Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

JS

              
                // NOTE - This is fixed in JS API 4.14! 
// https://codepen.io/gavinr/pen/poveRGE
// Example of how to use the "fullExtent" property on a KML layer in ArcGIS JS API 4.13. 
// It seems like right now the fullExtent is not what you would expect it to be --
//
// In this example it should be zooming to the features located in Illinois, USA
// but instead it is zooming to the entire map.
//
// This might be changed in the future, but for now (2019-08) two workarounds include:
// 
// 1. Write some code to query the layerView to get the extent:
//    https://codepen.io/gavinr/pen/YzKNpxj?editors=0010
//    -- or -- 
// 2. Call the utility service again and use the "lookAtExtent" property:
