🌟 Superpowers

• 🌐 Multi-runtime support - Bun (default), Deno, Node.js, Vercel, Cloudflare Workers, Fastly Compute, Lambda, etc.
• 🔒 End-to-end type safety - From params to response, full TypeScript integration
• ⚡ Bun-native performance - Built for Bun runtime with native validation
• 🧩 Client integration - Auto-generated type-safe HTTP client
• 🛡️ Validation built-in - Zod integration for runtime safety
• 🔌 Extensible architecture - Middleware, hooks and macros system
• 📝 Standard Schema - Compatibility with the standard schema so you can use it with Zod, Arktype, etc.

🚀 Launch in 30 Seconds

1. Install with Bun:

bun add hedystia

2. Create your first API:

import { Hedystia, h } from "hedystia";

const app = new Hedystia()
  .get("/hello/:name", (ctx) => `Hello ${ctx.params.name}!`, {
    params: h.object({ name: h.string() }),
    response: h.string()
  })
  .listen(3000);

3. Generate client and consume API:

import { createClient } from "@hedystia/client";

const client = createClient<typeof app>("http://localhost:3000");

// Fully typed request!
const { data } = await client.hello.name("World").get();
console.log(data); // "Hello World!"

💡 Why Developers Love Hedystia

🔄 Full-stack Type Safety

// Server-side validation
.post("/users", (ctx) => {...}, {
  body: h.object({
    email: h.email(),
    age: h.number()
  })
})

// Client-side types
await client.users.post({
  body: {
      email: "[email protected]", // Autocompletes!
      age: 25 // Type-checked
  }
});

📖 Swagger Integration

import { swagger } from "@hedystia/swagger";

const swaggerPlugin = swagger({
  title: "My API",
  description: "An example API with Swagger",
  version: "1.0.0",
  tags: [
    { name: "users", description: "User operations" },
  ],
});

app.use("/swagger", swaggerPlugin.plugin(app));

app.listen(3000);

⚡ Performance First

• Bun runtime optimized
• Faster by default
• Own type validation system
• Faster than Express
• Built-in response compression

🧩 Modern Feature Set

// File uploads
.post("/upload", async (ctx) => {
  const formData = await ctx.body; // FormData type
})

// Binary responses
.get("/pdf", () => new Blob([...]), {
  response: h.instanceof(Blob)
})

// Nested routing
.group("/api/v1", (v1) => v1
  .group("/users", (users) => users
    .get("/:id", ...)
  )
)

.macro({
  rateLimit: () => ({
    resolve: async (ctx) => {
      // Implement your logic
    }
  })
})
