Honestly the worst code - but fun as HECK inspired by https://twitter.com/leinweber/status/989267343002951680 it does that but in discord

urgonnaget429d.js

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

let dict = {}

const channels = ["309127154220924929", "441778887064813568", "309894498119319564"] // Place channel IDs in here to monitor - all Dms are monitored by default

client.on('typingStart', (channel, user) => {
    if (user.id != client.user.id) {
        if (channels.indexOf(channel.id) > -1 ) {
            if (dict[channel.id] != true) {
                console.log("[INTERACTION] " + user.tag + " started typing...")
                console.log(" -> GUILD - Start typing... " + channel.name + " (" + user.tag + ")")
                dict[channel.id] = true
                channel.startTyping()
            }
        }
        if (user.dmChannel != undefined) {
            if (dict[user.id] != true) {
                console.log(" -> DM - Sending type indicator to " + user.tag)
                dict[user.dmChannel] = true
                user.dmChannel.startTyping()
            }
        }
    }

})

client.on("typingStop", (channel, user) => {
    if (user.id != client.user.id) {
        if (channels.indexOf(channel.id) > -1 ) {
            console.log("[INTERACTION] " + user.tag + " stopped typing.")
            console.log(" -> GUILD - Stop typing " + channel.name + " (" + user.tag + ")")
            dict[channel.id] = false
            channel.stopTyping()
        }
        if (user.dmChannel != undefined) {
            if (dict[user.dmChannel]) {
                dict[user.dmChannel] = false
                user.dmChannel.stopTyping()
                console.log(" -> DM - Stopping type indicator " + user.tag)
            }
        }
    }
})

client.login("Discord token")
