Fetch JSONP

Fetch JSONP is a small JavaScript library that provides a Fetch-like API for JSONP requests. Standard Fetch does not support JSONP, so this package fills that specific compatibility gap. Developers can call fetchJsonp, receive a promise, and parse the response with a familiar .json() flow. The library supports custom callback parameter names, custom callback function names, and request timeouts. It also documents the difference between regular JSON APIs and JSONP endpoints, which helps avoid common syntax errors. fetch-jsonp is useful for legacy APIs, older cross-domain integrations, and browser applications that still need JSONP behavior.
