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.
