Can you please try npm install fhir.js? Looks like you may have omitted the ".js" in your attempt here.

(Incredibly confusingly, your command attempted -- and failed -- to install a different library: https://github.com/lantanagroup/FHIR.js)

[kkotak]

Yes! Sorry to bother. That worked! BTW, I'm a bit confused about the various fhir.js variations. I'm new to the HL7 world. If I have an AngularJS/NodeJS framework, what's the best way to use the package? I notice that there are Bower, JQUery, Native, and other packages too.

Thanks.

[jmandel]

Glad to hear that worked.

If you're talking to fhir servers from the frontend, try the Angular adapter or the promise based adapter. If you're talking through a node backend, try the promise based adapter.

For questions, please see http://fhir.org (chat and/or forums).
