TypeScript types are bundled; the default import is the constructor class.

import LRUCache from 'lru-native2'

Shows instantiation with options, set/get, size, remove, clear, and stats.

import LRUCache from 'lru-native2'; const cache = new LRUCache({ maxElements: 1000, maxAge: 60000 }); cache.set('key1', 'value1'); cache.set('key2', 'value2'); console.log(cache.get('key1')); // 'value1' console.log(cache.size()); // 2 cache.remove('key2'); console.log(cache.get('key2')); // undefined cache.clear(); console.log(cache.size()); // 0 const stats = cache.stats(); console.log('Stats:', stats);
