:description: Dependency Injector is a dependency injection framework
|
|
for Python. It helps to maintain you application structure.
|
|
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.

``Dependency Injector`` is a dependency injection framework for Python.
|
|
|
|
It stands on two principles:
|
|
|
|
- Explicit is better than implicit (PEP20).
|
|
- Do no magic to your code.
|
|
|
|
How does it different from the other frameworks?
|
|
|
|
- **No autowiring.** The framework does NOT do any autowiring / autoresolving of the dependencies. You need to specify everything explicitly. Because *"Explicit is better than implicit" (PEP20)*.
|
|
- **Does not pollute your code.** Your application does NOT know and does NOT depend on the framework. No ``@inject`` decorators, annotations, patching or any other magic tricks.
|
|
|
|
``Dependency Injector`` makes a simple contract with you:
|
|
|
|
- You tell the framework how to assemble your objects
|
|
- The framework does it for you
|
|
|
|
The power of the ``Dependency Injector`` is in its simplicity and straightforwardness. It is a simple tool for the powerful concept.
|
|
|
|
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.*
