Why Hono Is the Fast, Lightweight Alternative to Nest.js for Backend Projects
This article introduces the Hono web framework, highlighting its ultra‑fast RegExpRouter, tiny bundle size, multi‑runtime support, rich middleware ecosystem, and excellent TypeScript experience, then walks through common use cases, routing, request handling, responses, JSX rendering, and validation with code examples.
The market already offers many Node.js backend libraries and frameworks; the author previously used Nest.js, which is feature‑rich but often overkill for small projects due to its heavy abstraction.
Discovering Hono revealed several advantages:
Ultra‑fast 🚀 – Hono uses a RegExpRouter that avoids linear loops for rapid routing.
Lightweight 🪶 – The hono/tiny preset is under 12 kB and has no dependencies, relying only on Web standard APIs.
Multi‑runtime support 🌍 – Runs on Cloudflare Workers, Fastly Compute@Edge, Deno, Bun, Lagon, AWS Lambda, and Node.js with the same code.
Feature‑rich 🔋 – Built‑in, custom, third‑party middleware and utilities cover most needs.
Great developer experience 🛠️ – A concise API with excellent TypeScript support and optional type definitions.
Use Cases
Hono is a simple web‑application framework similar to Express but without a front‑end layer. Combined with middleware, it can build large applications. Typical scenarios include:
Building web interfaces
Backend server proxy
CDN edge front‑ends
Edge applications
Base server for libraries
Full‑stack applications
Next, we start learning Hono.
Hello World
Visit the official Hono documentation for more starter information.
Set the port to change the listening port.
import { Hono } from 'hono';
const app = new Hono();
app.get('/', (c) => {
return c.text('Hello Hono!');
});
export default app;Run the command: npm run dev Access the address:
http://localhost:8787Routes
HTTP Methods
app.get('/', (c) => c.text('GET /'));
app.post('/', (c) => c.text('POST /'));
app.put('/', (c) => c.text('PUT /'));
app.delete('/', (c) => c.text('DELETE /'));Nested Routes
const apiRoutes = app
.basePath("/api")
.route("/expenses", route1)
.route("/", route2);
export const route1 = new Hono()
.post("/", async (c) => {
return c.json({});
});The basePath("/api") call adds the /api prefix to all routes.
Access the nested route at http://localhost:8787/api/expenses.
Requests
Getting Request Params and Query Strings
app.get('/posts/:id', (c) => {
const page = c.req.query('page');
const id = c.req.param('id');
return c.text(`You want see ${page} of ${id}`);
});Result example:
http://localhost:8787/posts/1?page=12Getting Request Body
app.put('/posts/:id{[0-9]+}', async (c) => {
const data = await c.req.json();
return c.json(data);
});Responses
Beyond text(), Hono provides json(), html(), notFound(), redirect(), etc., for different response types. The html() method can return JSX directly.
JSX
import type { FC } from 'hono/jsx';
const app = new Hono();
const Layout: FC = (props) => {
return (
<html>
<body>{props.children}</body>
</html>
);
};
const Top: FC<{ messages: string[] }> = (props) => {
return (
<Layout>
<h1>Hello Hono!</h1>
<ul>{props.messages.map((message) => <li>{message}!!</li>)}</ul>
</Layout>
);
};
app.get('/', (c) => {
const messages = ['Good Morning', 'Good Evening', 'Good Night'];
return c.html(<Top messages={messages} />);
});
export default app;Rename the file extension to .tsx to write JSX, similar to React.
Validator
Validators using zod and @hono/zod-validator can check that incoming requests match a defined schema.
Installation: yarn add zod @hono/zod-validator Example schema and route:
account: string; password: string;import { z } from "zod";
import { zValidator } from "@hono/zod-validator";
const loginSchema = z.object({
account: z.string(),
password: z.string(),
});
app.post(
"/login",
zValidator("json", loginSchema),
async (c) => {
const user = c.req.valid("json");
return c.json({});
}
);Refer to the Zod documentation for more details; the IDE can provide type hints for user.
