一个好用的Go项目脚手架和工具包
go install github.com/shenghui0779/yiigo/cmd/yiigo@latest
分HTTP和gRPC两种,分别可创建单应用和多应用项目
# 单应用
yiigo new demo
yiigo new demo --mod=xxx.yyy.com # 指定module名称

go get -u github.com/shenghui0779/yiigo
- xhash - 封装便于使用
- xcrypto - 封装便于使用(支持 AES & RSA)
- validator - 支持汉化和自定义规则
- 基于 Redis 的分布式锁
- 基于 sqlx 的轻量SQLBuilder
- 基于泛型的无限菜单分类层级树
- linklist - 一个并发安全的双向列表
- errgroup - 基于官方版本改良,支持并发协程数量控制
- xvalue - 用于处理
k-v
格式化的场景,如:生成签名串 等 - xcoord - 距离、方位角、经纬度与平面直角坐标系的相互转化
- timewheel - 简单实用的单层时间轮(支持一次性和多次重试任务)
- 实用的辅助方法:IP、file、time、slice、string、version compare 等
⚠️ 注意:errgroup
和timewheel
如果需要协程并发复用,请使用 👉 nightfall
⚠️ 目前支持的特性有限,复杂的SQL(如:子查询等)还需自己手写
