the kLyfft app - event-driven app
A uber-like event-driven application example
|
Note
|
inspired by James Ward’s Koober but much better because Kotlin and Spring Boot used (not Scala 🤮 and Play 🤢) |
|
Warning
|
Flame 🔥 War warning! The demo is written with Groovy (mostly build scripts) and Kotlin. Because why not? 💃 |
