demessaging.backend package

Core module for generating a de-messaging backend module.

This module defines the base classes to serve a general python module as a backend module in the DASF.

The most important members are:

main([module_name])	Main function for starting a backend module from the command line.
BackendModule([root])	A base class for a backend module.
BackendFunction()	A base class for a function model.
BackendClass()	A basis for class models

Functions:

main([module_name])

Main function for starting a backend module from the command line.

demessaging.backend.main(module_name: str = '__main__', *args, **config_kws) → Type[BackendModule]

Main function for starting a backend module from the command line.

Parameters:

• doc (str) – The documentation of the object. If empty, this will be taken from the corresponding __doc__ attribute.

• registry (demessaging.config.registry.ApiRegistry) – Utilities for imports and encoders.

• template (demessaging.template.Template) – The demessaging.template.Template that is used to render the module for the generated API.

• messaging_config (Union[demessaging.config.messaging.PulsarConfig, demessaging.config.messaging.WebsocketURLConfig]) – Configuration on how to connect to the message broker.

• listen_config (demessaging.config.backend.ListenConfig) – None

• log_config (demessaging.config.logging.LoggingConfig) – Configuration for the logging.

• debug (bool) – Run the backend module in debug mode (creates more verbose error messages).

• members (List[Union[str, Callable, Type[object], Any]]) – List of members for this module

• imports (str) – Imports that should be added to the generate API module.

• json_schema_extra (Dict[str, Any]) – Any extra parameter for the JSON schema export for the function
