fetch-readablestream

library0.2.0jsnpmunverified

Compatibility layer for efficient streaming of binary data using WHATWG Streams. Current stable version is 0.2.0, with no recent releases or cadence. It provides a consistent cross-browser API to stream HTTP responses as ReadableStream, falling back to XMLHttpRequest with moz-chunked-arraybuffer in Firefox, and TextEncoder in other browsers. Differentiates from native fetch by enabling streaming in older browsers, unlike stream-http which uses callbacks.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

fetchStream

✓ import fetchStream from 'fetch-readablestream'

✗ const fetchStream = require('fetch-readablestream')

Package is ESM-only; CommonJS require will fail.

fetchStream (global)

✓  window.fetchStream('...')

Global usage via dist bundle, no import needed.

Demonstrates streaming a response body as text using fetchStream and a ReadableStream reader.

import fetchStream from 'fetch-readablestream'; async function streamResponse(url) { const response = await fetchStream(url); const reader = response.body.getReader(); const decoder = new TextDecoder(); let result = ''; while (true) { const { done, value } = await reader.read(); if (done) break; result += decoder.decode(value, { stream: true }); } decoder.decode(); // flush return result; } streamResponse('https://example.com').then(console.log);

Debug

Known issues

gotchafetchStream only supports GET requests; POST not implemented.

fix

Use native fetch or XMLHttpRequest for POST.

affects: >=0.0.0

deprecatedAbortController support is limited; need polyfill in many environments.

fix

Include abortcontroller-polyfill if targeting older browsers.

affects: >=0.1.0

gotchaResponse.body may be null if not streaming; always check before reading.

fix

Guard with if (response.body) before calling getReader().

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: fetchStream is not a function

CommonJS require used instead of ESM import.

fix

Use import fetchStream from 'fetch-readablestream'

TypeError: Failed to execute 'getReader' on 'ReadableStream': reader is already active.

Multiple concurrent reads on same stream without releasing reader.

fix

Close reader after use with reader.releaseLock() or let stream cancel.
