import React from 'react';
import ReactDOM from 'react-dom';
import {
PureFrameRoot,
defineExtractor,
defineStateReducer,
defineView,
} from 'pure-frame';
// Step 1: create pure function component.
const ClickCount = ({ count, increase }) => (
<>

<p>
<label>Count is: </label>
<span>{count}</span>
</p>
<p>
<button onClick={increase}>Increase</button>
</p>
</>
);
// Step 2: define view, injects formulas and declares actions.
const ClickCountView = defineView({
injects: {
':count': 'count'
},
actions: {
'increase': ':increase'
}
}, ClickCount);
// Step 3: provide data (from state snapshot) for component.
defineExtractor(':count', 'count');
// Step 4: handle action from component.
defineStateReducer(':increase', state =>
state.update('count', count => count + 1));
// Step 5: Compose components.
ReactDOM.render(
<PureFrameRoot state={{ count: 0 }}>
<ClickCountView />
</PureFrameRoot>,
document.getElementById('app')
);Step 3: start
