargetLanguage(targetLanguage);

    // We could add multiple samples for the same desired
    // type, or many sources for other types. Here we're
    // just making one type from one piece of sample JSON.
    await jsonInput.addSource({
        name: typeName,
        samples: [jsonString]
    });

    const inputData = new InputData();
    inputData.addInput(jsonInput);

    return await quicktype({
        inputData,
        lang: targetLanguage,
        outputFilename: `src/examples/.quicktype.generated/quicktype.generated.ts`,
        inferEnums: false // that's how to force gnerate Arrayof string instead of an enum
    });
}
