I tested locally, the application runs on port 5000 using express

var express = require('express'),
    app = express();

app.use(express.static('www'));

// CORS (Cross-Origin Resource Sharing) headers to support Cross-site HTTP requests
app.all('*', function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
});

// API Routes
// app.get('/blah', routeHandler);

app.set('port', process.env.PORT || 5000);

app.listen(app.get('port'), function () {
    console.log('Express server listening on port ' + app.get('port'));
});

Answer 1

I see several problems here.

1) You need a procfile - https://devcenter.heroku.com/articles/getting-started-with-nodejs#define-a-procfile

2) You do not specify engines in your package. Json

"engines": {
  "node": "0.10.x"
},

https://discussion.heroku.com/t/the-official-node-js-buildpack-is-going-on-a-diet/100

3) node_modules git. npm install ( packages.json)

git. .gitignore. .gitignore:

node_modules

.gitignore .

Git node_modules_

Answer 2

: git add -f package.json .

Answer 3

git init, heroku

heroku git:remote -a yourappname
