What is the FHIR Bundle Composer?

Most FHIR servers expose a Patient/$everything operation that returns a Bundle containing a root Patient plus every related clinical resource — Observations, Conditions, Immunizations, MedicationRequests, and friends. Building one of those Bundles by hand is fiddly: every related entry must reference the root Patient via the right field (subject vs patient), every entry needs afullUrl, and for a transaction Bundle each entry needs an HTTPrequest. The Composer does all of that for you.

What it does

Pick a root Patient (paste, generate synthetic, or browse samples).
Add related resource groups with a chosen variant and a count.
Watch the Bundle assemble live with references resolved internally.
Switch between transaction / batch / collection / document / searchset shapes.
Send the result straight to the Bundle Visualizer, Validator, or Diff.
