Applications use it to send requests to web services and handle their responses in browsers or Node.js. It is a library—not an API or a server—and it provides a consistent request interface along with options such as interceptors, data transformation, cancellation, and form serialization.
What Axios does
When a JavaScript application needs data from a web service, it makes an HTTP request. Axios provides functions for creating that request and returning its result as a Promise, which can be handled with await or Promise methods such as .then() and .catch().
For example, a browser app might request a user record from its own server. The server—not Axios—defines the endpoint and decides what response to return. Axios is the client-side or server-side code that makes the request.
Where Axios runs
Axios supports JavaScript in both browsers and Node.js. The same high-level API can be used in either environment, while the networking mechanism differs: Axios’s introductory documentation describes XMLHttpRequest in browsers and Node.js’s native HTTP module on the server. See the Axios introductory documentation.

How to make a request
A request can be made with a method helper such as axios.get, or by passing a configuration object. This example requests a user record and handles a failure with catch:
import axios from 'axios';
try {
const response = await axios.get('/user');
console.log(response.data);
} catch (error) {
console.error('Request failed:', error);
}Axios also provides aliases for GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests. The URL, method, and other request settings depend on the endpoint and what the application needs to send.

Features that shape an Axios request
Shared configuration with instances
An application can create an Axios instance with common settings, such as a base URL and timeout, rather than repeating those settings for every request. This is useful when several calls target the same service.
Interceptors and data transformation
Request and response interceptors let application code run logic around requests—for example, applying shared handling or responding to errors. Axios also supports transforming request and response data, including JSON serialization and parsing.

Axios documents support for multipart/form-data and application/x-www-form-urlencoded serialization, cancellation, and progress capture. Its introductory documentation also lists bandwidth limits for Node.js. These capabilities can help with uploads and other application-specific request flows, but they do not remove the need to handle failures and server responses.
XSRF support
The Axios README describes client-side cross-site request forgery (XSRF) support. Treat it as one tool in an application’s defenses, not as a guarantee that an application is secure: overall protection depends on how the server and client are configured and how the application handles requests.
Rank #4
Install Axios and configure a timeout
The Axios README documents installation through package managers, including npm, Yarn, pnpm, Bun, and Deno; it also documents browser CDN builds. For example, with npm:
npm install axiosSet a timeout appropriate to the application’s request in production. The project warns that without one, a stalled request can hang indefinitely. A timeout limits how long the client waits; it does not ensure that the server completed or did not complete the operation.
Cancellation in new code
Axios supports request cancellation. The README marks its older CancelToken interface deprecated since v0.22.0 and advises against using it in new projects. Choose the current cancellation API documented for the Axios version in use rather than starting with the deprecated interface.
When Axios is a reasonable choice
Axios can be useful when an application wants a shared request interface across browser and Node.js code, or needs features such as interceptors, configured instances, or form serialization. Whether it is preferable to a runtime’s built-in HTTP or Fetch APIs depends on the project’s runtime support, needed configuration, existing dependencies, and desired features. The project documentation does not establish that Axios is universally faster, safer, or better than those alternatives.
The Axios v1.x README is the best starting point for current usage details: Axios README. The separate introductory documentation repository is archived and read-only, so use it for background rather than assuming it reflects every current usage detail.
