it-length-prefixed-stream

Read and write length-prefixed byte arrays over a duplex stream

About

This module makes it easy to send and receive length-prefixed byte arrays over streams.

Example

import { lpStream } from 'it-length-prefixed-stream'

const stream = lpStream(duplex)

// read the next length-prefixed chunk
const bytes = await stream.read()

// write a length-prefixed chunk
await stream.write(Uint8Array.from([0, 1, 2, 3, 4]))

// write several chunks, all individually length-prefixed
await stream.writeV([
  Uint8Array.from([0, 1, 2, 3, 4]),
  Uint8Array.from([5, 6, 7, 8, 9])
])
