The entire platform of React Native has grown massively in the last few years, with many people flocking to it and trying to understand how it works under the hood and how to use it to create apps that can be used on multiple platforms, such as Android, iOS and web browsers.
The platform has a lot to offer, but there are some things that React Native developers should be aware of and consider before beginning development. In this guide, we’ll take you through seven important considerations that every React Native developer should be aware of.
1) The need for speed
React Native is a JavaScript framework that is used to build native apps. This makes it possible for you to write your app in the language you're most comfortable with, without compromising on features and design. The need for speed comes into play when considering the latency between JavaScript and Java, which can be as low as 100ms. This also makes it possible to use Flux or Redux on a mobile app in order to achieve an unrivaled user experience.
2) Code reusability
React Native has a lot of benefits, but there are also some downsides that you should be aware of. One of the drawbacks is a lack of code reusability between iOS and Android apps. If you're looking to share code between your apps, then you'll have to write a wrapper for your iOS components or use JavaScript Bridge. Another disadvantage is that cross-platform development can be difficult because it requires having an understanding of different platforms and frameworks.
3) Platform fragmentation
The first thing that you'll want to consider is the fragmentation of your app. If you're building an app for iOS and Android, then this won't be a problem for you. However, if you only want to create an app for one platform, then you'll need to make sure that it's compatible with both versions of the operating system. For example, if your app is only going to be developed for Android, then your development company will need to ensure that they're using Google's newest SDKs as well as making sure that they're using the newest version of Android (currently Nougat). This can be difficult because it requires keeping up with the latest updates from Google and Apple on a regular basis.
4) The learning curve
React Native is a framework for building native mobile applications with JavaScript. It's based on the idea of a 'learn once, write anywhere' paradigm, which means it's possible to develop an app that will run on both iOS and Android from a single codebase. The learning curve for React Native is more or less like any other framework out there: you'll have to invest time in understanding the library before you're able to harness its full potential.
This can take anything from days to weeks or even months depending on your previous experience with JavaScript frameworks and libraries. However, if you are determined enough and work through all the available resources (websites, tutorials, videos) then mastering this framework shouldn't be too difficult.
5) Community support
Community support is important for any developer, especially when you are learning a new framework like React. There are many different resources to ask for help and get advice from other developers, but the most important one is Stack Overflow. For example, there are many questions on Stack Overflow about specific features or how to use certain APIs.
If you find yourself stuck on a problem that doesn’t have a clear answer in the documentation or tutorials, it might be worth posting your question there and waiting for people to reply with their suggestions. The other great thing about Stack Overflow is that not only can you learn from other people’s questions and answers, but you can also contribute by answering questions too!
if you want to convert your ideas into reality then you should hire react native developers.
6) JavaScript fatigue
JavaScript fatigue is a term used to refer to the feelings of frustration and confusion that come when you try to keep up with all of the new JavaScript libraries, frameworks, and services. Sometimes it feels like there are too many options out there, or that you are choosing the wrong one for your project. There is no perfect solution for solving this problem but by following these steps, you can at least reduce the amount of stress caused by JavaScript fatigue:
1) Find a library that does what you need it to do
2) Spend time learning about its features so that you can use them most effectively
3) Avoid using more than two popular libraries in your project.
7) Licensing
Choosing the appropriate license for your code is an important decision. There are three main types of licenses: permissive, copyleft, and proprietary. Permissive licenses (sometimes called viral licenses) allow anyone to use your code in any way they want with no restrictions.
Copyleft licenses require that all modifications and additions to the original program be available as open source under the same terms as the original software license. Proprietary licenses only allow you to use the program but not modify or redistribute it in any way.
