scala-getting-started's Introduction

Scala: Getting Started

A barebones Scala app, which can easily be deployed to Heroku.

Deploying to Heroku

Using resources for this example app counts towards your usage. Delete your app and database as soon as you are done experimenting to control costs.

By default, apps use Eco dynos if you are subscribed to Eco. Otherwise, it defaults to Basic dynos. The Eco dynos plan is shared across all Eco dynos in your account and is recommended if you plan on deploying many small apps to Heroku. Learn more about our low-cost plans here.

Eligible students can apply for platform credits through our new Heroku for GitHub Students program.

This application supports the Getting Started with Scala on Heroku article - check it out for instructions on how to deploy this app to Heroku and also run it locally.

Alternatively, you can deploy it using this Heroku Button:

For more information about using Scala on Heroku, see these Dev Center articles:

Can't compile example "Failed to construct terminal; falling back to unsupported"

Basically it doesn't work when I am trying to run sbt. :-(
