"A Developer's Guide to Open Source Web Mapping Libraries"
summary
Demos show Leaflet and MapLibre GL JS plus Esri Leaflet and ArcGIS REST JS, with a working audience map app built and used live. GeoJSON loads 119 bike stations quickly but bogs down with 29,000 trees (about 12 seconds), feature layers stream only the viewable data, and MapLibre with vector tiles serves 95,000 schools responsively while REST JS returns only the first 2,000 features by default. Clustering and geosearch plugins work as shown.
