IDP Authentication - Hexagonal Architecture Implementation

Project description

FastAPI

IDP Authentication hexagonal architecture implementation


Purpose

This project handles the authentication process of the Cardo platform. It is a hexagonal architecture implementation, which means that the business logic is independent of the framework used to implement the API.

Architecture

The architecture is based on the Hexagonal Architecture.

The main idea is to separate the business logic from the framework and the infrastructure.

The business logic is implemented in the domain module. This module is independent of the infrastructure.

The infrastructure is implemented infrastructure module.

The app which uses this package itself is the entry point of the application. It is the only module that depends on the framework.

Requirements

Python 3.9+

IDP Authentication requires the following to be implemented:

Installation

Since this is a private repository, you need to install the package with the following command:

pip install git+ssh://git@github.com/CardoAI/idp-authentication.git@main

Example

Usage

Inside your application container:

from dependency_injector import providers
from idp_authentication.users.di.containers import IDPApplicationContainer

idp_authentication = providers.Container(
    IDPApplicationContainer,
    config=config,
    database=database,
    app_entities_unit_of_work=app_entities_unit_of_work,
)

Extending default config

from idp_authentication.config import Config

class TestConfig(Config):
    APP_IDENTIFIER = "test"
    CONSUMER_APP_ENV = "test"
    FAUST_APP_PATH = "idp_authentication.users.tests.faust_app.app"
    TENANTS = ["default"]
    ROLES = [TEST_ROLE_1, TEST_ROLE_2]
    KAFKA_BOOTSTRAP_SERVERS = ["localhost:29092"]
    KAFKA_TOPIC = "users"
    ISOLATION_LEVEL = "SERIALIZABLE"

    class Config:
        env_file_encoding = "utf-8"
        use_enum_values = True

Configuration example

from dependency_injector import containers, providers
from idp_authentication.users.di.containers import IDPApplicationContainer


class YourTestContainer(containers.DeclarativeContainer):
    config = providers.Configuration(pydantic_settings=[TestConfig()])
    url = get_test_memory_db_uri()
    database = providers.Singleton(
        Database,
    )
    app_entities_unit_of_work = providers.Factory(
        AppEntitiesUnitOfWork,
        session=database.provided.session,
    )
    idp_authentication = providers.Container(
        IDPApplicationContainer,
        config=config,
        database=database,
        app_entities_unit_of_work=app_entities_unit_of_work,
    )

Usage example

def container():
    container = YourTestContainer()
    container.wire(packages=["idp_authentication"]) # Wire IDPAuthentication
    container.idp_authentication.start_mapper() # Start IDPAuthentication mapper
    yield container

App Entity

To declare a new AppEntity, these steps are necessary:

  • The Entity class should:
    • Inherit from the class AppEntity
    • Declare the properties idp_identifier, idp_label and optionally entity_type
    • Example:
      from idp_authentication.users.domain.entities.app_entity import AppEntity
      
      class TestEntity(AppEntity):
            @property
            def idp_identifier(self):
                return self.id
            
            @property
            def idp_label(self):
                return self.name
      
            @property
            def entity_type(self):
                return "test"
      
  • The repository of the entity should:
    • Inherit from AppEntityRepositoryPort
    • Inherit from BaseRepository to use the default implementation of the methods
    • Implement the method get_idp_identifier_attr
    • Example:
      from idp_authentication.users.domain.ports.repository import AppEntityRepositoryPort
      from idp_authentication.users.base_classes.base_repository import BaseRepository
      
      class TestEntityRepository(BaseRepository[TestEntity], AppEntityRepositoryPort):
          entity = TestEntity    
      
          def get_idp_identifier_attr(self):
              return "id"
