Gin Web Framework

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 1.23 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!

Quick Start

Learn and practice with the Gin Quick Start, which includes API examples and builds tag.

Examples

A number of ready-to-run examples demonstrating various use cases of Gin are available in the Gin examples repository.

Documentation

See the API documentation on go.dev.

The documentation is also available on gin-gonic.com in several languages:

(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

Middleware

You can find many useful Gin middlewares at gin-contrib and gin-gonic/contrib.
