How to generate image from stream of raw input?

I am trying to create an image (ideally to be output as a png) from raw pixel data, but I’m struggling to understand the desired format

const rs = Readable();
  const transformer = sharp({
    raw: {
      width,
      height,
      channels: 3,
    },
  });
  rs.pipe(transformer).pipe(createWriteStream(outputPath));

I have tried setting _read on rs to push Uint8Arrays, Buffers, and other types representing RGB data, but I inevitably get the Error: Unexpected data on Writable Stream error

I’m stumped, any help would be greatly appreciated
