NDK cache adapter using a nostr relay as the database.
This cache adapter is meant to be run against a local relay. This adapter will generate two NDK instances:
ndk – This talks exclusively to the local relay, with outbox model disabled.
fallbackNdk – This is used to hydrate the cache and uses the outbox model – each query the cache receives is placed in a queue in the background so that subsequent requests can be served from the cache. All events from other relays
npm add @nostr-dev-kit/ndk-cache-nostr
import NDKCacheAdapterNostr from "@nostr-dev-kit/ndk-cache-nostr";
const cacheAdapter = new NDKCacheAdapterNostr({
relayUrl: 'ws://localhost:5577',
});
const ndk = new NDK({ cacheAdapter });
If running server-side in a NodeJS environment, you should make sure to polyfill WebSocket.
