Loading an external JS file in splunk

[nadlurinadluri]

I need to load a js from external location (google maps js which Google exposes), instead of storing it in /appserver/static location. Is it possible to do that?

@nadlurinadluri please check out Splunk Custom Visualization API documentation if you need to use external JS for visualization: https://docs.splunk.com/Documentation/Splunk/latest/AdvancedDev/CustomVizTutorial#Create_the_visuali...

One other option would be to convert to HTML dashboard (however, you will lose Simple XML dashboard and several other features and editing dashboard would not be easy unless you are familiar with HTML, JS, CSS and Splunk Web Framework): http://dev.splunk.com/view/SP-CAAAEN6

If this is for GoogleMapView, you can try out Splunk Web Framework with Simple XML JS Extension using SplunkJS view: https://docs.splunk.com/DocumentationStatic/WebFramework/1.1/compref_googlemap.html

If it is plain js file (unlike with async defer options with Google Maps JS), you can also use simple XML JS Extension to directly include the CDN url. For example js with d3 CDN (d3_cdn.js) below which can be used in Dashboard:

require(["jquery", 
         "https://d3js.org/d3.v5.min.js",
         "splunkjs/mvc/simplexml/ready!"], function($, d3) {
    console.log("D3 Script Loaded");
    d3.selectAll("#mydiv p").style("color", "blue");
});

Following is a run anywhere example:

<dashboard script="d3_cdn.js">
  <label>D3 Using CDN</label>
  <row>
    <panel>
      <html>
        <div id="mydiv">
          <p>Some Text here.</p>
          <p>Some Text there.</p>
        </div>
      </html>
    </panel>
  </row>
</dashboard>
