Decorator driven declarative framework to assist in creating large applications and manage beans

Project description

FXQuants Core

Fxquants core for python is a declarative based IOC framework for helping to build large applications in python.

Due to the way in which Python loads packages IOC frameworks are not as popular as for example in java. For example you could just use a flat file and declare instances inside of it them import it as required.

However there is still great value in employing the design patterns many developers are familiar with, and (IMHO) more useful is the declarative configuration-less nature that is used in modern versions of spring-boot allowing a developer to include at the point of code the intended purpose for a class. Defining these categories with the code allows a developer to focus on the problem domain, and less about how any given framework injects such dependencies.

The fxq series of python libraries look to take some of the best features of the Sping IOC framework and Spring boot annotations and port them as Decorators on top of a managed IOC container.

Getting Started

Create a class i.e. ComponentExample and decorate it with @Component, this will trigger an instance of this component to be registered with the IOC container and it can be pulled out with the decorator method Autowired (python doesnt currently support decorator syntax on fields so simply call the method itself, specifying either the bean name, or expected type)

import logging

format = "[%(asctime)s] [%(levelname)s] [%(name)s] - %(message)s"
logging.basicConfig(format=format, level=logging.DEBUG)

from fxq.core.beans.factory.annotation import Autowired
from fxq.core.stereotype import Component

class ComponentExample:
    def __init__(self): = "1"

    def __repr__(self):
        return "ComponentExample instance %s - ID:%s" % (hash(self),

if __name__ == '__main__':
    component_example = Autowired(type=ComponentExample)
    same_component = Autowired(name="component_example")
    same_component_again = Autowired(name="component_example", type=ComponentExample)
