Write ArrayBuffer on WS message

[matiaslopezd]

Hi! Does anyone know how to write a chunk of file with createWriteStream on the message event?

I tried:

message(ws, message, isBinary) {
const writeStream = fs.createWriteStream(path, { encoding: 'binary' });
writeStream.write(Buffer.from(message));
}

The output file is empty 🤔 @uNetworkingAB

I guess you need to (deep) copy the arrayBuffer before passing it to write

Thanks @uNetworkingAB !!

const bufferCopy = message.slice(0);
writeStream.write(Buffer.from(bufferCopy));
