  • [Reduc] React Counter Example

    Before you use the React Redux bindings, learn how to create a complete simple application with just React and Redux.

    <html>
    <head>
      <meta charset="utf-8">
      <title>JS Bin</title>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/redux/3.0.4/redux.js"></script>
     <script src="https://fb.me/react-0.14.0.js"></script>
      <script src="https://fb.me/react-dom-0.14.0.js"></script>
    
    </head>
    <body>
      <div id='root'></div>
    </body>
    </html>
    const counter = (state = 0, action) => {
      switch (action.type) {
        case 'INCREMENT':
          return state + 1;
        case 'DECREMENT':
          return state - 1;
        default:
          return state;
      }
    } 
    
    const Counter = ({
      value,
      onIncrement,
      onDecrement
    }) => (
      <div>
        <h1>{value}</h1>
        <button onClick={onIncrement}>+</button>
        <button onClick={onDecrement}>-</button>
      </div>
    );
    
    const { createStore } = Redux;
    const store = createStore(counter);
    
    const render = () => {
      ReactDOM.render(
        <Counter
          value={store.getState()}
          onIncrement={() =>
            store.dispatch({
              type: 'INCREMENT'           
            })            
          }
          onDecrement={() =>
            store.dispatch({
              type: 'DECREMENT'           
            })            
          }
        />,
        document.getElementById('root')
      );
    };
    
    store.subscribe(render);
    render();

    From React 0.14, you can declear a compoment by using a function.
