Can xterm be used to connect devices via tcp instead of WebSocket?

hi,I'm investigating a device log display scenario that involves scrolling through the interface to view logs, download log files, enter commands, and so on. But this is an IoT device, and it is connected to the outside via TCP. Our client is based on Electron, and I want to use xterm to display log messages sent by the device. But I see that xterm usually uses WebSocket, so I'm not sure if that's possible

It depends on how you set up your electron client:

JS in a browser context normally has no access to raw TCP sockets, it needs some sort of HTTP wrapping (either by Ajax/long polling or via websockets). Thats the reason why its often done with websockets.

But with electron the situation changes - you can either use the electron client process as proxy to translate between TCP and the browser context (again forward data with websockets or with IPC), or allow the browser context to load nodejs modules and hook TCP handling in there directly (via the net module).

In the end this is more an electron question than xterm.js related. To get data into xterm.js you only have to feed it to term.write - how you get the data to that point, is up to you.

Yes, I found this point too, thank you very much! 😊 I'm going to write a net module-based plugin using the xterm-addon-attach plugin
