hypercore-cache
A caching module for Hypercore tree nodes and blocks.
This module mplements the hashlru algorithm internally for LRU caching, but it uses byte length estimates instead of the entry count for eviction.
Installation
npm i hypercore-cache --save
API
const cache = new HypercoreCache(opts = {})
Creates a new cache.
Options can include:
{
maxByteSize: 1e6,
estimateSize: val => { ... },
onEvict: (evicted) => { ... }
}
cache.set(key, value)
Sets key
to value
.
cache.get(key)
Gets the value for key
.
cache.del(key)
Deletes key
from the cache.
const subCache = cache.namespace()
Creates a namespaced sub-cache which mirrors the hypercore-cache API.
This is useful if you want to create a single cache instance that manages resources for multiple hypercores.
