KVS — @coderbuzz/kvs

Multi-backend key-value store for TypeScript. Embed directly in your app — zero HTTP deps. Supports SQLite (sync) and PostgreSQL (async).

Atomic transactions, TTL expiry, persistent queue with retries, real-time watch, and push-based listeners.

Installation

npm install @coderbuzz/kvs

Quick Start

import { KVStore, AsyncKVStore } from "@coderbuzz/kvs";

// Sync — SQLite (bun:sqlite)
const store = new KVStore("kv.db");
store.set(["greeting"], "hello world");
console.log(store.get(["greeting"])?.value);

// Atomic counters
const views = store.increment(["page", "views"]);
store.increment(["page", "views"], 5); // custom delta

// Queue with auto-retry
store.enqueue({ task: "send-email" }, { topic: "mailer", maxAttempts: 3 });
store.addQueueListener("mailer", (msg) => {
  processTask(msg.payload);
  store.acknowledge(msg.id);
});

// Async — SQLite or PostgreSQL (bun:sql)
const asyncStore = new AsyncKVStore("sqlite://kv.db");
await asyncStore.set(["greeting"], "hello world");
console.log(await asyncStore.get(["greeting"]));

// PostgreSQL
const pgStore = new AsyncKVStore("postgres://user:pass@localhost:5432/kvdb");
await pgStore.set(["key"], "value");
