What is ``Dependency Injector``?
|
|
================================
|
|
|
|
``Dependency Injector`` is a dependency injection framework for Python.
|
|
|
|
Why do I need it?
|
|
=================
|
|
|
|
``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.
|
|
|
|

|
|
:target: https://github.com/ets-labs/python-dependency-injector
|
|
|
|
*The container is like a map of your application. You always know what depends on what.*
|
|
|
|
``Flask`` + ``Dependency Injector`` example:
|
|
|
|
.. code-block:: python
|
|
|
|
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),
|
|
],
|
|
)
|
|
|
|
|
|
