ScaleRangeSlider

AMD: require(["esri/widgets/ScaleRangeSlider"], (ScaleRangeSlider) => { /* code goes here */ });
ESM: import ScaleRangeSlider from "@arcgis/core/widgets/ScaleRangeSlider.js";
Class: esri/widgets/ScaleRangeSlider
Inheritance: ScaleRangeSlider Widget Accessor
Since: ArcGIS Maps SDK for JavaScript 4.13

The ScaleRangeSlider widget allows the user to set a minimum and maximum scale based on named scale ranges. When a layer is provided to the widget, the minScale and maxScale are set to the scale range of the layer.

The user can update the scale range by dragging thumbs across the slider to update the minScale and maxScale. The user can also change the minScale and maxScale by using the dropdowns underneath the minScaleLimit and maxScaleLimit. The thumbnail shows a preview of the scale based on the region specified.

Example
const scaleRangeSlider = new ScaleRangeSlider({
  view: view,
  layer: featureLayer,  // scale range of this layer sets initial minScale and maxScale
  region: "MX",  // preview thumbnail will be of Mexico
});
view.ui.add(scaleRangeSlider, "bottom-left");

// to update the layer min/max scale based on the slider
scaleRangeSlider.watch(["minScale", "maxScale"], function(value, oldValue, name) {
  featureLayer[name] = value;
});
