ReactJS findDOMNode and getDOMNode are not functions

点点圈 提交于 2019-11-30 04:12:11
I'm building a web-app with ReactJS and Flux and I'm trying to get the node of my current div using the method findDOMNode and I get the next error: Uncaught TypeError: React.findDOMNode is not a function So, I tried to use getDOMNode and I get the very same error: Uncaught TypeError: React.getDOMNode is not a function I'm using npm to build the JS, the code where I use these methods: var React = require('react'); var stores = require('../stores'); var MessagesUserContainer = require('./messageusercontainer'); var ChatStore = stores.ChatStore; var owner = stores.getOwner(); var MessagesList =

How to setup Ember like computed properties in Immutablejs and Redux and Flux and React

问题 I am used to computed properties in Ember Object Model. It's a convenient way to specify computed properties that depend on other properties. Say fullName depends on firstName and lastName , I can setup computed properties as a function computeProperties and call computeProperties each time I make a change. Example: function computeFullName(state) { const fullName = state.get('firstName') + state.get('lastName'); const nextState = state.set('fullName', fullName); return nextState; } function

Flux 和 Mono 的区别

Flux 和 Mono 是 Reactor 中的两个基本概念。Flux 表示的是包含 0 到 N 个元素的异步序列。在该序列中可以包含三种不同类型的消息通知:正常的包含元素的消息、序列结束的消息和序列出错的消息。当消息通知产生时,订阅者中对应的方法 onNext(), onComplete()和 onError()会被调用。Mono 表示的是包含 0 或者 1 个元素的异步序列。该序列中同样可以包含与 Flux 相同的三种类型的消息通知。Flux 和 Mono 之间可以进行转换。对一个 Flux 序列进行计数操作,得到的结果是一个 Mono 对象。把两个 Mono 序列合并在一起,得到的是一个 Flux 对象。 来源: https://www.cnblogs.com/cag2050/p/11552278.html

Pretty Printing JSON with React

北城以北 提交于 2019-11-29 23:27:38
I'm using ReactJS and part of my app requires pretty printed JSON. I get some JSON like: { "foo": 1, "bar": 2 } , and if I run that through JSON.stringify(obj, null, 4) in the browser console, it pretty prints, but when I use it in this react snippet: render: function() { var json = this.getStateFromFlux().json; return ( <div> <JsonSubmitter onSubmit={this.onSubmit} /> { JSON.stringify(json, null, 2) } </div> ); }, it renders gross JSON that looks like "{ \"foo\" : 2, \"bar\": 2}\n" . How do I get those characters to be interpreted properly? { You'll need to either insert BR tag appropriately

What could be the downsides of using Redux instead of Flux [closed]

爷,独闯天下 提交于 2019-11-29 18:33:21
I just recently discovered Redux . It all looks good. Are there any downsides, gotcha or compromises of using Redux over Flux? Thanks Dan Abramov Redux author here! I'd like to say you're going to make the following compromises using it: You'll need to learn to avoid mutations. Flux is unopinionated about mutating data, but Redux doesn't like mutations and many packages complementary to Redux assume you never mutate the state. You can enforce this with dev-only packages like redux-immutable-state-invariant , use Immutable.js , or trust yourself and your team to write non-mutative code, but it

Why use one store per entity in the flux application architecture?

坚强是说给别人听的谎言 提交于 2019-11-29 18:18:32
问题 I am using reactjs and the flux architecture in a project I'm working on. I am a bit puzzled by how to break up nested data correctly into stores and why I should split up my data into multiple stores. To explain the problem I'll use this example: Imagine a Todo application where you have Projects. Each project has tasks and each task can have notes. The application uses a REST api to retrieve the data, returning the following response: { projects: [ { id: 1, name: "Action Required", tasks: [

is there any good Http library for React flux architecture

浪子不回头ぞ 提交于 2019-11-29 11:45:35
问题 We have a react application with Flux architecture, I am searching any good library for sending http request like angular's $http, $resources. 回答1: You don't need something specific for React or Flux, you can use a regular CommonJS module. There are several you can use, my favourites are: Superagent: small, easy to use and easily extensible via plugins Axios: really nice implementation of the Promise API and Client side support for protecting against XSRF (plus supports IE8) Fetch: built by

redux和flux思想: 从代码层面而言,flux无非就是一个常见的event dispatcher,其目的是要将以往MVC中各个View组件内的controller代码片断提取出来放到更加恰当的地方进行集中化管理,并从开发体验上实现了舒适清爽、容易驾驭的“单向流”模式。 但为了区分于以往的MVC模式,并向facebook的贡献表达敬意,后面我们将把这种优化后的 Model-View-Controller 开发模式在React背景下正式称为Flux模式 来源: https://www.cnblogs.com/twizcl/p/11515552.html

Spring WebClient vs. RestTemplate

∥☆過路亽.° 提交于 2019-11-29 07:01:39
1. 简介 本教程中,我们将对比 Spring 的两种 Web 客户端实现 —— RestTemplate 和 Spring 5 中全新的 Reactive 替代方案 WebClient 。 2. 阻塞式 vs 非阻塞式客户端 Web 应用中,对其他服务进行 HTTP 调用是一个很常见的需求。因此,我们需要一个 Web 客户端工具。 2.1. RestTemplate 阻塞式客户端 很长一段时间以来,Spring 一直提供 RestTemplate 作为 Web 客户端抽象。在底层, RestTemplate 使用了基于每个请求对应一个线程模型(thread-per-request)的 Java Servlet API。 这意味着,直到 Web 客户端收到响应之前,线程都将一直被阻塞下去。而阻塞代码带来的问题则是,每个线程都消耗了一定的内存和 CPU 周期。 让我们考虑下有很多传入请求,它们正在等待产生结果所需的一些慢服务。 等待结果的请求迟早都会堆积起来。**因此,程序将创建很多线程,这些线程将耗尽线程池或占用所有可用内存。**由于频繁的 CPU 上下文(线程)切换,我们还会遇到性能下降的问题。 2.2. WebClient 非阻塞式客户端 另一方面, WebClient 使用 Spring Reactive Framework 所提供的异步非阻塞解决方案。 当

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
