Is it possible to access properties from a custom config file (props.conf) in a Simple XML extension?

[kbarker302]

I would like to access properties from a custom config file in a Simple XML extension - is this possible? For now, I am just trying to access the props.conf from the default search app using the following code, which is based on the SplunkJS SDK documentation:

var files = svc.configurations( 
{    
  app: "search",
  owner: "admin"
});

files.item("props", function(err, propsFile) {
    propsFile.fetch(function(err, props) {
    console.log(props.properties()); 
  });
}); 

However, I am unsure how to instantiate the svc (splunkjs.Service) object for a Simple XML extension. I have tried instantiating it like this:

var http = new splunkjs.ProxyHttp("/proxy");
var svc = new splunkjs.Service(http, {
    username: "admin",
    password: "changeme",
    scheme: "https",
    host: "localhost",
    port:"8089",
    version:"6.3.0"
});

and it does give me a configurations object, but the result is always null.

Any help would be greatly appreciated.

For the record, I was able to accomplish what I wanted using the following code:

require([
    "splunkjs/mvc",
    "splunkjs/mvc/simplexml/ready!"
], function(
 mvc
) {
    mvc.createService().get("/servicesNS/-/search/configs/conf-props",{},function(err,response) {
        content=response.data.entry[0].content;
    }); 
}); 

This returns a content object that contains the properties I was looking for, which can be queried as necessary.

H/T to the following code on GitHub - the _get_api_key function posted there got me pointed in the right direction:
