path-source

Read files in Node.js or fetch URLs in browsers as standard WhatWG readable streams. Version 0.1.3 provides a unified API for streaming file I/O and HTTP responses. Designed for incremental data processing, it returns a ReadableStream reader with `read()` and `cancel()` methods. In Node, it wraps file streams; in browsers, it uses the Fetch API with streaming support when available, falling back to XMLHttpRequest. Lightweight and zero-dependency for the core feature, but requires `array-source` in older browsers. Part of a family of stream sources by Mike Bostock.
