Dependency Injector is a dependency injection framework for Python.
Dependency Injector helps you improve application structure.
With the Dependency Injector you keep application structure in one place.
This place is called the container. You use the container to manage all the components of the application. All the component dependencies are defined explicitly. This provides the control on the application structure. It is easy to understand and change it.
The container is like a map of your application. You always know what depends on what.
Flask + Dependency Injector example:
from dependency_injector import containers, providers
from dependency_injector.ext import flask
from github import Github
from . import services, views
class Application(containers.DeclarativeContainer):
"""Application container."""
config = providers.Configuration()
github_client = providers.Factory(
Github,
login_or_token=config.github.auth_token,
timeout=config.github.request_timeout,
)
search_service = providers.Factory(
services.SearchService,
github_client=github_client,
)
index_view = providers.Callable(
views.index,
search_service=search_service,
default_search_term=config.search.default_term,
default_search_limit=config.search.default_limit,
)
app = providers.Factory(
flask.create_app,
name=__name__,
routes=[
flask.Route('/', view_provider=index_view),
],
