Does not send messages from host to browser equal or to 65536 length.

In Node.js this code https://github.com/simov/native-messaging/blob/master/protocol.js does this

Yes. You can utilize Native Messaging. See https://github.com/simov/native-messaging.

I've only dabbled with the shared libraries once, with the help of the owner of the lnked repository. I wound up solving the issue adjusting the code I was working on https://github.com/saghul/txiki.js/issues/294.

I have written the same code in C++ https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.cpp, Python https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.py, and QuickJS (C source code) https://github.com/saghul/txiki.js/issues/294. QuickJS is the only implementation that winds up clipping the end of real-time audio capture.

QuickJS is awesome, simple to use and very easy to integrate.

Over the past few years I slowly built a small JS runtime using QuickJS as the engine and libuv as the platform layer, amongst other things, in case anyone wants to take a look: https://github.com/saghul/txiki.js
