Front-end framework based on react, redux, react-redux, react-router and redux-saga, inspired by elm and choo.
$ npm install --save dvaLet's create an count app that changes when user click the + or - button.

import { Route } from 'dva/router';
// 1. Initialize
const app = dva();
// 2. Model
app.model({
namespace: 'count',
state: 0,
reducers: {
['count/add' ](count) { return count + 1 },
['count/minus'](count) { return count - 1 },
},
});
// 3. View
const App = connect(({ count }) => ({
count
}))(function(props) {
return (
<div>
<h2>{ props.count }</h2>
<button key="add" onClick={() => { props.dispatch({type: 'count/add'})}}>+</button>
<button key="minus" onClick={() => { props.dispatch({type: 'count/minus'})}}>-</button>
</div>
);
