Sai

Sai is a framework for managing lifecycle and dependency of your software components. In some languages, it was called “IoC” and “Dependency Injection”. The main usecase of this framework is on medium/large scale web services.

The Sai ecosystem consists of two major concepts: System, Component. A System is a runtime unit that control lifecycles of all Components. A Component is a group of logic. A Component can depends on other Components and it can also have its own internal state.
