Hello esri community, the reference "extras/ClusterLayer" that's mentioned on this sample https://developers.arcgis.com/javascript/3/sandbox/sandbox.html?sample=layers_point_clustering comes with ArcGis JavaScript version 3.11? I can't see any "extras" reference on JavaScript API reference page. Thanks for the help.
"Extras" is a directory where the script "ClusterLayer.js" is found. If you download the source code from its sample page, you'll see how the directory structure for the project is set up. The location of this directory is set in the dojoConfig portion of the index.html. You can read up more about how to configure the paths or packages here: Configuring Dojo with dojoConfig - Dojo Toolkit Tutorial
I've to download the sample and use that .js inside of the .zip or there's a pack or something like that to download? You know if it has compatibility with v3.11?
You can find this on ESRI's github as well: https://github.com/Esri/cluster-layer-js
