cache-chunk-store

In-memory LRU (least-recently-used) cache for abstract-chunk-store compliant stores

This caches the results of store.get() calls using lru-cache. See the lru-cache docs for the full list of configuration options.

Install

npm install cache-chunk-store

Usage

const CacheChunkStore = require('cache-chunk-store')
const FSChunkStore = require('fs-chunk-store') // any chunk store will work

const store = new CacheChunkStore(new FSChunkStore(10), {
  // options are passed through to `lru-cache`
  max: 100 // maximum cache size (this is probably the only option you need)
})

store.put(0, new Buffer('abc'), err => {
  if (err) throw err

  store.get(0, (err, data) => {
    if (err) throw err
    console.log(data)

    // this will be super fast because it's cached in memory!
    store.get(0, (err, data) => {
      if (err) throw err
      console.log(data)
    })
  })
})
