I don't know how node is processing the stream and buffering or not buffering. I just invested the past few hours into researching Node.js buffering and not buffering read(). There are more than one issue regarding the subject-matter, e.g., https://github.com/nodejs/node/issues/2972, https://github.com/nodejs/node-v0.x-archive/issues/4000, https://github.com/nodejs/node/issues/6379. From what I gather Node.js blames the process itself. However, I run the same algorithm using Python, C++, C, QuickJS JavaScript engine where the RSS does not exponentially increase during usage.
The Node.js Native Messaging host creates a child process and streams captured system audio to the browser https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio_node.js.
// Node.js Native Messaging host // https://github.com/simov/native-messaging/blob/master/protocol.js // https://github.com/simov/native-messaging/blob/master/nodejs/example.js // Might be good to use an explicit path to node on the shebang line // in case it isn't in PATH when launched by Chrome process.stdin.on('readable', () => { let input = []; let chunk; while ((chunk = process.stdin.read())) { input.push(chunk); } input = Buffer.concat(input); const msgLen = input.readUInt32LE(0); const dataLen = msgLen + 4; if (input.length >= dataLen) { const content = input.slice(4, dataLen); const json = JSON.parse(content.toString()); handleMessage(json); } });
