kaiju-config-validator is designed to work with kaiju-app library to validate project configuration dictionary for a set of application service classes. It analyzes __init__ methods of services to check the input data before creating an app object.

fastjsonschema library is used for validation.

Installation

With pip and python 3.12+:

pip3 install kaiju-config-validator

How to use

The configuration process is straightforward. Use the standard application configuration process as described in the kaiju-app documentation.

from kaiju_config_validator import ConfigValidator
from kaiju_app import Application, ApplicationLoader, Configurator

loader = ApplicationLoader()
loader.service_classes[...] = ...
config = Configurator().create_configuration([...], [...])

As soon as a project config dict is produced you can pass it to the validator method along with service classes map and an application class. The validator will either raise a InvalidConfiguration or return None if everything is fine.

ConfigValidator().validate_project_config(Application, loader.service_classes, config)
