Advantages of React Native
The fact that React Native renders using its host platform’s standard rendering APIs
distinguishes it from most existing methods of cross-platform application develop‐
ment, like Cordova or Ionic.
While this approach can work, it also comes with drawbacks, especially around performance. Additionally, these methods don’t usually have access to the host platform’s set of native UI elements.
When these frameworks do attempt to mimic native UI elements, the results usually feel just a touch off. In addition, reverse-engineering all the fine details of things like animations takes a huge amount of effort, and they can quickly become outdated.
In contrast, React Native actually translates your markup to real, native UI elements,
leveraging existing means of rendering views on whatever platform you’re working
Additionally, React works separately from the main UI thread, so your application can maintain high performance without sacrificing capability.
The update cycle in React Native is the same as in React: when props or state change, React Native re-renders the views. The major difference between React Native and React within the browser is that React Native does this by leveraging the UI libraries of its host platform, rather than using HTML and CSS markup.
For developers familiar with performing on the online with React, this suggests you’ll
write mobile apps with the performance and appearance and feel of a native application,
while using familiar tools.
React Native also represents an improvement over normal mobile development in two other areas: developer experience and cross-platform development potential.
Risks and Drawbacks In React Native
As with anything, using React Native isn’t without its downsides, and whether or
not it is a good fit for your team really depends on your individual situation.
Because React Native introduces another layer to your project, it can make debugging
hairier, especially at the intersection of React and therefore the host platform.
We’ll cover debugging for React Native in additional depth in Debugging and Developer Tools. and check out to deal with a number of the most common issues. Along an equivalent lines, when updates are released for the host platform—say, a new
suite of APIs during a remake of Android—there are going to be a lag before they’re fully
supported in React Native.
The good news is that in the vast majority of cases, you can implement support for missing APIs yourself, which we’ll cover in Modules and Native Code.
Also, if you do hit a roadblock, you won’t be locked in to using React Native—many
companies have successfully implemented hybrid approaches to app development.
Changing the platform you employ to write down your applications may be a wide selection . Still, I think you’ll see that the benefits of React Native outweigh the risks.
