it-split

Splits Uint8Arrays emitted by an (async) iterable by a delimiter

About

Searches Uint8Arrays emitted by an (async)iterable for a delimiter and yields chunks split by that delimiter.

Example

import split from 'it-split'

const encoder = new TextEncoder()

// This can also be an iterator, generator, etc
const values = [
  encoder.encode('hello\nwor'),
  encoder.encode('ld')
]

const arr = all(split(values))

console.info(arr) // [encoder.encode('hello'), encoder.encode('world')]
Copy

You can also split by arbitrary delimiters:

const values = [
  Uint8Array.from([0, 1, 2, 3]),
  Uint8Array.from([0, 1, 2, 3]),
  Uint8Array.from([1, 1, 2])
]
const delimiter = Uint8Array.from([1, 2])

const arr = all(split(values, {
  delimiter
}))

console.info(arr) // [ Buffer.from([0]), Buffer.from([3, 0]), Buffer.from([3, 1]) ]
Copy

Async sources must be awaited:

import split from 'it-split'

const encoder = new TextEncoder()

const values = async function * () {
  yield * [
    encoder.encode('hello\nwor'),
    encoder.encode('ld')
  ]
}

const arr = await all(split(values()))

console.info(arr) // [encoder.encode('hello'), encoder.encode('world')]
Copy
