How to convert JSON object structure to dot notation?

Question

I\'ve got a variable I\'m storing that will dictate what fields to exclude from a query:

excludeFields = {
  Contact: {
    Address: 0,
    Phone: 0
  }
}
         


        

Answer 1

I use a function pretty much similar to the accepted answer

    function convertJsonToDot(obj, parent = [], keyValue = {}) {
      for (let key in obj) {
        let keyPath = [...parent, key];
        if (obj[key]!== null && typeof obj[key] === 'object') {
            Object.assign(keyValue, convertJsonToDot(obj[key], keyPath, keyValue));
        } else {
            keyValue[keyPath.join('.')] = obj[key];
        }
    }
    return keyValue;
}

Here, I do an additional check 'obj[key] !== null' because unfortunately null is also of type 'object'.

I actually wanted to add this a comment to the accepted answer but couldn't because of not enough reputation.
