For every application Yury Dymov works on, he needs to decide how to manage the data. The problem can be broken down into the following three subproblems: Fetch data from the back end, store it somewhere locally in the front-end application, retrieve the data from the local store and format it as required by the particular view or screen. In this article, Yury sums up his experience with consuming data from JSON, the JSON API and GraphQL back ends, and it gives practical recommendations on how to manage front-end application data.

Fuse is not only used to describe the UI and layout; you can also use it to add effects and animation. In this article, Wern Ancheta will show you what Fuse is all about. He’ll show you how it works and how it compares to other platforms such as React Native and NativeScript. In the second half of the article, you will create your first Fuse app. Specifically, you will create a weather app that shows the weather based on the user’s current location. Towards the end of the article, you will consolidate your learning by looking at the advantages and disadvantages of using Fuse for your next mobile app project.

The key reason for Eric Rozell’s investigation of ChakraCore was to support the React Native framework on the Universal Windows Platform, which is a framework for declaring applications using JavaScript and the React programming model. Embedding ChakraCore in a C# application is quite easy and in this article, Eric Rozell will show you how.

Traditionally, scaling was mostly relevant for server-side systems. As more and more users would use your application, you needed to make sure that you could add more servers to your cluster, that your database could be split across multiple servers, and so on. Due to rich web applications, scaling has become an important topic on the frontend. The frontend of a complex app needs to be able to handle a large number of users, developers and parts. In this article, Max Stoiber shares everything you need to now about React Boilerplate to get started.

Getting an app just right, getting it to work across all possible devices, with different OS versions, display resolutions, chipsets and other hardware characteristics, and making the user experience smooth across all possible configurations, is a challenging task. In this article, Ville-Veikko Helppi will look at what’s available for testing React Native apps. He’ll explain some key features of React Native, before looking at how to implement these tests, and then he will categorize testing methods and frameworks on three levels, providing examples for each.

In this article, Filip Bartos will share his notes about installing and configuring a critical-path performance optimization using Express and Handlebars for an isomorphic React website. This website was developed using React, running on an Express server, and it was going well, but Filip still wasn’t satisfied with a load-blocking CSS bundle. So, he started to think about options for how to implement the critical-path technique on an Express server. Throughout this article, Filip will be using Node.js and Express. Familiarity with them will help you understand the examples.

Redux is a predictable state container for JavaScript apps. It’s an application data-flow architecture, rather than a traditional library or a framework like Underscore.js and AngularJS. It is used mostly for application state management. To summarize it, Redux maintains the state of an entire application in a single immutable state tree (object), which can’t be changed directly. When something changes, a new object is created (using actions and reducers). Today, Alex Bachuk will go over the core concepts in detail.

In this part of the tutorial Nash Vail will start by replacing the photographer’s name with the actual wallpaper image along with proper credits. During this process you’ll learn how to link a library in Xcode, as well as more on general styling and positioning of UI elements. You will learn how to save pictures to the Camera Roll and also how to run your app on a physical device. To apply all your newly learned React Native skills there is a challenge waiting for you at the end. Just like the first part, this article has five sections. Completing each section takes us a step closer to finishing our app.

These frameworks and the whole idea of building mobile apps with JavaScript never appealed to me, though. I always thought, why not just learn Swift/Objective-C or Java and build real apps? That definitely requires a significant amount of learning, but isn’t that what we developers do and should be good at? Quickly learn new languages and frameworks? What’s the point, then? For me, the advantages never outweighed the doubts.
