React Axios | Advanced Tutorial for Axios with React Js for a REST API

In this tutorial, we will explore how to use Axios with React to make advanced HTTP requests to a REST API. Axios is a popular JavaScript library for making HTTP requests and can be easily integrated with React for handling data from a server API.

Setting up Axios in React

Before we can start using Axios in our React project, we need to install the Axios library. We can do this by running the following command in our terminal:

npm install axios

Once Axios is installed, we can use it in our React components to make HTTP requests to a server API. Here is a basic example of how to use Axios in a React component:

import React, { useEffect, useState } from 'react';
import axios from 'axios';

function App() {
  const [data, setData] = useState([]);

  useEffect(() => {
    axios.get('https://api.example.com/data')
      .then(response => {
        setData(response.data);
      })
      .catch(error => {
        console.log(error);
      });
  }, []);

  return (
    

      {data.map(item => (
        
{item.name}
      ))}
    
  );
}

export default App;
    

Advanced Axios Usage

Axios provides a wide range of options for making HTTP requests, including support for request and response interceptors, custom headers, authentication, and more. Here are some advanced features of Axios that can be used in a React application:

• Request Interceptors: Allows us to modify the request or handle errors before it is sent to the server.
• Response Interceptors: Allows us to modify the response data or handle errors before it is passed to the calling function.
• Custom Headers: Allows us to add custom headers to the request, such as authentication tokens or content types.
• Authentication: Axios supports various authentication mechanisms, such as basic authentication, token-based authentication, and OAuth.

Conclusion

In this tutorial, we have learned how to use Axios with React to make advanced HTTP requests to a server API. With its powerful features and easy integration with React, Axios is a great choice for handling data from a RESTful API in a React application. By using Axios, we can easily manage our HTTP requests and handle response data effectively.
