where and how to deploy my nodejs whatsapp-web-js app

Question

I am working on a project which basically is a whatsapp-bot which is working fine as expected but the problem im going through is that.. The bot only work when the terminal is working and obviously I can't run my PC 24x7 . I need to make terminal run into the cloud .

Here is my index.js file :-

const axios = require('axios')

const { Client, LocalAuth, MessageMedia } = require('whatsapp-web.js');
const client = new Client({
    authStrategy : new LocalAuth()
});

client.on('qr', qr => {
    qrcode.generate(qr, {small: true});
});

client.on('ready', () => {
    console.log('Client is ready!');
});

client.on('message',async message => {
    const content = message.body
    if(content === 'meme plz') {
        const meme = await axios('https://meme-api.herokuapp.com/gimme')
        .then(res => res.data.url)
        client.sendMessage(message.from, await MessageMedia.fromUrl(meme))
    }
    else if(content === 'joke plz') {
        const joke = await axios('https://v2.jokeapi.dev/joke/Any?safe-mode')
        .then(res => res.data)

        const jokemsg = await client.sendMessage(message.from,joke.setup || joke.joke)
        if(joke.delivery) setTimeout(function(){jokemsg.reply(joke.delivery)},5000)
    }
    
});
client.on('message', message => {
    if(message.body === 'hi') {
        message.reply('hlo');
    }
});


client.initialize();
