Axios HTTP Client

Axios is a promise-based HTTP client for the browser and Node.js created by Matt Zabriskie in 2014, providing a simple, consistent API for making HTTP requests with automatic JSON transformation, request and response interception, cancellation through AbortController, progress tracking for uploads and downloads, timeout handling, cross-site request forgery protection, and HTTP basic authentication, adopted by over six million weekly npm users and companies including Facebook, Amazon, and Microsoft as the most popular HTTP client library in the JavaScript ecosystem. The request API provides simple methods including axios.get, axios.post, axios.put, axios.patch, and axios.delete for common HTTP verbs, with a general axios function accepting a configuration object for custom requests, and concurrent requests through axios.all and axios.spread, enabling developers to make HTTP requests with minimal boilerplate while supporting complex configurations through a unified interface. The interceptors enable global request and response transformation, with request interceptors modifying outgoing requests for adding authentication headers, logging, or rate limiting, and response interceptors processing incoming responses for error handling, data transformation, or retry logic, providing a middleware-like pipeline for HTTP communication that centralizes cross-cutting concerns. The automatic JSON handling parses JSON response bodies and serializes request bodies, with configurable transformRequest and transformResponse functions for custom serialization formats including XML, form-encoded, and multipart. The cancellation API uses AbortController for cancelling in-flight requests. The progress events for file uploads. The timeout configuration. The xsrfCookieName and xsrfHeaderName for CSRF protection. Designed for JavaScript and TypeScript developers.
