TPAC 2021 Web Components Meeting

[mfreed7]

Forgive me if this is already being discussed somewhere, but are there plans for a Web Components meeting at TPAC this year?

Breakouts are October 18-22, and apparently proposals are due in two days, Friday October 8, 2021.

I see one item on the agenda already, but nothing else. Perhaps we're just planning to propose individual sessions on topics, rather than a coordinated agenda of discussions?

The session that the Web Components Community Group has proposed is definitely more about sharing community priorities rather than to discuss or clarify any in progress specifications. That being so, I do hope that there is appetite for sessions focusing directly on things like:

• constructible stylesheets, adoptedStyleSheets, and import assertions
• Scoped custom element registries
• cross root aria
• Form participation
• declarative shadow DOM
• Amongst other things

Happy to support getting additional sessions onto the wiki however I can!

Yeah, I added the minimal info I could think of. I don't recall past proposals and whether they had better descriptions or whatnot. I also don't know if something special was done to request a longer half-day like we've had before and whether that's still a thing with TPAC online. So please anyone edit what I put up there if you can improve it!

@mfreed7 @justinfagnani do you have an idea what the agenda would be? For a longer meeting it would be easier to hold one after TPAC somewhere.

[justinfagnani]

I have a few issues I'd like to deep dives into:

• Scoped custom element registries
• Composed selection ranges
• Constructible stylesheets
• Open-stylable shadow roots
• Several issues around SSR use case: declarative shadow DOM, associating them with CSS modules, ElementInternals, etc.

Whether we need a longer session might depend on how many of those issues implementors want to talk about as well. I'm not sure what everyone's areas of interest are these days.

[annevk]

Of those, selection seems worthwhile talking about to me in light of the proposal. It's not clear to me the others made (enough) progress since the last time they were discussed.

[mfreed7]

Ok, I just added an item to discuss the selection proposal.

There was a separate meeting on selection that is summarized here: #79 (comment).
