Incompose provides named and default imports:
import {withState} from 'incompose';
import withState from 'incompose/dist/withState';
import {
linkEvent
} from 'inferno';
import {
compose,
withState,
shouldUpdate
} from 'incompose';
const inc = (props) => {
props.setCount(props.count += 1);
};
const dec = (props) => {
props.setCount(props.count -= 1);
};
const Counter = (props) => (
<div>
<h1>count : {props.count}</h1>
<button onClick={linkEvent(props, dec)}>-</button>
<button onClick={linkEvent(props, inc)}>+</button>
</div>
);
/**
* with state creates 2 new props on the component props
* props.count - contains the value (1 is set as default value)
* props.setCount - contains the setter function
*/
const withCounterState = withState('count', 'setCount', 1);
/**
* should update prevents the component of re-render (shouldUpdate lifecycle hook)
* you can compare current and next props and decide whether the component
* should update or not. In this example, the counter just updates if
* props.count is even.
*/
const withUpdatePolicy = shouldUpdate((props, nextProps) => (
nextProps.count % 2 === 0
));
/**
* with compose all the extended functions are composed BEFORE Counter
* gets rendered. Please not that order matters.
*/
export default compose(
withCounterState,
withUpdatePolicy,
)(Counter);
Special thanks to all the contributors and Andrew Clark (@acdlite) for creating this amazing lib for React!
