Testing flux stores with mocha, chai and sinon

三世轮回 提交于 2019-12-06 07:52:21
问题 I'm trying to test Flux stores with Mocha, Chai and Sinon. I've been searching for examples but couldn't find enough information to make my tests work. I've tried many things but I'm quite blocked. This is what I have now. Source MyStore.js var AppDispatcher = require('../dispatcher/AppDispatcher'); var EventEmitter = require('events').EventEmitter; var MyStoreConstants = require('../constants/MyConstants'); var assign = require('object-assign'); var CHANGE_EVENT = 'change'; var _results = []

React Flux: what's the point of actions?

↘锁芯ラ 提交于 2019-12-06 06:41:47
In Flux , what is the point of using actions , instead of just letting the component publish directly to the dispatcher ? What is it that I can't do without actions ? The action creators decouple the component from the dispatcher. You could replace the dispatcher and related pieces with something else and the components would not need to change. 来源: https://stackoverflow.com/questions/29677779/react-flux-whats-the-point-of-actions

Sharing data between components in React

空扰寡人 提交于 2019-12-06 06:19:23
I'm developing an app using Meteor and React as view engine Consider this diagram: React hide component from another example I need to change C2 component state when C4 button click event is fired. Since they don't have a direct relationship i cannot access to C2 state directly from C4. Another example would be submit a form from a Component and get the data (value of input fields) declared in another Component. I know there are some possible hacks to solve this problem (e.g. Meteor Session, pass data through each component, flux-based Action/Dispatcher). React docs recommends to use event

SpringCloud Gateway拦截器遇到的小坑汇总

很多朋友在使用SpringCloudGateway的时候可能都碰到过以下几个问题 SpringCloudGateway中如何读取Post请求体 private BodyInserter getBodyInserter(ServerWebExchange exchange) { ServerRequest serverRequest = new DefaultServerRequest(exchange); Mono<String> modifiedBody = serverRequest.bodyToMono(String.class) .flatMap(body -> { //这里的body就是Post的请求体 }); BodyInserter bodyInserter = BodyInserters.fromPublisher(modifiedBody, String.class); return bodyInserter; } SpringCloudGateway中Post请求参数只能读取一次 这是因为Gateway默认使用的是SpringWebflux,解决这个问题需要容重新构造一个request来替换原先的request HttpHeaders headers=new HttpHeaders(); CachedBodyOutputMessage outputMessage

Structuring the store of a localized react / redux app

柔情痞子 提交于 2019-12-05 22:00:17
I am having a hard time structure my data in a localized blogging app. My app is displaying posts, with embedded pictures (one-to-many), in three languages (English, French and Russian). The visitor can choose its locale. The editors can edit the localized versions of their posts in the three languages. For the moment, the structure of my store looks like this: { articles: { en: { 1: { id: 1, title: "my first title", body: "my first body", picture_ids: [1, 2, 3]}, 2: { id: 2, title: "my second title", body: "my second body", picture_ids: [1, 4, 5]}, 3: { id: 3, title: "my third title", body:

Spring 5 响应式编程

要点 Reactor 是一个运行在 Java8 之上的响应式流框架,它提供了一组响应式风格的 API 除了个别 API 上的区别,它的原理跟 RxJava 很相似 它是第四代响应式框架,支持操作融合,类似 RxJava 2 Spring 5 的响应式编程模型主要依赖 Reactor RxJava 回顾 Reactor 是第四代响应式框架,跟RxJava 2 有些相似。Reactor 项目由Pivotal 启动,以响应式流规范、Java8 和ReactiveX 术语表为基础。它的设计是Reactor 2(上一个主要版本)和RxJava 核心贡献者共同努力的结果。 在之前的同系列文章 RxJava 实例解析 和 测试RxJava 里,我们已经了解了响应式编程的基础:数据流的概念、Observable 类和它的各种操作以及通过工厂方法创建静态和动态的Observable 对象。 Observable 是事件的源头,Observer 提供了一组简单的接口,并通过订阅事件源来消费 Observable 的事件。Observable 通过 onNext 向 Observer 通知事件的到达,后面可能会跟上 onError 或 onComplete 来表示事件的结束。 RxJava 提供了 TestSubscriber 来测试 Observable,TestSubscriber 是一个特别的

How to handle one-to-many relationships in Flux stores

一个人想着一个人 提交于 2019-12-05 15:56:59
问题 I'm just starting to use flux (with redux for now) and am wondering how relationships are supposed to be handled. For an example we can use Trello that has boards with columns that contains cards. One approach would be to have one store/reducer for boards and have all the data in it there but that means some very fat stores since they would have to contain all the actions for columns and cards as well. Another approach i've seen is separating nested resources into for example BoardStore,

提升不止一点点,Dubbo 3.0 预览版详细解读,还愣着干啥啊?进来啊

Dubbo 自 2011 年 10 月 27 日开源后,已被许多非阿里系的公司使用,其中既有当当网、网易考拉等互联网公司,也不乏中国人寿、青岛海尔等大型传统企业。 自去年 12 月开始,Dubbo 3.0 便已正式进入开发阶段,并备受社区和广大 Dubbo 用户的关注,本文将为您详细解读3.0 预览版的新特性和新功能。 下面先解答一下两个有意思的与 Dubbo 相关的疑问。 · 为什么 Dubbo 一开源就是 2.0 版本?之前是否存在 1.0 版本? 笔者曾做过 Dubbo 协议的适配兼容,Dubbo 确实存在过 1.x 版本,而且从协议设计和模型设计上都与 2.0 的开源版本协议是完全不一样的。下图是关于 Dubbo 的发展路径: · 阿里内部正在使用 Dubbo 开源版本吗? 是的,非常确定,当前开源版本的 Dubbo 在阿里巴巴被广泛使用,而阿里的电商核心部门是用的 HSF2.2 版本,这个版本是兼容了 Dubbo 使用方式和 Remoting 协议。当然,我们现在正在做 HSF2.2 的升级,直接依赖开源版本的 Dubbo 来做内核的统一。所以,Dubbo 是得到大规模线上系统验证的分布式服务框架,这一点毋容置疑。 Dubbo 3.0 预览版的要点 Dubbo 3.0 在设计和功能上的新增支持和改进,主要是以下四方面: · Dubbo 内核之 Filter 链的异步化

Why should addChangeListener be in componentDidMount instead of componentWillMount?

百般思念 提交于 2019-12-05 04:12:19
I saw this line as an answer to another question on here: "componentWillMount should be componentDidMount, or else you'll leak event emitters in node." and I don't really understand it. Can someone explain with more detail? More info: Building a react application with flux, as part of the initial render, a child component computes some data. Ideally, after this data is computed, I would like to call an action that updates the store's state with a portion of this new data. Normally, updating the store's state emits a change event that causes a re-render. However, because the change listener isn

What is best practice to communicate between React components and services?

别说谁变了你拦得住时间么 提交于 2019-12-05 03:32:45
问题 Instead of using flux/redux architecture, how react components should communicate with services? For example: There is a container having few representational (react) components: ChatBox - enables to read/write messages AvatarBox with password changer - which enables to change user's password News stream - lists news and apply filter to them Thinking of them as resources representation, I want each of them to access Microservice API by itself (getting or updating data). Is this correct? It
