Create chunked iterator from Uint8Array iterables

import { createReadStream } from 'node:fs';
import chunked from '@intrnl/chunked-uint8-iterator';

let stream = createReadStream('./archive.zip');

for (let values of chunked(stream)) {
  // ...
}

This will default to yielding 512 bytes of chunks at a time, you can configure this by passing a number as the second argument.

for (let values of chunked(stream, 1024)) {
  // ...
}

If the iterable ends with less than the given chunk size, it will yield the remaining bytes as is without padding.

Using web streams

Your web browser might not support using ReadableStream directly as an async iterable, if that's the case, this library provides createStreamIterator which you can pass directly into chunked.

import chunked, { createStreamIterator } from '@intrnl/chunked-uint8-iterator';

let stream = file.stream();

for (let chunks of chunked(createStreamIterator(stream))) {
  // ...
}
