 This codebase was created to demonstrate a fully fledged fullstack application built with **Kotlin + Javalin + Koin + Exposed** including CRUD operations, authentication, routing, pagination, and more.
 
 We've gone to great lengths to adhere to the **Kotlin + Javalin** community styleguides & best practices.
 
 For more information on how to this works with other frontends/backends, head over to the [RealWorld](https://github.com/gothinkster/realworld) repo.

 # How it works
 
 The application was made mainly to demo the functionality of Javalin framework [71](https://github.com/tipsy/javalin/issues/71).
 
 The application was built with:
 
-- [Kotlin](https://github.com/JetBrains/kotlin) as programming language
-- [Javalin](https://github.com/tipsy/javalin) as web framework
-- [Koin](https://github.com/InsertKoinIO/koin) as dependency injection framework
-- [Jackson](https://github.com/FasterXML/jackson-module-kotlin) as data bind serialization/deserialization
-- [Java-jwt](https://github.com/auth0/java-jwt) for JWT spec implementation
-- [HikariCP](https://github.com/brettwooldridge/HikariCP) as datasource to abstract driver implementation
-- [H2](https://github.com/h2database/h2database) as database
-- [Exposed](https://github.com/JetBrains/Exposed) as Sql framework to persistence layer
-- [slugify](https://github.com/slugify/slugify)

 It uses a H2 in memory database (for now), can be changed easily in the `koin.properties` for any other database.
 You'll need to add the correct dependency for the needed `Driver` in `build.gradle`.
