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.
