How to Effectively Call JSON Data Stored as a Variable in Different React Components

In modern web development, effective data management and communication between components are crucial for creating dynamic applications. If you're working with React and need to call JSON data stored as a variable in a different component, it can feel daunting at first. In this post, we’ll guide you step by step to understand how to pass data seamlessly between your components using props, ensuring your application remains organized and efficient.

The Problem: Accessing JSON Data in Different Components

Solution Overview

To access this JSON data in different components, you have two main options:

Prop Drilling: Pass data down from a parent component to child components.

State Management Libraries: Use libraries like Redux for larger applications.

For the purposes of this guide, we'll focus on the first method, prop drilling, as it is commonly used for simpler applications.

Step-by-Step Solution

Step 1: Create a Parent Component

The first step is to fetch your JSON data in a parent component. This component will be responsible for retrieving the data and passing it to its child components.

Breakdown of the Code:

We declare a new functional component ParentComponent.

Inside it, we create a state variable profiles to hold the fetched JSON data.

Using useEffect, we make an API call with Axios to retrieve the data.

Once we receive the data, we update the profiles state via setProfiles.

Finally, we render child components (ProfileOne and OtherComponent) while passing the profiles data as props.

Step 2: Modify the Child Component

In the child component, you will now receive the profiles data as props, making it easily accessible.

Explanation:

For each profile, we display the name and other properties (like major).

Make sure to include a unique key prop for each item in the list to avoid performance issues and to ensure React properly manages re-renders.

Conclusion

By implementing the above practices, you can effectively call and display JSON data stored in parent components across various child components. This method not only keeps your application organized but also promotes reusable components.

If your application grows complex or needs a more robust state management solution, consider using Redux or Context API for handling data across your components efficiently.

Now you're all set to handle JSON data in your React applications with confidence! Happy coding!
