Heroku nodejs Procfile never picked up - node.js

Question

It seems that my nodejs application is never deploying on Heroku. While my build successfully completes with the following message:
[154] ./server.ts 2.1 kB {0} [built]
[238] ./src 160 bytes {0} [built]
[244] (webpack)/buildin/module.js 517 bytes {0} [built]
[259] ./dist/server/main.bundle.js 76.1 kB {0} [built]
+ 301 hidden modules
Node server listening on http://localhost:5000
I'm only just seeing Heroku's Blank app:
Other symptoms:
My builds never end:
And no dynos are being instantiated:
This is despite the fact that I'm providing a Procfile, like so:
web: npm start

Note that I need to run a node server since this is an angular universal app and the initial page's contents need to be server-generated.
EDIT: I'm adding my server.ts file (the generated server.js is too long to be reproduced here)
// These are important and needed before anything else
import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import { renderModuleFactory } from '#angular/platform-server';
import { enableProdMode } from '#angular/core';
import * as express from 'express';
import { join } from 'path';
import { readFileSync } from 'fs';
(global as any).XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest;
// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();
// Express server
const app = express();
const PORT = process.env.PORT || 5000;
const DIST_FOLDER = join(process.cwd(), 'dist');
// Our index.html we'll use as our template
const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const {AppServerModuleNgFactory, LAZY_MODULE_MAP} = require('./dist/server/main.bundle');
const {provideModuleMap} = require('#nguniversal/module-map-ngfactory-loader');
app.engine('html', (_, options, callback) => {
renderModuleFactory(AppServerModuleNgFactory, {
// Our index.html
document: template,
url: options.req.url,
// DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
extraProviders: [
provideModuleMap(LAZY_MODULE_MAP)
]
}).then(html => {
callback(null, html);
});
});
app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));
// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
// All regular routes use the Universal engine
app.get('*', (req, res) => {
res.render(join(DIST_FOLDER, 'browser', 'index.html'), {req});
});
// Start up the Node server
app.listen(PORT, () => {
console.log(`Node server listening on http://localhost:${PORT}`);
});
Needless to say, this setup works perfectly on my development machine...
Your help will be highly appreciated. I already spent 2,5 hours on this.

Answer 1

Use process.env.port in server.js to listen
const port = process.env.port || 5000;
app.listen(port);
