:description: This article describes key features of the Dependency Injector
|
|
framework.
|
|
|
|
Key features of the ``Dependency Injector``:
|
|
|
|
- **Providers**. Provides ``Factory``, ``Singleton``, ``Callable``, ``Coroutine``, ``Object``,
|
|
``List``, ``Configuration``, ``Dependency`` and ``Selector`` providers that help assembling your
|
|
objects. See :ref:`providers`.
|
|
- **Overriding**. Can override any provider by another provider on the fly. This helps in testing
|
|
and configuring dev / stage environment to replace API clients with stubs etc. See
|
|
:ref:`provider-overriding`.
|
|
- **Configuration**. Read configuration from ``yaml`` & ``ini`` files, environment variables
|
|
and dictionaries. See :ref:`configuration-provider`.
|
|
- **Containers**. Provides declarative and dynamic containers. See :ref:`containers`.
|
|
- **Performance**. Fast. Written in ``Cython``.
|
|
- **Maturity**. Mature and production-ready. Well-tested, documented and supported.
|
|
|
|
The framework stands on two principles:
|
|
|
|
- **Explicit is better than implicit (PEP20)**.
|
|
- **Do not do any magic to your code**.
|
|
|
|
How is that 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.
|
|
|
|
The power of the framework is in a simplicity. ``Dependency Injector`` is a simple tool for the powerful concept.
