/////////////////////////////////////////////////////////////////////////////////////////////////////////////
These instructions are based of the tutorial here:
  https://medium.com/@ryanchenkie_40935/angular-cli-deployment-host-your-angular-2-app-on-heroku-3f266f13f352 
They solve the aot issue that I encountered when following that tutorial.
/////////////////////////////////////////////////////////////////////////////////////////////////////////////

Create a new Angular 2 project using the cli.

Add the following lines to package.json under the scripts section. 
  "postinstall": "ng build --env=prod",
  "start": "node server.js"
  
In the package.json move the following items from devDependancies to dependancies.
  "@angular/cli"
  "@angular/compiler-cli" 

Add an engines section to the package.json. It should look similar to the following.
  "engines": {
    "node": "6.11.1",
    "npm": "3.10.9"
  }

Run the following command from the project root.
  npm install --save express

Create a new file called server.js in the project root that contains the following text.
  // server.js
  const express = require('express');
  const path = require('path');
  const app = express();
  // If an incoming request uses
  // a protocol other than HTTPS,
  // redirect that request to the
  // same url but with HTTPS
  const forceSSL = function() {
    return function (req, res, next) {
      if (req.headers['x-forwarded-proto'] !== 'https') {
        return res.redirect(
         ['https://', req.get('Host'), req.url].join('')
        );
      }
      next();
    }
  }
  // Instruct the app
  // to use the forceSSL
  // middleware
  app.use(forceSSL());

  // Run the app by serving the static files
  // in the dist directory
  app.use(express.static(__dirname + '/dist'));
  // Start the app by listening on the default
  // Heroku port
  app.listen(process.env.PORT || 8080);

  // For all GET requests, send back index.html
  // so that PathLocationStrategy can be used
  app.get('/*', function(req, res) {
      res.sendFile(path.join(__dirname + '/dist/index.html'));
  });
