  const viewElement = document.querySelector("arcgis-map");
  const arcgisSwipe = document.querySelector("arcgis-swipe");

  const layer1 = new TileLayer({ url: "..." });
  const layer2 = new TileLayer({ url: "..." });

  viewElement.map = new Map({
    basemap: "satellite",
    layers: [layer1, layer2],

Routing (Programmatic)

Basic Route

javascript
import * as route from "@arcgis/core/rest/route.js";
import RouteParameters from "@arcgis/core/rest/support/RouteParameters.js";
import FeatureSet from "@arcgis/core/rest/support/FeatureSet.js";

    symbol: {
      type: "simple-marker",
      style: "cross",
      size: 15,
    },
  });
  routeLayer.add(stop);
  routeParams.stops.features.push(stop);

  if (routeParams.stops.features.length >= 2) {
    const result = await route.solve(routeUrl, routeParams);
    const routeResult = result.routeResults[0].route;
    routeResult.symbol = {
      type: "simple-line",
      color: [0, 0, 255, 0.5],

  returnDirections: true,
  directionsLanguage: "en",
  returnRoutes: true,
  returnStops: true,
  impedanceAttribute: "TravelTime",
  outSpatialReference: { wkid: 4326 },
});

const result = await route.solve(routeUrl, routeParams);

directions.features.forEach((feature) => {
  console.log(feature.attributes.text);
});

Print

Print Component

html
<arcgis-map item-id="YOUR_WEBMAP_ID">
  <arcgis-expand slot="top-right" expand-tooltip="Print">
    <arcgis-print></arcgis-print>
  </arcgis-expand>
</arcgis-map>

Print Widget (Core API)

javascript
import Print from "@arcgis/core/widgets/Print.js";

const print = new Print({
  view: view,
  printServiceUrl:
    "https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task",
  allowedFormats: ["pdf", "png32", "jpg"],
  allowedLayouts: ["a4-landscape", "a4-portrait", "letter-ansi-a-landscape"],
  templateOptions: {
    title: "Default Map Title",
    author: "Default Author",
  },
});

view.ui.add(print, "top-right");

Print Service (Programmatic)

javascript
import * as print from "@arcgis/core/rest/print.js";
import PrintTemplate from "@arcgis/core/rest/support/PrintTemplate.js";
import PrintParameters from "@arcgis/core/rest/support/PrintParameters.js";

const printUrl =
  "https://utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task";

const template = new PrintTemplate({
  format: "pdf", // pdf, png32, png8, jpg, gif, eps, svg, svgz
  layout: "a4-landscape", // Or custom layout name
  exportOptions: { dpi: 300 },
  layoutOptions: {
    titleText: "My Map",
    authorText: "Author Name",
    copyrightText: "Copyright 2025",
    scalebarUnit: "Kilometers",
  },
});

const params = new PrintParameters({
  view: view,
  template: template,
});

const result = await print.execute(printUrl, params);
console.log("PDF URL:", result.url);

Print Formats

FormatDescription
pdfAdobe PDF
png32PNG with transparency (32-bit)
png8PNG 8-bit
jpgJPEG
gifGIF
epsEncapsulated PostScript
svgScalable Vector Graphics
svgzCompressed SVG

Map-Only Export (No Layout)

javascript
const template = new PrintTemplate({
  format: "png32",
  layout: "map-only",
  exportOptions: {
    width: 1920,
    height: 1080,
    dpi: 96,
  },
});

Screenshot as Alternative

For quick exports without a print service:

javascript
const screenshot = await view.takeScreenshot({
  format: "png",
  width: 1920,
  height: 1080,
  quality: 90,
});

// Download
const link = document.createElement("a");
link.download = "map-screenshot.png";
link.href = screenshot.dataUrl;
link.click();

Elevation Profile

Elevation Profile Component

html
<arcgis-scene>
  <arcgis-elevation-profile slot="top-right"></arcgis-elevation-profile>
</arcgis-scene>

Elevation Profile Widget (Core API)

javascript
import ElevationProfile from "@arcgis/core/widgets/ElevationProfile.js";

const elevationProfile = new ElevationProfile({
  view: view,
  profiles: [{ type: "ground" }, { type: "view" }],
});

view.ui.add(elevationProfile, "top-right");

Identify

Identify on MapImageLayer

javascript
import * as identify from "@arcgis/core/rest/identify.js";
import IdentifyParameters from "@arcgis/core/rest/support/IdentifyParameters.js";

const identifyURL =
  "https://sampleserver6.arcgisonline.com/arcgis/rest/services/MtBaldy_BaseMap/MapServer";

const params = new IdentifyParameters({
  tolerance: 3,
  layerIds: [0, 1, 2, 3, 4],
  layerOption: "top", // "top", "visible", "all"
  width: view.width,
  height: view.height,
});

view.on("click", async (event) => {
  params.geometry = event.mapPoint;
  params.mapExtent = view.extent;

  const response = await identify.identify(identifyURL, params);

  const features = response.results.map((result) => {
    const feature = result.feature;
    feature.attributes.layerName = result.layerName;
    feature.popupTemplate = {
      title: result.layerName,
      content: "{*}",
    };
    return feature;
  });

  if (features.length > 0) {
    view.openPopup({
      features: features,
      location: event.mapPoint,
    });
  }
});

Find

Find Service

javascript
import * as find from "@arcgis/core/rest/find.js";
import FindParameters from "@arcgis/core/rest/support/FindParameters.js";

const findUrl =
  "https://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer";

const params = new FindParameters({
  searchText: "California",
  layerIds: [0, 1, 2],
  searchFields: ["STATE_NAME", "NAME"],
  returnGeometry: true,
});

const result = await find.find(findUrl, params);

result.results.forEach((r) => {
  console.log(r.feature.attributes);
});

Reference Samples

  • widgets-measurement - Distance and area measurement tools
  • widgets-measurement-3d - 3D measurement tools
  • widgets-print - Print widget for map export
  • widgets-directions - Directions widget for routing
  • swipe - Swipe widget for comparing layers
  • coordinate-conversion - Coordinate conversion utility
  • bookmarks - Bookmarks navigation
  • elevation-profile - Elevation profile widget

Common Pitfalls

  1. API Key for routing: Route service requires a valid API key or authenticated user.
  1. Identify tolerance: Set appropriate tolerance based on zoom level. Low tolerance at high zoom levels may miss features.
  1. Swipe layer order: Leading/trailing layers must be in the map's layers collection before assigning them to the swipe widget.
  1. Measurement units: Use different measurement widgets for 2D and 3D views. The unified Measurement widget auto-selects based on view.type.
  1. Print service URL: The default Esri print service URL may require authentication. Custom print services need their own URLs configured.
  1. Coordinate Conversion inside map: Must be placed as a child of <arcgis-map> with a slot, or use reference-element when outside.

taste

Creative-direction layer for music videos and short-form edits in the angelcore / cloud-trance / hyperpop family — a named-genre aesthetic vocabulary, mood + color + light system, beat-synced editing grammar, and a pipeline chaining ECC's video skills from b-roll generation to distribution. Use when a video must feel intentional rather than merely functional — music videos, fancams, moodboard-driven reels, or giving AI-generated b-roll a coherent visual direction.
