It was designed to be unified, developer-friendly tool that helps to implement dependency injection design pattern in formal, pretty, Pythonic way. Dependency Injector provides implementations of such popular design patterns like IoC container, Factory and Singleton. Dependency Injector providers are implemented as C extension types using Cython. .. _index: .. image:: https://img.shields.io/pypi/v/dependency_injector.svg :target: https://pypi.org/project/dependency-injector/ :alt: Latest Version .. image:: https://img.shields.io/pypi/l/dependency_injector.svg :target: https://pypi.org/project/dependency-injector/ :alt: License .. image:: https://img.shields.io/pypi/pyversions/dependency_injector.svg :target: https://pypi.org/project/dependency-injector/ :alt: Supported Python versions .. image:: https://img.shields.io/pypi/implementation/dependency_injector.svg :target: https://pypi.org/project/dependency-injector/ :alt: Supported Python implementations .. image:: https://pepy.tech/badge/dependency-injector :target: https://pepy.tech/project/dependency-injector :alt: Downloads .. image:: https://pepy.tech/badge/dependency-injector/month :target: https://pepy.tech/project/dependency-injector :alt: Downloads .. image:: https://pepy.tech/badge/dependency-injector/week :target: https://pepy.tech/project/dependency-injector :alt: Downloads .. image:: https://img.shields.io/pypi/wheel/dependency-injector.svg :target: https://pypi.org/project/dependency-injector/ :alt: Wheel .. image:: https://travis-ci.org/ets-labs/python-dependency-injector.svg?branch=master :target: https://travis-ci.org/ets-labs/python-dependency-injector :alt: Build Status .. image:: http://readthedocs.org/projects/python-dependency-injector/badge/?version=latest :target: http://python-dependency-injector.ets-labs.org/ :alt: Docs Status .. image:: https://coveralls.io/repos/github/ets-labs/python-dependency-injector/badge.svg?branch=master :target: https://coveralls.io/github/ets-labs/python-dependency-injector?branch=master :alt: Coverage Status ``Dependency Injector`` is a dependency injection framework for Python. It helps you understand and change the structure of the application. 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. .. figure:: https://raw.githubusercontent.com/wiki/ets-labs/python-dependency-injector/img/di-map.svg :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.* Explore the documentation to know more about the ``Dependency Injector``.
