A type hint based dependency injection library for python language (+3.6). While there are already several DI libraries for python, this library is inspired by Java Spring and aims to provide similar interface and functionality to Java Spring.
Supports Python 3.7 and 3.8.
Super simple. Attach @component decorator to any classes which need to be injected in somewhere constructor, and attach @autowired decorator to constructors which need dependency injection.
from pytidy.decorators import component, autowired
@component
class Hello:
def say(self):
print("Hello")
class Injected:
@autowired
def __init__(self, instance: Hello):
self.instance = instance
def say_proxy(self):
self.instance.say()
a = Injected()
a.say_proxy()Also supports dataclass of Python3.7+.
from dataclasses import dataclass
from pytidy.decorators import component, autowired_cls
@component
class Hello:
def say(self):
print("Hello")
@autowired_cls
@dataclass
class Injected:
instance: Hello
def say_proxy(self):
self.instance.say()
a = Injected()
a.say_proxy()MIT
