# Quarkus Framework Project
## Project Background
###### Pre-Requisite: [Introduction to Play 2.5](/DTWKk_JATk-0rm6ClED08Q), [Introduction to Quarkus](/xSbuep1OR6-NQoIAS_sJoA)

Currently, all Java applications in Ninja Van are built using the [Play 2.5 Framework](https://www.playframework.com/documentation/2.5.x/). However, due to increasing usage of the applications, we need to migrate to another framework that is more scalable and stable.

Specifically for Script Engine, a crucial part of the requirement is polyglot programming (running js on Java). 

Critical endpoint: the endpoint that runs js on Java.
Graal XX, anything to do with the scripts.
