Yet Another Python Dependency Injection

YAPYDI: Yet Another Python Dependency Injection

Why? Just need a simpler DI, checked some existing ones, not a fun, so developed this one.

Why DI in python? Well, it is NOT for everyone. It is always an good idea for loose coupling for user and implmentation.

How to use it

Install

pip install yapydi

Basic usage

from yapydi import enable_di, bean, injected, Injected

@bean()
def world() -> str:
    return "World"
    
@injected
def hello_world(world : str = Injected[str]):
    print("Hello {}!".format(world))

@enable_di
def main():
    hello_world()

if __name__ == "__main__":
    main()

Advanced usage

from yapydi import enable_di, bean, BeanRegistry

@bean(name="my_bean_name")
def world() -> str:
    return "World"

def hello_world():
    registry = BeanRegistry.get_instance()
    print("Hello {}!".format(registry.one_by_name("my_bean_name")))

@enable_di
def main():
    hello_world()

if __name__ == "__main__":
    main()

How does it work

Doing bean definition and injection with annotation power. @bean() annotation will get the bean to be registered. @enable_di will init the beans, and @injected will be hooked so the injection can happen. BeanRegistry is the only place for retrieve beans by name type or both.
