Dependency injection lib for python
To define the classes that should be injected and stored as bean use decorator @component
@component
class A: # A instance will be created and stored in context
pass
@component
class B:
a: A # In this case an instance of A will be chosen from context and injected in B
@component
class C:
b: B
def __init__(self, a: A): # And here an instance of A will also be chosen from context
self.b = B() # and injected in B, but created manually
self.b.a = a
Then build the dependency grap using command build_dependency_graph
After that you can get ready components with get_component_from_context function
print(get_component_from_context(C)) # This will print <__main__.C object at 0x0...>
