fetch-everywhere

Isomorphic WHATWG Fetch API that works in node.js, browsers, webpack, browserify, and react-native by providing a global fetch function. Version 1.0.5, last updated in 2016. Built on top of isomorphic-fetch and GitHub's WHATWG Fetch polyfill. Key differentiator: claims to support all JavaScript environments without per-environment configuration. However, the package is minimally maintained and depends on the outdated isomorphic-fetch; modern Node.js versions (18+) include native fetch, making this polyfill obsolete for most use cases.
