Consuming the event stream

const es = new EventSource('https://floo-explorer.btlabs.uk/events');
es.addEventListener('tip', (e) => {
  const s = JSON.parse(e.data);
  console.log(s.chain.nodeHeight, s.latest[0].hash);
});
es.addEventListener('reorg', (e) => console.warn('reorg', JSON.parse(e.data)));

A tip event carries the same object as /api/summary. Events fire on each snapshot rebuild, which happens when a block arrives and every few seconds for peer and mempool changes — so treat it as "current state", not as a per-block log.
