Blue Button CMS to FHIR Parser

Generate FHIR JSON data from CMS files.

This library provides the following functionality

• Parse CMS document
• Generate set of resources conformant to FHIR DSTU2

Usage example:

var split = require('split');
var bbcms = require("cms-fhir");

//open input stream
var istream = fs.createReadStream(__dirname + '/fixtures/sample.txt', 'ascii');

//convert the stream into FHIR model
        istream.pipe(split()) // split into the rows
            .pipe(new bbcms.CmsFile2Object()) // convert into intermediate object format
            // convetr to a fhir bundle, remove a parameter if you don't want a transaction bundle
            .pipe(new bbcms.IntObjToFhirStream("http://localhost:8080/fhir/base")) 
            .on('data', function (data) {
                console.log(JSON.stringify(data, null, '    '));
            })
            .on('finish', function () {
                done();
            })
            .on('error', function (error) {
                done(error);
            });
