awful horrible hacky piece of shit node.js script for sending out discord messages (user and message content) into a locally hosted REST api

msg.js

const { json } = require("body-parser");
const Eris = require("eris");
var express = require('express');
var app = express();
var fs = require("fs");


var usr  
var cont

var msgRest;


const bot = new Eris("Bot YOUR_TOKEN_HERE");
bot.on("ready", () => {
    console.log("Bot started...");
});
bot.on("messageCreate", (msg) => {
    usr = msg.author.username
    message = msg.content
    msgRest = `{"user":"${usr}", "content":"${message}"}`;
    console.log(`<${usr}>: ${cont}`);
    
});
bot.connect();

app.get('/currentMessage', function (req, res) {
    console.log(msgRest)
    //console.log( data );
    //parsed = JSON.parse(msgRest)
    res.end( msgRest );
});

var server = app.listen(5000, function () {
    var host = server.address().address
    var port = server.address().port
    console.log("Channel scanner listening at http://%s:%s", host, port)
})
