Benchmarks will likely not be supported since the program runs in a sandboxed … Hi Guys we are going to build two Sci-Fi based Dev-Environments using CSS 3D and React that are geared towards focused development projects related to full-stack web interfaces and back-ends with PHP Python NodeJs and GoLang. There first interface is a cube that can be rotated to a certain panel of choice. Handler is a simple interface to a WebSocket browser client. It checks if Origin header is valid URL by default. You might want to verify websocket.Conn.Config().Origin in the func. If you use Server instead of Handler, you could call websocket.Origin and check the origin in your Handshake func.
