Prompting Playbook for Hono

• Specify your target runtime ('Hono on Cloudflare Workers', 'Hono on Bun', 'Hono on Node.js') for platform-specific patterns
• Mention 'Hono' explicitly rather than just describing an Express-like API to avoid getting Express code instead
• Include 'with Zod validator middleware' when requesting validated endpoints to get Hono's built-in zValidator pattern
• When requesting type-safe API clients, ask for 'Hono RPC with hc client' to get end-to-end typed client generation
• Specify 'Cloudflare Workers Bindings' (KV, D1, R2) when targeting Cloudflare to get correct Env type bindings in context

Patterns AI Should Follow in Hono

• Route handlers with Hono's Context object for request parsing and typed response helpers
• Zod validator middleware with zValidator for type-safe request body, query, and parameter validation
• Middleware composition with proper async next() handling and typed context variables
• Grouped routes with .route() for modular API organization with shared prefixes
• Runtime-specific configurations for Cloudflare Workers (Bindings), Bun, Deno, and Node.js
• Hono RPC with hc() client for generating end-to-end type-safe API clients from route definitions

Typed API with Zod Validation and Middleware

A Hono API demonstrating typed routes, Zod validation middleware, JWT authentication, and grouped routes.

import { Hono } from 'hono';
import { jwt } from 'hono/jwt';
import { cors } from 'hono/cors';
import { zValidator } from '@hono/zod-validator';
import { z } from 'zod';

type Env = {
  Bindings: { DATABASE: D1Database; JWT_SECRET: string };
  Variables: { userId: string };
};

const app = new Hono<Env>();
app.use('/*', cors());

const auth = new Hono<Env>()
  .use('/*', async (c, next) => {
    const jwtMiddleware = jwt({ secret: c.env.JWT_SECRET });
    return jwtMiddleware(c, next);
  })
  .use('/*', async (c, next) => {
    const payload = c.get('jwtPayload');
    c.set('userId', payload.sub);
    await next();
  });

const CreatePostSchema = z.object({
  title: z.string().min(1).max(200),
  content: z.string().min(10),
  tags: z.array(z.string()).max(5).optional(),
});

const posts = new Hono<Env>()
  .get('/', async (c) => {
    const { results } = await c.env.DATABASE
      .prepare('SELECT * FROM posts ORDER BY created_at DESC LIMIT 20')
      .all();
    return c.json({ posts: results });
  })
  .post('/',
    zValidator('json', CreatePostSchema),
    async (c) => {
      const data = c.req.valid('json');
      const userId = c.get('userId');
      const result = await c.env.DATABASE
        .prepare('INSERT INTO posts (title, content, author_id) VALUES (?, ?, ?)')
        .bind(data.title, data.content, userId)
        .run();
      return c.json({ id: result.meta.last_row_id }, 201);
    }
  );

app.route('/api/posts', auth).route('/api/posts', posts);
export default app;
