This project is part of the Keyv suite.
In order to use LRU as your store in Keyv you will need to:
Install this module in your project:
npm install @appigram/keyv-lru
This module is based on the tiny-lru
module. This is one of the best performing libraries for LRU storages.
Create your Keyv object by executing:
```js import { KeyvLru, KeyvLruManagedTtl } from '@appigram/keyv-lru'; const options = { max: 1000, notify: false, ttl: 0, expire: 0, }; const keyvLru = new KeyvLru(options); const keyvLruManagedTtl = new KeyvLruManagedTtl(options); ```See tiny-lru to learn about the
available options.
KeyvLruManagedTtl uses a managed TTL strategy instead of timers. This is useful for serverless architectures. tiny-lru expires entries based on timers, that means that the event loop is not empty when the lambda function is finished. That blocks the end of the execution.
This implementation will store the expiration time along with the cached data
and it will deleter expired items upon retrieval. Alternatively there is an
evictExpired() method that will evict all the expired items.
Even when not using tiny-lru‘s built-in expiration system based on timers, we
still benefit a lot from the LRU store.
