问题 I use thunk middleware and pass initial state to React, but the problem is that React state is not saved when I visit other links. After successfully logged in, it's supposed to render dashboard. User must be redirected to dashboard(which is the root path, / ) when he tries to go to /login page. Should i use redux-router too? I omitted some of code, but it almost looks like below. init.js I passed store to Provider import { Provider } from 'react-redux'; import configureStore from './store

问题 I'm working on a game. Originally, the user was in a single dungeon, with properties: // state { health: 95, creatures: [ {}, {} ], bigBoss: {}, lightIsOn: true, goldReward: 54, // .. you get the idea } Now there are many kingdoms, and many dungeons, and we may want to fetch this data asynchronously. Is it better to represent that deeply-nested structure in the user's state, effectively caching all the other possible dungeons when they are loaded, and every time we want to update a property

问题 I am trying to filter my array object list and then trying to display in the ListView with new DataSource. However, the list is not getting filtered. I know that my filter function works correctly. ( I checked it in the console.log ) I am using Redux to map my state to prop. And then trying to filter the prop. Is this the wrong way? Here is my code: /*global fetch:false*/ import _ from 'lodash'; import React, { Component } from 'react'; import { ListView, Text as NText } from 'react-native';

问题 I'm trying to work out the cleanest way to load the initial state of my Redux stores when it comes from API calls. I understand that the typical way of providing the initial state is to generate it server-side on page load, and provide it to Redux createStore() as a simple object. However, I'm writing an app that I'm planning on packaging up in Electron and so this doesn't work. The best that I've been able to come up with so far is to fire an action immediately after creating the store that

问题 I am building a React/Redux app using the redux-thunk middleware to create and handle Ajax requests. I have a particular thunk that is fired pretty often, and I would like to cancel any previously started Ajax requests before firing a new one. Is this possible? 回答1: One approach would be to mark those requests as canceled by giving them random id and checking its status before handling the result. The way to do this is to assign random id for this call in your first dispatch (inside the thunk

问题 I'm getting this error on my index.tsx. Property ' REDUX_DEVTOOLS_EXTENSION_COMPOSE ' does not exist on type 'Window'. Here is my index.tsx code: import * as React from 'react'; import * as ReactDOM from 'react-dom'; import App from './App'; import './index.css'; import registerServiceWorker from './registerServiceWorker'; import { Provider } from 'react-redux'; import { createStore, compose, applyMiddleware } from 'redux'; import rootReducer from './store/reducers'; import thunk from 'redux

问题 I am trying to put my React app on the Heroku. The whole project include one API (express) and one client (ReactJS). I have put my API on heroku. But when I put my client on Heroku, it shows build succeeded. But when I open it, it shows Invalid Host header . I google this problem and many people tell me to configure the HOST. But they are using webpack. I build this with create-react-app and I run it by npm start . I want to know how to solve this problem in most easy way. Thanks. 回答1: If for

问题 I'm learning Redux and I can see people storing all kinds of information into the state and doing all kinds of different operations through reducers. But is Redux secure or is there any known vulnerabilities of using Redux? If there are then are there any best practices that I can follow to secure the state? 回答1: Maybe let's change the question - does keeping any data in the client side is safe? And answer is no. Any kind of secret data should never exist in the front side. State management

问题 I am using Axios JS library for sending post json request. but I am not receiving anything at the server. Here is my code const dt = JSON.stringify({"data":{"value":"gdfg1df2g2121dgfdg"}}); const request = axios.post(url, {dt}); I need to send post raw body in json format . 回答1: By default axios uses Json for posting data so you don't need to stringify your data. The problem could be that you're doing that. Could you try doing the post without it and check if it works? Also you don't need the
