Nexus is a small websocket server framework.
If in json format, it sends and receives messages as shown in the tags
type Packet struct {
Type string `json:"type"`
Data string `json:"data"`
}
Using the delimited format serializes and deserializes faster by simply appending things together.
It sends and receives messages in the format:
# Format
<type_length>:<type><data>
# Examples
5:tokenTOKEN_STRING_GGGGGGGGGGGGGGGG
4:ping
4:chat{"message":"hello"}
Nexus provides a simple interface for registering a handler for each message type:
func main() {
n := nexus.NewNexus()
n.Handle("token", handleToken)
n.Handle("chat", handleChat)
http.ListenAndServe(":9090", n.Handler)
}
func handleToken(c *nexus.Client, p *nexus.Packet) {
user, err := lookupUserByToken(p.Data)
if err != nil {
// send a response here
return
}
// store the user in the client's Env for using later
c.Env["user"] = user
}
func handleChat(c *nexus.Client, p *nexus.Packet) {
if _, ok := c.Env["user"] !ok {
// unauthorized
return
}
n.All().Broadcast(p)
}Cheers! I'll add more later as I think of ways to keep it simple with websockets
