Readme
FHIR-Graph
This is the folder for the fhir-graph npm package. This package is for reading FHIR files and generate a chart data for those FHIR files.
Features
It allows you to read FHIR json files in a folder, sort them by issued date, and generate the char data of date and value. Then you can easily show it by using chart.js.
How to download:
Use "npm install fhir-graph" or specify "fhir-graph" : "~1.1.1" (the current lastest version) in your node package.json dependencies.
How to use:
After finishing download, put the folder that contains all your FHIR files into the node_modules/fhir_graph/fhir_files. For examples, put folder "steps" that contains 6 fhir files (they must be json files) into yourProjectName/node_modules/fhir_graph/fhir_files/.
Then in your code (probably in your route js), use it like that:
var FHIR_Graph = require('fhir-graph');
var fhir_foldername = 'steps';
FHIR_Graph.show_FHIR_Graph(fhir_foldername, function(err, data) {
if (err) throw err;
var fhir_data = data;
res.render('home.ejs', {
fhir_data : fhir_data,
path : 'dashboard.ejs',
title : 'Dashboard'
});
});
You must use a call back to get the data because it's synchronized.
Then just use the "fhir_data" in your ejs file like that:
<script src="/chartjs/js/vendor/modernizr-2.8.3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.5.0/Chart.min.js"></script>
<div class="col-md-4">
<div class="card">
<div class="content">
<canvas id="stepsMonth" height="335"></canvas>
<script>
const STEPSMONTH = document.getElementById("stepsMonth");
Chart.defaults.scale.ticks.beginAtZero = true;
var stepsMonth = new Chart(STEPSMONTH, <%- JSON.stringify(testFhir) %>);
</script>
</div>
</div>
</div>
Then you can see the graph from the page you specified:
