Nano -- 轻量级、便利、高性能基于golang的游戏服务器框架

Nano is an easy to use, fast, lightweight game server networking library for Go. It provides a core network architecture and a series of tools and libraries that can help developers eliminate boring duplicate work for common underlying logic. The goal of nano is to improve development efficiency by eliminating the need to spend time on repetitious network related programming.

Nano was designed for server-side applications like real-time games, social games, mobile games, etc of all sizes.

How to build a system with Nano

What does a Nano application look like?

The simplest "nano" application as shown in the following figure, you can make powerful applications by combining different components.

In fact, the nano application is a collection of  Component , and a component is a bundle of  Handler, once you register a component to nano, nano will register all methods that can be converted to Handler to nano service container. Service was accessed by Component.Handler, and the handler will be called while client request. The handler will receive two parameters while handling a message:

*session.Session: corresponding a client that apply this request or notify.*protocol.FooBar: the payload of the request.

While you had processed your logic, you can response or push message to the client by session.Response(payload) and session.Push('eventName', payload), or returns error when some unexpected data received.

How to build distributed system with Nano

Nano contains built-in distributed system solution, and make you creating a distributed game server easily.

See: The distributed chat demo

The Nano will remain simple, but you can perform any operations in the component and get the desired goals. You can startup a group of Nano application as agent to dispatch message to backend servers.

How to execute the asynchronous task

func (manager *PlayerManager) Login(s *session.Session, msg *ReqPlayerLogin) error { var onDBResult = func(player *Player) { manager.players = append(manager.players, player) s.Push("PlayerSystem.LoginSuccess", &ResPlayerLogin) } // run slow task in new gorontine go func() { player, err := db.QueryPlayer(msg.PlayerId) // ignore error in demo // handle result in main logical gorontine nano.Invoke(func(){ onDBResult(player) }) } return nil}
