Restful communication brought to you by Predix. Px-datasource is a simple wrapper (Angular module and factory) around Restangular.
Add predix.datasource as a dependency to your Angular app.
var predixApp = angular.module('myApp', [
'predix.datasource'
...
]);
You now have full access to Restangular functionality; just replace "Restangular" in the Restangular docs with PxDatasource.
