Heroku allways starting "npm" start even with Procfile and specific web process

Question

I am getting heroku starting "npm start" on web process no matter I include Procfile or not. I am building a simple page with React/Redux and using webpack to bundle.

Actually my project structure is:

/projectName
 /public -->folder create during bundling with bundle.js and new html file 
 /src --> contains React and Redux components 
 .babelrc
 .gitignore
 index.html -->original html
 index.js --> express server (nothing special, just serving public/index.html on the root ("./) request)
 package.json
 Procfile (no extension, uppercase P in the name so no error there)
 webpack.config.js

All is working in local.

the Package.json file :

/ {
    "name": "redux-heroku",
    "version": "1.0.0",
    "description": "",
    "engines": {
       "node":"6.10.1"
    },

   "scripts": {
        "prod": "webpack -p",
        "start":"node index.js",
        "start:web": "webpack-dev-server"
   },

  "author": "",
  "license": "ISC",
  "dependencies": {
     "babel-core": "^6.25.0",
     "express": "^4.15.3",
     "react": "^15.6.1",
     "react-dom": "^15.6.1",
     "react-redux": "^5.0.5",
     "react-router": "^4.1.1",
     "react-router-redux": "^4.0.8",
     "redux": "^3.6.0",
      "redux-thunk": "^2.2.0"
   },
  "devDependencies": {
      "babel": "^6.23.0",
      "babel-loader": "^7.1.1",
      "babel-preset-es2015": "^6.24.1",
      "babel-preset-react": "^6.24.1",
      "css-loader": "^0.28.4",
      "html-webpack-plugin": "^2.29.0",
      "webpack": "^3.2.0",
      "webpack-dev-server": "^2.5.1"
   }
 }

The index.js express file :

var express = require('express');
var app = express(); 
var port = process.env.port || 3000; 

app.use(express.static(__dirname +'/public')); 

app.get('/', function(req, res){
    res.render('index');
})

app.listen(port);

The Procfile: web: node index.js

So I delete the Procile et push all on heroku, getting the same thing, anyway I was expecting that according to this Stopping Heroku from running npm start + what to run instead?

I am a bit lost, thank you for you insight!!

do you want to know when to use procfile or just npm scripts?

Procfiles can contain additional process types. For example, you might declare one for a background worker process that processes items off of a queue.

Package.json scripts are executed when procfile is not found and only limited scrips are available

If you have custom scrips you use procfile
