Bun provides several convenience functions for reading the contents of a ReadableStream into different formats. This snippet reads the contents of a ReadableStream to an ArrayBuffer, then creates a Buffer that points to it.

const stream = new ReadableStream();
const arrBuf = await Bun.readableStreamToArrayBuffer(stream);
const nodeBuf = Buffer.from(arrBuf);

See Docs > API > Utils for documentation on Bun’s other ReadableStream conversion functions.
