F2F

[yoav] Please sign up

… note that we have two different forms, you need to sign up on both

… first day will be split into two parts

gaps and needs

….. second half focused on new platform features and areas we need to focus
on

… anything missing on the agenda

?

[ryosuke] for the use cases, what worked well for the web components f2f is
presenting both how current APIs are being used (what works), not just
wishlist of things to add

[todd] the goal is to get people to present how they’re using, plus where
they had friction

[ryosuke] lgtm

[ryosuke] do we want to talk about how to (re)structure our spec work?

[yoav] we can recap our state at the end of the day

… CDN representation: we have Nic, but we’ll see if we can find others

… for the second day, we have ~8 people registered so far for issue
hackathon

… if you can or willing to join, please subscribe on the form

[plh] I’ll be there

[ryosuke] I’m TBD for second day, will be there on first day

… btw, TPAC schedule is out, we should planning the agenda

… we’re meeting Monday and Tuesday

[yoav] yep, we can kick that off after f2f
Element Timing & Shadow DOM

[npm] element interaction with shadow DOM: issue
<https://www.google.com/url?q=https://github.com/w3c/webcomponents/issues/816&sa=D&ust=1559557657101000>

… the issue is that some components may be very large, which hide a lot of
details

… on the other hand, there is encapsulation

… one proposal is to have the PO be scoped to shadow root instead of window

… this way the web component author can scope and then expose up to the
document

… another approach is to treat elements with open shadow as something we
can report

[yoav] is the problem clear?

… for RT, we expose fetches made by encapsulated logic

[alex] it would be useful to know where one would want to hide this
information?

…

[todd] would it make sense to ask a couple of big folks using this?

… alternative, we can start by not exposing

[npm] agree, good idea to ask major users

… but they may have different opinions from those who distribute components

[steven] I can check with our team (SalesForce) to get their feedback

[ryosuke] getComposedRange approach might be a route to investigation

… maybe there is a way to add getEntries / PO could take a list of shadow
roots that developer has access to

Registry vs registration model

[yoav] discussed on the last call, Philippe created a note to create the
registry

… Ryosuke chimed in favor of registration model?

[ryosuke] registration model could work, I was echoing Boris’s concern that
if we just have one list that advertises that features that may not be
supported

… but if we have tests in each specification

[plh] we could add false positive test on the registry spec itself

… I will add a test and move forward on publishing the registry

[yoav] we also talked about other parameters, but we could add those later

… e.g. buffered flag and number of entries

… but that is non-blocking

[plh] can you please file an issue to track the above?

… I will setup auto publishing

… any objections?

+1’s from the group — onwards!
