This is a small application acting as an illustration to a blog post. It uses:

• Kotlin as the language
• Ktor to serve HTTP requests
• JUnit 5 for testing

You can read more about the reasoning and setup here: https://medium.com/porterbuddy/rolling-your-own-dependency-injection-7045f8b64403

This repo has also been extended to encompass some other examples of code. To see all our blogposts go to https://medium.com/porterbuddy

Building and running

To build a ShadowJAR as a single binary distributable do:

./gradlew build shadowJar

Then to run the application:

java -jar ./build/libs/di-app.jar

Caveats

• The KTor setup with tests does not support parallel running. You might want to look into JUnits extensions and extensioncontext to handle that.
• We normally integrate Liquibase verification into the startup code of our app. Just do that as you wire the DI context together.
