independency 1.1

Dependency injection container

Independency

Independency is a DI container library. Unlike many other Python DI containers Independency operates in the local scope. It's inspired by punq, so the API is very similar.

Independency supports generics and other specific typings.

Installation

pip install independency

Examples

Let's begin with a simple example.

import requests

from independency import Container, ContainerBuilder


class Config:
    def __init__(self, url: str):
        self.url = url


class Getter:
    def __init__(self, config: Config):
        self.config = config

    def get(self):
        return requests.get(self.config.url)


def create_container() -> Container:
    builder = ContainerBuilder()
    builder.singleton(Config, Config, url='http://example.com')
    builder.singleton(Getter, Getter)
    return builder.build()


def main():
    container = create_container()
    getter: Getter = container.resolve(Getter)
    print(getter.get().status_code)


if __name__ == '__main__':
    main()
