flux

I've been learning React and Flux over the past few months, and one thing I've not yet dealt with is displaying error messages to users. Specifically, error messages that occur as a result of an ajax http request within a flux action creator method. A simple example is user sign in - if the sign in ajax request fails due to a bad password, the server responds with the failure. At that moment, within my flux action creator method, my only option is to dispatch an action containing the error information, right? I can dispatch the error information and keep that error in a store. I'm not sure

It passes in two vectors with three values each, and should pass out one vector with three values as well. I call the function like this: Fr = Flux ( W (:, i ), W (:, i + 1 )) What I have realized through messing around with the code, trying pure functions, and modules, and researching the error statement (that I will include at the bottom), is that fortran is reading my function Flux, and thinks that the input vectors are an attempt to call an entry from the array. That is my best guess as to

I want to make my App 1 publish Server Sent event through Flux and my App 2 listen on it continuously. I want Flux publish on-demand (e.g. when something happens). All the example I found is to use Flux.interval to periodically publish event, and there seems no way to append/modify the content in Flux once it is created. How can I achieve my goal? Or I am totally wrong conceptually. 回答1: Publish "dynamically" using FluxProcessor and FluxSink One of the techniques to supply data

原文： http://blog.51cto.com/liukang/2090191 Project Reactor与Spring是兄弟项目，侧重于Server端的响应式编程，主要artifact是reactor-core，这是一个基于Java 8的实现了响应式流规范（Reactive Streams specification）的响应式库。 1.Flux与Mono Reactor中发布者（Publisher）由Flux和Mono两个类定义，它们都提供了丰富的操作符。一个Flux对象代表一个包含0~N个元素的响应式序列，而一个Mono对象代表一个包含0/1个元素的结果。 即然是“数据流”的发布者，Flux和Mono都可以发现三种“数据信号”：元素值、错误信号、完成信号，错误信号和完成信号都是终止信号，完成信号用于告知下游订阅者该数据流正常结束，错误信号终止数据流的同时将错误传递给下游订阅者。 Flux.just(1, 2, 3, 4, 5, 6); Mono.just(1); Flux和Mono提供了多种创建数据流的方法，just就是一种比较直接的声明数据流的方式，其参数就是数据元素。 对于上面的Flux，还可以通过如下方式声明： Integer[] array = new Integer[]{1,2,3,4,5,6}; Flux.fromArray(array); List

前面的话 　　Redux是Flux思想的另一种实现方式。Flux是和React同时面世的。React用来替代jQuery，Flux用来替换Backbone.js等MVC框架。在MVC的世界里，React相当于V(view)的部分，只涉及页面的渲染。一旦涉及应用的数据管理部分，还是交给Model和Controller。不过，Flux并不是一个MVC框架，它用一种新的思路来管理数据。本文将详细介绍Redux的内容 MVC 　　MVC是业界广泛接受的一种前端应用框架类型，这种框架把应用分为三个部分： 　　Model(模型)负责管理数据，大部分业务逻辑应该放在Model中 　　View(视图)负责渲染用户页面，应该避免在View中涉及业务逻辑 　　Controller(控制器)负责接受用户输入，根据用户输入调用相应的Model部分逻辑，把产生的数据结果交给View部分，让View渲染出必要的输出 　　MVC框架提出的数据流很理想，用户请求先到达Controller，由Controller调用Model获得数据，然后把数据交给View。但是，在实际框架实现中，总是允许View和Model直接通信 　　然而，在MVC中让View和Model直接对话就是灾难 Flux 　　Facebook用Flux框架来替代原有的MVC框架，这种框架包含四个部分： 　　Dispatcher负责动作分发

I've been working with optimistic updates in a React+Flux application and saw two things: What happens if a user attempts to close the window when exists some uncompleted actions. For example in Facebook, a message appears in the wall even if wasn't really persisted (this is what optimistic updates does, a more responsive application for the user). But, if a user post in the wall and immediately close the application (on logout or window close), the post could fail and he would not be alerted. I don't like the idea of Stores managing his own entities (for example messages) and the situation of

From the discussion here it seems that the state of Redux reducers should be persisted in a database. How does something like user authentication works in this instance? Wouldn't a new state object be created to replace the previous state in the database for every user (and their application state) created and edited? Would using all of this data on the front end and constantly updating the state in the database be performant? Edit: I've created an example Redux auth project that also happens to exemplify universal Redux, and realtime updating with Redux, Socket.io and RethinkDB. Alexander

I'm a bit stuck thinking on how to implement a reducer where its entities can have children of the same type. Let's take reddit comments as an example: each comment can have child comments that can have comments themselves etc. For simplification reason, a comment is a record of type {id, pageId, value, children} , with pageId being the reddit page. How would one model the reducer around that? I was thinking of having the reducer be a map -> id of the comments where you can filter by page using the pageId . The issue is that for example when we want to add a comment to a nested one: we need to
