it-flat-batch

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

About

The final batch may be smaller than requested batch size.

Example

import batch from 'it-flat-batch'
import all from 'it-all'

// This can also be an iterator, async iterator, generator, etc
const values = [[0, 1, 2], [3], [4]]
const batchSize = 2

const result = all(batch(values, batchSize))

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

Async sources must be awaited:

import batch from 'it-flat-batch'
import all from 'it-all'

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

const result = await all(batch(values(), batchSize))

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