Interesting change. Why?
There was a problem hiding this comment.
The meta doesn’t match any valid resource type (no key) so it gets omitted. This may be wrong but it’s helpful on the client if we can assume metas are resources.
That said I could have just added a keyable property… I just replaced it with a functionally equivalent test

When would it not be set here?

If the fiber is a HostResource but the props preclude getting a resource the memoized state will be null. Imagine you update a style sheet to not have a precedence or something. The old resource is released and no new resource is acquired

I could also have it retain the old state if no new resource was found but that felt wrong to me

Hm... We flip the order? That's unfortunate.

More an artifact of the fact that I did not maintain slots so there was some churn. We could add a little more overhead and track the last meta to insert after rather than insert after the parent instance. How big a deal is this? I assume none given its a client update and so none of this really matter

Right. It probably doesn't matter.

You can use getElementsByTagName in this case.

Probably leftover for when I was removing the title nodes and needed a static list. I’ll change

Why .item(0) instead of [0] like you do above?
There was a problem hiding this comment.
Item returns null when index overflowing and array notation returns undefined. The insertBefore api technically requires a Node or null though I suspect it would also work with undefined. But I figured it was better to be technically correct

One possible idea is to generate a query similar to what you do for acquireStyleResource but generate it in getResource and you use that as the key.
So the key you use for the map is the selector. That way it's reusable for many resources. You could do parentKey + ',' + childKey to find both.
I'm a little concerned about this being n * n traversals for number of meta tags which can be quite a lot since this runs for every meta tag. Not sure a more specific query selector helps though.

This PR adds meta tags as a resource type.
metas are classified in the following priority
when using property, there is special logic for og type properties where a
property="og:image:height"following aproperty="og:image"will inherit the key of the previous tag. this relies on timing effects to stay consistent so when mounting new metas it is important that if structured properties are being used all members of a structure mount together. This is similarly true for arrays where the implicit sequential order defines the array structure. if you need an array you need to mount all array members in the same pass.
