Hello TAG!

I'm requesting a TAG review of:

• Name: ReadableStream pipeTo() and pipeThrough()
• Specification URL:
  • https://streams.spec.whatwg.org/#rs-pipe-to
  • https://streams.spec.whatwg.org/#rs-pipe-through
• Explainer, Requirements Doc, or Example code:
  • This section contains a high-level overview: https://streams.spec.whatwg.org/#pipe-chains
  • Some additional examples: https://streams.spec.whatwg.org/#example-basic-pipe-to
  • A related FAQ: https://github.com/whatwg/streams/blob/master/FAQ.md#whats-with-pipeto-vs-pipethrough
• Requirements document: https://github.com/whatwg/streams/blob/master/Requirements.md#composing-streams
• Primary contacts: @domenic, @tyoshino, @ricea

Further details (optional):

• Relevant time constraints or deadlines: We are hoping to launch in Blink in M59, for which the branch point is in a couple weeks
• I have read and filled out the Self-Review Questionnare on Security and Privacy: not really applicable here
• I have reviewed the TAG's API Design Principles

You should also know that...

This feature is closely related to writable streams, #163.

We'd prefer the TAG provide feedback as (please select one):

• open issues in our Github repo for each point of feedback
• open a single issue in our Github repo for the entire review
• leave review feedback as a comment in this issue and @-notify [github usernames]
