• Request/Response Acknowledgement-Based Cycle
• Broadcast/Room Support
• Microservices Using Socket.IO
• Plugable Architecture
• App, Client, and Request Contexts

Quick Start

The following sample will start a server that responds on an "echo" endpoint and return the same message received from the client back to the client.

Server

package main

import (
  f "github.com/ambelovsky/gosf"
)

func init() {
  // Listen on an endpoint
  f.Listen("echo", func(client *f.Client, request *f.Request) *f.Message {
    return f.NewSuccessMessage(request.Message.Text)
  })
}

func main() {
  // Start the server using a basic configuration
  f.Startup(map[string]interface{}{
    "port": 9999})
}

Client

<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.2.0/socket.io.slim.js"></script>
<script>
  var socket = io.connect('ws://localhost:9999', { transports: ['websocket'] });

  socket.emit('echo', { text: 'Hello world.' }, function(response) {
    console.log(response);
  });
</script>
