A Developer’s Guide to Open Source Web Mapping Libraries
summary
Compares Leaflet, MapLibre GL JS and OpenLayers with concrete demos: Leaflet for simple points plus many plugins and client clustering; MapLibre as a Mapbox 1.x fork using vector tiles and WebGL with extended zoom (~22); OpenLayers for multi‑projection and WMS imagery. Shows Esri integrations (esri‑leaflet, arcgis rjs), a GitHub repo of runnable samples, the 2,000‑feature server limit for ArcGIS feature layers and the offset/result batching workaround, and converting feature layers to vector tile layers for fast client rendering.
