As a business owner, you should have the highest quality cross-platform apps to expand your field. Cross-platform applications are affordable projects and also have very little development cycle time. To develop a reliable and successful cross-platform app, it is essential to use the right framework i.e., React Native.

In the tech era, React Native is considered the best framework for cross-platform application development. Whether it is Android or iOS, demand for React Native is increasing as many companies believe in the working of this ecosystem. Both Startups and established companies want to enter the app domain affordably and time-efficiently. As per the 2020 developer survey, the most famous cross-platform mobile framework used by developers worldwide, and 42% of iOS and Android app developers used React Native. 

However, one of the challenging decisions while developing React Native application is choosing the right database for the project. In this blog, we will discuss all the possible options and help you select the best database. We probably understand many modern-day businesses are depending on this framework to ship high performing native applications. So, here is a list of local mobile app databases for react-native. Before deep-diving into it, let’s first start with the React Native introduction. 

What is React Native?

A native version of React.js, React Native is a popular web library developed by Facebook. It is a JavaScript open-source framework used to design native applications for Android, iOS and Universal Windows platform. That’s why it is often considered as ‘React Native the future of hybrid app development’. 

But, React Native allows a web developer to build truly “native” mobile apps using an already existing and popular JavaScript library. At the same time, it helps write for different platforms as the written code can be shared between platforms. These applications are written with a combination of XML-like markup called JSX and JavaScript. The app renders using elements of a real mobile UI instead of web views. Most popular brands are using React Native are shown in figure:

Why Choose React Native app development?

Here are various reasons are shown in figure why choose React Native for startups and established businesses:

why choose react native for mobile app development

As you know, there are different types of local databases for React Native app development; it is difficult to find the right one for your project. So, here are some factors you should consider before discussing the best local databases for React Native app development projects. 

How to choose the right Database for React Native App Development in 2021

Here are some factors to take into consideration in selecting a database for your React Native app:

Factor #1 – The data complexity

The complexity of data is one of the common factors to consider when selecting the right React Native app database. For maximum mobile applications, data is stored in the form of key values or JSON structure. So, it is essential to select the right local database to manage complex data structures and handle complexity easily. 

Factor #2 – Number of Lines of Code

If you take more than 20 lines of code to write a simple CRUD operation, any advanced database should be your last choice. The reason behind this is that an advanced DB not only makes coding complex but also affects database performance and the overall React Native app development cost. In addition, the processing of long code lines would slow down the app greatly. So, it is essential to use a database that comes with high functionality, especially if it lowers your app’s user experience and delays the release speed.

Factor #3 – Synching of the offline data

Make sure you use a simple database for applications with lower complexity and no multiple-user collaboration. React Native apps work better thanks to simple synchronized functionality. These applications can be synced easily with a server in the presence of an internet connection. If your app has a collaboration feature, you need to go with a complicated DB to facilitate seamless integration. Applications like Trello leverage complicated DB to ensure all documents are synchronized on all devices. 

Factor #4 – Handling data conflicts and agreement

The possibility of a data conflict is directly proportional to the collaboration features of your application. Go with a database that shares the conflict handling policies on the repository website. Ensure you read database documents thoroughly to help you understand how databases handle syncing and conflicts. Also, check out how data complication and agreements affect your app. 

Factor #5 – Memory Management

Did you know that a mobile application can dash due to poor memory management? Squeezing is one of the most used memory management processes that deletes the data and documents that are no longer in use. It always ensures that there is always some free memory available. 

Now, let’s begin to talk about the best React Native database in 2021.
