**Gin** is a high-performance HTTP web framework written in Golang (Go). Gin has a #key# martini: a legacy web framework in Go #key#-like API and claims to be up to 40 times faster.  

Gin allows you to build web applications and microservices in Go. It contains a set of commonly used functionalities (e.g., routing, middleware support, rendering, etc.) that reduce boilerplate code and make it simpler to build web applications.

# Installation

1. Download and install:  
```ps
go get -u github.com/gin-gonic/gin
```
2. Import it into your code:  
```go
import "github.com/gin-gonic/gin"
```

# Example

Let's create a simple web server using Gin. `gin.Default()` creates a Gin router with default middleware: logger and #key# recovery:crash-free #key# middleware.  
Next, we make a handler using `router.GET(path, handle)`, where `path` is the relative path,​ and `handle` is the handler function that takes `*gin.Context` as an argument. The handler function serves a JSON response with a status of $200$.  
Finally, we start the router using `router.Run()` that, by default, listens on port $8080$.

package main
import "github.com/gin-gonic/gin"

func main() {

	// Creates a gin router with default middleware
	router  := gin.Default()

	// A handler for GET request on /example
	router.GET("/example", func(c *gin.Context) {
		
		c.JSON(200, gin.H{
			"message": "example",
		}) // gin.H is a shortcut for map[string]interface{}
	})
	router.Run() // listen and serve on port 8080
}
