Topic: Multiple FHIR servers with JavaScript client?
Paul Lynch (Aug 28 2019 at 18:48):
I understand from a previous thread that a SMART app can talk to multiple FHIR servers. Can the JavaScript client at https://docs.smarthealthit.org/clients/javascript/ be used to do that? I don't see a way to indicate which FHIR server one means when calling the "authorize" or "ready" functions.

First off, a shout out to Vlad's updated library ("v2"), docs at http://docs.smarthealthit.org/client-js/ (Note @Vladimir Ignatov we should update docs at https://docs.smarthealthit.org/clients/javascript/ now that things are stabilizing.)

When it comes to authorizing, you can specify a fhirServiceUrl as a parameter to authorize (see https://github.com/smart-on-fhir/client-js/blob/master/src/smart.js#L113-L127)
Josh Mandel (Aug 29 2019 at 17:18):
That lets you specify which server you mean.

When it comes to calling ready, this should be driven by the state value returned from your OAuth server, so there ought not be any ambiguity about where to exchange a token.

Hope this helps -- and please let us know how this goes; it'd be good to document this kind of "advanced flow" more directly, if you find it useful (and to work through any issues if you find it breaks ;-)).

Thanks! We're still in the planning stages for a brand-new idea for a small project, so it might be a while before we try it out, but I am encouraged that you think it should work.
