Websocket-TCP Relay is a simple relay that allows to connect to a TCP server via a websocket connection. It is built with Fiber.
This creates a middleware relay that connects to a TCP server on localhost:4222 and relays the data between the websocket and the TCP server.
app := fiber.New()
app.Use(logger.New())
app.Get("/ws", relay.New(relay.Config{}, "localhost:4222"))
if err := app.Listen(":8080"); err != nil {
return err
}
