react-redux

问题 OP EDIT: If anyone else comes across this: the app was created using create-react-app, which limits importing to within the src folder. However if you upgrade react-scripts to v1.0.11 it does let you access package.json. I'm trying to get the version number from package.json in my app. I've already tried these suggestions, but none of them have worked as I can't access package.json from outside the src folder (might be due to React, I'm new to this). Moving package.json into src then means I

问题 I am building a Instagram clone backed by firebase and redux. I have a Profile screen in which i render the posts that the user has made. The problem with this is the posts does not get updated, I was using FlatList component and found that we need to use a extraData prop. This is my Profile.tsx (Profile screen) : import React, { useState, useEffect } from "react"; import { View, Text, StyleSheet, Image, FlatList, Alert } from "react-native"; import db, { auth } from "../../firebase"; import

问题 I am migrating my small React Native project from pure Javascript to Typescript. While it went well so far, I now have problems with Redux. The reducer I'm struggling with is radioButtonSelectedReducer . In the application, there are two radio buttons. If the first one is clicked, it gives string "itemOne" and if the second one is clicked, it gives string "itemTwo". Therefore, radioButtonSelected must be of type string, I thought. But it gives the error: radioButtonSelected: string; --> "The

问题 I have a working image-upload front/back-end code working. Now I would like to be able to GET the image from server after it is uploaded. The problem is that the images must be behind an authenticated route, where user has to pass jwt token in header or body.

问题 I'm new to React. I want to capture all react uncaught and unexpected errors/warnings and i would like to log the errors to an external api. I know its possible by Try Catch method but I'm planning to have it globally so that other developer need not to write the code each and every time. I tried window.onerror/addEventListener('error', function(e){} which only captures the Javascript errors but not react errors. This is similar to following post How do I handle exceptions?. But the solution
