Real Time GeoJSON APIs
summary
Describes a working realtime API that streams GeoJSON features over plain HTTP using Server-Sent Events and the browser EventSource DOM API, emitting add/change/remove events so the client can treat buses as enter/update/exit. Implementation uses Node to emit the SSE stream, curl to inspect it, Leaflet + browserify to plot points, and optional Google Street View to render a driver simulator. The server replays current state as add events, then sends periodic change events; markers move on the map and reconnection is automatic.
