A JavaScript library that provides the WHATWG Fetch API as a global polyfill, working consistently in both Node.js and browsers (via Browserify/webpack). It is built on top of GitHub's fetch polyfill so the same fetch code runs client and server side.

Use cases

• make HTTP requests with fetch in both Node and the browser
• use the same fetch code in isomorphic/universal JavaScript apps
• polyfill fetch in older browsers
• fetch JSON from an API in a server-rendered app
• avoid branching between node-fetch and browser fetch

When to choose

• you need one fetch implementation shared between client and server code
• you're maintaining an older isomorphic codebase already using it
• you want a drop-in global fetch polyfill for Node and Browserify bundles

When to avoid

• you don't want a library that mutates the global fetch (use fetch-ponyfill or cross-fetch instead)
• you only target modern browsers or Node 18+ with native fetch
• you need a maintained, actively developed solution
