JarCastingimmediate-chunk-store 
Immediate put/get for abstract-chunk-store compliant stores
Makes store.put() chunks immediately available for store.get(), even before the store.put() callback is called. Data is stored in memory until the store.put() is complete.
Install
npm install immediate-chunk-store
Usage
var ImmediateChunkStore = require('immediate-chunk-store')
var FSChunkStore = require('fs-chunk-store') // any chunk store will work
var store = new ImmediateChunkStore(new FSChunkStore(10))
store.put(0, Buffer.from('abc'), function () { /* yolo */ })
// And now, get the same chunk out BEFORE the put is complete
store.get(0, function (err, data) {
if (err) throw err
console.log(data.toString()) // 'abc'
})
