Lightbend Activator

Finatra v2.x HTTP Server Template Project

Activator will be EOL-ed on May 24, 2017.

We’re making it easier and simpler for developers to get started with Lightbend technologies. This unfortunately means that future releases of Play, Akka and Scala will no longer include Activator support, and Lightbend’s Activator server will be decommissioned by the end of 2017. Instead of supporting Activator to create and set up development projects, we'll be supporting standard Giter8 templates for sbt users and Maven archetypes for Maven users. So going forward,

To create new Lightbend projects

Instead of using the Activator command, make sure you have sbt 0.13.13 (or higher), and use the “sbt new” command, providing the name of the template. For example, “$ sbt new akka/hello-akka.g8”. You can find a list of templates here.

Also, as a convenience, the Lightbend Project Starter allows you to quickly create a variety of example projects that you just unzip and run.

To create new templates

If you want to create new templates, you can now do that in Giter8.

To migrate templates from Activator to Giter8

If you created Activator templates in the past, please consider migrating them to Giter8 with this simple process.

Finatra is a Scala service framework built on top of twitter-sever and Finagle.

This template shows the scaffolding for a simple Http server with a single controller. See the Finatra Http overview for more information and examples.

Full documentation available on the Finatra project site.

Configuring your application

The build.sbt contains the sbt build configuration; you'll want to edit at least the project name and version.

This example by default will run your external service on port :9999 -- you can override this by either changing the code in the ExampleServer class or by passing a different value in the -http.port flag.

Other Examples

More examples are available in the Finatra Examples project on github.
