## GoDoc

- [godoc for github](https://pkg.go.dev/github.com/gookit/rux?tab=doc)

## Install

```bash
go get github.com/gookit/rux
```

## Quick start

```go
package main

import (
"github.com/gookit/rux"
)

func main() {
r := rux.New()

// Add Routes:
r.GET("/", func(c *rux.Context) {
c.Text(200, "hello")
})
r.GET("/hello/{name}", func(c *rux.Context) {
c.Text(200, "hello " + c.Param("name"))
})
r.POST("/post", func(c *rux.Context) {
c.Text(200, "hello")
})
// add multi method support for an route path
r.Add("/post[/{id}]", func(c *rux.Context) {
if c.Param("id") == "" {
// do create post
c.Text(200, "created")
return
}

id := c.Params.Int("id")
// do update post
c.Text(200, "updated " + fmt.Sprint(id))
}, rux.POST, rux.PUT)

// Start server
r.Listen(":8080")
// can also
// http.ListenAndServe(":8080", r)
}
```

## Route Group

```go
r.Group("/articles", func() {
r.GET("", func(c *rux.Context) {
c.Text(200, "view list")
})
r.POST("", func(c *rux.Context) {
c.Text(200, "create ok")
})
r.GET(`/{id:\d+}`, func(c *rux.Context) {
c.Text(200, "view detail, id: " + c.Param("id"))
})
})
```

## Path Params

You can add the path params like: `{id}` Or `{id:\d+}`

```go
// can access by: "/blog/123"
r.GET(`/blog/{id:\d+}`, func(c *rux.Context) {
c.Text(200, "view detail, id: " + c.Param("id"))
})
```

optional params, like `/about[.html]` or `/posts[/{id}]`:

```go
// can access by: "/blog/my-article" "/blog/my-article.html"
r.GET(`/blog/{title:\w+}[.html]`, func(c *rux.Context) {
c.Text(200, "view detail, id: " + c.Param("id"))
})

r.Add("/posts[/{id}]", func(c *rux.Context) {
if c.Param("id") == "" {
// do create post
c.Text(200, "created")
return
}

id := c.Params.Int("id")
// do update post
c.Text(200, "updated " + fmt.Sprint(id))
}, rux.POST, rux.PUT)
```

## Use Middleware

rux support use middleware, allow:

- global middleware
- group middleware
- route middleware

**Call priority**: `global middleware -> group middleware -> route middleware`

Examples:

```go
package main

import (
"fmt"

"github.com/gookit/rux"
)

func main() {
r := rux.New()

// add global middleware
r.Use(func(c *rux.Context) {
// do something ...
})

// add middleware for the route
route := r.GET("/middle", func(c *rux.Context) { // main handler
c.WriteString("-O-")
}, func(c *rux.Context) { // middle 1
c.WriteString("a")
c.Next() // Notice: call Next()
c.WriteString("A")
// if call Abort(), will abort at the end of this middleware run
// c.Abort()
})

// add more by Use()
route.Use(func(c *rux.Context) { // middle 2
c.WriteString("b")
c.Next()
c.WriteString("B")
})

// now, access the URI /middle
// will output: ab-O-BA
}
```

- **Call sequence**: `middle 1 -> middle 2 -> main handler -> middle 2 -> middle 1`
- **Flow chart**:

```text
+-----------------------------+
| middle 1 |
| +----------------------+ |
| | middle 2 | |
start | | +----------------+ | | end
------->| | | main handler | | |--->----
| | |________________| | |
| |______________________| |
|_____________________________|
```

## Use http.Handler

rux is support generic `http.Handler` interface middleware

> You can use `rux.WrapHTTPHandler()` convert `http.Handler` as `rux.HandlerFunc`

```go
package main

import (
"net/http"

"github.com/gookit/rux"
// here we use gorilla/handlers, it provides some generic handlers.
"github.com/gorilla/handlers"
)

func main() {
r := rux.New()

// create a simple generic http.Handler
h0 := http.HandlerFunc(func (w http.ResponseWriter, r *http.Request) {
w.Header().Set("new-key", "val")
})

r.Use(rux.WrapHTTPHandler(h0), rux.WrapHTTPHandler(handlers.ProxyHeaders()))

r.GET("/", func(c *rux.Context) {
c.Text(200, "hello")
})
// add routes ...

// Wrap our server with our gzip handler to gzip compress all responses.
http.ListenAndServe(":8000", handlers.CompressHandler(r))
}
```

## More Usage

### Static Assets

```go
package main

import (
"embed"
"net/http"

"github.com/gookit/rux"
)

//go:embed static
var embAssets embed.FS

func main() {
r := rux.New()

// one file
r.StaticFile("/site.js", "testdata/site.js")

// allow any files in the directory.
r.StaticDir("/static", "testdata")

// file type limit in the directory
r.StaticFiles("/assets", "testdata", "css|js")

// go 1.16+: use embed assets. access: /embed/static/some.html
r.StaticFS("/embed", http.FS(embAssets))
}
```

### Name Route

In `rux`, you can add a named route, and you can get the corresponding route instance(`rux.Route`) from the router according to the name.

Examples:

```go
r := rux.New()

// Method 1
myRoute := rux.NewNamedRoute("name1", "/path4/some/{id}", emptyHandler, "GET")
r.AddRoute(myRoute)

// Method 2
rux.AddNamed("name2", "/", func(c *rux.Context) {
c.Text(200, "hello")
})

// Method 3
r.GET("/hi", func(c *rux.Context) {
c.Text(200, "hello")
}).NamedTo("name3", r)

// get route by name
myRoute = r.GetRoute("name1")
```

### Redirect

redirect to other page

```go
r.GET("/", func(c *rux.Context) {
c.AbortThen().Redirect("/login", 302)
})

// Or
r.GET("/", func(c *rux.Context) {
c.Redirect("/login", 302)
c.Abort()
})

r.GET("/", func(c *rux.Context) {
c.Back()
c.Abort()
})
```

### Cookies

you can quick operate cookies by `FastSetCookie()` `DelCookie()`

> Note: You must set or delete cookies before writing BODY content

```go
r.GET("/setcookie", func(c *rux.Context) {
c.FastSetCookie("rux_cookie2", "test-value2", 3600)
c.SetCookie("rux_cookie", "test-value1", 3600, "/", c.Req.URL.Host, false, true)
c.WriteString("hello, in " + c.URL().Path)
})

r.GET("/delcookie", func(c *rux.Context) {
val := ctx.Cookie("rux_cookie") // "test-value1"
c.DelCookie("rux_cookie", "rux_cookie2")
})
```

### Multi Domains

> code is refer from `julienschmidt/httprouter`

```go
package main

import (
"log"
"net/http"

"github.com/gookit/rux"
)

type HostSwitch map[string]http.Handler

// Implement the ServeHTTP method on our new type
func (hs HostSwitch) ServeHTTP(w http.ResponseWriter, r *http.Request) {
// Check if a http.Handler is registered for the given host.
// If yes, use it to handle the request.
if router := hs[r.Host]; router != nil {
router.ServeHTTP(w, r)
} else {
// Handle host names for which no handler is registered
http.Error(w, "Forbidden", 403) // Or Redirect?
}
}

func main() {
// Initialize a router as usual
router := rux.New()
router.GET("/", Index)
router.GET("/hello/{name}", func(c *rux.Context) {})

// Make a new HostSwitch and insert the router (our http handler)
// for example.com and port 12345
hs := make(HostSwitch)
hs["example.com:12345"] = router

// Use the HostSwitch to listen and serve on port 12345
log.Fatal(http.ListenAndServe(":12345", hs))
}
```

### RESETFul Style

```go
package main

import (
"log"
"net/http"

"github.com/gookit/rux"
)

type Product struct {
}

// Uses middlewares [optional]
func (Product) Uses() map[string][]rux.HandlerFunc {
return map[string][]rux.HandlerFunc{
// function name: handlers
"Delete": []rux.HandlerFunc{
handlers.HTTPBasicAuth(map[string]string{"test": "123"}),
handlers.GenRequestID(),
},
}
}

// all products [optional]
func (p *Product) Index(c *rux.Context) {
// do something
}

// create product [optional]
func (p *Product) Create(c *rux.Context) {
// do something
}

// save new product [optional]
func (p *Product) Store(c *rux.Context) {
// do something
}

// show product with {id} [optional]
func (p *Product) Show(c *rux.Context) {
// do something
}

// edit product [optional]
func (p *Product) Edit(c *rux.Context) {
// do something
}

// save edited product [optional]
func (p *Product) Update(c *rux.Context) {
// do something
}

// delete product [optional]
func (p *Product) Delete(c *rux.Context) {
// do something
}

func main() {
router := rux.New()

// methods Path Action Route Name
// GET /product index product_index
// GET /product/create create product_create
// POST /product store product_store
// GET /product/{id} show product_show
// GET /product/{id}/edit edit product_edit
// PUT/PATCH /product/{id} update product_update
// DELETE /product/{id} delete product_delete
// resetful style
router.Resource("/", new(Product))

log.Fatal(http.ListenAndServe(":12345", router))
}
```

### Controller Style

```go
package main

import (
"log"
"net/http"

"github.com/gookit/rux"
)

// News controller
type News struct {
}

func (n *News) AddRoutes(g *rux.Router) {
g.GET("/", n.Index)
g.POST("/", n.Create)
g.PUT("/", n.Edit)
}

func (n *News) Index(c *rux.Context) {
// Do something
}

func (n *News) Create(c *rux.Context) {
// Do something
}

func (n *News) Edit(c *rux.Context) {
// Do something
}

func main() {
router := rux.New()

// controller style
router.Controller("/news", new(News))

log.Fatal(http.ListenAndServe(":12345", router))
}
```

### Build URL

```go
package main

import (
"log"
"net/http"

"github.com/gookit/rux"
)

func main() {
// Initialize a router as usual
router := rux.New()
router.GET(`/news/{category_id}/{new_id:\d+}/detail`, func(c *rux.Context) {
var u = make(url.Values)
u.Add("username", "admin")
u.Add("password", "12345")

b := rux.NewBuildRequestURL()
// b.Scheme("https")
// b.Host("www.mytest.com")
b.Queries(u)
b.Params(rux.M{"{category_id}": "100", "{new_id}": "20"})
// b.Path("/dev")
// println(b.Build().String())

println(c.Router().BuildRequestURL("new_detail", b).String())
// result: /news/100/20/detail?username=admin&password=12345
// get current route name
if c.MustGet(rux.CTXCurrentRouteName) == "new_detail" {
// post data etc....
}
}).NamedTo("new_detail", router)

// Use the HostSwitch to listen and serve on port 12345
log.Fatal(http.ListenAndServe(":12345", router))
}
```
