dix

dix 中文

dix is a dependency injection tool based on the design of dig.

The main difference between dix and dig is that dix can complete more complex dependency injection management and better dependency isolation relying on namespace, and dix can also dynamically bind objects to dependent functions, object change notifications, etc.
