Hi there,  Please take a look at the Add an array for client-side features topic to see the requirements for creating a client side stream layer. In this section, the following is pointed out:  Geometries of features added to the StreamLayer must be in the spatial reference of the view, because the layer's spatialReference is always set to the spatial reference of the view. To avoid overhead, the stream layer does not do any additional processing or reprojecting on features as they arrive. Based on this statement, you either need to change the basemap of the map to be in WGS 84 or the StreamLayer projection to match the view's spatialReference.  In any case, I updated your app to make couple of changes: https://codepen.io/U_B_U/pen/oNmMoyy?editors=1000 1. First I updated the baseman to be WGS84 basemap 2. Then I updated the geometry of the feature you are adding to use x and y coordinates instead of latitude and longitude.  You can see these updates in the codepen I provided above. ... View more

Hi there,  I think you are asking if a GeoJSONLayer can be persisted in a webmap. It can and this support was added at version 4.22 - https://developers.arcgis.com/javascript/latest/4.22/#better-support-for-csvlayer-and-geojsonlayer   ... View more

Hi there,  That is because the API fetches all of point features at once from the server. Once loaded, the features won't need to be re-requested from the server, which will make future redraws after panning and zooming much faster. This is the release note: https://developers.arcgis.com/javascript/latest/4.19/#performance-improvements If you need to disable this behavior for some reason then you can read how from this post: https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/arcgis-4-2x-now-much-slower-to-fetch-and-draw/m-p/1136698/highlight/true#M76067   ...
