Pythonic Redux

Pythonic Redux using asyncio. aioredux provides a predictable state container with the following goal: “[Redux] helps you write applications that behave consistently, run in different environments …, and are easy to test” (from the Redux documentation).

This package requires Python 3.4 or higher

Usage

import asyncio
import aioredux

 async def go():
     initial_state = {
         'todos': (),
     }

     def add_todo(text):
         return {'type': 'ADD_TODO', 'text': text}

     def reducer(state, action):
         if action['type'] == 'ADD_TODO':
             todos = state['todos'] + (action['text'],)
             return {'todos': todos}
         return state

     store = yield from aioredux.create_store(reducer, initial_state)
     yield from store.dispatch(add_todo('todo text'))
     print(store.state['todos'])

 asyncio.get_event_loop().run_until_complete(go())

Implementation notes

  • dispatch is marked as async although in most cases it functions like a plain Python function returning a Future. This is done to allow for cases where dispatch performs a more complicated set of (async) actions.
  • A Pythonic version of redux-thunk is also included.
