Template for deployment

With this template, you are ste to deploy your application to Heroku. I´m using a Spring backend, React JS Frontend with MongoDB database.

Try it out

• Standard react starting-page: https://kevinowens.herokuapp.com/
• Simple DB- request to save new Document and show all Documents: https://kevinowens.herokuapp.com/api (if you count the items, you know how many people visited the site :D)

- What you need:

• Heroku account
• MongoDB Atlas

- What to do:

• Clone this Repo and connect it with a new Repo of yours(you can delete the .git Folder and make a new git init).

• Install or sign up to Heroku and MongoDB using the Links above.

• MongoDB Atlas:

  • create a Cluster for your App (check the pricing, there is a free tier)
  • After you created it, use the connect button => connect your application => java/current version => copy the connection string

• Let´s head to Heroku:

  • Create an App for your application
  • Head to settings and reveal Config Vars
  • Add the Key URI and as Value paste in your connetion string (replace user and password with your values)
  • Since we are already on Heroku, we need some kind of authentication for GitHub, in this case an API-Key. We can generate our API-Key in Heroku by clicking the User-icon (top-right) => Account settings => scroll down untill you see API-Key
  • Either generate or copy your API-Key.

• Github:

  • We have save this API-Key in our Repo, to Login to Heroku.
  • Go to your Repo => Settings => Secrets => New Repository Secret
  • Save your API-Key as HEROKU_API_KEY, save, and now GitHub and Heroku can communicate.

- What to change:

• pom.xml:

  • change the finalName to your Appname.
  • You can change the groupId if you like.

• Github Action:

  • All points of change are marked inside th action.

• Dockerfile:

  • Please change the Maintainer :D
  • The .jar name should be changed to the same name, as in the pom.xml under 'finalName' (at three places, you´ll manage to do it!)

• You can remove all Packages in the backend, they are just an example for the DB connection.

- Problems

• If you encounter any problems using this template, please let me know by stating an issue on GitHub.
