Managing a JSON Array of Attributes for Display in ReactJS

When fetching data from an API, developers often encounter JSON structures that can be complex and sometimes confusing to work with. One such scenario arises when an API returns a JSON object with an array of attributes that contain similar naming conventions across different objects, but refer to different types of information. In this guide, we'll explore how to handle such a JSON response in a React application to effectively display the data.

The Problem

Consider the following JSON data:

From this structure, you may notice that the attributes array has several objects that all contain a displayName and value. Each attribute (name, Gender, Phone_number) needs to be displayed in a React component, but it can be tricky to extract the right value if you’re unfamiliar with the data structure.

The Solution

To display this data in a React component, we can effectively map over the data array and filter the attributes based on the displayName value. Below, I'll guide you through implementing a solution.

Step 1: Basic Setup

You should already have your React project set up to load the JSON data. First, let's ensure we import the necessary React library and our JSON data.

Step 2: Create the Main Component

Next, we'll create our main component. Inside this component, we will map through the data array and display the relevant data.

Step 3: Create a Helper Function

To clean up the code and avoid repetitive filtering, let's create a helper function getAttributeValue. This function will extract the value for us based on the displayName.

Step 4: Complete Code

Putting everything together, your final code looks like this:

Conclusion

This approach allows you to systematically extract and display data from a JSON array of attributes in your React applications. By utilizing a helper function to streamline the process of retrieving attribute values, you can keep your code tidy and maintainable. Now you are better equipped to handle complex JSON structures and display them effectively in your UI!
