📄 Description

What is this Python project?

Dependency Injector is a dependency injection microframework for Python. It was designed to be unified, developer-friendly tool that helps to implement dependency injection design pattern in formal, pretty, Pythonic way.

Dependency Injector framework key features are:

Easy, smart, pythonic style.
Obvious, clear structure.
Extensibility and flexibility.
High performance.
Memory efficiency.
Thread safety.
Documentation.
Semantic versioning.

Dependency Injector containers and providers are implemented as C extension types using Cython.

Example code:

"""Example of dependency injection in Python."""

import logging
import sqlite3

import boto3

import example.main
import example.services

import dependency_injector.containers as containers
import dependency_injector.providers as providers


class Core(containers.DeclarativeContainer):
    """IoC container of core component providers."""

    config = providers.Configuration('config')

    logger = providers.Singleton(logging.Logger, name='example')


class Gateways(containers.DeclarativeContainer):
    """IoC container of gateway (API clients to remote services) providers."""

    database = providers.Singleton(sqlite3.connect, Core.config.database.dsn)

    s3 = providers.Singleton(
        boto3.client, 's3',
        aws_access_key_id=Core.config.aws.access_key_id,
        aws_secret_access_key=Core.config.aws.secret_access_key)


class Services(containers.DeclarativeContainer):
    """IoC container of business service providers."""

    users = providers.Factory(example.services.UsersService,
                              db=Gateways.database,
                              logger=Core.logger)

    auth = providers.Factory(example.services.AuthService,
                             db=Gateways.database,
                             logger=Core.logger,
                             token_ttl=Core.config.auth.token_ttl)

    photos = providers.Factory(example.services.PhotosService,
                               db=Gateways.database,
                               s3=Gateways.s3,
                               logger=Core.logger)


class Application(containers.DeclarativeContainer):
    """IoC container of application component providers."""

    main = providers.Callable(example.main.main,
                              users_service=Services.users,
                              auth_service=Services.auth,
                              photos_service=Services.photos)

What's the difference between this Python project and similar ones?

Enumerate comparisons.

Provides clear and simple structure: Containers -> Providers.
Use Python language features, deeply follow Pythonic style and Zen of Python.
Does NOT provide @inject decorator (or any other way of monkey-patching) that pollutes the code. Instead of this, provides feature of clean overriding of providers.
Very fast, implemented using Cython.
