Simple Dependency Injection for python

Project description

CNS Dependency Injection is a very simple way to store and inject services into your software.

It looks like this for Flask (dumb example, but you should get the point):

from di.helpers import get_service, add_service
from di.decorator import service, inject
from flask import Flask

app = Flask(__name__)
add_service('router', app.route)

@service('adder')
def adder(*args):
  sum = 0
  for arg in args:
    sum += arg
  return sum

router = get_service('router')

@router('/adds')
def adds():
  sum = get_service('adder')([1,2,3])
  return "hello " + repr(sum)

get_service('app').run()

If you are going to @inject into a class, do it on the __init__ function. @service can be used with classes or functions.
