EsriGeometryPoint Clustering without WGS84 and web mercator

[kenlam]

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,

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

I use a rare WKID 2326

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.
