Hono Middleware

If you're working with Hono's middleware system, this skill gives Claude the patterns for that onion-style execution model where middleware wraps around your handlers. It covers the built-in middleware collection, type-safe middleware creation with createMiddleware, and how to pass context variables between layers. The skill has decent adoption with 235 installs and passes most security audits, though Snyk flagged something. Honestly, this is one of those skills that pays off quickly if you're already in the Hono ecosystem and need Claude to help structure authentication, logging, or CORS without explaining the framework's quirks every time.

Hono Middleware Patterns

Overview

Hono provides a powerful middleware system with an "onion" execution model. Middleware processes requests before handlers and responses after handlers, enabling cross-cutting concerns like authentication, logging, and CORS.

Key Features:

Onion-style execution order
Type-safe middleware creation with createMiddleware
25+ built-in middleware
Context variable passing between middleware
Async/await support throughout

When to Use This Skill

Use Hono middleware when:

Adding authentication/authorization
Implementing CORS for cross-origin requests
Adding request logging or timing
Compressing responses
Rate limiting API endpoints
Validating requests before handlers

Middleware Basics

Inline Middleware

import { Hono } from 'hono'

const app = new Hono()

// Simple logging middleware
app.use('*', async (c, next) => {
  console.log(`[${c.req.method}] ${c.req.url}`)
  await next()
})

// Path-specific middleware
app.use('/api/*', async (c, next) => {
  const start = Date.now()
  await next()
  const ms = Date.now() - start
  c.header('X-Response-Time', `${ms}ms`)
})
