# Gin Web Framework <img align="right" width="159px" src="https://raw.githubusercontent.com/gin-gonic/logo/master/color.png"> [](https://travis-ci.org/gin-gonic/gin) [](https://codecov.io/gh/gin-gonic/gin) [](https://goreportcard.com/report/github.com/gin-gonic/gin) [](https://godoc.org/github.com/gin-gonic/gin) [](https://gitter.im/gin-gonic/gin?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) Gin is a web framework written in Go (Golang). It features a martini-like API with much better performance, up to 40 times faster thanks to [httprouter](https://github.com/julienschmidt/httprouter). If you need performance and good productivity, you will love Gin.  ```sh # assume the following codes in example.go file $ cat example.go ``` ```go package main import "github.com/gin-gonic/gin" func main() { r := gin.Default() r.GET("/ping", func(c *gin.Context) { c.JSON(200, gin.H{ "message": "pong", }) }) r.Run() // listen and serve on 0.0.0.0:8080 } ``` ``` # run example.go and visit 0.0.0.0:8080/ping on browser $ go run example.go ``` ## 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** | **30000** | **48375** | **0** | **0** BenchmarkAce_GithubAll | 10000 | 134059 | 13792 | 167 BenchmarkBear_GithubAll | 5000 | 534445 | 86448 | 943 BenchmarkBeego_GithubAll | 3000 | 592444 | 74705 | 812 BenchmarkBone_GithubAll | 200 | 6957308 | 698784 | 8453 BenchmarkDenco_GithubAll | 10000 | 158819 | 20224 | 167 BenchmarkEcho_GithubAll | 10000 | 154700 | 6496 | 203 BenchmarkGocraftWeb_GithubAll | 3000 | 570806 | 131656 | 1686 BenchmarkGoji_GithubAll | 2000 | 818034 | 56112 | 334 BenchmarkGojiv2_GithubAll | 2000 | 1213973 | 274768 | 3712 BenchmarkGoJsonRest_GithubAll | 2000 | 785796 | 134371 | 2737 BenchmarkGoRestful_GithubAll | 300 | 5238188 | 689672 | 4519 BenchmarkGorillaMux_GithubAll | 100 | 10257726 | 211840 | 2272 BenchmarkHttpRouter_GithubAll | 20000 | 105414 | 13792 | 167 BenchmarkHttpTreeMux_GithubAll | 10000 | 319934 | 65856 | 671 BenchmarkKocha_GithubAll | 10000 | 209442 | 23304 | 843 BenchmarkLARS_GithubAll | 20000 | 62565 | 0 | 0 BenchmarkMacaron_GithubAll | 2000 | 1161270 | 204194 | 2000 BenchmarkMartini_GithubAll | 200 | 9991713 | 226549 | 2325 BenchmarkPat_GithubAll | 200 | 5590793 | 1499568 | 27435 BenchmarkPossum_GithubAll | 10000 | 319768 | 84448 | 609 BenchmarkR2router_GithubAll | 10000 | 305134 | 77328 | 979 BenchmarkRivet_GithubAll | 10000 | 132134 | 16272 | 167 BenchmarkTango_GithubAll | 3000 | 552754 | 63826 | 1618 BenchmarkTigerTonic_GithubAll | 1000 | 1439483 | 239104 | 5374 BenchmarkTraffic_GithubAll | 100 | 11383067 | 2659329 | 21848 BenchmarkVulcan_GithubAll | 5000 | 394253 | 19894 | 609 - (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 ## Gin v1. stable - [x] Zero allocation router. - [x] Still the fastest http router and framework. From routing to writing. - [x] Complete suite of unit tests - [x] Battle tested - [x] API frozen, new releases will not break your code. ## Start using it 1. Download and install it: ```sh $ go get github.com/gin-gonic/gin ``` 2. Import it in your code: ```go import "github.com/gin-gonic/gin" ``` 3. (Optional) Import `net/http`. This is required for example if using constants such as `http.StatusOK`. ```go import "net/http" ``` ### Use a vendor tool like [Govendor](https://github.com/kardianos/govendor) 1. `go get` govendor ```sh $ go get github.com/kardianos/govendor ``` 2. Create your project folder and `cd` inside ```sh $ mkdir -p ~/go/src/github.com/myusername/project && cd "$_" ``` 3. Vendor init your project and add gin ```sh $ govendor init $ govendor fetch github.com/gin-gonic/gin@v1.2 ``` 4. Copy a starting template inside your project ```sh $ curl https://raw.githubusercontent.com/gin-gonic/gin/master/examples/basic/main.go > main.go ``` 5. Run your project ```sh $ go run main.go ``` ## Build with [jsoniter](https://github.com/json-iterator/go) Gin use `encoding/json` as default json package but you can change to [jsoniter](https://github.com/json-iterator/go) by build from other tags. ```sh $ go build -tags=jsoniter . ``` ## API Examples ### Using GET, POST, PUT, PATCH, DELETE and OPTIONS ```go func main() { // Disable Console Color // gin.DisableConsoleColor() // Creates a gin router with default middleware: // logger and recovery (crash-free) middleware router := gin.Default() router.GET("/someGet", getting) router.POST("/somePost", posting) router.PUT("/somePut", putting) router.DELETE("/someDelete", deleting) router.PATCH("/somePatch", patching) router.HEAD("/someHead", head) router.OPTIONS("/someOptions", options) // By default it serves on :8080 unless a // PORT environment variable was defined. router.Run() // router.Run(":3000") for a hard coded port } ``` ### Parameters in path ```go func main() { router := gin.Default() // This handler will match /user/john but will not match neither /user/ or /user router.GET("/user/:name", func(c *gin.Context) { name := c.Param("name") c.String(http.StatusOK, "Hello %s", name) }) // However, this one will match /user/john/ and also /user/john/send // If no other routers match /user/john, it will redirect to /user/john/ router.GET("/user/:name/*action", func(c *gin.Context) { name := c.Param("name") action := c.Param("action") message := name + " is " + action c.String(http.StatusOK, message) }) router.Run(":8080") } ``` ### Querystring parameters ```go func main() { router := gin.Default() // Query string parameters are parsed using the existing underlying request object. // The request responds to a url matching: /welcome?firstname=Jane&lastname=Doe router.GET("/welcome", func(c *gin.Context) { firstname := c.DefaultQuery("firstname", "Guest") lastname := c.Query("lastname") // shortcut for c.Request.URL.Query().Get("lastname") c.String(http.StatusOK, "Hello %s %s", firstname, lastname) }) router.Run(":8080") } ``` ### Multipart/Urlencoded Form ```go func main() { router := gin.Default() router.POST("/form_post", func(c *gin.Context) { message := c.PostForm("message") nick := c.DefaultPostFo
