readableStreamToArrayBuffer

stream: ReadableStream<ArrayBufferLike | ArrayBufferView<ArrayBufferLike>>
): ArrayBuffer | Promise<ArrayBuffer>;

Consume all data from a ReadableStream until it closes or errors.

Concatenate the chunks into a single ArrayBuffer.

Each chunk must be a TypedArray or an ArrayBuffer. If you need to support chunks of different types, consider readableStreamToBlob

@param stream

The stream to consume.

@returns

A promise that resolves with the concatenated chunks or the concatenated chunks as an ArrayBuffer.

class ReadableStream<R = any>

This Streams API interface represents a readable stream of byte data. The Fetch API offers a concrete instance of a ReadableStream through the body property of a Response object.

MDN Reference

type ArrayBufferView<TArrayBuffer extends ArrayBufferLike = ArrayBufferLike> = NodeJS.TypedArray<TArrayBuffer> | DataView<TArrayBuffer>

class ArrayBuffer

Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

  • readonly [Symbol.toStringTag]: string
  • readonly byteLength: number

    Read-only. The length of the ArrayBuffer (in bytes).

  • newByteLength?: number
    ): void;

    Resizes the ArrayBuffer to the specified size (in bytes).

    byteLength: number

    Resize an ArrayBuffer in-place.

  • begin: number,
    end?: number

    Returns a section of an ArrayBuffer.

  • newByteLength?: number

    Creates a new ArrayBuffer with the same byte content as this buffer, then detaches this buffer.

    MDN

  • newByteLength?: number

    Creates a new non-resizable ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
