response-iterator

Create an async iterator for response bodies from Fetch, node-fetch, cross-fetch, Axios, or Node streams.

Install

npm install response-iterator

Use with fetch

import responseIterator from 'response-iterator';

const res = await fetch('https://raw.githubusercontent.com/kmalakoff/response-iterator/master/package.json');

const decoder = new TextDecoder();
let data = '';
for await (const chunk of responseIterator(res)) {
  data += typeof chunk === 'string' ? chunk : decoder.decode(chunk, { stream: true });
}
data += decoder.decode();
console.log(JSON.parse(data).name); // "response-iterator"

The example uses the global fetch available in modern Node.js and browsers. On older Node.js versions, pass a response from a fetch implementation such as cross-fetch. Yielded chunks keep the underlying body type, so decode Uint8Array chunks before treating them as text.
