Deploy your Rails API onto Heroku
Go to your Heroku Dashboard. Click “new”-> “create new app”
Give your app a name and click “Create app”
There are several ways to deploy
- Heroku CLI – push your project up to Heroku from your command line
- Github – Heroku is connected to github, so everytime github is updated your app is
- Dropbox connected
- Container Registry
We will be using Heroku CLI. If you need to install use these instructions
By default Heroku ONLY supports the master branch. If you want to push up a branch other than master follow these instructions.
Add Heroku as a remote to your project
heroku git:remote -a name-of-your-heroku-app
Push your project to Heroku
git push heroku master
Did you just get an error? Did you use sqlite3 for your project?
remote: An error occurred while installing sqlite3 (1.3.13), and Bundler cannot
remote: Make sure that `gem install sqlite3 -v ‘1.3.13’` succeeds before bundling
remote: In Gemfile:
remote: ! Failed to install gems via Bundler.
Migrate and seed your database
In your command line run the following commands.
heroku run rake db:migrate
heroku run rake db:seed
Test your API using Postman
To get the address, just go back to the Heroku dashboard and click on “Open app” to get the link to your online api
If you made it this far, your API should be deployed and now test it as you did locally (you did test locally didn’t you???).
The reason you need postman is if you setup your Rails API correctly when you query your site via browser you should get an error
This appname-api.herokuapp.com page can’t be found
but if you connect to it via postman you should get back the appropriate response
