Core Lib Class

core_lib.core_lib.CoreLib [source]

CoreLib class is the front of the entire library. It exposes all the “Services” your library offers by using simple Services, DataAccess, and Clients assignments to YourCoreLib class. You define your library interface.

Usage

from core_lib.core_lib import CoreLib
from core_lib.helpers.config_instances import instantiate_config
...

class YourCoreLib(CoreLib):
    def __init__(self, config: DictConfig):
        CoreLib.__init__(self)
        self.email = instantiate_config(self.config, EmailCoreLib)  # instantiate `EmailCoreLib` from config
        user_da = UserDataAccess(instantiate_config(self.config.core_lib.data.db, SqlAlchemyConnectionFactory)) 
        self.user = UserService(user_da)
        self.user_photos = UserPhotosService(user_da)        
        ...

Code Explained:

• YourCoreLib class is extending CoreLib class
• __init__ method: Services are being instantiated, such as EmailCoreLib, UserDataAccess, UserService, and UserPhotosService.
• self.email: An instance of EmailCoreLib is instantiated using instantiate_config function, passing self.config as a parameter.
• user_da: An instance of UserDataAccess is created, utilizing SqlAlchemyConnectionFactory instantiated from self.config.core_lib.data.db.
• self.user: An instance of UserService is created, passing user_da as a parameter.
• self.user_photos: An instance of UserPhotosService is created, also passing user_da as a parameter.

core_lib.core_lib.CoreLib.__init__() [source]

When extending CoreLib class call CoreLib.__init__(self) to initialize event listeners and set the core_lib_started flag to False.

class YourCoreLib(CoreLib):
  
  def __init__(self):
      CoreLib.__init__(self)
