Exploring the depths of JSON: Unraveling the secrets of reading dynamic object data

Currently, I am receiving a JSON file from another app and my goal is to parse it in order to extract the data contained within. The JSON includes user-defined dynamic data with changing key/value pairs, which has left me feeling uncertain about how to effectively process these variables for further use.

Below is an example of the JSON structure that I need to work with:

{
  "context": [
    {
      "one": "https://example.one.com"
    },
    {
      "two": "https://example.two.com"
    },
    {
      "three": "https://example.three.com"
    }
  ],
  "name": "Batman",
  "age": "30",
  "one:myField": {
    "two:myField2": "Hello"
  },
  "three:myField3": "Hello2"
}

While I can easily access static or well-defined data like name & age, my challenge lies in understanding how to retrieve user-defined/dynamic data from this JSON format where key/value pairs are not consistent and may not follow a specific order after the 'age' property.

I am currently exploring ways to extract all user-defined data from this JSON:

  "one:myField": {
    "two:myField2": "Hello"
  },
  "three:myField3": "Hello2"

Is there a straightforward method or library that can help achieve this task? I am building my application using Vuejs/Nuxtjs framework.

Answer №1

I believe the API you are currently utilizing may not be the most optimal choice. It would be beneficial to have constant object parameters that provide a consistent way to access information. If you encounter unknown parameters, consider parsing JSON into an object and iterating through it.

const object = { a: 1, b: 2, c: 3 };

for (const property in object) {
  console.log(`${property}: ${object[property]}`);
}

To achieve this, you can loop through the keys of an object using Object.keys().

Here is a demonstration :

const data = {
  "context": [
    {
      "one": "https://example.one.com"
    },
    {
      "two": "https://example.two.com"
    },
    {
      "three": "https://example.three.com"
    }
  ],
  "name": "Superman",
  "age": "35",
  "power:myField": {
    "strength:myField2": "Hi"
  },
  "hero:myField3": "Greetings"
};

Object.keys(data).forEach(key => {
    if (typeof data[key] === 'object') {
    Object.keys(data[key]).forEach(innerKey => {
        console.log(innerKey, data[key][innerKey])
    })
  } else {
     console.log(key, data[key])
  }
})

  }
})

By utilizing the powerful combination of Object.keys and a recursive function, you can seamlessly handle multiple nested objects in your code without the need for constant refactoring!

const jsonData = {
    context: [
        {
            one: "https://example.one.com",
        },
        {
            two: "https://example.two.com",
        },
        {
            three: "https://example.three.com",
        },
    ],
    name: "Batman",
    age: "30",
    "one:myField": {
        "two:myField2": "Hello",
        "one_nested:myField": {
            another_nested_key: "another_nested_value",
        },
    },
    "three:myField3": "Hello2",
};

recursive(jsonData);

function recursive(nestedKey) {
    if (typeof nestedKey !== "object") return;

    Object.keys(nestedKey).forEach((key) => {
        if (typeof nestedKey[key] === "object") {
            recursive(nestedKey[key]);
        } else {
            console.log(key, nestedKey[key]);

            // add your conditions here

            if (key === "name") {
                // bla bla bla
            }
        }
    });
}
