 Reconnecting WebSocket is a websocket client based on [gorilla/websocket](https://github.com/gorilla/websocket) that will automatically reconnect if the connection is dropped.
+
+## Basic example
+
+```go
+package main
+
+import (
+	"context"
+	"github.com/loeffel-io/recws"
+	"log"
+	"time"
+)
+
+func main() {
+	ctx, cancel := context.WithCancel(context.Background())
+	ws := recws.RecConn{}
+	ws.Dial("wss://echo.websocket.org", nil)
+
+	go func() {
+		time.Sleep(2 * time.Second)
+		cancel()
+	}()
+
+	for {
+		select {
+		case <-ctx.Done():
+			go ws.Close()
+			log.Printf("Websocket closed %s", ws.GetURL())
+			return
+		default:
+			if !ws.IsConnected() {
+				log.Printf("Websocket disconnected %s", ws.GetURL())
+				continue
+			}
+
+			if err := ws.WriteMessage(1, []byte("Incoming")); err != nil {
+				log.Printf("Error: WriteMessage %s", ws.GetURL())
+				return
+			}
+
+			_, message, err := ws.ReadMessage()
+			if err != nil {
+				log.Printf("Error: ReadMessage %s", ws.GetURL())
+				return
+			}
+
+			log.Printf("Success: %s", message)
+		}
+	}
+}
+```
