Run 2 seperate files on startup

My question is I need to run two different files on startup.

"scripts": {
    "start": "node index.js" && "index.html"

^ This is a general idea of what I want to accomplish.

I need to run a file called index.js, and a file called index.html in the same project, at the same time.
I don’t know if it is possible or not.
index.js is a discord bot, and index.html is a website with basic text.

You could add express to your Discord bot. Also, you can’t run .HTML files in the console. You could serve them with express, like previously stated.


I’m quite the noob at this stuff, if you could provide some examples or how you would go about doing it, that would be absolutely perfect!
Thanks again.

// Put Discord Bot code here below the comments.

// Index.html file stuff below(Don't touch unless you read the docs! You could keep the bot from running!)
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.sendFile(__dirname +'/index.html')

app.listen(port, () => {
  console.log(`The app is running at ${port}!`)
