counter

Counter Example

A minimal in-memory counter API built with the Vania framework. No database — just a shared Counter object behind four routes.

Endpoints

Method	Path	Description
GET	/api/counter	Current value
POST	/api/counter/increment	Add one, return value
POST	/api/counter/decrement	Subtract one, return value
POST	/api/counter/reset	Reset to zero

Layout

lib/
  app/counter.dart                          # the counter logic (no HTTP)
  app/http/controllers/counter_controller.dart
  route/api_route.dart
  app/providers/route_service_provider.dart
  config/app.dart
bin/server.dart
test/counter_test.dart                       # unit tests for the counter

Running

dart pub get
dart run bin/server.dart

Tests

The counter logic lives in a plain Counter class, so it is tested directly without a server:
