-# Mux
+# Mux - A Lightweight HTTP Router for Go

-Tiny wrapper around Go's builtin http.ServeMux with easy routing methods.
+Mux is a simple, lightweight HTTP router for Go that wraps around the standard `http.ServeMux` to provide additional functionality and a more ergonomic API.

-## Example
+## Features
+
+- HTTP method-specific routing (GET, POST, PUT, DELETE, etc.)
+- Middleware support with flexible stacking
+- Route grouping for organization and shared middleware
+- RESTful resource routing
+- URL parameter extraction
+- Graceful shutdown support
+- Minimal dependencies (only uses Go standard library)
+
+## Installation
+
+```bash
+go get code.patial.tech/go/mux
+```
+
+## Basic Usage

 ```go
 package main

 import (
-	"log/slog"
+	"fmt"
 	"net/http"

-	"gitserver.in/patialtech/mux"
+	"code.patial.tech/go/mux"
 )

 func main() {
-	// create a new router
-	r := mux.NewRouter()
+	// Create a new router
+	router := mux.NewRouter()

-	// you can use any middleware that is: "func(http.Handler) http.Handler"
-	// so you can use any of it
-	// - https://github.com/gorilla/handlers
-	// - https://github.com/go-chi/chi/tree/master/middleware
-
-	// add some root level middlewares, these will apply to all routes after it
-	r.Use(middleware1, middleware2)
-
-	// let's add a route
-	r.Get("/hello", func(w http.ResponseWriter, r *http.Request) {
-		w.Write([]byte("i am route /hello"))
-	})
-	// r.Post(pattern string, h http.HandlerFunc)
-	// r.Put(pattern string, h http.HandlerFunc)
-	// ...
-
-	// you can inline middleware(s) to a route
-	r.
-		With(mwInline).
-		Get("/hello-2", func(w http.ResponseWriter, r *http.Request) {
-			w.Write([]byte("i am route /hello-2 with my own middleware"))
-		})
-
-	// define a resource
-	r.Resource("/photos", func(resource *mux.Resource) {
-		// rails style resource routes
-		// GET       /photos
-		// GET       /photos/new
-		// POST      /photos
-		// GET       /photos/:id
-		// GET       /photos/:id/edit
-		// PUT 		 /photos/:id
-		// PATCH 	 /photos/:id
-		// DELETE    /photos/:id
-		resource.Index(func(w http.ResponseWriter, r *http.Request) {
-			w.Write([]byte("all photos"))
-		})
-
-		resource.New(func(w http.ResponseWriter, r *http.Request) {
-			w.Write([]byte("upload a new pohoto"))
-		})
+	// Define a simple route
+	router.GET("/", func(w http.ResponseWriter, r *http.Request) {
+		fmt.Fprint(w, "Hello, World!")
 	})

-	// create a group of few routes with their own middlewares
-	r.Group(func(grp *mux.Router) {
-		grp.Use(mwGroup)
-		grp.Get("/group", func(w http.ResponseWriter, r *http.Request) {
-			w.Write([]byte("i am route /group"))
-		})
-	})
-
-	// catches all
-	r.Get("/", func(w http.ResponseWriter, r *http.Request) {
-		w.Write([]byte("hello there"))
-	})
-
-	// Serve allows graceful shutdown, you can use it
-	r.Serve(func(srv *http.Server) error {
-		srv.Addr = ":3001"
-		// srv.ReadTimeout = time.Minute
-		// srv.WriteTimeout = time.Minute
-
-		slog.Info("listening on http://localhost" + srv.Addr)
-		return srv.ListenAndServe()
-	})
-}
-
-func middleware1(h http.Handler) http.Handler {
-	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-		slog.Info("i am middleware 1")
-		h.ServeHTTP(w, r)
-	})
-}
-
-func middleware2(h http.Handler) http.Handler {
-	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-		slog.Info("i am middleware 2")
-		h.ServeHTTP(w, r)
-	})
-}
-
-func mwInline(h http.Handler) http.Handler {
-	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-		slog.Info("i am inline middleware")
-		h.ServeHTTP(w, r)
-	})
-}
-
-func mwGroup(h http.Handler) http.Handler {
-	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-		slog.Info("i am group middleware")
-		h.ServeHTTP(w, r)
-	})
+	// Start the server
+	http.ListenAndServe(":8080", router)
 }
 ```
+
+## Routing
+
+Mux supports all HTTP methods defined in the Go standard library:
+
+```go
+router.GET("/users", listUsers)
+router.POST("/users", createUser)
+router.PUT("/users/{id}", updateUser)
+router.DELETE("/users/{id}", deleteUser)
+router.PATCH("/users/{id}", partialUpdateUser)
+router.HEAD("/users", headUsers)
+router.OPTIONS("/users", optionsUsers)
+router.TRACE("/users", traceUsers)
+router.CONNECT("/users", connectUsers)
+```
+
+## URL Parameters
+
+Mux supports URL parameters using curly braces:
+
+```go
+router.GET("/users/{id}", func(w http.ResponseWriter, r *http.Request) {
+	id := r.PathValue("id")
+	fmt.Fprintf(w, "User ID: %s", id)
+})
+```
+
+## Middleware
+
+Middleware functions take an `http.Handler` and return an `http.Handler`. You can add global middleware to all routes:
+
+```go
+// Logging middleware
+func loggingMiddleware(next http.Handler) http.Handler {
+	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+		fmt.Printf("[%s] %s\n", r.Method, r.URL.Path)
+		next.ServeHTTP(w, r)
+	})
+}
+
+// Add middleware to all routes
+router.Use(loggingMiddleware)
+```
+
+## Route Groups
+
+Group related routes and apply middleware to specific groups:
+
+```go
+// API routes group
+router.Group(func(api *mux.Router) {
+	// Middleware only for API routes
+	api.Use(authMiddleware)
+
+	// API routes
+	api.GET("/api/users", listUsers)
+	api.POST("/api/users", createUser)
+})
+```
+
+## RESTful Resources
+
+Easily define RESTful resources:
+
+```go
+router.Resource("/posts", func(r *mux.Resource) {
+	r.Index(listPosts)    // GET /posts
+	r.Show(showPost)      // GET /posts/{id}
+	r.Create(createPost)  // POST /posts
+	r.Update(updatePost)  // PUT /posts/{id}
+	r.Destroy(deletePost) // DELETE /posts/{id}
+	r.New(newPostForm)    // GET /posts/new
+})
+```
+
+## Graceful Shutdown
+
+Use the built-in graceful shutdown functionality:
+
+```go
+router.Serve(func(srv *http.Server) error {
+	srv.Addr = ":8080"
+	return srv.ListenAndServe()
+})
+```
+
+## Custom 404 Handler
+
+can be tried like this
+
+```go
+router.GET("/", func(writer http.ResponseWriter, request *http.Request) {
+    if request.URL.Path != "/" {
+        writer.WriteHeader(404)
+        writer.Write([]byte(`not found, da xiong dei !!!`))
+        return
+    }
+})
+```
