High-performance TypeScript LRU (Least Recently Used) cache with TTL expiration & zero dependencies.

Fast in-memory LRU cache storing key-value pairs with automatic eviction of least recently used items when maximum size capacity is reached.

🚀 Features

• ⚡ O(1) Access: Ultra-fast Map-based LRU eviction strategy.
• ⏳ TTL Support: Time-To-Live expiration per cache instance or per item.
• 🛡️ Type-Safe: Full TypeScript generics support (LRUCache<Key, Value>).

📦 Installation

npm install @febin52/cache-lru-ts

💡 Usage

import { LRUCache } from '@febin52/cache-lru-ts';

// Max capacity of 500 items, 60s default TTL
const cache = new LRUCache<string, { name: string }>({ max: 500, ttl: 60000 });

cache.set('user:100', { name: 'Alice' });
cache.get('user:100'); // { name: 'Alice' }
cache.has('user:100'); // true
cache.size; // 1
cache.clear();
