I am trying to use this GitHub - odoe/esri-clusterfeaturelayer: Based on the Esri ClusterLayer, but similar to FeatureLayers.
but I have no success.
Does it require a feature service?
It looks like it does
Look here too:
No more errors but not showing me clusters.
I have got this strange proxy issue:
esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.
I am not dealing withe external data so not too sure why I would need a proxy.
After some testing, it looks like it does not work great with Map service but works better with feature services.
Retrieving data ...
