Is it possible to access collection-level properties from buildTileUrlTemplate?

[hrodmn]

I have a collection with render extension properties that can be used to parameterize a titiler tile request URL and I want to rig up buildTileUrlTemplate to find those parameters if they exist and apply them to the tiles that get rendered in the preview map in the Item view.

Is it possible for stac-browser to pass the entire context of an asset to buildTileUrlTemplate? After a little digging I have observed that the Item view just passes the asset JSON (which does not contain any context) to stacLayer, but the buildTileUrlTemplate could take a stac argument that has more context capabilities.

https://github.com/stac-utils/stac-layer/blob/f2582109b09e5057a4211c0525969d9400c2007c/src/add.js#L67-L75

Maybe there is a way to modify the Item view to pass a classed object rather than just the JSON?

Not yet, but it will be possible in v3.4.0 once the migration to ol-stac and stac-js is merged, see #535
You can start using this branch if you want and check whether it works for you.

Docs for stac-js: https://m-mohr.github.io/stac-js/latest/

You should be given a stac-js object and if it's an asset, you can use getContext() to get the Item/Collection. Note, you can get the collection-level properties from within an Item as of now.
