Axios call in Node.js

In this article, you will learn about the Axios call in Node.js with its usage.

What is Axios?

Axios is a minimal HTTP client that operates in tandem with Node.js and browser environments. It is built on the http service found in Angular.js. Because it implements the native Promise API of JavaScript ES6, it is the best option for managing asynchronous operations. Axios also has built-in functionality for automated JSON data transformation, request cancelation, and transformations of both responses and requests.

Installing Axios

You must install Axios using npm (Node Package Manager) before utilizing it in a Node.js application. Execute the below command within your terminal:

After installation, your project may need it:

Basic Usage:

The axios.get function may be used to create a straightforward GET request. For instance, you may write the following to retrieve data from a public API:

Install the axions:

Run the code:

This code logs the return data after sending a GET request to the given URL. If a mistake occurs, it is detected and recorded on the console.

Making POST Requests

Additionally, Axios makes it simple to use a POST request to submit data to an API. As an illustration:

Output:

Explanation:

In this instance, postData is sent to the given URL, and the console logs the response data.

Managing Promises and Async/Await:

Managing asynchronous activities is easy since Axios has promise functionality.

Run the code:

Similarly, for POST requests:

Output:

Configuring Requests

Axios offers many methods for configuring requests. For example, you may modify the timeout, headers, and other settings:

Output:

 node script.js 

Handling Errors

Axios provides strong error-handling features. The error object provides helpful information when a request is unsuccessful.

Output:

Output:

Output:

Interceptors

With interceptors, you may execute your code or make changes to the request before it is submitted or before the catch handles the answer. It helps with logging, adding authentication tokens, and changing request data.

Output:

 node script.js 

Cancelling Requests

Axios also supports cancelling requests using the CancelToken feature. The CancelToken feature is particularly useful for scenarios. These scenarios are ones where you want to abort a request based on certain conditions.

Output:

Axios Instance:

The Axios instance's default settings can be made and used again for various requests. Setting up base URLs is part of this. It is also possible to specify headers and other parameters in one place. It is beneficial.

Output:

 node script.js 

Conclusion:

In conclusion, Axios serves as a flexible and strong HTTP client, boasting several features that simplify managing HTTP requests and responses in Node.js. It offers a promise-based API and supports async/await. Moreover, it includes interceptors and request cancellation, making it an excellent choice for developers. Axios allows you to create reliable and effective apps. It holds regardless of the complexity of your handled situations or the basic GET. It also holds for POST requests.
