How to Properly Populate Nested Array of Object Data in React-Bootstrap Cards

Rendering JSON data in a user-friendly format can sometimes be challenging, especially when dealing with nested arrays of objects in React. When using React-Bootstrap cards to display this data, developers often face the issue of how to properly structure the cards so that each card holds an individual piece of information. In this guide, we'll explore how to correctly populate each card with data from a nested array and avoid the common pitfall of rendering everything in a single card.

Understanding the Problem

Imagine you have a JSON object that contains multiple entries, each with an array of objects. The goal is to display each object from this array in its own card. Many developers mistakenly render all items within a single card, leading to a cluttered and confusing user interface.

Here, we will break down the solution step-by-step, using the provided code as a foundation to correct this issue.

The Mock Data

First, let's take a look at the mock data we are working with. The data is structured like this:

As you can see, each row contains several cells, and we need to make sure that each of these cells renders its own card.

The Solution

Step 1: Create the Card Component for Each Cell

We will modify the getData function to create a new card for each cell, instead of nesting all cells within a single card. Here’s how to adjust that function:

Step 2: Map Through Each Row's Cells

Next, we need to ensure our completeCardData function maps through the cells of each row, calling the getData function for each cell:

Final Code Implementation

Putting it all together, your final component might look something like this:

Conclusion

By correctly structuring your getData and completeCardData functions, you can easily render the data from a nested array of objects into individual React-Bootstrap cards. Each card now displays its own unique piece of data, creating a clean and readable interface for users.

If you find yourself struggling with similarly structured data in the future, remember to break down the components and map through your data correctly. This approach will save you from cluttered and confusing layouts.

Happy coding!
