Quick start

NOTICE: v1.3.x is not fully compatible with v1.2.x version

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

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+}

// 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}]:

// 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:

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:

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

more please see middleware_test.go middleware tests

Use http.Handler

rux is support generic http.Handler interface middleware

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

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

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：

	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

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

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

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

package main

import (
	"log"
	"net/http"

	"github.com/gookit/rux"

}

// Uses middlewares [optional]

	}
}

}

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