Diagnostics | nostrbase docs

Inspect the log

const db = createClient({
  namespace: "my-app",
  relays,
  diagnostics: { capacity: 200, onEntry: entry => console.log(entry) },
});
const entries = db.diagnostics.list();
const listener = db.diagnostics.events$.subscribe(entry => console.log(entry));
db.diagnostics.clear();
listener.unsubscribe();

The buffer keeps up to capacity entries, from 1 to 10,000. Set enabled: false to disable it. SDK entries contain request counts, event IDs/kinds, acknowledgement counts, error codes, and passive connection state. They exclude record bodies, decrypted private data, secret keys, and auth tokens. Your callbacks must decide what they save. This is local diagnostics, not hosted logs.
