# Sux
|
||||
|
||||
Static route http router that considers the request method
|
||||
|
||||
Useful for serving server-side rendered content.
|
||||
|
||||
## How
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"git.icod.de/dalu/sux"
|
||||
"io"
|
||||
"net/http"
|
||||
)
|
||||
|
||||
func main() {
|
||||
r := sux.New()
|
||||
r.GET("/", Hello)
|
||||
r.GET("/simple", Simple)
|
||||
http.ListenAndServe(":8080", r)
|
||||
}
|
||||
|
||||
func Hello(w http.ResponseWriter, r *http.Request) {
|
||||
io.WriteString(w, "hello")
|
||||
}
|
||||
|
||||
func Simple(w http.ResponseWriter, r *http.Request) {
|
||||
name := r.URL.Query().Get("name")
|
||||
io.WriteString(w, "hello "+name)
|
||||
}
|
||||
```
|
||||
|
||||
