base on Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin. # Gin Web Framework <img align="right" width="159px" src="https://raw.githubusercontent.com/gin-gonic/logo/master/color.png"> [](https://github.com/gin-gonic/gin/actions?query=branch%3Amaster) [](https://codecov.io/gh/gin-gonic/gin) [](https://goreportcard.com/report/github.com/gin-gonic/gin) [](https://pkg.go.dev/github.com/gin-gonic/gin?tab=doc) [](https://sourcegraph.com/github.com/gin-gonic/gin?badge) [](https://www.codetriage.com/gin-gonic/gin) [](https://github.com/gin-gonic/gin/releases) [](https://www.tickgit.com/browse?repo=github.com/gin-gonic/gin) Gin is a web framework written in [Go](https://go.dev/). It features a martini-like API with performance that is up to 40 times faster thanks to [httprouter](https://github.com/julienschmidt/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](https://go.dev/) version [1.21](https://go.dev/doc/devel/release#go1.21.0) or above. ### Getting Gin With [Go's module support](https://go.dev/wiki/Modules#how-to-use-modules), `go [build|run|test]` automatically fetches the necessary dependencies when you add the import in your code: ```sh import "github.com/gin-gonic/gin" ``` Alternatively, use `go get`: ```sh go get -u github.com/gin-gonic/gin ``` ### Running Gin A basic example: ```go 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: ```sh $ go run example.go ``` Then visit [`0.0.0.0:8080/ping`](http://0.0.0.0:8080/ping) in your browser to see the response! ### See more examples #### Quick Start Learn and practice with the [Gin Quick Start](docs/doc.md), 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](https://github.com/gin-gonic/examples) repository. ## Documentation See the [API documentation on go.dev](https://pkg.go.dev/github.com/gin-gonic/gin). The documentation is also available on [gin-gonic.com](https://gin-gonic.com) in several languages: - [English](https://gin-gonic.com/docs/) - [简体中文](https://gin-gonic.com/zh-cn/docs/) - [繁體中文](https://gin-gonic.com/zh-tw/docs/) - [日本語](https://gin-gonic.com/ja/docs/) - [Español](https://gin-gonic.com/es/docs/) - [한국어](https://gin-gonic.com/ko-kr/docs/) - [Turkish](https://gin-gonic.com/tr/docs/) - [Persian](https://gin-gonic.com/fa/docs/) - [Português](https://gin-gonic.com/pt/docs/) ### Articles - [Tutorial: Developing a RESTful API with Go and Gin](https://go.dev/doc/tutorial/web-service-gin) ## Benchmarks Gin uses a custom version of [HttpRouter](https://github.com/julienschmidt/httprouter), [see all benchmarks](/BENCHMARKS.md). | Benchmark name | (1) | (2) | (3) | (4) | | ------------------------------ | ---------:| ---------------:| ------------:| ---------------:| | BenchmarkGin_GithubAll | **43550** | **27364 ns/op** | **0 B/op** | **0 allocs/op** | | BenchmarkAce_GithubAll | 40543 | 29670 ns/op | 0 B/op | 0 allocs/op | | BenchmarkAero_GithubAll | 57632 | 20648 ns/op | 0 B/op | 0 allocs/op | | BenchmarkBear_GithubAll | 9234 | 216179 ns/op | 86448 B/op | 943 allocs/op | | BenchmarkBeego_GithubAll | 7407 | 243496 ns/op | 71456 B/op | 609 allocs/op | | BenchmarkBone_GithubAll | 420 | 2922835 ns/op | 720160 B/op | 8620 allocs/op | | BenchmarkChi_GithubAll | 7620 | 238331 ns/op | 87696 B/op | 609 allocs/op | | BenchmarkDenco_GithubAll | 18355 | 64494 ns/op | 20224 B/op | 167 allocs/op | | BenchmarkEcho_GithubAll | 31251 | 38479 ns/op | 0 B/op | 0 allocs/op | | BenchmarkGocraftWeb_GithubAll | 4117 | 300062 ns/op | 131656 B/op | 1686 allocs/op | | BenchmarkGoji_GithubAll | 3274 | 416158 ns/op | 56112 B/op | 334 allocs/op | | BenchmarkGojiv2_GithubAll | 1402 | 870518 ns/op | 352720 B/op | 4321 allocs/op | | BenchmarkGoJsonRest_GithubAll | 2976 | 401507 ns/op | 134371 B/op | 2737 allocs/op | | BenchmarkGoRestful_GithubAll | 410 | 2913158 ns/op | 910144 B/op | 2938 allocs/op | | BenchmarkGorillaMux_GithubAll | 346 | 3384987 ns/op | 251650 B/op | 1994 allocs/op | | BenchmarkGowwwRouter_GithubAll | 10000 | 143025 ns/op | 72144 B/op | 501 allocs/op | | BenchmarkHttpRouter_GithubAll | 55938 | 21360 ns/op | 0 B/op | 0 allocs/op | | BenchmarkHttpTreeMux_GithubAll | 10000 | 153944 ns/op | 65856 B/op | 671 allocs/op | | BenchmarkKocha_GithubAll | 10000 | 106315 ns/op | 23304 B/op | 843 allocs/op | | BenchmarkLARS_GithubAll | 47779 | 25084 ns/op | 0 B/op | 0 allocs/op | | BenchmarkMacaron_GithubAll | 3266 | 371907 ns/op | 149409 B/op | 1624 allocs/op | | BenchmarkMartini_GithubAll | 331 | 3444706 ns/op | 226551 B/op | 2325 allocs/op | | BenchmarkPat_GithubAll | 273 | 4381818 ns/op | 1483152 B/op | 26963 allocs/op | | BenchmarkPossum_GithubAll | 10000 | 164367 ns/op | 84448 B/op | 609 allocs/op | | BenchmarkR2router_GithubAll | 10000 | 160220 ns/op | 77328 B/op | 979 allocs/op | | BenchmarkRivet_GithubAll | 14625 | 82453 ns/op | 16272 B/op | 167 allocs/op | | BenchmarkTango_GithubAll | 6255 | 279611 ns/op | 63826 B/op | 1618 allocs/op | | BenchmarkTigerTonic_GithubAll | 2008 | 687874 ns/op | 193856 B/op | 4474 allocs/op | | BenchmarkTraffic_GithubAll | 355 | 3478508 ns/op | 820744 B/op | 14114 allocs/op | | BenchmarkVulcan_GithubAll | 6885 | 193333 ns/op | 19894 B/op | 609 allocs/op | - (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](https://github.com/gin-contrib). ## Uses Here are some awesome projects that are using the [Gin](https://github.com/gin-gonic/gin) web framework. - [gorush](https://github.com/appleboy/gorush): A push notification server. - [fnproject](https://github.com/fnproject/fn): A container native, cloud agnostic serverless platform. - [photoprism](https://github.com/photoprism/photoprism): Personal photo management powered by Google TensorFlow. - [lura](https://github.com/luraproject/lura): Ultra performant API Gateway with middleware. - [picfit](https://github.com/thoas/picfit): An image resizing server. - [dkron](https://github.com/distribworks/dkron): Distributed, fault tolerant job scheduling system. ## Contributing Gin is the work of hundreds of contributors.
