What is React Native?

A JavaScript framework, React Native, facilitates writing natively rendering applications for mobile devices, both Android and iOS. The framework draws from React, the JavaScript library Facebook uses for developing user interfaces (UI).

However, React Native is aimed at mobile platforms rather than the browser. It allows a web developer to write truly “native” mobile applications using an already existing and popular JavaScript library. Additionally, it helps write simultaneously for multiple platforms as the written code can be shared between platforms.

React Native apps are written with a combination of XML-like markup called JSX and JavaScript. The application renders using components of a real mobile user interface instead of web views, so it feels similar to any mobile application. This is achieved by React Native rendering APIs in Java for Android and Objective-C for iOS.

Since it also brings out JavaScript for platform APIs, the applications built can access its features such as the geo-location or phone camera. Currently available for Android and iOS, it can very well expand its horizons and support further platforms in the future.

Why use React Native to build a mobile app?

React Native is ideal for developing stable and inexpensive cross-platform applications. Unlike many other frameworks, it uses a native API component to look and feel like a native app for that platform.

Here are a few reasons why React Native is perfect for creating cross-platform apps.

FlexibilityVery High
Building BlocksPre-loaded elements to simplify coding
StabilityThe framework is running for a long time and it’s extremely stable vs. the other option
CommunityLarge community of developers supporting the platform

Below, some more granular information about the advantages of React-Native.

Saves you time and saves you money

Its cost-effectiveness makes Real Native a great choice. The code used to create an app can, for the most part, can be used on other platforms. It’s an amazing choice to create cross platform iOS/Android app in short time and reduce engineering working hours.

Even in terms of quality, the costs are dramatically reduced by highlighting errors instantly. Because it uses common codes, the time to debug is also decreased as they only need to be fixed once.

Technology Standardization

Using RN, there is no need to have multiple development teams for iOS and Android. The framework shares an impressive 90% of the code among Android and iOS. Real Native can be used by a single team of developers who excel in a certain range of technologies instead of several teams. This ensures a more reliable process and avoids chaos.

Ready to Use Building Blocks

The pre-built components within Real Native enable speedy development. For example, a developer has already finished coding for a few functions, which you need for your app; you can use the codes completely free.

Hot Reload

Perhaps the framework’s most dominant feature is that a developer can refresh the app while in the development phase. This also saves time by automatically refreshing the app with the changing codes. Also, the developer can keep track of every change with live-tracking.

Plugins, plugins, and more plugins

There is a wide variety of well-tested plugins for React Native. Many developers using other frameworks face problems due to the inability to use third-party plugins as they aren’t available to the same extent, but React Native lets you add plugins. Being a flexible platform, it comes with realistic interfaces supported by several options to customize.

Declarative coding style and modular architecture

Declarative coding makes the process of developing apps using React Native flexible and smooth. Modular programming lets the developer easily distinguish any program’s functionalities into separate modules. The ability to check other projects simultaneously allows quick update generation.

Simple User Interface

React Native has a very simple and easy to use UX. Developing an application is difficult, especially if a systematic approach isn’t followed. With Real Native, building mobile apps is easier because it regulates every step’s procedure and has a reduced loading time.

Variables to consider when choosing a React Native database

Choosing the right database is hard and the options available are vast. So, evaluating the right variables are essential to determine the best option. The three most important variable when evaluating a database are:

  • Relational vs. Non-Relational (or SQL vs. NoSQL)
  • Open-Source vs. Proprietary
  • Scalability

Now, let’s dig deeper into these variables.


If you are confused between opting for an SQL and NoSQL database, consider these points:

  • Unlike NoSQL databases, which are also known as non-relational databases, SQL databases are relational.
  • SQL databases consist of a predefined schema and use structured query language; on the other hand, NoSQL databases handle unstructured data with its dynamic schemas.
  • While SQL databases are scaled vertically, NoSQL databases are scaled horizontally.
  • In contrast to table-based SQL databases, NoSQL databases may be graph, key-value, document, or wide-column stores.
  • NoSQL databases are better for documents, JSON, and other unstructured data, but SQL are perfect for multi-row transactions.

Proprietary vs. Open-Source

Proprietary software refers to guarded commercial software, which isn’t available elsewhere. Open-source, on the other hand, are those whose source code can be found for free over the Internet. Here are some points to differentiate between the two.

Ownership of data:Proprietary tools may allow you to extract data from them because it hardly brings them any kind of profit. However, you are not guaranteed to get the data. It quite simply means that you won’t have primary access to the data you created.Open source tools enable priority access to your work. You don’t need permissions to get the data you need. You also have full control over how you exchange the data when exporting it from one app to another.
Improving and adaptingIn the case of proprietary software, you either adjust yourself according to the provided guidelines or contribute freely to a different market. So, it means that the software and its usage is completely yours when using open-source.Whether intentionally or not, you may end up enhancing the open-source tool you are using. It depends on you downloading the source and adjusting the app according to your comfort. How you use it can create a meta-tool for you without modifying the software, in ways the author of the project or other users may have never thought.
Choosing to not upgradeProprietary services push a lot of upgrades and have the right to alter its product, which you must follow. Suppose you’re using a photo editing software which has been changed; you can either adapt to the changes or stop using the software. Proprietary services maintain all the rights to suddenly add or remove features without warning.Changes are common in open source too, and it can be frustrating enough for you to seek an alternative, but it differs from proprietary by allowing you to hold the unaltered code base. Along with you, plenty of others do too, which opens up the doors to branching the project. There are numerous examples of this.
When using a proprietary tool to share documents or a design, if you need to work with another person, they will have to sign up for the same service because most proprietary services generally ask for accounts.It is the same with some open-source items too but it is rare for them to collect and sell your data like other proprietary vendors.
IndependenceNot reallyNo other tool offers as much freedom as open-source; not just to you but also those you want to collaborate with. Even though few use the same copy or assets of the tool you use, a difference always exists when sharing data. This is balanced by the fact that keeping your projects and data open allows you and others to contribute.


Scalability can be described as a system’s capability to handle a constantly increasing amount of work. It also refers to the ability to perform more work in the same amount of time when its processing power is tested by accommodating growth. You can call a system scalable if it can bear a growing workload and throughput when extra elements are being added.

Firstly, check how you can scale the databases and inspect each process’s pros and cons. There are two primary means to scale database systems – horizontal and vertical scaling.

Sometimes called scaling out, horizontal scaling refers to including hardware to an existing system, which also means adding new servers to a system.

Vertical scaling is known as scaling up. It is the process of including resources like more powerful CPUs or memory to an existing server.
