Welcome to Bklar 🐰

Bklar (pronounced buh-klar) is a modern web framework built specifically for Bun.

It is designed to be incredibly fast by leveraging native Bun APIs, while offering a Developer Experience (DX) comparable to sophisticated frameworks like NestJS or Hono, but with a much simpler surface area.

Why Bklar?

🚀 Native Speed

Built directly on Bun.serve and Bun.file. No Node.js compatibility layers slowing you down.

🛡️ Type Safe

First-class Zod integration. Input validation and type inference work out of the box.

🔌 Battery Included

Everything you need (Logger, CORS, JWT, Rate Limit, Swagger) is available as an official, optimized package.

⚡ Realtime

Native WebSocket support integrated directly into the router. No complex setup required.

Quick Look

Here is a complete API with validation and Swagger documentation in just a few lines:

import { Bklar } from "bklar";
import { z } from "zod";

const app = Bklar();

app.get(
  "/users/:id",
  (ctx) => {
    // ctx.params.id is strictly typed!
    return ctx.json({ id: ctx.params.id, name: "Bun User" });
  },
  {
    schemas: {
      params: z.object({ id: z.coerce.number() }),
    },
    doc: {
      summary: "Get User",
      tags: ["Users"],
    },
  }
);

app.listen(3000);
