So I'm curious to see if anyone has tested to see how Portal performs as the number of items grow really large. A million anyone, 10 million? As I understand it (correct me if I'm wrong), Portal is backed by a Postgres database for storing item metadata and file items as BLOB's. So it seems to me that Portal should be able to hold a lot of items. Is anyone using Portal as a document management systems of sorts, i.e. storing non-spatial documents related to map features in Portal, that are tagged using a UID of whichever feature they relate to? I could envision a number of useful scenarios. ... View more

I'm continuing my quest to pick up some Typescript and have started to 'translate' some JS examples in the ESRI documentation to Typescript. Oftentimes, that's not really much work. But I'm struggling with the following buffer example that came from here: var bufferLayer = new GraphicsLayer(); var pointLayer = new GraphicsLayer(); map.addMany([bufferLayer, pointLayer]); // [...] var polySym = { type: "simple-fill", // autocasts as new SimpleFillSymbol() color: [140, 140, 222, 0.5], outline: { color: [0, 0, 0, 0.5], width: 2 } }; // [...] function createBuffer(event, view) { // [...] event.stopPropagation(); // convert screen coordinates to map coordinates var point = view.toMap({ x: event.x, y: event.y }); if (point) { bufferPoint(point); } } // [...] function bufferPoint(point) { // [...] clearGraphics(); // removes z values from the point when taken from a SceneView. // GeometryEngine does not support 3D geometries. point.hasZ = false; point.z = undefined; pointLayer.add( new Graphic({ geometry: point, symbol: pointSym }) ); // [...] var buffer = geometryEngine.geodesicBuffer(point, 560, "kilometers"); bufferLayer.add( new Graphic({ geometry: buffer, symbol: polySym }) ); } // [...] function clearGraphics() { pointLayer.removeAll(); bufferLayer.removeAll(); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ My attempt to convert this to Typescript looks like this: let bufferLayer = new GraphicsLayer(); let pointLayer = new GraphicsLayer(); map.addMany([bufferLayer,pointLayer]); function createBuffer(event:any, view:MapView) { event.stopPropagation(); let point = view.toMap({ x: event.x y: event.y }); if (point) { bufferPoint(point); } } function bufferPoint(point:Point) { clearGraphics(); pointLayer.add( new Graphic({ geometry: point, }) ); let buffer = geometryEngine.geodesicBuffer(point, 1, "miles"); let polySym = { type: "simple-fill", // autocasts as new SimpleFillSymbol() color: [140, 140, 222, 0.5], outline: { color: [0, 0, 0, 0.5], width: 2 } }; let bufferLayer.add( new Graphic({ geometry: buffer, symbol: polySym }) ); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This works for the point, which is added to the point graphics layer if I comment out the last section ("let bufferLayer,,,,). But it doesn't work for the buffer. When I try to compile, it screams: So somewhere I must be forgetting to correctly declare the right type ? geometry property appears to be type __esri.GraphicProperties, and buffer __esri.Polygon. The ESRI example was for API v11 ... so has something changed? How do I make this jive? ...
