With over 3.2 billion smartphone users in 2019, it makes perfect sense that the mobile app industry is in bloom. The number of mobile internet users is even higher, reaching 4.2 billion. These numbers are still growing at a steady rate and there’s no sign that the tendency is about to reverse.
What are we all doing on our phones? Well, stats say that 90% of mobile time is spent on mobile applications.
With the market being huge, it got quite competitive in the mobile app business. Companies challenge to deliver a better mobile experience to their users no matter what. They can choose from a vast number of mobile app development frameworks, with React Native being one of them.
In this comprehensive React Native guide, we will explore:
- what is React Native
- the famous companies using it,
- when and why you should use it for your project
- what are its alternatives
- and how to start with it
What is React Native
The work on the popular mobile app development framework started during an internal Facebook hackathon in 2013. It was first released to a global audience at the React.js conference at the beginning of 2015 and in March of 2015, it became an open library on GitHub, quickly taking the mobile development world by storm.
Since then, it has become widely embraced by companies and developers over the world. Why? Doubtlessly, because of its ability to develop beautiful UIs and native apps quickly.
Increase in React Native’s popularity since its release in 2015 – Source
React Native has proved tremendously successful, immediately beating interest in classic Android and iOS development and popularizing the concept of cross-platform app development. You may be confused about what a cross-platform app means, so let me explain this shortly.
What is cross-platform mobile development?
Cross-platform mobile development is a cheaper and more convenient alternative to native Android and iOS development. The app is no longer written to run on one specific OS only.
React Native is considered to be one of the best mobile development options. It lets you save time of development and cut costs, basically in half – cross-platform mobile development produces apps that can run both on Android and iOS.
React Native MVP
React Native is also a great idea for building the Minimum Valuable Product (MVP) mostly because of its super-fast and efficient development process, as well as serving both iOS and Android on one database.
As an experienced React Native app development company, we were working on many MVPs, and so we’ve made a video on how to do it step-by-step:
How React Native works?
What are the examples of apps built with React Native (that are not Facebook)?
The list of large companies using RN is impressive and you probably are using their apps daily. Let me use this guide to introduce you to some examples of organizations that decided to implement React Native library in their products.
In 2016 Instagram dev team started exploring the possibilities of React Native. First, they started their adventure with the simple view of Push Notifications. However, as the results turned out great, they continued developing other parts of the app with the framework.
It allowed Instagram makers to deliver features to both Android and iOS versions of the app much, much faster. Now, the amount of shared code is super high – from 85% to 99% of the code is shared between Android and iOS apps.
All of Tesla’s self-driving vehicles and Powerwall come with built-in React Native applications. The app is a crucial part of the user interface, so the Tesla development team needed to go for the best choice for their business. Whether a Tesla owner uses Android or Apple equipment, all features to control his car, such as lights, locks, roof, or a charger, are equally available on both platforms.
Before React Native, Skype native apps suffered from several issues, such as losing the speed of the app while sharing GIFs and other media.
In 2017 they started working on a brand new application that would be written completely in RN. Therefore, with the old app rebuilt, they developed a couple of new features.
What’s more, they decided to also utilize React Native for the Windows desktop app, showing that its possibilities go further than the mobile app development.
Pinterest decided to integrate React Native in the mobile version of the app, starting with the onboarding process – the Topic Picker view. They saw it needed some smoothing as It is the first view user comes upon after signing up. The initial implementation on iOS took the Pinterest team a record-breaking time of 10 days.
The development team at Bloomberg decided to move their entire product to the cross-platform technology. Before, they used to build their apps with native technologies like Java. Their brand new consumer mobile app for both iOS and Android offers users a smooth, interactive experience letting them easily access personalized content across Bloomberg’s Media.
Another thing they loved about React Native is its automated code refreshments which speed up the process of the new feature release. What they claim is that the development took their team only half the time they would spend not using it.
50 more examples of React Native Apps
And that’s not all of it. RN is used by many Fortune 500 companies and startups. Some other names would be Walmart, Wix.com, Airbnb, Soundcloud Pulse, and many others.
In fact, we have gathered more than 50 great React Native Apps examples in one article.
The benefits and risks of using React Native in your project
As we were making this guide, we couldn’t ignore the fact that React Native has its pros and cons (pretty much like any other solution). Although the benefits radically outnumber the potential risks, let’s take a look at the good sides and the bad sides.
React Native pros
FROM A BUSINESS OWNER PERSPECTIVE
Time & Cost-saving
- Cross-platform mobile development
- Cost-effective and time saving
A single development team, reusable codes, and a supported library mean saving time and money. One of the biggest advantages of utilizing React Native in your product for startups and young businesses who especially care about the money factor.
Learn more about how React Native can cust your development costs.
- Live updates
RN solves the eternal iOS development problem – waiting for App Store to approve any app updates. As long as your app has access to the server to check for a new version, you can publish updates to your app whenever you want – much more like in a web application.
- Extended code sharing
With React Native you can share code not only between mobile platforms but also in a web browser. Just imagine, all of your channels are covered by one shared codebase. Isn’t it great?
UX & Performance
- Great user experience
A mobile application built with this framework guarantees a flawless user experience. With an extremely highly responsive User Interface, it feels smooth and appealing, which will delight your users.
- Great performance
As applications are compiled into natively written code, they not only work on both operating systems but also work the same way on both platforms with no performance losses.
For example, the Xbox team switching from Electron to React Native UWP for their new Xbox app beta for Windows 10. The effect was a leaner native experience on Windows, decreased memory usage (by over 50%) causing massive performance enhancements, and a decrease in app installation size – from nearly 300MB to 60MB.
- Stable future
Facebook is considered a truly stable enterprise after the success of its library, and therefore it has stood by its frameworks, supporting and growing it with a consequence. As it is open source, it makes the vast number of developers continuously help to grow it.
FROM A DEVELOPER’S PERSPECTIVE:
- Pre-developed components
As React Native is widely supported by a great community, you can find plenty of pre-made assets to utilize in your project, making the pace to a release much shorter and faster.
- Easy learning curve
Many frameworks require that you learn a big number of rules that you can apply only within that technology. RN does the exact opposite of this, therefore one of its greatest strengths is how readable it is, even at first contact.
- One ecosystem
One of the advantages of cross-platform development is that a developer can build a versatile application with React Native without dealing with the ecosystem and language specifics of each OS.
- Third-party support
React Native is an open-source project, so it comes with an open environment. You can easily integrate with various third-party modules.
- Great developer experience
Chrome developer tools, flexbox for layout, and many other facilitations – RN has a great development environment that will make building apps easy and enjoyable.
React Native cons
FROM A BUSINESS OWNER’S PERSPECTIVE:
- It’s a relatively young technology
As a quite immature technology, RN isn’t flawless – it lacks some custom modules and some need further development. The great majority of custom modules you will need are working properly, in other words, there are chances that your developers will need to build some solution from scratch. The good comfort is that the solutions are continuously added by great developers from all around the world.
- You may still need help from a native developer
The implementation of some more advanced features typical for native apps may still require support from a dedicated Android and iOS developer. This may be an issue for teams with limited project budgets.
FROM A DEVELOPER’S PERSPECTIVE:
As React Native brings another layer to your project, it can also make debugging harder and more problematic.
It can happen that local library coordination inside a React Native app will require plenty of configurations, so you need to consider some extra time for that.
React Native is still a young technology and, as any solution, it doesn’t come without flaws. Yet, in the end, the benefits definitely outnumber the risks.
When you should consider using React Native for your app?
By going further in the guide, we also have to mention the best option where React Native should be used.
Some certain situations clearly call for, at least, considering RN technology. If at least one of the following reasons feels familiar, React Native may be a good solution for you:
- When you want a stable and fast solution that performs just like a native app
- If you want to build an app that will work on various operating systems but don’t really want to support two or more separate development teams
- When your app is all about the User Interface
- When you are currently working on a web app, but consider creating a mobile app someday in the future
