Nodejs example

[X7md]

I want nodejs example to how set UnixSocket and pass it to Termux:GUI...

[tareksander]

I tried to document the process in Protocol.md, specifically the "Connection" section. If you want to use Termux:GUI with Node, you should make a library for that, so you don't have to write special code for every project. You should already be familiar with Node and Javascript in general. I found these functions that can help you:
Writing a 32 bit big-endian into a Buffer
Creating a UNIX socket
Calling a program from Node

[X7md]

Still I don't get it, most example I have seen It bind to file path or ip address... I don't know how can I pass socket name 😓

[tareksander]

To use a socket name you should use a "path" that is a null byte ("\0") and then the socket name.

I tried but I got an error with event socket:

https://github.com/X7md/node-termuxGUI/blob/main/index.mjs

now listening

      throw er; // Unhandled 'error' event
      ^

I recommend generating the socket names randomly to avoid collisions. Is this running in the same instance of node as your last test? If yes, you probably didn't close the socket, linux removes abstract sockets automatically when closed.
