High-performance, minimalist web framework for Deno

Fastro is a high-performance, zero-dependency web framework for Deno. It’s built for developers who care about speed, type-safety, and clean code.

• Blazing Fast: Reaches near-native Deno speeds (Benchmarks).
• Zero Dependency Core: Minimalist engine with no external dependencies.
• Zero Friction: Return JSON, strings, or Responses directly.
• Built to Scale: Automatic module loading.
• Rock Solid: 100% core test coverage.

});

app.serve({ port: 8000 });
