JsonKeys

Transform a JSON file to a javascript object, where the keys are the same and each value is the order of the keys joined by a specified delimiter.

This package is very useful when using libraries like i18next or other javascript internationalization-framework to avoid the use of "magic strings".

Example

Input

{
  "HOME_PAGE": {
    "TITLE": "Hello world",
    "DESCRIPTION": "Lorem ipsum dolor sit amet, consectetur adipiscing elit",
    "NAVIGATION": {
      "HOME_PAGE": "Home Page",
      "ABOUT": "About"
    }
  }
}

Output

const JsonKeys = {
    "HOME_PAGE": {
        "TITLE": "HOME_PAGE.TITLE",
        "DESCRIPTION": "HOME_PAGE.DESCRIPTION",
        "NAVIGATION": {
            "HOME_PAGE": "HOME_PAGE.NAVIGATION.HOME_PAGE",
            "ABOUT": "HOME_PAGE.NAVIGATION.ABOUT"
        }
    }
};
export default JsonKeys;

How to

1. Installation

    "delimiter": "."
}

Key Meaning Default inputFile The Json input file required destinationFile Output object path jsonkeys.ts constantName What constant name will be exported in the destinationFile JsonKeys delimiter The delimiter that will be used to join the keys value .

      "json-keys": "jsonkeys -c jsonkeys.config.json -w"
  },
  // ...
}

  -V, --version        output the version number
