Firehose phase 4: active relay-health prober (unfreezes /relays)#16
Merged
Conversation
Refreshes the relays directory the /relays page renders (currently a frozen 2025-11 snapshot). Active, kind-less — not a hose. - src/prober.js: dials every relay in the directory (Node global WebSocket) for online/responseTime, fetches the NIP-11 info doc (global fetch) for requiresAuth/requiresPayment, and rolls up uptime via an aggregation- pipeline updateOne so uptime = checksOnline/checksTotal*100 stays consistent with the $inc'd totals. Self-schedules (PROBE_INTERVAL, default 1h); --once / RUN_ONCE for a single sweep. Concurrency + timeout env/CLI configurable. Relay universe = the relays collection, self-fed by the hose URL harvesting. No new deps. - probe.js: pm2/standalone entry (mirrors serve.js); npm run probe. - .env.example + README: document the prober. - test/prober.test.js: pure helpers (config/flags, nip11Flags, relayInfoUrl). Smoke (2 real sweeps): uptime rollup correct, NIP-11 detected a paid relay, offline relays handled, lastChecked set. npm test 55/55. Closes #15

Closes #15. Phase 4 — the active relay-health prober that refreshes the
relaysdirectory the/relayspage renders (currently a frozen 2025-11 snapshot). It's active (dials each relay) and kind-less, so it's not a hose — a self-scheduling module of its own.What
