Kotlin Functional Quiz

This repository contains an exploratory project that I've written using Http4k, Arrow and Exposed. The project is intended to be written in a functional style.

Running the project

The easiest way to run the project is to clone the repository and then import the project into Intellij IDEA and run the main() function in Application.kt.

You can also build the jar using .gradlew jar and then run the jar with java.

Functionality

Http4k Contract routes with Open API v3

The project utilises Http4k's contract routes functionality to provide type-safe routes with automatically generated Open API v3 documentation.

When running the project locally, the documentation can be found at http://127.0.0.1:8080/#/

Validation and error handling with Arrow

The project utilises Arrow 2.0's Either class to achieve validation and error handling.

Database persistence with Exposed

The project uses Jetbrains Exposed framework to work with persistence. This project uses an H2 database file.
