How to expose/access a data store like Redux within a cypress test?

问题 The Cypress docs say you can Expose data stores (like in Redux) so you can programmatically alter the state of your application directly from your test code. I also watched a course on testing by Mr. Kent C. Dodds where he mentions a redux store could be initialized with existing data in Cypress (before or within tests, not sure) I went through pretty much all the docs and googled and I just can't find any references or examples of actually doing this other than it being mentioned as one of

No need for state in React components if using Redux and React-Redux?

问题 Managing state with React only I understand that if you're creating an application using React only, you will end up managing all of your state within different React components you create. Managing state with React and Redux If you decide to use Redux in combination with React, you can then move all of the state from each of your React components into the overall Redux application state. Each component that requires a slice of the Redux application state can then hook into the state via

问题 Firstly, I'm working with React Native. I'm getting a data from Firebase and want to write to store (by Redux) quickly. But It doesn't work. You can find my all of codes below: Function: async getTumData (uid) { const {selectedGroupDetail, getSelectedGroupDetail} = this.props; var yeniGrupDetayi = {}; await firebase.database().ref("/groups/"+uid).once('value').then( function(snapshot){ yeniGrupDetayi = {...snapshot.val(), uid: uid}; }).catch(e => console.log(e.message)); console.log(

why we cannot pass boolean value as props in React , it always demands string to be passed in my code

问题 Even though I have applied propType validation, my editor throws an error on when passing boolean value for the hasvacancy prop. Here is what I'm seeing: Error: 'SyntaxError: JSX value should be either an expression or a quoted JSX text' I know I am passing a string type value for 'hasvacancy' prop but what do I need to do so I can pass a boolean or other data types via the prop. import React from 'react'; import { render } from 'react-dom'; class VacancySign extends React.Component{ render()

TypeScript struggles with Redux containers

问题 I'm having some trouble figuring out how to properly type Redux containers. Consider a simple presentational component that might look like this: interface MyProps { name: string; selected: boolean; onSelect: (name: string) => void; } class MyComponent extends React.Component<MyProps, {}> { } From the perspective of this component all props are required. Now I want to write a container that pulls all these props out of state: function mapStateToProps(state: MyState) { return { name: state.my

Accessing other parts of the state, when using combined reducers

由 天大地大妈咪最大 提交于 2019-12-30 00:54:53
问题 NB : This is a question, very similar to Redux; accessing other parts... but it has nothing to do with Router :( thus cannot be solved same way When I reduce one part of the state, I "feel" like I need to access other parts as well. I admit that I just might "misfeel" the core principals of the Redux, or have flaws in my app's architecture. My current solution would be to modify github:combineReducers.js's code: var finalState = mapValues(finalReducers, (reducer, key) => { var

在上篇文章中， 基于react的nextjs服务端渲染框架学习使用 学习了解了一些关于nextjs的东西，并做了一个小demo，这篇文章将对上篇文章做一个补充，在nextjs中引入redux 安装 // 安装redux相关依赖 yarn add redux redux-saga react-redux // 安装next.js对于redux的封装依赖包 yarn add next-redux-wrapper next-redux-saga yarn add redux react-redux 创建目录及文件 创建redux文件夹，并在下面创建index.js,actions,reducers,rootSaga.js文件 1、redux/index.js 初始化store import { createStore, applyMiddleware } from 'redux'; import createSagaMiddleware from 'redux-saga'; import rootSaga from './rootSaga'; import rootReducer from './reducers'; export function initializeStore(initialState){ // 创建一个 Saga middleware const
