Gin is a web framework written in Go. It features a martini-like API with performance that is up to 40 times faster thanks to httprouter. If you need performance and good productivity, you will love Gin.

Gin's key features are:

  • Zero allocation router
  • Speed
  • Middleware support
  • Crash-free
  • JSON validation
  • Route grouping
  • Error management
  • Built-in rendering
  • Extensible

Getting started

Prerequisites

Gin requires Go version 1.21 or above.

Getting Gin

With Go's module support, go [build|run|test] automatically fetches the necessary dependencies when you add the import in your code:

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

Alternatively, use go get:

go get -u github.com/gin-gonic/gin

Running Gin

A basic example:

package main

import (
  "net/http"

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

func main() {
  r := gin.Default()
  r.GET("/ping", func(c *gin.Context) {
    c.JSON(http.StatusOK, gin.H{
      "message": "pong",
    })
  })
  r.Run() // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080")
}

To run the code, use the go run command, like:

$ go run example.go

Then visit 0.0.0.0:8080/ping in your browser to see the response!

  • (1): Total Repetitions achieved in constant time, higher means more confident result
  • (2): Single Repetition Duration (ns/op), lower is better
  • (3): Heap Memory (B/op), lower is better
  • (4): Average Allocations per Repetition (allocs/op), lower is better
