或阅读其[源代码](https://github.com/nestjs/nest)。感谢读者们！ 4 | 5 | a lightweight nodejs microservices framework 6 | 7 | ## FEATURES 8 | 9 | - [x] 模式匹配做服务间调用：略不同于 SpringCloud 服务发现（http协议、IP + PORT模式），它使用更加灵活的模式匹配（Patrun模块）原则去进行微服务间的调用，实际上是一种 RPC 实现。 10 | - [x] 接入 koa2 对C端提供 RESTFUl API 11 | - [x] 插件：更灵活编写小而微的可复用模块 12 | - [x] seneca 内置日志输出与第三方日志库比较 winston（选用） 13 | - [x] RabbitMQ 消息队列 14 | - [x] PM2：node服务部署（服务集群）、管理与监控 15 | - [x] PM2：自动化部署（命令行一键部署） 16 | - [ ] PM2 集成 docker 17 | - [ ] K8S 做服务治理 18 | - [x] 请求追踪（重建用户请求流程） 19 | - [x] 梳理 Consul 服务注册与发现基本逻辑 20 | - [x] 框架集成 node-consul 21 | - [x] mongodb 持久化存储（集成第三方） 22 | - [x] 结合 seneca 与 consul 的路由服务中间件（可支持多个相同名字服务集群路由，通过 $$version 区别） 23 | - [ ] 支持流处理（文件上传/下载等） 24 | - [ ] jenkins 自动化部署 25 | - [x] nginx 做应用层负载均衡（集成第三方） 26 | - [ ] 持续集成方案 27 | - [x] redis 缓存（集成第三方） 28 | - [ ] Apollo 提供 GraphQL 接口 29 | 30 | ~~[Introduction](https://blog.qingf.me/?p=734)~~ 31 |
