Every second, every day we are spending our time on various applications, be it health apps, dating apps, social media apps, etc. there is an immense increase in the demand of applications. With so much increase in demand, developers also had their share of struggle to develop for multiple platforms.
This led to innovation of new frameworks and programming languages like React Native, Flutter, Xamarin, and more which supports cross-platform app development. Today React Native is the leader when it comes to developing cross platform applications. Developers prefer it because of its ease of learning.
But, with this, there is also increasing confusion between ReactJS and React Native. It is the most debated question and so finally here is your answer. Let’s start!
In this article I will walk you through the difference between React JS and React Native. If you are someone who is often confused between these two, you are at the right place. Read more, to know everything about ReactJS and React Native.
What is ReactJS?
ReactJS is made of two parts i.e. Components and HTML documents. Components are useful to contain HTML code and what you want to see in the user interface, whereas HTML documents are useful to render all components.
Advantages of ReactJS:
ReactJS has the ability to load the website and applications faster as it uses Document Object Model (DOM). React develops an in-memory data structure cache that computes the resulting differences; it then updates the browser’s displayed DOM seamlessly. The programmer writes the code in a way that the entire page renders whenever there are changes. But, in reality, only the sub-components which you have changed render. This leads to faster loading of pages; faster loading of apps and websites is essential for SEO ranking of your business.
Component based Architecture:
ReactJS came up with the concept of component-based architecture, which focuses on the reusability of components and in-turn helps save time. It uses individual pieces of a large user interface and converts them into an independent, self-sustaining micro-system.
For example: you have made a website using ReactJs and want to make changes in certain sections. So, instead of changing the entire website, you can reuse and redefine particular components, as a result, saving time, and resources. Moreover, you don’t even have to go through the complexity of coding or running into any bugs.
Useful for SEO:
When building a website or an application you need to consider SEO ranking as it is the way of reaching more customers and increasing sales. Being a server side rendering, it is useful to boost the SEO of the webpage/app and attract more organic traffic. When a Google bot visits a server that has rendered content and images, then the indexing, and caching becomes faster. It helps in the SEO of your website. Moreover, if the Google bot directly indexes the content from server-side, the page load time also decreases. As a result, the website loads faster and users will not need to wait for a long time.
Many Developer Tools are Available:
ReactJS has a large number of developers who contribute and develop an ecosystem of tools, component libraries, IDEs, extensions of code editors, web browsers, and more. This provides developers with a wide range of third party tools and extensions which helps them in ReactJS app development. Due to the large support from the community and its open source nature, ReactJS is one of the most popular choices when it comes to developing applications.
Going further, let’s talk about limitations of ReactJS which you need to take care of while developing:
Disadvantages of ReactJS:
Exceeds Cost and Time:
When working in a different framework and using ReactJS, you will need to download the other extra components and libraries to work efficiently. This increases the cost and time of app development.
External Library Support:
Complicated Data Navigation:
Data navigation within ReactJS is complicated and complex because ReactJS does not support parallel data handling like other JS Scripting tools. To navigate between the Divs in ReactJS, developers need to first navigate to the parent node, followed by the topmost parent node, and then to the second hierarchy of the tree node. This can be a difficult and tiring process to navigate between the data.
Bit Difficult to Learn:
If you are new to development and thinking of learning ReactJS, it is a bit difficult compared to React Native. So, new developers need to have patience and not be hard on themselves.
Now, let’s see React Native in detail:
What is React Native?
React Native is a cross platform mobile framework that uses ReactJS for developing applications and websites. It uses native app components which helps developers to build mobile applications which can run cross platform. ReactJS is useful to build components under React Native.
Advantages of React Native:
Platform Specific Code:
When you start with React Native app development, it automatically understands the platform it needs to run on. Thus, it generates the right code for the platform. This is one of the USPs of it and makes the development process simpler.
Easy to Develop Applications:
Hot and Live Reloading:
Hot and Live reloading are the two most talked benefits of React Native. Live Reloading can compile and read the changes made by a coder. It also uses a new file simulator which then automatically reads the app.
Hot Reload uses Hot Module Replacement and was introduced after the first reloading process. Hot Reloading has one advantage, that is, after saving changes in the file, an HMR intermediator comes forward and keeps the updated files in perfect places while the application operates in the background. The main advantage of using Hot Reloading lies in the ability to make changes in the source code even when it does not recompile the application.
When the developer makes the changes in the code they can immediately see the results in real-time. Hence, with the help of Hot Reload, the waiting time for the output decreases.
Ready to Use Libraries:
Component UI libraries exist in React Native which developers can use to make a smooth UI experience. Sharing of UI libraries like Shoutem, Expo, native base, and others can save time and no need to build the components from scratch. As a result, developers can focus on their work, and save time.
Going further, let’s see the limitations of React Native:
Disadvantages of React Native:
Fewer Native Libraries:
If the application has complex and heavy functionalities, the React Native app development process can slow down because it has less native libraries and dependencies on external or third-party libraries. When one needs to carry out complex calculations at the same time, then Swift, Objective-C, and Java are better alternatives.
Improper Abstraction Layer:
Takes Time to Initialize:
Exceeds Cost and Time:
If the developer needs the particular functionality and is not found then they are left with two options.
- Write the native modules in Swift/Objective-C/ Java
- Ask other native app developers to help them write one
In either case, the development process consumes lots of time and resources and makes the process complex.
ReactJS or React Native: Which is Better?
This is a long held debate but one needs to understand that both complement each other. Both of them are important when it comes to React Native app development. Today they are known and accepted widely because of their constantly upgrading ecosystem, flexibility, and support of third-party applications.
When it comes to choosing between either of them, you need to understand that you will need both of them to make your application work. If you are thinking of getting started with app development, you can reach out to us. Our experts will help you at each phase of app development.
