Injecta
Dependency Injection (DI) Container written in Python. Main component of the Pyfony Framework.
Installation
$ pip install injecta
Simple container initialization
(The following steps are covered in the ContainerInitializerTest)
To start using Injecta, create a simple config.yaml
file to define your DI services:
parameters:
api:
endpoint: 'https://api.mycompany.com'
services:
mycompany.api.ApiClient:
arguments:
- '@mycompany.api.Authenticator'
mycompany.api.Authenticator:
class: mycompany.authenticator.RestAuthenticator
arguments:
- '%api.endpoint%'
- '%env(API_TOKEN)%'
Then, initialize the container:
from injecta.container.ContainerBuilder import ContainerBuilder
from injecta.config.YamlConfigReader import YamlConfigReader
from injecta.container.ContainerInitializer import ContainerInitializer
config = YamlConfigReader().read('/path/to/config.yaml')
containerBuild = ContainerBuilder().build(config)
container = ContainerInitializer().init(containerBuild)
Use container.get()
to finally retrieve your service:
from mycompany.api.ApiClient import ApiClient
apiClient = container.get('mycompany.api.ApiClient')
apiClient.get('/foo/bar')
