How to Parse a Property of a React Object Efficiently

When working with APIs in React, it's common to receive complex data structures as responses. A typical challenge developers face is parsing these responses to extract the necessary information. In this guide, we'll explore how to parse responses returned from a service in a more accessible way.

The Problem

Let's imagine you've made a request using the ReviewerService.getReviewers() method, which returns an array of reviewer objects. Each object contains several properties, including one that stores responses in a JSON string format. Below is a simplified version of the data structure you might encounter:

Now, your goal is to populate the state in your React component with these reviewers while also parsing the responses property so that you can easily manipulate it later.

The Solution

To efficiently parse the property in question, you can use the componentDidMount lifecycle method in your React component. Here’s how to implement the solution step-by-step:

Step 1: Fetch the Reviewers

You will first want to fetch the reviewers when your component mounts. Use the async/await syntax for cleaner code:

Step 2: Parse the Responses

Instead of directly setting the state, use the map function to iterate through each reviewer and parse the responses. Here's the code for that:

Step 3: Set the State

Finally, update your component’s state with the new array of reviewers:

Conclusion

By following the steps outlined above, you can effectively parse properties from an array of objects returned from an API in React. This process makes the data more manageable and allows easy access to individual properties in your application.
