# Example of Router
These examples show you the usage of `router`. You can easily build a web application with it. Or you can make your own midwares such as custom logger, metrics, or any one you want.
### Basic example
This is just a quick introduction, view the [GoDoc](https://pkg.go.dev/github.com/fasthttp/router) for details.
Let's start with a trivial example:
```go
package main
import (
"fmt"
"log"
"github.com/fasthttp/router"
"github.com/valyala/fasthttp"
)
// Index is the index handler
func Index(ctx *fasthttp.RequestCtx) {
fmt.Fprint(ctx, "Welcome!\n")
}
// Hello is the Hello handler
func Hello(ctx *fasthttp.RequestCtx) {
fmt.Fprintf(ctx, "hello, %s!\n", ctx.UserValue("name"))
}
// MultiParams is the multi params handler
func MultiParams(ctx *fasthttp.RequestCtx) {
fmt.Fprintf(ctx, "hi, %s, %s!\n", ctx.UserValue("name"), ctx.UserValue("word"))
}
// QueryArgs is used for uri query args test #11:
// if the req uri is /ping?name=foo, output: Pong! foo
// if the req uri is /piNg?name=foo, redirect to /ping, output: Pong!
func QueryArgs(ctx *fasthttp.RequestCtx) {
name := ctx.QueryArgs().Peek("name")
fmt.Fprintf(ctx, "Pong! %s\n", string(name))
}
func main() {
r := router.New()
r.GET("/", Index)
r.GET("/hello/{name}", Hello)
r.GET("/multi/{name}/{word}", MultiParams)
r.GET("/ping", QueryArgs)
log.Fatal(fasthttp.ListenAndServe(":8080", r.Handler))
}
```
