@gibme/cache

@gibme/cache

A caching helper that provides a unified interface across multiple cache backends.

Features

• Common async API across all backends (set, get, del, mset, mget, mdel, take, keys, list, clear, ttl)
• Configurable TTL with automatic expiration
• Generic key/value types with JSON serialization
• EventEmitter support for cache events
• Backend systems supported:
  • node-cache (in-memory)
  • redis
  • SQL databases via @gibme/sql (MySQL, MariaDB, PostgreSQL, SQLite)

Requirements

• Node.js >= 22

Installation

npm install @gibme/cache

Usage

Memory

import Memory from '@gibme/cache/memory';

const client = new Memory({ stdTTL: 600 });

await client.set('somekey', { some: 'value' });

const value = await client.get('somekey');

if (value) {
    console.log(value);
}

await client.disconnect();

Redis

Redis configuration can be supplied directly or via environment variables (REDIS_HOST, REDIS_PORT, REDIS_USERNAME, REDIS_PASSWORD).

import Redis from '@gibme/cache/redis';

const client = new Redis({
    host: 'localhost',
    username: 'someuser',
    password: 'somepassword'
});

await client.set('somekey', { some: 'value' });

const value = await client.get('somekey');

if (value) {
    console.log(value);
}

await client.disconnect();

Database

import Database from '@gibme/cache/database';

const client = new Database({
    stdTTL: 600,
    tableName: 'cache'
});

await client.connect();

await client.set('somekey', { some: 'value' });

const value = await client.get('somekey');

if (value) {
    console.log(value);
}

await client.disconnect();

API

All backends implement the same abstract Cache interface:

Method	Description
set(key, value, ttl?)	Store a value with optional TTL (seconds)
get(key)	Retrieve a value
del(key)	Delete a key
includes(key)	Check if a key exists
take(key)	Get a value and delete it in one operation
mset(keys, values, ttl?)	Set multiple key/value pairs
mget(keys)	Get multiple values
mdel(keys)	Delete multiple keys
keys()	List all keys
list()	Get all entries as a Map
clear()	Delete all entries
ttl(key, ttl)	Update a key's TTL
getTtl(key)	Get remaining TTL in seconds
connect()	Establish backend connection
disconnect()	Close backend connection
isReady	Whether the backend is connected
