Modules

Backend

Full stack Scala application with a Scalajs frontend. Depends on Frontend. This application is built on on top of Smithy4s and is deployed as a Docker container on fly.io.

Live at: https://morning-bird-7081.fly.dev/

Deployed on a very small 2vcpu and 512mb vm.

Configuration

The backend can be configured.

1. SMITHY_CLASSPATH_CONFIG: location of a json file used to load dependencies to include during code gen. The file content looks like this:

{
  "entries": {
    "com.disneystreaming.alloy:alloy-core:0.2.8": "/opt/docker/smithy-classpath/alloy-core-0.2.8.jar"
  }
}

Frontend

ScalaJS application shipped in Backend.

Developement

It is recomended that you have 3 long running proccesses to develop this application:

1. backend: sbt ~backend/reStart
2. cd into modules/frontend and run npm i && npm run dev
3. frontend scalajs: sbt "~frontend/fastLinkJS"

Dockerhub

The images are pushed to the docker hub so you can deploy them on your own infrastructure.

• latest: daddykotex/smithy4s-code-generation:latest
• latest: daddykotex/smithy4s-code-generation:with-dependencies
• daddykotex/smithy4s-code-generation:$SHA
• daddykotex/smithy4s-code-generation:with-dependencies-$SHA

Fly.io

The images are pushed to the fly.io registry so that it can be deployed quickly from there.
