Topic: cliet-js with resolveReferences

@Vladimir Ignatov at http://docs.smarthealthit.org/client-js/client I'm seeing some examples that look like they're missing curly braces, like:

client.request(
    "Encounter/518a522a-4b10-47db-9daf-53b726d32607",
    resolveReferences: [ "serviceProvider" ]
);

--- when I add curly braces in my own invocations like

        smart.patient
          .request("Observation?code=4548-4&_sort:desc=date&_count=10", {
          resolveReferences: ["entry.resource.subject"]
        })

nothing seems to happen -- am I using this feature incorrectly? (I was expecting to see the library make an extra query to resolve Observation.subject and mount it in place.)

Vladimir Ignatov (Jun 04 2021 at 17:21):

Thanks for pointing that out. I will fix the docs and add the curly braces. Otherwise, does it work with ["subject"] instead of ["entry.resource.subject"]?

Josh Mandel (Jun 04 2021 at 18:26):

Yes, ["subject"] works, thanks! I couldn't predict this from the docs, though. Docs also refer to context and {Response}.context., which I couldn't understand @Vladimir Ignatov (I'd propose different language but I'm unsure of the intent.)

Vladimir Ignatov (Jun 04 2021 at 19:37):

Right, mixing real things like serviceProvider with imaginary ones like context or Response is a poor choice of words. The intent was say that:

The path is relative to the current resource ( subject instead of entry.resource.subject)
The path can have arbitrary depth but should exclude the last reference segment (a.b.c resolves {current resource}.a.b.c.reference but mounts at {current resource}.a.b.c)

Awesome -- that's much clearer! Thanks.
