infrago

infrago 是框架核心运行时（module: github.com/infrago/infra）。

包定位

  • 类型：核心主包（运行时）
  • 作用：统一管理模块生命周期、配置加载、模块装配与调用入口

主要功能

  • 运行流程（infra.Run()）：Load -> Config -> Setup -> Open -> Start -> Wait -> Stop -> Close
  • 生命周期（模块接口）：Setup -> Open -> Start -> Stop -> Close
  • 统一启动：infra.Run()
  • 统一调用：infra.Invoke()
  • 自定义配置：infra.Setting()
  • 模块挂载：模块通过 infra.Mount(module) 接入

最小可运行示例

package main

import (
    _ "github.com/infrago/http"
    _ "github.com/infrago/log"
    "github.com/infrago/infra"
)

func main() {
    infra.Run()
}

[infrago]
name = "demo"
profile = "dev"

[http]
port = 8100

[log]
driver = "default"

[setting]
