Redux as a Render Prop

Counter.jsx

import StoreProvider from './StoreProvider';

const increment = { type: '@counter/increment' };
const decrement = { type: '@counter/decrement' };

const initialState = { count: 0 };

const reducer = (state = initialState, action) => {
    switch (action.type) {
        case increment.type:
            return {
                count: state.count + 1,
            };
        case decrement.type:
            return {
                cound: state.count - 1,
            };
    }

    return state;
}

export default () => (
    <StoreProvider
        reducer={reducer}
        render={({ state, dispatch }) => (
            <div>
                <h1>Count: {state.count}</h1>
                <button onClick={() => dispatch(increment)}>Increment</button>
                <button onClick={() => dispatch(decrement)}>Decrement</button>
            </div>
        )}
    />
)

StoreProvider.js

import React from 'react';

export default class StoreProvider extends React.Component {
    constructor(props) {
        super(props);
        this.dispatch = this.createDispatch(props.reducer);
        this.state = props.reducer(this.state, { type: '@store/init' });
    }

    createDispatch(reducer) {
        return (action) => {
            const state = reducer(this.state, action);
            this.setState(() => state);
            return state;
        };
    }

    componentWillReceiveProps({ reducer }) {
        if (reducer !== this.props.reducer) {
            this.dispatch = this.createDispatch(reducer);
        }
    }

    render() {
        return this.props.render({
            dispatch: this.dispatch,
            state: this.state,
        });
    }
}

I am not sure if this can break something or pure convention but a dispatcher is supposed to return the action it took as param instead of state. StoreProvider.js line 14

It would be nice to have the connect version as well, without it react redux is incomplete.
