React Native provides an opportunity to build cross-platform apps for both IOS and Android. This creates a thought that you can build one app that will work on both platforms, so you can cut the costs twice. However, there is a lot of misconception around this framework and the first thing you should know — it’s not a perfect choice for all of the apps. Let’s dive into the topic and understand what are strong and weak sides of React Native and is it worth using.Interest in React Native is IncreasingReact Native was developed in 2015 by Facebook and since that time the interest in this framework was rapidly growing:And it’s not a surprise, because when businesses think about building an application they immediately end up on React Native because of its attractive features.Pros of React (...)

What to use, and avoid, if you’d like to “learn once”, and not suck everywhere.The promise of React Native is “learn Once, write everywhere”. Moreover, a large part of the appeal is code reuse and the possibility of leveraging a burgeoning ecosystem to increase our velocity of development and decrease our cost of maintainability. If React Native can’t achieve that, without compromising the user experience, It’s not worth the trouble.Good First ImpressionsDiving into React Native for the first time, I certainly had the sense that this “isn’t your dads hybrid mobile dev experience”, and got tremendously excited considering what we could do, leveraging the teams existing JS knowledge.

When your React application reaches a certain size and scope, attempting to manage state within component instances adds too much complexity, prop drilling, and code smell. Developers inevitably turn to global state management tools, such as MobX or #redux, to solve these problems and make their lives simpler. I strongly endorse Redux and use it in my personal projects, but not all developers share my sentiment.I have worked on quite a few large projects that have demanded a global state powerhouse behind the React UI. No matter application size, team size, or member seniority, the almost universal opinion of these global state management packages has been overwhelmingly negative.The top two complaints? Boilerplate and learning curve. While these packages solve a lot of problems and (...)

Yes, the two app versions that share 65–70% of JavaScript code. The same codebase gives you easier maintenance and fewer bugs to worry about (because the total amount of code is almost twice less). It saves extra days and weeks you that could spend on new functionality.Damn close to native performance.

Managing React modals with singleton component design

(This post was originally posted to my personal blog)Controlling modals of all kinds (informational modals, custom alerts, image lightboxes, …) across an application is a frustrating problem that we all face when developing apps. When the app is simple, it’s sufficient to place a single <Modal /> component and have a state to toggle it on/off. However, things get complicated when you have different places to present the same modal or different kinds of modal to display in your app.There have been a couple of design solutions for this such as using the React Context API (this blog is an example) or manipulating react-navigation’s StackNavigator (as described in this blog post). In this post, I would like to share my own design for this problem using a singleton <Modal /> (...)
