## Features

- 🚀 **High Performance** - Hybrid routing with LRU cache for optimal speed
- 🎯 **Simple API** - Clean and intuitive API design inspired by Hono.js
- 🔧 **Middleware Support** - Flexible middleware system with onion model
- 📁 **Static File Serving** - Built-in static file server with caching
- 🔐 **Security** - Path validation and security utilities
- 📤 **File Upload** - Chunked file upload support
- 🗄️ **Database** - SQLite integration for data persistence
- 🔑 **Authentication** - Built-in auth system with JWT-like tokens

## Installation

### From VPM

```bash
v install meiseayoung.hono
```

### From GitHub

```bash
v install --git https://github.com/meiseayoung/v-hono
```

### Local Development

Clone the repository and the module will be available for import:

```bash
git clone https://github.com/meiseayoung/v-hono.git
cd v-hono
```

## Quick Start

```v
import net.http
import hono

fn main() {
    mut app := hono.Hono.new()

    app.get('/', fn (mut c hono.Context) http.Response {
        return c.text('Hello, World!')
    })

    app.get('/json', fn (mut c hono.Context) http.Response {
        return c.json('{"message": "Hello, JSON!"}')
    })

    app.get('/users/:id', fn (mut c hono.Context) http.Response {
        user_id := c.params['id'] or { 'unknown' }
        return c.json('{"user_id": "${user_id}"}')
    })

    app.listen(':3000')
}
```

## Middleware

```v
import net.http
import time
import hono

fn main() {
    mut app := hono.Hono.new()

    // Logger middleware
    app.use(fn (mut c hono.Context, next fn (mut hono.Context) http.Response) http.Response {
        start := time.now()
        response := next(mut c)
        duration := time.since(start)
        println('[${c.req.method}] ${c.path} - ${duration}')
        return response
    })

    app.get('/', fn (mut c hono.Context) http.Response {
        return c.text('Hello with middleware!')
    })

    app.listen(':3000')
}
```

## Route Grouping

```v
import net.http
import hono

fn main() {
    mut app := hono.Hono.new()

    // Create API sub-application
    mut api := hono.Hono.new()
    
    api.get('/users', fn (mut c hono.Context) http.Response {
        return c.json('[{"id": 1, "name": "Alice"}]')
    })

    api.get('/users/:id', fn (mut c hono.Context) http.Response {
        user_id := c.params['id'] or { 'unknown' }
        return c.json('{"id": ${user_id}}')
    })

    // Mount API routes under /api prefix
    app.route('/api', mut api)

    app.listen(':3000')
}
```

## Static File Serving

```v
import net.http
import hono

fn main() {
    mut app := hono.Hono.new()

    // Serve static files from ./public directory
    app.use(hono.serve_static(hono.StaticOptions{
        root: './public'
        path: '/static'
    }))

    app.listen(':3000')
}
```

## API Reference
