@nyxapi/devtools

Cache diagnostics for NyxAPI.

import { createInspector } from "@nyxapi/devtools";

const inspector = createInspector(nyx.queryClient, {
  redact: (key, data) => data, // decide what `inspectData` may reveal
});
inspector.subscribe(() => console.log(inspector.snapshot().queries));

• snapshot() is referentially stable until something changes, so it works with useSyncExternalStore. It lists query state, observer counts, errors (name and message) and a bounded event log. It never contains cached data.
• inspectData(hash) returns one entry's data through redact.
• refetch, invalidate, remove act on one entry. dispose() stops listening.

React panel (requires @nyxapi/react):

import { NyxDevtools } from "@nyxapi/devtools/react";

<NyxDevtools defaultOpen />; // client from <NyxProvider>, or pass `client`

It renders nothing when process.env.NODE_ENV === "production" unless force is set. Not yet available: a per-request timeline.
