dependency injection
A dependency injection framework for python.
Just like Microsoft.Extensions.DependencyInjection.
Usage
class A:
pass
class B:
def __init__(self, a: A):
assert isinstance(a, A)
import dependencyinjection as di
service = di.Services()
service.scoped(A)
service.singleton(B)
provider = service.build()
assert isinstance(provider.get(A), A)
assert isinstance(provider.get(B), B)
with provider.scope() as scoped_provider:
assert provider.get(A) is provider.get(A)
assert scoped_provider.get(B) is scoped_provider.get(B)
assert provider.get(B) is scoped_provider.get(B)
assert not (provider.get(A) is scoped_provider.get(A))
