Another long break! Oh, hey! I didn't see you sitting there. You look bored. How about a Redux release to spice things up? Not a huge set of changes to report here. The biggest change, and the reason for the minor bump, is the UMD build is now done via Rollup. One big advantage is more readable code in the bundle. Rollup does "scope hoisting", which is a fancy term for putting every module at the
Sensible promise handling and middleware for redux redux-pack is a library that introduces promise-based middleware that allows async actions based on the lifecycle of a promise to be declarative. Async actions in redux are often done using redux-thunk or other middlewares. The problem with this approach is that it makes it too easy to use dispatch sequentially, and dispatch multiple "actions" as
By Shahzad Aziz Front-end web development is evolving fast; a lot of new tools and libraries are published which challenge best practices everyday. Itâs exciting, but also overwhelming. One of those new tools that can make a developerâs life easier is Redux, a popular open source state container. This past year, our team at Yahoo Search has been using Redux to refresh a legacy tool used for data a
Redux Hero Part 4: Every Hero Needs a Villain (A Fun Introduction to redux-saga.js) When you think about a classic RPG like Dragon Warrior or Final Fantasy, the bulk of the game involves wandering around on a map and getting into fights with monsters. Does the hero encounter a monster on every tile? No. Randomness is the key. But where does randomness fit in a Redux world where everything is suppo
This is a question that we have all struggled with in building applications. It is an important question because it influences the architecture of our code and how well our app will absorb new features and complexity as it naturally grows during its lifetime. TL;DR (Summary)There are many approaches that will work but it is important to understand the tradeoffs to pick the best solution. I discuss
(Korean, Japanese) Redux is a surprisingly simple library for managing application state with a Flux-like architecture. Here at Affirm, we are particularly interested in Reduxâs time-travel capabilities. Our core business is offering transparent consumer loans, so itâs incredibly valuable to be able to replay the entire loan application process from the userâs perspective. Redux is more of a set o
People often choose Redux before they need it. âWhat if our app doesnât scale without it?â Later, developers frown at the indirection Redux introduced to their code. âWhy do I have to touch three files to get a simple feature working?â Why indeed! People blame Redux, React, functional programming, immutability, and many other things for their woes, and I understand them. It is natural to compare R
debugger.html is a modern JavaScript debugger from Mozilla, built as a web application with React and Redux. This project was started early this year in an effort to replace the current debugger within the Firefox Developer Tools. Also, we wanted to make a debugger capable of debugging multiple targets and functioning in a standalone mode. Currently, debugger.html can connect to and debug Firefox,
Redux-observable allows combining RxJS and Redux by introducing Epics. Epics are Observable streams that handle asynchronous logic in response to Redux actions. This avoids callback hell and enables features like cancellation. An Epic takes an action stream, performs asynchronous operations like AJAX calls using RxJS, and dispatches result actions. This keeps Redux synchronous while managing compl
Letâs face it: developing scalable front-end code isnât piece of cake. No matter how well-structured the framework/architecture youâre using is, everything will be converted to ye olde HTML, CSS and (vanilla) JS. Well, the good news is the open-source community already created solid frameworks (like AngularJS and ReactJS) to make your life incredibly easier, so you can work on high-level code and
Recently having used MobX, I'm trying to reason about why I'm really using it, and trying to truly understand the pros/cons vs redux and cycle. For redux, I think that it comes down to the fact that most people do not need the number one thing redux has to offer, extreme predicability and extreme testability, because their apps are not complex enough. Thus, when they're writing a bunch of reducers
