goim 是 非常成功的 IM ( 即时消息平台), 依赖项为 kafka ( 消息队列) + zookeeper ( 分布式扩展) + bilibili/discovery( 服务发现与均衡) , 由于 kafka / zk 在部署上与 golang 的单一可执行文件相比, 稍复杂, 加上为简化运维, 所以, 这里 fork 了 goim 并修改为 nats
- 消息队列修改为 nats + liftbridge 注: liftbridge 替代了 nats-streaming-server , 相关信息参见liftbridge介绍文章
- 日志替换为 uber-go/zap, 替换原一是因为 zap 快一点, 二是个人更为熟悉这个日志库
