Error Handling using Axios in React JS | Error Handling | React JS Tutorial (full course) – #55

When working with APIs in React JS, error handling becomes an important aspect of the development process. Axios is a popular library used for making HTTP requests in React and in this tutorial, we will cover how to handle errors when using Axios in a React JS application.

Using Axios for HTTP Requests in React JS

Axios is a promise-based HTTP client for JavaScript that has become the de-facto standard for making HTTP requests in modern web applications. It provides an easy-to-use API for handling HTTP request and response data.

When working with Axios in React JS, it’s important to handle potential errors that may occur during the HTTP request process. This could be due to network issues, server errors, or even client-side validation errors. Thankfully, Axios provides an easy way to handle these errors using its built-in error handling features.

Error Handling with Axios in React JS

When making an HTTP request using Axios in React JS, we can use the `.catch` method to handle any errors that may occur during the request. This method takes a callback function as an argument, which will be executed when an error occurs.

Here’s an example of how to handle errors using Axios in a React JS component:

“`jsx
import React, { useEffect } from ‘react’;
import axios from ‘axios’;

const MyComponent = () => {

useEffect(() => {
axios.get(‘https://api.example.com/data’)
.then(response => {
// Handle successful response
console.log(response.data);
})
.catch(error => {
// Handle error
console.error(‘Error fetching data: ‘, error);
});
}, []);

return (

);
};

export default MyComponent;
“`

In the above example, we make a GET request to `https://api.example.com/data` using Axios. We then use the `.catch` method to handle any errors that may occur during the request. The `error` object passed to the callback function contains information about the error, such as the error message and status code.

Conclusion

Error handling is an essential part of building robust and reliable web applications, and when working with Axios in a React JS application, it’s important to handle potential errors that may occur during HTTP requests. By using the `.catch` method, we can handle any errors that occur during the request and provide a graceful user experience.
