Pushing a Node App to Heroku

If you're used to pushing Rails apps to Heroku, deploying your first Node app could be a pretty frustrating experience. 

It was for me. 

Here's some tricks to help you deploy:

  • Add Node as an engine dependency in your package.json file:
"engines": {
"node": "4.1.1"
},
  • Delete your node modules and reinstall all your dependencies in your production environment. To do this, run `rm -rf node_modules` and `npm install --production`
  • Double-check everything worked. Run `heroku local web` and visit http://localhost:5000 to see your app as it will appear once deployed.
  • If everything looks good, deploy as usual.
$ git add .
$ git commit -m "Added a Procfile."
$ heroku login
Enter your Heroku credentials.
...
$ heroku create
