How to Store Multiple API Calls in One React State Using Axios

Are you working on a React project where you need to fetch data from multiple APIs that return similar, but distinct values? If this sounds familiar, you might be facing a challenge with how to organize and store this data effectively. In this guide, we’ll explore a solution that allows you to streamline your data management by storing all your API results in a single state. This approach not only simplifies your code but also enhances efficiency when rendering results.

The Problem

When you're working with multiple APIs that serve the same data types, but from different sources, it can be cumbersome to manage separate states for each API's data. For example, you might have the following state declarations in your code:

If you have to make Axios calls to fetch data from both APIs, the resulting complication arises when you want to combine or display this data through .map(). With separate states, concatenating and rendering the data becomes inefficient and complex.

The Solution

The good news is that you can simplify this process. Here’s a clean way to store all fetched data from multiple APIs into one single React state using Axios.

Step-by-Step Guide

Combine States into One: Instead of having multiple states, you only need one state for storing all your data. So, let's modify our state declaration to look like this:

Prepare Your API Calls: Define the headers you will use for your API calls, and create an array of URLs that you want to fetch data from:

Using Promises: Instead of calling each API one by one, take advantage of Promise.all(). This method allows multiple requests to be made concurrently which results in better performance.

Explanation of the Code

Promises: By using urls.map() to create an array of promises for each API call, we ensure that all requests are sent simultaneously.

Promise.all(): This function waits for all promises to resolve, making it easier to work with the results.

Data Concatenation: We loop through the responses and concatenate them into a single array, which we then set in our infoData state.

Rendering the Data

Once you have all of your data stored in infoData, you can easily render it using .map() in your component as follows:

Each item can now be accessed effortlessly from a single state, making your code more organized and easier to maintain.

Conclusion

In conclusion, managing multiple API calls in a React application doesn't have to be complicated. By using a single state with Promise.all() and Axios, you can easily fetch, combine, and display your data. This streamlined approach saves you time and effort in the long run, giving you more flexibility when handling API responses.

By consolidating your API data into one state, you can enhance the maintainability of your code while making your application more efficient. Happy coding!
