summary

Shows a working realtime GeoJSON pipeline that uses Server-Sent Events via the browser EventSource API to stream GeoJSON features as plain text and JSON. Uses Node to emit an eventstream, curl to inspect it, and Leaflet to render markers; the stream replays the current set as add/change/remove events so markers appear, update position, and are removed. Implementation is simple, debuggable, and runs in modern browsers (polyfills cover older ones).
