## What it is
A small JavaScript library implementing JSONP for making cross-domain requests from the browser via script tag callbacks. It supports configurable callback parameters, timeouts, and request cancellation.

## Use cases
- fetch data from a cross-domain API without CORS
- make JSONP requests with timeout handling
- cancel an in-flight JSONP request
- customize the callback query parameter name
- consume legacy APIs that only support JSONP

## When to choose
- you need to call an old API that only supports JSONP
- you must support browsers without CORS or fetch
- you want a tiny, dependency-free JSONP client

## When to avoid
- the API supports CORS - use fetch or axios instead
- you need modern request features like headers or POST
- starting a new project where JSONP is obsolete

## Facets
- artifact type: library
- maturity: maintenance
- function: http-client
- domain: web-development, frontend, apis
- platform: browser
- tags: p, cross-domain, fetch, legacy-browsers, nodejs
