React native software was released by Facebook, back in 2015. And it has been a revolutionary innovation in the field of mobile app development. The list of the list of its popularity is long, including the fact that it is cost-effective, time saving and it is an open-source framework, so it can be used by anyone. According to a survey, React Native is the most used framework by the developer in 2021. Another statistic states that about 42% of the developer community uses React Native for mobile app development.

Since the increased usage and demands of app developers in New York, the requirement of the suitable tech stack is necessary to ensure the applications have a correct data base for React Native. In this article, we will share some necessary consideration before choosing a Database for React Native app development, and what are some of the best databases.

Factors to consider while choosing the database for React Native

Handling of memory

Apps may crash more frequently if data is not handled appropriately. Although most databases clear their cache on a regular basis, this guarantees that a program has enough RAM to run effectively.

Usability factor

The react native database that you decide to work with must have the feature of easy merging. This will assist you in improving the development process and making the job of developers easier.

Data conflict management

You may have additional data conflicts as you add more cooperation-related features to the program. Investigate the database documents to see how they handle synchronization and conflicts, or look into the trade-offs that are made and how they affect the app.

Top database for react Native app development


It is an open-source, object oriented database that works 10 times faster as compared to a relational database. It also supports complexed data for applications that are real-time and offline. It has its own search engine and doesn't require any key-value storage or object-related mapping. The objects in the Realm database can be accessed from several sources.

Some of the benefits of Realm includes:

• To save user engagement, its synchronization runs in the background.
• It has a fantastic set of APIs.
• For each mobile platform, it employs different encryption standards.
• With Redux offline, Realm may be used offline.


This google owned database has NoSQL. If your application is more inclined towards the offline data synch and updating, then firebase might be the best choice for you. Firebase is a great way to handle MVC-based React Native apps with a lot of data. Furthermore, Firebase has performance tracking tools that might assist you in determining the cause of a bug in your application.


• It is easily combine with any application.
• It aids in data synchronization across multiple platforms.


The initial intention for creating SQLite was to give the users a capacity for local storage database in mobile applications. The word ‘Lite’ in the name suggests that this database is light-weighted and requires minimal setup. It performs the most SQL policies and includes additional features to make data management easier.

SQLite benefits:

• It is a time saver in terms of its cross platform database file feature
• An app's storage can be used to provide offline persistence.
• It is ACID compliant, which means it can run almost any SQL standard.


As a developer, while you search for the best local database to use for react native app development, you must list down your requirements, without compromising any of them. Your applications success is dependent on the database you choose to work with, so make a wise decision.
