Answer 1

I was able to get this to work by adding this into my "package.json" file:

"scripts": {
  "start": "node app",
  "postinstall": "gulp default"
}

The postinstall script is run after the build pack. Check this for more information. The only annoying thing is that all of your dependencies have to live under "dependencies" instead of having separate "devDependencies"

I didn't need to do anything else with buildpacks or configuration. This seems like the simplest way to do it.

Answer 2

There's a specific startup script that Heroku provides;

"scripts": {
  "start": "nodemon app.js",
  "heroku-postbuild": "gulp"
}

note that in your gulpfile.js (gulpfile.babel.js if you es6-ifed your gulp build process), you should have a task name default which will be automatically run after the dependencies are installed via Heroku.
