node.js - How does one serve a folder on Heroku? -


just title says, how 1 serve public folder on heroku?

heroku very inflexible, express framework must this, or heroku always spit out errors, code below, how can 1 send "/public" folder? right now, if check source of heroku page, has "index".

const express = require('express'); //for heroku! const socketio = require('socket.io'); const path = require('path'); const victor = require('victor');  const port = process.env.port || 3000; const index = path.join(__dirname + '/public/');  const server = express()   .use((req, res) => res.sendfile(index) )   .listen(port, () => console.log(`listening on ${ port }`));  const io = socketio(server);

with code, heroku sending index.html file within public folder.
