Features in a feature layer are fetched using the query function on a feature service, which is documented here: ArcGIS REST API  The controller is in charge of determining when to send those queries, besides the first query, which is sent before the controller is instantiated.  The controller watches its extent property and the layer's definition expression for changes, and it sends a new query when a change occurs.  This is why changing the extent property on the controller or changing the definition expression causes new features to be fetched. If you need to set this process up for all feature layers, you might try something like this: view.watch('stationary', isStationary => {   if (isStationary){     view.layerViews.forEach(lv => {       if (lv.layer.type === 'feature'){         lv.controller.extent = view.extent);       }     })   } });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I think that will catch group layers. In general, there's one layerView for each layer.  The layer itself represents the reference to some back-end resource (or sometimes a front-end resource) while the layerView contains logic and information about how the layer is actually displayed in the view. ...

An extent or a rectangle?  The difference is that an extent will always be oriented based on the surface of the world, whereas a rectangle could be oriented however you like. To draw an extent, you can do something simple like this (click and drag to draw): JS Bin - Collaborative JavaScript Debugging  I imagine extents will be added to the drawing tools at some point. ...

In my experience the best way to approach this is to manually add the KML as a portal item using the Add Item option from My Contents and use your browser's dev tools to look at the request that gets sent (chrome has a preserve log option to make sure the network log keeps the request).  You can use this request as a template for what your request has to do. That aside, here's some code I've used to upload to upload files as portal items using esri/request: // user is a portalUser. // fileList is an array of files. // tags is an array of strings function addFileaAsPortalItem(user, fileList, tags){   const file = fileList[0];   let form = new FormData();   form.append('file',file);   form.append("f", "json");   form.append("title", file.name);   form.append("name", file.name);   form.append("type",'KML');   form.append("token", <server token>);   form.append("filename", file.name);   form.append("tags", tags.join());   return esriRequest(`${user.userContentUrl}/addItem`,{     method: 'post',     query: form   }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I'm not sure if this will fail when the file is too large.  I've used it to upload images, kml, text documents, and more.  It also may be a good idea to use esri/request for this, as opposed to the fetch api. ...
