PS C:\Users\USER\Documents\aaa-PROJECTS\Main-accounting-app>

here is my procfile

web: node app.js

here is my appjs

var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
const mongoose = require('mongoose');
const cors = require('cors');
const bodyParser = require('body-parser');


var indexRouter = require('./api/routes/index');
var usersRouter = require('./api/routes/users');

mongoose.connect('mongodb://xxx:xxx.mlab.com:39921/demobusinesshub',{
    // mongodb://localhost:27017/testbusinesshub
    // mongodb://xxx:xxx.mlab.com:39921/demobusinesshub
}).then(c => console.log('connected to db'))
.catch(c => console.log('connection to db error'))

var app = express();
app.use(cors());

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));

app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

// bodyparser

app.use(bodyParser.json());

app.use('/', indexRouter);
app.use('/users', usersRouter);

const port = process.env.PORT || 3000;
const host = '0.0.0.0';

app.listen(port, host, ()=>{
    console.log('Server started on port '+ port);
});
module.exports = app;

here is my package json

{
  "name": "main-accounting-app",
  "version": "1.0.0",
  "description": "",

  "scripts": {
    "start": "node app"

    "jsonwebtoken": "^8.3.0",
    "mongoose": "^5.1.6",
    "morgan": "~1.9.0"
  }
}

and in my auth file in my angular service

return this.http.post('' + this.domain + 'users/register', newUser, {headers: headers}).pipe(map(res => res.json()));

where in production this.domain = '' //(an empty string)

so i dont get what is wrong, i have literially searched the web and i'm being told to check port etc and i've done all that. at this stage i am really confused and i dont know what to do . also i've ran ng build in my angular terminal and its being bunduled to the public folder of my express application. runing this with heroku local works and gives no errors. also running this with my normal local server works too

Based on 'bcrypt_lib.node: invalid ELF header' it looks like something is wrong with the bcrypt module, I would look more at that than I would look at ports. — Adam H, Jul 19 '18 at 18:20
I don't have a .gitignore file. I already used the command git add . — ayotycoon, Jul 19 '18 at 18:22
just checked and no i am not modified: angular-src (modified content, untracked content) modified: app.js modified: package.json modified: public/3rdpartylicenses.txt modified: public/main.js modified: public/main.js.map modified: public/vendor.js modified: public/vendor.js.map — ayotycoon, Jul 19 '18 at 18:28
or maybe i was , i ran git rm -r --cached . and i got bunch of stuff with syntaxs like this . rm 'node_modules/qs/test/utils.js' — ayotycoon, Jul 19 '18 at 18:30

from this question: question on stackoverflow the problem is that you installed the module bcrypt on windows machine and the heroku machine is linux and you pushed the module to the heroku machine, so the bcrypt dependency will not work.

so to fix it delete the node_modules folder on the heroku machine and add .gitignore file to your project and in the file add this line:

node_modules

and than run: git add . and push to heroku master. so the heroku machine will automatic install your dependencies including bcrypt for linux.
