it-batch

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

About

The final batch may be smaller than the max.

Example

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

// This can also be an 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]
Copy

Async sources must be awaited:

import batch from 'it-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]
Copy
