How to make a website with a live nodejs console output

As the title already says I want to make a Nodejs script which starts a website with the live console output of a subprocess.

This is my subprocess:

const { spawn } = require('child_process');

const subprocess = spawn(process.argv[0], ['bot_index.js'], {
        detached: false,
        stdio: ['ignore', process.stdout, process.stderror]
    });

To make it more clearly: I want to create a webpage (with express perhaps?) which then provides the live console output of this subprocess (process.stdout)

I would be very happy if someone could help me.

Thanks in advance!
