chunk-store-iterator v1.0.3

chunk-store-iterator

Convert an abstract-chunk-store store into an async iterator, or write to using an async iterator.

A majorly simplified version of chunk-store-stream. Dependency free and very fast.

Read/write data from/to a chunk store, with iterators.

Install

npm install chunk-store-iterator

Usage

Create a read iterator

import { chunkStoreRead } from 'chunk-store-iterator'
import FSChunkStore from 'fs-chunk-store' // any chunk store will work
import { Readable } from 'streamx'

const chunkLength = 3
const store = new FSChunkStore(chunkLength)

// ... put some data in the store

const asyncIterator = chunkStoreRead(store, { length: 1200, zeroPadding: true })
const stream = Readable.from(asyncIterator)

stream.pipe(process.stdout)

// or

for await (const chunk of chunkStoreRead(store, { length: 1200 })) {
  console.log(chunk)
}

Write using an iterator

import { chunkStoreWrite } from 'chunk-store-iterator'
import FSChunkStore from 'fs-chunk-store' // any chunk store will work
import fs from 'fs'

const chunkLength = 3
const store = new FSChunkStore(chunkLength)

const stream = fs.createReadStream('file.txt')
await chunkStoreWrite(store, stream)
