Hi, grateful if there is other clustering sample except for Samples | ArcGIS API for JavaScript 3.22 

As I try to use FeatureReduction for feature layer, it prompts WGS84 message but I am under HK1980 environment.

Would there be any other alternative for EsriGeometryPoint or Feature Layer clustering?

Many thanks

Ken,

   If you are not using WebMercator or WGS84 then you need to use a library like this one:

GitHub - Esri/cluster-layer-js: One example of how to cluster many point features

I have built an app using a  basemap with WKID 102629 and it works fine.

Ken,

   So you are using a custom base map that is in WKID 102140?
