MiXiT website

This project purpose is to power the MiXiT website.

Software design

This project software design goal is to demonstrate what a functional web application developed with Spring Boot 2, Spring WebFlux and Kotlin can look like:

• Reactive and non-blocking
• More functional style and less annotation based than typical Spring applications
• Leverage Kotlin features like Kotlin extensions and reified type parameters for cleaner code
• Simple, fast to start, efficient request processing, low memory consumption
• Constructor based injection
• Immutable Pojos
• Cloud Native

Technologies used

• Language: Kotlin
• Framework: Spring Boot 2.0 with Spring 5 Kotlin support and Spring WebFlux functional
• Engine: Netty used for client and server
• Templates: Mustache (will be migrated later to Kotlin typesafe templates)
• Reactive API: Reactor
• Persistence : Spring Data Reactive MongoDB
• Build: Gradle Script Kotlin
• Testing: Junit 5

TODO

• Use Kotlin Javascript with []dead code elimination](https://kotlinlang.org/docs/reference/javascript-dce.html) tool

Developer guide

Prerequisite

• Install Git
• Fork and clone the project
• Install Java 8
• Install Gulp for development mode
• Depending on your platform, you may have to install libpng (On mac with brew install libpng or on Ubuntu your need to install libpng12 with this package because the default one is too recent)

Run the app in dev mod using command line

• Run ./gradlew bootRun in another terminal
• Run gulp watch in another terminal
• Open http://localhost:8080/ in your browser
• If you want to debug the app, add --debug-jvm parameter to Gradle command line

Sass, TypeScript, messages*.properties and templates should be live reloaded.

Import and run the project in IDEA

• Make sure you have at least IntelliJ IDEA 2017.2.x and IDEA Kotlin plugin 1.1.4+ (menu Tools -> Kotlin -> configure Kotlin Plugin Updates -> make sure "Stable" channel is selected -> check for updates now -> restart IDE after the update)
• Import it in IDEA as a Gradle project
• In IntelliJ IDEA, right click on Application.kt then Run ... or Debug ...
• Run gulp watch in another terminal
• Open http://localhost:8080/ in your browser

Sass, TypeScript, messages*.properties and templates should be live reloaded.

Package and run the application from the executable JAR:

./gradlew clean build
java -jar build/libs/mixit-1.0.0-SNAPSHOT.jar

Deploy the app on Cloud Foundry

./gradlew clean build
cf push
