Optimize ArcGIS Maps SDK for JavaScript applications for speed, memory, and bundle size. Use for improving map initialization, data loading, query efficiency, large dataset handling, and view rendering performance.
Configure rich popup content with text, fields, media, charts, attachments, and related records. Use when customizing feature popups, adding charts or images to popups, templating popup titles and field formatting, or displaying related record data on click.
Manage portal content including saving WebMaps/WebScenes, bookmarks, slides, and portal items. Use for content persistence, WebMap/WebScene configuration, and navigation presets.
Call ArcGIS REST service endpoints for routing, geocoding, printing, places, geoprocessing, and other server-side operations. Use when computing directions or service areas, converting addresses to coordinates, exporting print-ready maps, searching for places, or invoking GP tools.
Configure SceneView environment settings including lighting, weather, shadows, atmosphere, backgrounds, and underground navigation. Use for realistic 3D visualizations.
Auto-generate renderers, calculate statistics, and create data-driven visualizations. Use for class breaks, unique values, heatmaps, dot density, relationship maps, and getting histogram/summary statistics.
Perform spatial analysis using analysis objects, REST services for routing/geocoding/geoprocessing, and feature reduction with clustering/binning. Use when running viewshed, line-of-sight, buffer, or geoprocessing analysis, and when clustering or binning dense point data for visualization.
Scaffold ArcGIS Maps SDK applications with TypeScript and Vite. Includes both a minimal quick-start setup and a production-ready configuration with ESLint, Prettier, git hooks, and GitHub Actions CI/CD.
Configure FeatureTable for tabular data display and FormTemplate with input elements for feature editing forms. Use when adding spreadsheet-style data grids, building attribute edit forms, configuring form input types and validation, or surfacing related records in forms.
Work with temporal data using TimeSlider, TimeExtent, TimeInterval, and time-aware layers. Use for animating data over time, filtering by date ranges, and visualizing temporal patterns.
Work with ArcGIS Utility Networks for modeling and analyzing connected infrastructure including network tracing, associations visualization, and topology validation. Use for electric, gas, water, and telecom network analysis.
Style and render geographic data with renderers, symbols, and visual variables. Use for creating thematic maps, heatmaps, class breaks, unique values, labels, and 3D visualization.
Add specialized widgets including BuildingExplorer, FloorFilter, Track, Locate, HistogramRangeSlider, ScaleBar, Compass, NavigationToggle, and media viewers. Use for building exploration, indoor mapping, GPS tracking, and data histograms.
Build map user interfaces with ArcGIS widgets, Map Components, and Calcite Design System. Use for adding legends, layer lists, search, tables, time sliders, and custom UI layouts.
