aioredux 1.0.1

Pythonic redux

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).

Usage

@asyncio.coroutine()
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.
