what do people make with this?

VIBE 1

Wire controllers, routing, and services explicitly in a MyComponents class instead of using runtime dependency injection.

VIBE 2

Catch dependency wiring mistakes at compile time before the app even runs.

VIBE 3

Spin up a fresh app instance per test suite using custom ScalaTest helpers.

VIBE 4

Migrate an existing Play app away from convention-based automatic dependency injection.

how do i run it?

Difficulty · moderate time til it works · 1h+

Requires understanding manual dependency wiring instead of Play's default runtime DI, which has a learning curve.
