This directory contains the Blink implementation of the WHATWG Streams standard: https://streams.spec.whatwg.org/. There is also a legacy streams implementation.

V8 Extras ReadableStream Implementation

• ByteLengthQueuingStrategy.js
• CountQueuingStrategy.js
• ReadableStream.js
• ReadableStreamExperimentalPipeTo.js
• ReadableStreamController.h
• ReadableStreamOperations.{cpp,h}
• UnderlyingSourceBase.{cpp,h,idl}
• WritableStream.js

These files implement ReadableStream using V8 extras. All new code should use this implementation.

Old streams

• Stream.{cpp,h,idl}

These files support an old streams spec. They should eventually be removed, but right now XMLHttpRequest and Media Streams Extension code in Blink still depends on them.
