gratuitous reloading when clicking on a manifest in a collection

[eroux]

Exemplified in http://eroux.fr/buguv2/buguv2.html :

• open collection "Derge Kangyur" (which unfolds the collection)
• click on any volume
• click on another volume

the entire UI gets reloaded and the collection is folded again.

(note that looking at the developer console, UV also reruns requests on the collections and manifests URLs. Most of the time they're cached in the browser so it's sort of ok, but I don't think it's a good thing to do)

here's a screencast of what I see (Firefox / Linux):

I'm seeing gratuitous reloading in the main panel on my site - https://archive.kingsfund.org.uk

We're thinking to use https://github.com/edsilv/utils/blob/master/src/Utils.ts#L328 to cache manifests in local storage in manifold here: https://github.com/IIIF-Commons/manifold/blob/master/src/Manifold.ts#L5 (more discussion on #community-sprint https://universalviewer.slack.com/archives/CA2RSMW31/p1562592551084100)

Great, thanks! That will solve the network calls, but I'm not sure this is really the core of this issue though, which is more a UI reloading problem than a network problem

@stephenwf and I have been talking about this. Really we need to think about moving over to webpack or similar. The UV Steering Group call is on Thursday and the roadmap for future community sprints is on the agenda. I think everyone understands that the UV is a very long-running project and in need of a bit of a refresh - it's just how to plan this in a way that works for everyone :-)

sure! looking at what Mirador does, it sure looks like a big update is a good thing! I can't say I'm not annoyed by being in the space in between an unmaintained Mirador 2 and a not ready Mirador 3, but I still think it's going in the right direction

[edsilv]

I think the UV is in a good place in terms of being able to incrementally improve (we're calling it the "Ship of Theseus" plan). It's already highly componentised, and TypeScript makes refactors ridiculously easier. At the end of the day the BL, NLW, etc are in for the long haul. We have to move slowly, but (to labour the nautical analogies) we've charted a course and the winds are at our backs :-)

good to read! :)
