fetch-readablestream

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.
