As of today, we have published a new cross-platform tool Windows / macOS / Linux: VonkLoader.
The VonkLoader is a free command line, multi-threaded tool to bulk load resources into Vonk. Although the name suggests otherwise, you can use this tool to populate any FHIR server.
Try it out! Sign in to Simplifier.net and find the instructions on the download page. But remember: don’t flood the public test servers that are so kindly hosted by the reference implementers
