The Fast, Simple, and Scalable Web Framework for Deno

Fastro is engineered for developers who refuse to compromise. It combines extreme performance with an elegant API, allowing you to build high-throughput microservices and web applications without the friction of traditional frameworks.

Why Fastro?

• Blazing Fast: Optimized to reach near-native Deno speeds. Compare the results.
• Zero Friction: Return JSON, strings, or Responses directly. No boilerplate, just code.
• Ultra Lightweight: Zero external dependencies. Built entirely on Deno standards.
• Built to Scale: Automatic module loading for complex applications.
• AI-Driven Optimization: Since v1, we’ve extensively leveraged AI to fine-tune performance and achieve a rigorous 100% test coverage on our core engine.
• Rock Solid: First-class TypeScript support and production-ready stability.

Quick Start

Create a high-performance server with zero friction:

import Fastro from "https://deno.land/x/fastro/mod.ts";

const app = new Fastro();

app.get("/user/:id", (req, ctx) => {
  return { id: ctx.params.id, status: "active" };
});

app.use((req, ctx, next) => {
  console.log(`${req.method} ${ctx.url.pathname}`);
  return next();
});

await app.serve({ port: 8000 });
