Deno KV ​

Deno KV is a flexible key-value store with multiple backends. On Deno Deploy, it is backed by FoundationDB. Locally it is backed by SQLite, and it can also connect to remote databases that follow the KV Connect protocol.

Nostrify offers support for Deno KV with the NDenoKv class. You need the additional @nostrify/denokv package to use it.

WARNING

This feature is in an alpha state and based on an unstable Deno API.

Usage ​

NDenoKv implements NStore, allowing you to use it interchangeably with relays. Just initialize a Deno.Kv instance and pass it to NDenoKv.

ts
import { NDenoKv } from '@nostrify/denokv';

const kv = await Deno.openKv();
const db = new NDenoKv(kv);

Insert an event ​

ts
await db.event(event);

Query events ​

ts
const events = await db.query([{ kinds: [1, 6], limit: 5 }]);

Count events ​

ts
const { count } = await db.count([{ kinds: [1, 6] }]);

Remove events ​

ts
await db.remove([{ kinds: [1, 6] }]);

Keys ​

NDenoKv manages keys prefixed with ["nostr", ...]

It is safe to use the Deno.Kv instance for other purposes as long as keys in the nostr namespace are not overwritten.
