it-batched-bytes

Takes an async iterator that emits byte arrays and emits them as fixed size batches

About

The final batch may be smaller than the max.

Example

import batch from 'it-batched-bytes'
import all from 'it-all'

// This can also be an iterator, generator, etc
const values = [
  Uint8Array.from([0]),
  Uint8Array.from([1]),
  Uint8Array.from([2]),
  Uint8Array.from([3]),
  Uint8Array.from([4])
]
const batchSize = 2

const result = all(batch(values, { size: batchSize }))

console.info(result) // [0, 1], [2, 3], [4]

Async sources must be awaited:

import batch from 'it-batched-bytes'
import all from 'it-all'

const values = async function * () {
  yield Uint8Array.from([0])
  yield Uint8Array.from([1])
  yield Uint8Array.from([2])
  yield Uint8Array.from([3])
  yield Uint8Array.from([4])
}
const batchSize = 2

const result = await all(batch(values, { size: batchSize }))

console.info(result) // [0, 1], [2, 3], [4]
