Since the React hooks API was introduced, a lot of questions have risen about whether or not React hooks will replace Redux. In my view, there is little overlap between hooks and Redux. Hooks didn’t…
Created by Jay Phelps and myself for use on our projects at Netflix, redux-observable is middleware for redux that is inspired by redux-thunk. redux-observable allows developers to dispatch a…
In this article, we’ll compare two options for handling async logic in Redux: redux-thunk and redux-observable. Redux-saga is another option that shares a lot of similarities with redux-observable, but it’s not included in this article.
It has come time to read the liner notes and write some conclusions. When we started writing this blog series, we knew that JavaScript/web application frameworks were not easy to summarize.
When React came out I was really amazed with his easiness of use and learning curve. At starting point of learning React I did not know that React is just a library and not fully fledged framework. I…
Polymer-redux makes using Redux with Polymer as easy as pie (learn in this post why and how). Unfortunately, the library doesn’t allow to bind Polymer properties to Redux selectors. This post discusses approaches to simulate Redux selectors in polymer-redux.
The new context API that comes with React 16.3 is pretty neat. It was built in the render props style trending over these last months. Let’s explore it: This talk from the excellent Jing Chen has…
People often choose Redux before they need it. “What if our app doesn’t scale without it?” Later, developers frown at the indirection Redux introduced to their code. “Why do I have to touch three…
We will be building a user authentication in a single page application with Node, React, Redux and Koa combined with Passport. We will implement local authentication, where users can log in using an email and passport, and authentication with Facebook, which can be used with other social networks and OAuth providers.
Tim Griesser As JavaScript applications increase in complexity, consistent patterns for managing state becomes considerably more important, and difficult to ...
Jay Phelps (@_jayphelps ) talks about why Netflix loves reactive programming with Rx. In this talk he shares the basics of RxJS 5 Observables and how they ca...
I found middlewares both easy to understand and a useful addition to my Redux toolbox. And I think after reading the source code for the following 3 popular middlewares you'll feel that way too.
If you have built Node.js apps using frameworks like Express.js, you are probably aware of functions called “middlewares” and how they work. Redux brings that same concept to the front-end…
In this comprehensive tutorial, Dan Abramov - the creator of Redux - will teach you how to manage state in your React application with Redux. State management is absolutely critical in providing users with a well-crafted experience with minimal bugs. It's also one of the hardest aspects of a modern front-end application to get right. Redux provides a solid, stable and mature solution to managing state in your React application. Through a handful of small, useful patterns, Redux can transform your application from a total mess of confusing and scattered state, into a delightfully organized, easy to understand modern JavaScript powerhouse. The principles of Redux aren't new, but they are packaged and presented for you in an easy to use library that not only elevates your applications, but also improves your general understanding of building JavaScript UIs. In this course, Dan Abramov will show you the fundamentals of Redux, so that you can start using it to simplify your applications. There are some amazing community notes on this course here on Github. Once you are finished with this course be sure to check out part 2: building-react-applications-with-idiomatic-redux
Modern day javascript environments have many ways of dealing with state. One can use closures or classes to have some shared state, but sometimes a more elaborate state management library is needed…
I’m an avid user of Redux-Observable, and while it masks a lot of the difficulties in using RxJS, you still need a deeper understanding of RxJS to handle really complex use cases. Using WebSockets…
Web Components are an amazing way to componentized web applications in small, reusable pieces. Coding with Polymer, even reusability stops feeling like an afterthought but something one naturally…
There’s no idiomatic way to structure Redux applications yet. And I believe there’s no The Only True Project Structure but I’ll describe what works for me. I started from grouping by type. It works…
I was speaking to an acquaintance one day (we’ll call him John). John and his colleague started making a messaging application, in which they developed the front end using React and Redux. They were…
Welcome to Part 12 of this comprehensive review and summary of Cory House's Pluralsight course Building Applications with React and Redux in ES6. Cory is a Microsoft MVP in C#, founder of OutlierDeveloper.com, avid tech reader, and speaker. He believes in clean code, pragmatic development, and responsive native UIs. Also in this series: Part 1 -…
Redux-Observable is a middleware for Redux which handles cancellation and many other asynchronous side effects by using reactive programming. … RxJS and Most.js are two libraries for reactive programming with which you can handle streams of actions in different ways. … In the following examples, Most.js will be used.
Redux is a predictable state container for JavaScript apps. (Not to be confused with a WordPress framework – Redux Framework.) It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test.
To me, it makes more sense for these pieces to be bundled together in an isolated module that is self contained, and can even be packaged easily into a library.
When I started using React, there was no Redux. There was only the Flux architecture, and about a dozen competing implementations of it. Now there are two clear winners for data management in React…
The Redux Observable RxJS: Going Epic tutorial will show you how to reactive programming in Redux. The middleware can be used in Redux applications. The example shows it in a React JS app...
Components can be tested with snapshot testing. Tools like Jest (often combined with Enzyme) that offer this functionality take a ‘snapshot’ of what your component renders — everything from divs…
