+
+[![Go Reference](https://pkg.go.dev/badge/git.haelnorr.com/h/golib/hws.svg)](https://pkg.go.dev/git.haelnorr.com/h/golib/hws)
+
+A lightweight, opinionated HTTP web server framework for Go built on top of the standard library's `net/http`.
+
+## Features
+
+- 🚀 Built on Go 1.22+ routing patterns with method and path matching
+- 🎯 Structured error handling with customizable error pages
+- 📝 Integrated logging with zerolog via hlog
+- 🔧 Middleware support with predictable execution order
+- 🗜️ GZIP compression support
+- 🔒 Safe static file serving (prevents directory listing)
+- ⚙️ Environment variable configuration
+- ⏱️ Request timing and logging middleware
+- 💚 Graceful shutdown support
+- 🏥 Built-in health check endpoint
+
+## Installation
+
+```bash
+go get git.haelnorr.com/h/golib/hws
+```
+
+## Quick Start
+
+```go
+package main
+
+import (
+    "context"
+    "git.haelnorr.com/h/golib/hws"
+    "net/http"
+)
+
+func main() {
+    // Load configuration from environment variables
+    config, _ := hws.ConfigFromEnv()
+    
+    // Create server
+    server, _ := hws.NewServer(config)
+
+    // Define routes
+    routes := []hws.Route{
+        {
+            Path:    "/",
+            Method:  hws.MethodGET,
+            Handler: http.HandlerFunc(homeHandler),
+        },
+        {
+            Path:    "/api/users/{id}",
+            Method:  hws.MethodGET,
+            Handler: http.HandlerFunc(getUserHandler),
+        },
+    }
+
+    // Add routes and middleware
+    server.AddRoutes(routes...)
+    server.AddMiddleware()
+
+    // Start server
+    ctx := context.Background()
+    server.Start(ctx)
+
+    // Wait for server to be ready
+    <-server.Ready()
+}
+
+func homeHandler(w http.ResponseWriter, r *http.Request) {
+    w.Write([]byte("Hello, World!"))
+}
+
+func getUserHandler(w http.ResponseWriter, r *http.Request) {
+    id := r.PathValue("id")
+    w.Write([]byte("User ID: " + id))
+}
