This was a take-home coding exercise for an interview where the task was to build a REST API with CRUD operations that writes data to an in-memory database, using all the technologies listed below:

Kotlin, Spring Boot, Spring Web, JPA, H2 (in-memory db), JUnit 5, Mockito, and Gradle.

If this was destined to be a production app, next steps would include:

• more features
• lots more tests. Unit, functional, end-to-end
• input validation
• ktlint
• change from in-memory to persisted db
• specify dependency versions in build.gradle
• enable spring boot monitoring

and might include:

• document the API (e.g., Swagger)
• change server
• create a UI and/or a reference client

To build image and run with docker, use ./gradlew clean jibDockerBuild && docker-compose up --build --remove-orphans Google's jib plugin pushes the image it builds to docker registry (run docker images to see a list) Container entrypoint set to [java, -cp, /app/resources:/app/classes:/app/libs/*, timrapp.springbootjpah2.vlorp.VlorpApplicationKt]

Docker starts a Redis container, but it's not used by the app. Yet.

Using Ktlint 0.36 and org.jlleitschuh.gradle.ktlint gradle plugin.
