Hono: The Ultra-Fast Web Framework for Edge, Bun, Deno, and Node

Hono's RegExpRouter allocates zero objects per request and runs identically on Cloudflare Workers, Bun, Deno, and Node - here is why teams are choosing it over Express.

Hono: The Ultra-Fast Web Framework for Edge, Bun, Deno, and Node

What Is Hono?

One AI engineering post, weekly

LLM benchmarks, prompt techniques, and token-cost breakdowns — not another AI news roundup.

Hono (Japanese for "flame") is a web framework that runs on any JavaScript runtime. It was built from the ground up for the Edge, which means it has zero Node.js dependencies, a 14KB bundle size, and a router that makes zero allocations per request.

The Router

Hono's RegExpRouter compiles all routes into a single regular expression at startup. At request time, one regex match finds the handler with zero object allocations:

typescript
import { Hono } from "hono";

const app = new Hono();

app.get("/users/:id", (c) => {
  const id = c.req.param("id");
  return c.json({ id });
});

app.post("/users", async (c) => {
  const body = await c.req.json();
  return c.json({ created: body }, 201);
});

export default app;

Benchmark against Express (Node.js, same hardware): Hono handles ~300,000 req/s vs Express at ~65,000 req/s.

Deploy to Cloudflare Workers

bash
pnpm create cloudflare my-api --template hono
cd my-api
typescript
// src/index.ts
import { Hono } from "hono";
import { cors } from "hono/cors";
import { logger } from "hono/logger";

type Bindings = {
  DB: D1Database;
  BUCKET: R2Bucket;
};

const app = new Hono<{ Bindings: Bindings }>();

app.use("*", logger());
app.use("/api/*", cors({ origin: "https://yoursite.com" }));

app.get("/api/posts", async (c) => {
  const posts = await c.env.DB.prepare("SELECT * FROM posts ORDER BY created_at DESC").all();
  return c.json(posts.results);
});

export default app;
bash
wrangler deploy

Built-In Middleware

Hono ships middleware for the most common needs out of the box:

typescript
import { jwt } from "hono/jwt";
import { rateLimiter } from "hono/rate-limiter";
import { zValidator } from "@hono/zod-validator";
import { z } from "zod";

app.use("/protected/*", jwt({ secret: process.env.JWT_SECRET! }));

const createPost = z.object({
  title: z.string().min(1),
  body: z.string(),
});

app.post("/posts", zValidator("json", createPost), async (c) => {
  const data = c.req.valid("json"); // fully typed
  return c.json({ ok: true });
});

RPC Mode for Type-Safe Clients

Hono RPC generates a type-safe client from your route definitions - no code generation step needed:

typescript
// server: api/routes.ts
const routes = app
  .get("/users", (c) => c.json({ users: [] as User[] }))
  .post("/users", zValidator("json", createUser), (c) => c.json({ id: "123" }));

export type AppType = typeof routes;

// client: lib/api.ts
import { hc } from "hono/client";
import type { AppType } from "@/api/routes";

const client = hc<AppType>("https://api.example.com");

// Fully typed  -  autocomplete works
const res = await client.users.$get();
const { users } = await res.json(); // User[]

Running on Bun and Node

typescript
// Bun
import { Hono } from "hono";
const app = new Hono();
// ... routes
export default { port: 3000, fetch: app.fetch };

// Node.js
import { serve } from "@hono/node-server";
import { Hono } from "hono";
const app = new Hono();
// ... routes
serve({ fetch: app.fetch, port: 3000 });

The same application code runs on all runtimes - just change the entry point.
