Mini Observer

A redux-like implementation of the observer pattern in JavaScript

This necessarily implements the most fundamental api of the core of redux.

Usage

npm install --save @changyan/mini-observer

import { createStore } from '@changyan/mini-observer'

const store = createStore(reducer, initState)

The design philosophy of reducer is essentially the same as redux, that is, pure function and immutable.

API

• createStore(reducer, initState): create a singleton store instance.
• store.subscribe(func): takes a function as a callback whenever the store dispatches an action. Returns a token of the subscriber.
• store.removeSubscriber(token): unsubscribe the subscriber
• store.clearAllSubscribers(): remove all the subscribers
• store.dispatch(action): action should at least have a key, type, though it's not required
