问题 I recently upgraded to react 16.2.0 from react 15.6.2 Now my application doesnt work as expected and has lot of warnings for dependancies on react 15.6.2 So for me now its not possible to upgrade all other dependencies to 16.2.0. because of the time schedule. Hence I want to downgrade to react 15.6.2 I ran following commands to install react 15.6.2 again: npm install react@^15.6.2 I am getting following error : +-- UNMET PEER DEPENDENCY react@15.6.2 invalid `-- UNMET PEER DEPENDENCY react-dom

问题 I've written a function that gets data from my firestore, filters through it, and returns data posted only by the logged-in user. The data, in this case, are gig listings: authListener() { auth().onAuthStateChanged((user) => { if (user) { this.setState( { userDetails: user }, () => axios .get( "https://us-central1-gig-fort.cloudfunctions.net/api/getGigListings" ) .then((res) => { let filteredGigs = res.data.filter((gig) => { return gig.user === this.state.userDetails.uid; }); this.setState({

问题 I have created an Ionic React app using Ionic 5 tab template. I want to pass an object from App component to tab component. Is there any way to do it ? Tab1 and Tab2 are my tab components. Note: I want this object to be used in both Tab components with two way data binding i.e. whenever that object is changed in one Tab component, it must be updated in second Tab component.I want to achieve it without using Redux or any third party library. My App component is like below: <IonApp>

问题 I've written a simple app where the remote resources are fetched inside componentDidMount functions of the components. I'm using React Router and when the route changes completely, the previous component is unmounted well then the new one is mounted. The issue is when the user is staying on the same route, but only some params are changed. In that case, the component is only updated. This is the default behaviour. But it's sometimes difficult to handle the update in all the children

问题 I'm trying to use matchPath to extract a route param from the parent container as described in https://stackoverflow.com/a/45492498/3574819 const topicMatch = matchPath(history.location.pathname, { path: '/:topic' }); When I console.log(topicMatch.params) , the object has the topic key set but if I try to access topicMatch.params.topic I get the following error: error TS2339: Property 'topic' does not exist on type '{}'. const RouterApp = withRouter<{}>( class App extends React.Component
