Util suggestion: findResourceById

[Swizec]

Hi,

while building with the Medplum SDK we've developed a few helper methods to help us work with the API. It would be fantastic if some version of these could be added to the official SDK. Making separate issues for more focused discussion :)

We often find ourselves searching a Bundle for a specific resource by ID.

function findResourceById<T extends Resource = Resource>(
    bundle: Bundle<T>,
    id: string
): T | undefined {
    return bundle.entry?.find(
        ({ resource }) => `${resource?.resourceType}/${resource?.id}` === id
    )?.resource as T | undefined
}
