Node.js应用程序适用于工头，但不适用于heroku。 404错误

Question

I'm using Yeoman/bower/grunt to build an angular app. The app runs perfectly on foreman. In my search of similar questions on stack most other people just forgot to create their Procfile or had mistakes in their app.js which ran the app. But I have both of those and I can't figure out what's wrong with them, such that foreman works and not heroku. When I deploy to heroku and open it I get this in the log:

No error (I probably don't fully understand the log), it just kills the app.

My Procfile says: "node app.js"

My app.js file that creates an express server to run the app is:

var express = require('express');

var path = require('path');

var app = express();

app.configure(function(){
  'use strict';
  app.use(express.bodyParser());
  app.use(express.static(path.join(__dirname, 'dist')));
});

var port = process.env.PORT || 5000;

app.listen(port, function() {
    'use strict';
    console.log('server started '+port);
});

Grunt builds the app to my dist folder which I reference above. Any clear mistakes above? When I open the heroku app url, the page states: Cannot GET /

Oh I also have scaled the dynos as some other questions failed to do. And to my knowledge I'm not hardcoding the port.

Answer 1

Figured it out. Always check your .gitignore file! I forgot to remove dist from the file and it hadn't been committed or pushed to heroku.
