    "github.com/gin-contrib/cors"
    "github.com/gin-contrib/sessions"
    "github.com/gin-contrib/gzip"
)

func main() {
    r := gin.Default()
    
    // Use CORS middleware
    r.Use(cors.Default())
    
    // Use Gzip compression
    r.Use(gzip.Gzip(gzip.DefaultCompression))
    
    // Setup cookie-based sessions
    store := cookie.NewStore([]byte("secret"))
    r.Use(sessions.Sessions("mysession", store))
    
    // Routes
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    
    r.Run(":8080")
}

Extension Libraries​

Several libraries extend Gin with additional functionality:

Contributing to Gin​

How to Contribute​

Contributing to Gin is a great way to improve the framework and build your reputation:

  1. Find an issue to work on or create a new one
  2. Fork the repository
  3. Create a branch for your changes
  4. Make your changes with appropriate tests
  5. Submit a pull request

Code of Conduct​

The Gin community follows the Go Community Code of Conduct. Be respectful and professional when interacting with community members.

Real-World Example: Creating a Community Resource​

Let's say you've created a useful middleware for Gin and want to share it with the community. Here's how you might approach it:

  1. Develop your middleware with thorough documentation
  2. Create unit tests
  3. Publish on GitHub with a clear README
  4. Share with the community
go
// example of a simple rate limiter middleware
package ratelimit

import (
    "net/http"
    "sync"
    "time"

    "github.com/gin-gonic/gin"
)

// RateLimiter implements a basic IP-based rate limiting middleware
func RateLimiter(limit int, within time.Duration) gin.HandlerFunc {
    type client struct {
        count    int
        lastSeen time.Time
    }
    
    var (
        clients = make(map[string]*client)
        mu      sync.Mutex
    )
    
    return func(c *gin.Context) {
        // Get client IP
        clientIP := c.ClientIP()
        
        mu.Lock()
        defer mu.Unlock()
        
        // Get or create client record
        cli, exists := clients[clientIP]
        if !exists {
            clients[clientIP] = &client{count: 0, lastSeen: time.Now()}
            cli = clients[clientIP]
        }
        
        // Reset count if outside time window
        if time.Since(cli.lastSeen) > within {
            cli.count = 0
            cli.lastSeen = time.Now()
        }
        
        // Check if over limit
        if cli.count >= limit {
            c.AbortWithStatusJSON(http.StatusTooManyRequests, gin.H{
                "error": "rate limit exceeded",
            })
            return
        }
        
        // Increment count and proceed
        cli.count++
        c.Next()
    }
}

After creating it, you could:

  1. Share it on GitHub
  2. Post about it on Go forums
  3. Create a tutorial explaining its use
  4. Submit it to the gin-contrib organization if it's broadly useful
