Components

Adding components, which are instantiated classes, to the injector and injecting them in your function arguments are the most basic functionality the injector.

A small demonstration:

from component_injector import Injector

# Define a component to inject.
class MyFirstComponent:
   def __init__(self):
      print("Initializing MyFirstComponent.")

# Create an injector namespace.
injector = Injector()

# Instantiate the component and register it with the injector.
component = MyFirstComponent()
injector.register(component)

# Define a function that uses the component and connect it to
# the injector.
@injector.inject
def my_component_consumer(component: MyFirstComponent):
   print(component)

# Calling the consumer without specifying the `component`
# argument will trigger the injector to add it automatically.
my_component_consumer()
