#187: Review request for ResizeObserver

Visit on Github.

Opened Aug 10, 2017

Hello TAG!

I'm requesting a TAG review of:

Name: ResizeObserver
Specification URL: https://wicg.github.io/ResizeObserver/
Explainer: https://github.com/WICG/ResizeObserver/blob/master/explainer.md
Primary contacts: @atotic

Further details (optional):

Relevant time constraints or deadlines: Chrome would like to ship in M62 (Aug 31st, 2017 branch point)
I have read and filled out the Self-Review Questionnare on Security and Privacy. The assessment is here.
I have reviewed the TAG's API Design Principles

Previous discussions/implementations:

Many of the interesting design decisions have been discussed on ResizeObserver github issues.

Chrome has implemented ResizeObserver behind a flag. Firefox has worked on ResizeObserver implementation. ResizeObserver has been discussed at TPAC meeting in Lisbon 2016.

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 [@atotic]

Peter: Had some feedback about adding yet another 'single box' idea to the platform, not accounting for fragmentation; there was some pushback on implementation constraints.

Hadley: Also Alex noted timing of feedback--is it too late for feedback?

Peter: Only in Chrome?

Alex: TAG design review is not moved to early in the design process (Intent to Implement).

Peter: TSLC<1wk (time since last comment), move out and revisit?

Peter: 2 weeks out.
