📚 Introduction
In this Tutorial, we will learn how to run multiple API calls in a single function in React. The APIs we will be using are related to the NBA, and we will be rendering a player's name and photo. Before we begin, I want to express my gratitude to all the subscribers for helping us reach 50 subscribers. Don't forget to like the video and let's jump right into it!
🏗️ Setting up the React App
To start, we need to create a React app. Assuming you have already set up your development environment, open your terminal and create a new React app by executing the following command:
npx create-react-app my-app
Replace "my-app" with your preferred name for the app. Once the app is created, navigate into the app's directory by running:
cd my-app
📦 Installing Axios
Next, we need to install Axios, a popular JavaScript library for making HTTP requests. Axios will help us fetch data from the NBA APIs efficiently. In your terminal, run the following command:
npm install axios --save
This command will install Axios and save it as a dependency in your project's Package.json file.
💻 Importing useState and useEffect
To handle state and side effects in our React component, we need to import the useState and useEffect hooks. In your code editor, open the file where you want to implement the multiple API calls. At the top of the file, import useState and useEffect as follows:
import React, { useState, useEffect } from 'react';
import axios from 'axios';
The useState hook will allow us to manage state in a functional component, and the useEffect hook will enable us to execute side effects, such as fetching data, when necessary. We also import the axios library, which we installed earlier.
🌐 Fetching Data from NBA APIs
Now that we have set up our React app and imported the required dependencies, we can start fetching data from the NBA APIs. We will need two URLs from the APIs: one for fetching the player's name and another for fetching the player's photo.
To get the URLs, open the first link provided in the description below. Scroll down until you find the appropriate endpoint for fetching player data. Copy the URL for this endpoint.
Next, find the Second link in the description below, which corresponds to the player's photo. Copy the URL for this endpoint as well.
Once we have the URLs, let's create variables to store them in our code. In your component function, add the following code:
const playerAPI = 'URL_FOR_PLAYER_DATA';
const playerPicAPI = 'URL_FOR_PLAYER_PHOTO';
Replace URL_FOR_PLAYER_DATA
with the actual URL you copied for fetching the player's name, and URL_FOR_PLAYER_PHOTO
with the URL for fetching the player's photo.
🔄 Making Multiple API Requests
Now that we have our URLs, we can proceed to make the API requests. To make multiple requests simultaneously, we will use the axios.all
function. In your component function, add the following code:
axios.all([
axios.get(playerAPI),
axios.get(playerPicAPI)
])
.then(axios.spread((playerRes, playerPicRes) => {
const playerName = playerRes.data.firstName;
const playerPic = playerPicRes.config.url;
// Perform further actions with the data
}))
.catch(error => {
console.error('Error fetching data: ', error);
});
The axios.all
function accepts an array of axios requests. In this case, we are passing two axios requests: one for the player data and another for the player photo. The axios.spread
function allows us to access the responses of both requests as separate parameters.
Inside the .then
block, you can perform further actions with the retrieved data. For now, we have extracted the player's name and the URL for their photo. Feel free to modify this code to suit your specific needs.
In case of an error, the .catch
block will handle it and log an error message to the console.
📥 Retrieving Data from API Responses
Now that we have successfully made the API requests, let's retrieve the data from the API responses. Create two state variables, playerName
and playerPic
, and corresponding setter functions using the useState
hook. Update your code as follows:
const [playerName, setPlayerName] = useState('');
const [playerPic, setPlayerPic] = useState('');
These state variables will hold the player's name and photo URL, respectively.
🖼️ Displaying the Player's Name and Photo
In this step, we will render the player's name and photo on the screen. Inside your component's return statement, add the following code:
<div>
<h2>Player Name: {playerName}</h2>
<img src={playerPic} alt="Player's Photo" />
</div>
This code will create a heading with the player's name and an image element displaying the player's photo. The player's name will be fetched from the playerName
state variable, and the photo URL will be fetched from the playerPic
state variable.
🔚 Conclusion
Congratulations! You have learned how to run multiple API calls in one function in React. By using the axios.all
function, you can efficiently fetch data from multiple APIs. Remember to handle the API responses and store the retrieved data in appropriate state variables. With this knowledge, you can now expand your applications to integrate various APIs and display the data as needed.

FAQ
Q: Can I make multiple API calls simultaneously in React?
A: Yes, you can use the axios.all
function from the Axios library to make multiple API calls in one function.
Q: How do I handle errors while making API calls?
A: You can use the .catch
method to handle errors and log them to the console or display an error message to the user.
Q: Can I fetch data from different API endpoints in one function?
A: Absolutely! Using the axios.all
function, you can pass an array of axios requests for different API endpoints and retrieve the data from each response.
Q: What other libraries can I use for making HTTP requests in React?
A: Besides Axios, you can also use libraries like Fetch API, Superagent, or jQuery's AJAX methods for making HTTP requests in React.
