##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"

||||
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

||||

####Serving static files
|
||||
Use Engine.ServeFiles(path string, root http.FileSystem):
|
||||
|
||||
```go
|
||||
func main() {
|
||||
r := gin.Default()
|
||||
r.Static("/assets", "./assets")
|
||||
router := gin.Default()
|

```
|

|
||||
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.

||||

|
||||
|
||||
Using LoadHTMLTemplates()
|
