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.
|
|
|
|
**The key features of Gin are:**
|
|
|
|
- Zero allocation router
|
|
- Fast
|
|
- Middleware support
|
|
- Crash-free
|
|
- JSON validation
|
|
- Routes grouping
|
|
- Error management
|
|
- Rendering built-in
|
|
- Extendable
|
|
|
|
For more feature details, please see the [Gin website introduction](https://gin-gonic.com/docs/introduction/).
|
|
|
|
## Getting started
|
|
|
|
### Getting Gin
|
|
|
|
The first need [Go](https://golang.org/) installed (version 1.6+ is required), then you can use the below Go command to install Gin.
|
|
|
|
```sh
|
|
$ go get -u github.com/gin-gonic/gin
|
|
```
|
|
|
|
For more installation guides such as vendor tool, please check out [Gin quickstart](https://gin-gonic.com/docs/quickstart/).
|
|
|
|
### Running Gin
|
|
|
|
First you need to import Gin package for using Gin, one simplest example likes the follow `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
|
|
}
|
|
```
|
|
|
|
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
|
|
```
|
|
|

- (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
