Hi there,  Do you have data with two date fields like opening and close dates? If so then you can filter your data based on the closing dates whenever timeSlider.timeExtent changes as shown below:  timeSlider.watch("timeExtent", () => { const closedDate = timeSlider.timeExtent.start.getTime(); const where = `perimeterdatetime = ${closedDate}`; layerView.filter = new FeatureFilter({ where }); }); The following demo app shows how it can be done. Here is the live app:https://ubatsukh.github.io/arcgis-js-api-demos/devsummit2021/fire-perimeter/ Here is the code: https://github.com/ubatsukh/arcgis-js-api-demos/tree/master/devsummit2021/fire-perimeter   Hope this helps ...

Hi there,  You could listen to the pointer-up event on the timeSlider div to achieve what you are trying to do. Here is a codepen showing how it is done. https://codepen.io/U_B_U/pen/abMJdaL?editors=1000 The following is the how you can do it.    document.getElementById("timeSlider").addEventListener("pointerup",(event) => { console.log("here is your time extent", timeSlider.timeExtent); });     You could also debounce when watching timeExtent using  the debounce function technique mentioned in this article: JavaScript Debounce Function (davidwalsh.name)   Hope this helps, -Undral ...

Hi there,  Please check out this post as it discusses about adding button to popupTemplate. I have updated the app to work with 4.28: https://codepen.io/U_B_U/pen/KKENPpZ?editors=1000   ... View more

WebTileLayer's spatialReference is 102100. Looks like you are working with WMTS service (https://wmts.nlsc.gov.tw/97/wmts/). So I would add the layer as WMTSLayer as shown below.    const layer = new WMTSLayer({ url: "https://wmts.nlsc.gov.tw/97/wmts" extent: { xmin: 128548.4443375419, ymin: 2394066.4166165744, xmax: 606875.5521, ymax: 2919551.2968000006, spatialReference: { wkid: 3826 } } }); const map = new Map({ layers: [layer] }); const view = new MapView({ container: "viewDiv", map: map, spatialReference: { wkid: 3826 }, });   ...

Hi there,  You need to specify the spatialReference for the view's extent as the following:  var view = new MapView({ container: "divmap", map: map, zoom: 3, extent: { xmin: 296938.73458000005, ymin: 2776832.77203, xmax: 301876.2566600001, ymax: 2781271.34259, spatialReference: { wkid: 102443 } }, crossOrigin: 'anonymous', spatialReference: { wkid: 102443 } }); ...

Hi there,  Ah yes this is a known issue at 4.28. This issue will be addressed in 4.29 and the fix is already in `next`. You can update your codepen to point to  <script src="https://js.arcgis.com/next/"></script> to check the fix.  Hope this helps, ... View more

You are getting this error likely because the field you are running the query on does not exist on the layer or the layer view. Try setting the FeatureLayer.outFields property to include the fields you want to work with.  ... View more

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
