- a brand-new Vector implementation
- configurable warnings
- an improved REPL (now JLine 3 based)
Tutorial
In this tutorial we will create a new Play Framework application from scratch and play around with its build.
We will see how to work with config, use compile-time dependency injection, how to dockerize the app, work with json, access the DB, construct the logic so we will have easier time to update Play Framework and so on.
