나는 가장 깨끗한 것을 찾을 수있는 또 다른 대안을 제안하고 싶지만, react-redux
또는 비슷한 것이 필요합니다. 또한 그 과정에서 다른 멋진 기능을 사용하고 있습니다.
// actions.js
export const someAction = (items) => ({
type: 'SOME_ACTION',
payload: {items},
});
// Component.jsx
import {connect} from "react-redux";
const Component = ({boundSomeAction}) => (<div
onClick={boundSomeAction}
/>);
const mapState = ({otherReducer: {items}}) => ({
items,
});
const mapDispatch = (dispatch) => bindActionCreators({
someAction,
}, dispatch);
const mergeProps = (mappedState, mappedDispatches) => {
// you can only use what gets returned here, so you dont have access to `items` and
// `someAction` anymore
return {
boundSomeAction: () => mappedDispatches.someAction(mappedState.items),
}
});
export const ConnectedComponent = connect(mapState, mapDispatch, mergeProps)(Component);
// (with other mapped state or dispatches) Component.jsx
import {connect} from "react-redux";
const Component = ({boundSomeAction, otherAction, otherMappedState}) => (<div
onClick={boundSomeAction}
onSomeOtherEvent={otherAction}
>
{JSON.stringify(otherMappedState)}
</div>);
const mapState = ({otherReducer: {items}, otherMappedState}) => ({
items,
otherMappedState,
});
const mapDispatch = (dispatch) => bindActionCreators({
someAction,
otherAction,
}, dispatch);
const mergeProps = (mappedState, mappedDispatches) => {
const {items, ...remainingMappedState} = mappedState;
const {someAction, ...remainingMappedDispatch} = mappedDispatch;
// you can only use what gets returned here, so you dont have access to `items` and
// `someAction` anymore
return {
boundSomeAction: () => someAction(items),
...remainingMappedState,
...remainingMappedDispatch,
}
});
export const ConnectedComponent = connect(mapState, mapDispatch, mergeProps)(Component);
당신이 다시 사용하려는 경우 특정을 추출해야합니다 mapState
, mapDispatch
그리고 mergeProps
기능에 다른 곳에서 재사용 할 수 있지만,이 차종은 완벽하게 명확한 종속성.
