Show HN: Are – Rule engine for JavaScript, C#, and Dart with playground
beratarpa Saturday, February 21, 2026I built a rule engine called ARE (Action Rule Event) that follows a simple pipeline: Event → Middleware → Condition Evaluation → Rule Matching → Action Execution.
It's available on npm, NuGet, and pub.dev with the same API design across all three.
I also built a playground where you can experiment with three scenarios (RPG game, smart home, e-commerce) without installing anything. It includes a step-by-step rule debugger, a visual relationship graph, and an animated pipeline diagram.
