letgo

Let's Go.

渐进式的 go 轮子.

技能栈

结构

  • app - 应用层
  • conf - 配置层
  • store - 存储层
  • util - 工具层

app

应用层, 对外提供具体的应用程序.

常见的应用程序:

  • CLI - 命令行接口
  • API - 应用程序接口 (Rest/RPC/WebService/...)
  • Web - 网站
  • Client - 客户端程序 (PC/Mobile App)
  • ...

参数选项支持优先级：命令行参数 > 配置文件参数 > WithXXX()函数选项 > 内置默认值.

conf

配置层, 提供统一的配置操作.

常见的配置文件:

  • ini
  • xml
  • json
  • yml
  • ...

store

存储层, 对外提供持久化相关的操作, 但不暴露任何具体的数据库对象.

我们所说的持久化通常是把数据存储到某个地方, 比如:

  • memory
  • sqlite
  • oracle
  • mssql
  • mysql
  • pgsql
  • tidb
  • redis
  • ...

所以如果需要切换数据库, 可以自行调整内部实现.

这样外部导入时通常是下面这样的, 也不需要单独实例化一个操作的结构体.

import (	
	userStore "github.com/taadis/store/user"
	orderStore "github.com/taadis/store/order"
)

util

工具层, 封装一些小工具都放到这里, 方便使用.
