##Gin is new, will it be supported?
Yes, Gin is an internal tool of [Manu](https://github.com/manucorporat) and [Javi](https://github.com/javierprovecho) for many of our projects/start-ups. We developed it and we are going to continue using and improve it.
##Roadmap for v1.0
- [ ] Ask our designer for a cool logo
- [ ] Add tons of unit tests
- [ ] Add internal benchmarks suite
- [ ] More powerful validation API
- [ ] Improve documentation
- [ ] Add Swagger support
- [x] Stable API
- [x] Improve logging system
- [x] Improve JSON/XML validation using bindings
- [x] Improve XML support
- [x] Flexible rendering system
- [x] Add more cool middlewares, for example redis caching (this also helps developers to understand the framework).
- [x] Continuous integration
- [x] Performance improments, reduce allocation and garbage collection overhead
- [x] Fix bugs
##Gin v1. released
- [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
Obviously, you need to have Git and Go already installed to run Gin.
Run this in your terminal
1. Download and install it:
```
```sh
go get github.com/gin-gonic/gin
```
Then import it in your Go code:
2. Import it in your code:
```
```go
import "github.com/gin-gonic/gin"
```
##API Examples
#### Create most basic PING/PONG HTTP endpoint
```go
package main
import (
"net/http"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.GET("/ping", func(c *gin.Context) {
c.String(http.StatusOK, "pong")
})
// Listen and serve on 0.0.0.0:8080
r.Run(":8080")
}
```
#### Using GET, POST, PUT, PATCH, DELETE and OPTIONS
```go
func main() {
// Creates a gin router + logger and recovery (crash-free) middlewares
r := gin.Default()
// Creates a gin router with default middlewares:
// logger and recovery (crash-free) middlewares
router := gin.Default()
r.GET("/someGet", getting)
r.POST("/somePost", posting)
r.PUT("/somePut", putting)
r.DELETE("/someDelete", deleting)
r.PATCH("/somePatch", patching)
r.HEAD("/someHead", head)
r.OPTIONS("/someOptions", options)
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)
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
router.Run(":8080")
}
```

```go

User string `form:"user" binding:"required"`
Password string `form:"password" binding:"required"`

####Serving static files
Use Engine.ServeFiles(path string, root http.FileSystem):
```go
func main() {
r := gin.Default()
r.Static("/assets", "./assets")
router := gin.Default()
router.Static("/assets", "./assets")
router.StaticFS("/more_static", http.Dir("my_file_system"))
router.StaticFile("/favicon.ico", "./resources/favicon.ico")
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
router.Run(":8080")
}
```
Use the following example to serve static files at top level route of your domain. Files are being served from directory ./html.
```
r := gin.Default()
r.Use(static.Serve("/", static.LocalFile("html", false)))
```
Note: this will use `httpNotFound` instead of the Router's `NotFound` handler.
####HTML rendering
Using LoadHTMLTemplates()
```go
func main() {
r := gin.Default()
r.LoadHTMLGlob("templates/*")
r.GET("/index", func(c *gin.Context) {
obj := gin.H{"title": "Main website"}
c.HTML(http.StatusOK, "index.tmpl", obj)
router := gin.Default()
router.LoadHTMLGlob("templates/*")

"title": "Main website",
})
})

r.Run(":8080")
router.Run(":8080")

#####Using layout files with templates

r.GET("/", func(c *gin.Context) {
r.SetHTMLTemplate(template.Must(template.ParseFiles(baseTemplate, "whatever.tmpl")))
c.HTML(200, "base", data)

whatever.tmpl

<h1>Hello World!</h1>
