Mastering Heroku App Deployments with Node.js

Learn about the benefits and drawbacks of microservices with best practices for your own architecture, brought to you in partnership with Iron.io.

After some months developing with node.js, now is the time to deploy these apps and see which problems appear.

For the first two apps I decided to go with Heroku (although in a previous posts I commented that maybe Amazon was a better option). and here I’m showing you some of the commands I’ve been using on the deployment to make it easier for you:

Of course, you must install heroku toolbelt.

The first commands you must use are:

heroku login
heroku create

With these two commands, you will log in heroku and create the app.

After this, you can upload your apps to heroku automatically with git (so first, install git!):

git push heroku master

The reason I’m writing this article is mostly because I had a problem, and heroku origin got wrong. After that, I couldn’t upload heroku apps. I could create another app, and point my domain to the new app… but that’s starting all over again, and having an empty database.

So, what could you do to solve it? First of all, you have to list all your heroku apps to select the one you want to point to:

heroku list

If you cannot retrieve this info from the command line tools, you can access heroku web and log in to watch this information.

Once you know your app name you can configure git to access your heroku app. First remove you last heroku remote origin, and then add the new one:

git remote rm heroku
git remote add heroku git@heroku.com:.git

Now that you’ve configured your heroku app, you can show your heroku app info:

heroku info
