FHIR Chat · JSON in demo website

I was showing the fhirpath.js demo website to our group here, and it was suggested that we have the ability to paste JSON into the demo instead of just YAML. I don't want to remove the YAML, but I will add an option near the top to switch to a JSON entry mode. (An XML entry mode might be nice too, eventually, but that would be for later.)

agree

with xml we have problem - we need converter :)

nicola (RIO/SS) (Sep 13 2018 at 15:55):

There is no xml->json converter in js

nicola (RIO/SS) (Sep 13 2018 at 15:56):

And it's quite a tricky problem - i did it in clojure

I think you mean there is no json->xml converter, right? xml->json could be done with https://www.npmjs.com/package/xml2js. The tricky part about json->xml that I see is not knowing whether to put something in as an attribute or a child element.

Paul Lynch (Sep 13 2018 at 16:55):

So, if someone pasted in a JSON resource, and the switched modes to XML, we probably could not do the correct transformation for them. (But then again, why would they do that?)

with fhir this is more complex, you need metadata to convert from/to json

I got the JSON option working, but I am think we should have some tests for the demo website to make sure it stays working. I am planning to try adding a protractor test for it on Monday.
