golang tcp server framework ... would like to be

👍 ggogio

ggogio is a lightweight tcp server framework ... world like to be. It aims for simple use and lightness, maybe.

😶‍🌫️ how to use

1. Create a sample chatting client.

type SampleClient struct {
	server  *ggogio.Server
	session *ggogio.Session
}

func (s *SampleClient) Init(server *ggogio.Server, session *ggogio.Session) error {
	s.server = server
	s.session = session

	sessions := s.server.Query(func(session *ggogio.Session) bool {
		return s.session != session
	})
	for _, session := range sessions {
		session.Write([]byte(fmt.Sprintf("%s joined. \n", s.session.Addr)))
	}

	return nil
}

func (s *SampleClient) OnLoop() {
	data := s.session.Read()
	sessions := s.server.Query(func(session *ggogio.Session) bool {
		return s.session != session
	})
	for _, session := range sessions {
		session.Write(data)
	}
}

func (s *SampleClient) Close() {
	sessions := s.server.Query(func(session *ggogio.Session) bool {
		return s.session != session
	})
	for _, session := range sessions {
		session.Write([]byte(fmt.Sprintf("%s left. \n", s.session.Addr)))
	}
}

2. Create SampleClient factory.

type SampleFactory struct {
}

func (s SampleFactory) Create() ggogio.Client {
	return new(SampleClient)
}

3. Run server!

import (
	"log"

	"github.com/atgane/ggogio"
)

func main() {
	addr := ":10000"
	s := ggogio.NewServer(addr, SampleFactory{})
	err := s.Listen()
	if err != nil {
		log.Fatal(err)
	}
}

4. connect with telnet

telnet localhost 10000
