## What it is
dio is a powerful HTTP client library for Dart and Flutter supporting global configuration, interceptors, FormData, request cancellation, timeouts, file upload/download, and custom adapters. It is a monorepo containing the core package plus plugins like cookie management and HTTP/2 adapters.

## Use cases
- make HTTP requests from a Flutter app
- add interceptors for auth tokens and logging
- upload and download files with progress
- cancel in-flight HTTP requests
- configure global timeouts and base URLs
- use HTTP/2 in Dart applications

## When to choose
- building Flutter or Dart apps that talk to REST APIs
- you need interceptors, cancellation, or file transfer out of the box
- you want a mature, widely adopted Dart HTTP client

## When to avoid
- writing non-Dart/Flutter projects
- you only need a minimal fetch-style client without extras
- server-side Dart needing deep platform-native HTTP stack integration without adapters

## Facets
- artifact type: library
- maturity: stable
- function: http-client, middleware, file-upload
- domain: web-development, mobile-development, apis, cross-platform
- platform: cross-platform
- tags: flutter, http-client, interceptors, request-cancellation, formdata, pub-package, mobile, web-server
