“What?!”, you say. “GraphQL is a server side query language. Redux is a client-side state management library. How could one replace the other?” Good question.graphql redux

This blog is about when you should start thinking about using Redux, the problems it solved for us and the benefits we found. It is based on what we learnt from scaling up our React app.react redux

One common trend I find among most Redux developers is a hatred towards setState(). A lot of us (yes, I’ve fallen into this trap many times before) flinch at the sight of setState() and try to keep all the data in our Redux store. But, as the complexity of your application grows, this poses several challenges.

In this post, I’ll walk you through various strategies to model your state, and dive into when each of them can be used.react redux

Instead of using classes and local state, Deku just uses functions and pushes the responsibility of all state management and side-effects onto tools like Redux. It also aims to support only modern browsers to keep things simple.

It can be used in place of libraries like React and works well with Redux and other libraries in the React ecosystem.

Deku consists of 5 modules packaged together for convenience:

• element: Create virtual elements.
• diff: Compute the difference between two virtual elements. You can use this if you're creating a custom renderer.
• dom: Create DOM elements from virtual elements and update them using the result of a diff. You'll only use this directly if you're building your own app creator.
• string: Render a HTML string from virtual elements.
• createApp: Kickstart an app for the browser.

react redux

An extremely fast React-like JavaScript library for building modern user interfaces.

• Tiny Size: Inferno is much smaller in size, 9kb vs 45kb gzip. This means inferno is faster to transfer over the network and much faster to parse.
• React Compatible: React-like API, concepts and component lifecycle events. Switch over easily with inferno-compat.
• Insane Performance: One of the fastest front-end frameworks for rendering UI in the DOM, making 60 FPS on mobile possible.
• One-way Architecture: Component driven + One-way data flow architecture. Bindings also supplied for Redux, MobX and Cerebral.
• Isomorphic rendering on both client and server, along with fast-booting from server-side renders.
• Modular: Highly modular with very little opinion of how things should be done, removing bloat and unecessary overhead.

Managing state in modern web applications is hard. As applications grows in complexity, keeping track of state changes and mapping those changes back to your UI becomes increasingly difficult.

One way data flow makes managing state more approachable and lightens the cognitive load required to follow the flow of data through your application. Using Redux takes this idea to the next level and moves the state and the state changes and centralizes them in a global store, managed with pure reducer functions.

In this course you will learn how to build a production quality React application using Redux. We will build up from using redux by itself, so we can understand the core API and how that interacts with a React application, then we’ll move on to introduce react-redux to abstract away some of the underlying details and clean up our code. We’ll use middleware and a mocked API server to understand how asynchronous code fits into the Redux model and we’ll even deploy our finished work so we can see it running live in the cloud.map react redux

Redux is an excellent tool for managing the “state” of an application. The unidirectional flow of data and the focus on immutable state makes reasoning about changes to the state simple. Each update to our state is caused by a dispatched action, which causes our reducer function to return a new state with the desired changes. Many of the user interfaces we create with Redux at AppNexus deal with large amounts of data and very complex user interactions as our customers manage their advertisements or publishing inventory on our platform. Over the course of developing these interfaces, we have arrived at some helpful rules and tips to keep Redux manageable. The following points of discussion should help anyone working with Redux on large, data intensive applications:redux

If, like myself, you’ve ever created a website using the “standard” tools of plain old HTML or templates, preprocessed CSS, and JavaScript, then you may also have shared the same delight I did when React came along and offered a way to easily break a website or app into manageable, reusable chunks.

This also came at a time when JavaScript was maturing immensely, going from what some considered a “toy language” to one of the most popular languages out there today. After promises came on the scene we could forget about writing sideways pyramids and getting ourselves into callback hell. Then along came async/await, and now most of us try to avoid those “messy and confusing” promise chains wherever possible. We are spoiled, literally, for choice.

Then along came Flux, after that Redux. State management just got a whole lot easier, and although you might not always need it, Redux is often the go-to state management tool for a lot of developers. That little extra initial setup often goes a long way and saves us major headaches further down the line.

s the language evolves so fast it’s hard to keep track of all the new features, so this article is about my personal opinion on how to make the best use of them to improve your components without sacrificing anything whatsoever.

I should point out here that in all my examples I’ll be using React Native, but the principles are exactly the same in React… So let’s get into it!react redux javascript

If you’re using Redux in your React app you’re likely using react-redux to connect your components to your state. The connect method is a tricky sum bitch— although it has a very simple API there’s a lot of magic happening under the hood. It’s very easy, especially when first learning Redux, to just start connecting things without much thought on what’s actually happening. One of the easiest snafus to make is to connect your component at the top of the render tree.

What the hell does that mean exactly? I’m glad you asked — the following diagram demonstrates this scenario. In this example the component is connected at the top of the render tree.react redux

At its core, React is just JavaScript. It doesn't need a build system or fancy syntax. And with just two functions, it lets you create something amazing...

So you’ve heard all the fuss about React – apparently it’s the best thing since Visual Basic. But you’ve spent a couple hours investigating, only to find so many buzzwords that it just feels overwhelming. NPM and Redux and Babel and react-router and Webpack and all I want is somebody to just tell me how to use React already!

Luckily for you, that’s exactly what this guide will do! Don’t believe me? That’s OK – you will after you’ve built your first React app in only 2 minutes. Without downloading or installing anything. Just by following this exercise…react redux npm

Switching to a declarative approach at Major League Soccer

I’m a firm believer that the best code is no code. More code often leads to more bugs and more time spent maintaining it. At Major League Soccer, we’re a very small team, so we take this principle to heart. We try to optimize where we can, either through maximizing code reuse or lightening our maintenance burden.

In this article, you’ll learn how we offloaded data fetching management to Apollo, which allowed us to delete nearly 5,000 lines of code. Not only is our application a lot slimmer since switching to Apollo, it’s also more declarative since our components only request the data that they need.

What do I mean by declarative and why is that a good thing? Declarative programming focuses on the end goal, while imperative programming focuses on the steps it took to get there. React itself is declarative.graphql react redux
