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.
**The key features of Gin are:**
- Zero allocation router
- Fast
- Middleware support
- Crash-free
- JSON validation
- Routes grouping
- Error management
- Rendering built-in
- Extendable
## Getting started
### Prerequisites
- **[Go](https://go.dev/)**: any one of the **three latest major** [releases](https://go.dev/doc/devel/release) (we test it with these).
### Getting Gin
With [Go module](https://github.com/golang/go/wiki/Modules) support, simply add the following import
```
import "github.com/gin-gonic/gin"
```
to your code, and then `go [build|run|test]` will automatically fetch the necessary dependencies.
Otherwise, run the following Go command to install the `gin` package:
```sh
$ go get -u github.com/gin-gonic/gin
```
### Running Gin
First you need to import Gin package for using Gin, one simplest example likes the follow `example.go`:
```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")
}
```
And use the Go command to run the demo:
```
# run example.go and visit 0.0.0.0:8080/ping on browser
$ go run example.go
```
### Learn more examples
#### Quick Start
Learn and practice more examples, please read 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 on the [Gin examples](https://github.com/gin-gonic/examples) repository.
## Documentation
See [API documentation and descriptions](https://godoc.org/github.com/gin-gonic/gin) for package.
All documentation is available on the Gin website.

- (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
