What are the cons of deep copying state on each reducer call in Redux application?

由 烂漫一生 提交于 2021-02-10 05:33:09
问题 Are there any side effects of doing a deep copy of state on the appReducer in a Redux application each time a reducer function is called? I'm asking because the Immutable Update Pattern docs for Redux state that to update a nested object on state, you should shallow copy the nested property and update it. I'm curious what the side effects would be for just doing a deep copy on state on every action call. Here is some pseudo code for example export default function appReducer(state =

Handling Redux Saga result in view from which action call originates

问题 I'm new to Redux Saga, coming from Redux Thunk. In some situations, I need to know whether an API call fails or succeeds from inside the view from which I called the action. With Redux Thunk, I would do something like the following. My component and action creator would look like this: class MyComponent extends Component { componentDidMount() { this.props.actions.fetchItems() .then(result => { if (result.status === 'OK') { console.log('Request succeeded, take particular action in this view')

React Redux onBlur event not firing in Safari and Firefox

由 纵然是瞬间 提交于 2021-02-08 10:16:48
问题 This seems to work perfectly in Chrome and Edge. I have a tooltip that needs to pop up onClick of the button, and then disappear onBlur. For some reason the onBlur event does not fire at all on Safari or Firefox. I've tried logging to the console in handleBlur and it does not get that far, it is as if onBlur does not exist in this context. class Tooltip extends Component { componentWillUnmount() { this.closeActiveTooltip(); } handleKeyPress = (event) => { if (event.keyCode === 27) { // Esc

问题 I have a higher order component which uses the location.search prop provided by React Router to construct a queryParams object and pass it as a prop to its wrapped component. function withQueryParams(WrappedComponent) { return (props) => { const queryParams = myUtils.parseParams(props.location.search); // props.location provided by React Router const newProps = { ...props, queryParams: queryParams } return <WrappedComponent {...newProps} /> } } export default withQueryParams And I'd use it
