Quick Decision Guides

Map Components vs Core API

Question	Map Components	Core API
Starting a new project?	Preferred	Only if you need low-level control
Need slot-based widget placement?	Yes, built-in	No, use `view.ui.add()`
Using a framework (React/Angular)?	Works as custom elements	Works, but more boilerplate
Need programmatic map creation?	Possible via JS properties	Native approach
CSS setup?	Automatic (npm)	Requires `main.css` import
Migrating legacy code?	May need refactoring	Existing code works

Default choice: Map Components (<arcgis-map>, <arcgis-scene>). Fall back to Core API only when you need direct MapView/SceneView constructor control or are maintaining existing Core API code.

Layer Type Selection

Your data source	Layer to use
ArcGIS Feature Service	`FeatureLayer`
GeoJSON file/URL	`GeoJSONLayer`
CSV with coordinates	`CSVLayer`
Cached map tiles	`TileLayer`
Vector tiles	`VectorTileLayer`
3D buildings/objects	`SceneLayer`
Photogrammetry mesh	`IntegratedMeshLayer`
LiDAR point cloud	`PointCloudLayer`
Client-side graphics	`GraphicsLayer`
Raster imagery	`ImageryTileLayer`
WMS/WFS/OGC	See `arcgis-advanced-layers`
Parquet file	`ParquetLayer`
Real-time stream	`StreamLayer`

Authentication Approach

Scenario	Approach	Skill
Public app with basemaps/geocoding	API key via `esriConfig.apiKey`	`arcgis-authentication`
App that accesses user-specific content	OAuth 2.0 with `OAuthInfo`	`arcgis-authentication`
Enterprise portal behind firewall	OAuth 2.0 with custom `portalUrl`	`arcgis-authentication`
Server-to-server (no user)	App token (client credentials)	`arcgis-rest-services`
Quick prototype / demo	API key	`arcgis-authentication`
