When it comes to cross platform mobile app development, React Native dominates and outperforms all other leading platforms. It is even more astounding how, despite its maturity, React Native has managed to win the hearts of millions of developers with its user-friendliness and excellent performance feature.

However, choosing the best React Native local Database for your application can be very time-consuming. 

To choose among the wide range of databases that are readily available on the market, 

asses their functional diversity, check the application requirements by a developer, and verify multiple aspects such as:

• security, 
• real-time synchronization, 
• read/write operations speed

After all, the database will determine how well your application performs. Therefore, making the right choice becomes crucial.

In a nutshell, there are a lot of limitations that seasoned React Native app developers feel when selecting databases. So, to simplify this situation, this blog provides you with the list of the top local databases for React Native Applications. Let’s have a look!

Best Database to use in React Native App Development

1. WatermelonDB

• Another React Native database is WatermelonDB. It provides a new way of dealing with the data of users in mobile and web apps built on React.

According to Github, it is optimized for developing complex apps that focus on real-world performance.

WatermelonDB has the ability to scale thousands of records in less than a minute. While doing so, your apps might get slow during the launch process, particularly on Android devices. Hence, to cope up with that, it handles data persistence with slow-end devices by being lazy. As a result, you can’t load any query if it was not requested in the first place. It also supports highly cached as well as multithreaded async functions.

1. Realm

The Realm was introduced in 2004 to streamline the creation of mobile applications and aid developers. It’s a cross-platform, open-source, object-oriented database that’s commonly used for mobile and website development services.

Realm object server and Realm database are the two parts of this Platform. These components work together to synchronize data automatically, enabling a variety of use cases, from offline applications to intricate backend integrations.

It’s not even necessary to use object-related mapping or key-value stores since it has its own search engine.

Additionally, it provides database solutions for the following programming languages: JavaScript, Swift, Kotlin, Obj-C, and.NET.

1. Firebase

Firebase is a NoSQL database owned by Google. It is best suited for applications that require offline data updating and synchronization. Firebase can effectively manage MVC-based React Native apps with large data requirements.

Furthermore, This database can assist you in monitoring the performance and crashes of your app, as well as errors, battery consumption, network requests, and other metrics. In this way you can have complete control over data from the Google server at any time.

Firebase’s assessment procedure includes ISO 27001, SOC1, SOC2, and SOC3. This database is free to use up to 1GB, after which you must pay $25 to store nearly 2.5GB of data.

1. PouchDB

This is a free and open-source JavaScript database, which saves data in JSON format and allows all CRUD (Create, Read, Update, Delete) functions to be queried and mutated through a simple JS API.

PouchDB allows apps to store data locally even when they are offline and then sync it with compatible servers and CouchDB when they are back online, keeping all user data synchronized regardless of where they log in next. PouchDB, as a dependency, is small.

Moreover, it simplifies data security for a React Native app. The way it does that is by including an authentication system for React Native and features such as password storage in the harsh form with the PBKDF2 crypto algorithm to protect encrypted keys from degraded attacks.

1. SQLite

Are you looking for a solid and well-designed database for your React Native app development? Then SQLite database is the one. It is an RDMS (relational database management system) that addresses the storage needs of the mobile app.

Since the database only needs a minimal amount of setup, database administration, and resources, it is referred to as being “lightweight” by the term SQLite.

Additionally, the SQLite Encryption Extension (SEE) is an add-on to the public domain version of SQLite that allows an application to read and write encrypted database files.  

1. Async

AsyncStorage is a simple, asynchronous, and unencrypted module that allows you to store data offline in React Native apps. A key-value storage system is used for data persistence. This module can be useful in a variety of situations.

For anything more than light usage, it is recommended that you use an abstraction on top of AsyncStorage rather than AsyncStorage directly because it operates globally.

On iOS, AsyncStorage is supported by native code that stores smaller values in a serialized dictionary and larger ones in separate files. On Android, AsyncStorage will use either RocksDB or SQLite depending on what is available.

1. BerkeleyDB

Among various React Native databases available, there is another sophisticated database, BerkeleyDB, which provides a number of data-handling options. It is an open-source, high-performing React Native backend that enables developers to handle data in a variety of ways. It provides an API for multiple languages, including iOS and Android.

As already mentioned, it can handle data in a variety of ways, including relationally, as SQLite does, and as byte arrays with multiple data items for a single key.

1. Vasern

Vasern is a new data storage framework for react native app development services that has several advantages over traditional frameworks. The fact that Vasern uses a declarative approach to coding is perhaps the most significant advantage. This makes the Vasern code much easier to read and understand. Vasern also outperforms traditional frameworks in terms of performance thanks to its use of a virtual DOM. 

Finally, Vasern is built to work on all major platforms, including iOS, Android, and Windows Phone. It makes features like document versioning, tagging, and full-text search available to the developers, making it easy for them to manage their documents more effectively.

1. Back4app

This database assists developers in creating APIs that are seamless without the need for coding. It provides the tools required to build a complete cloud-based application backend with known functions and consideration for third-party services.

It is a server-less database for react native apps that allows you to quickly lead relational inquiries and create relational information models. The platform is built on a variety of open-source technologies.

1. Amazon RDS

There are several cloud-based databases available, such as Amazon RDS, which simplify the setup and workflow. It provides scalable capacity at a low cost while automating time-consuming administrative tasks such as provisioning hardware, configuring databases, patching, and performing backups and restores. 

The specific needs for speed, availability, security, and compatibility of your applications can then be developed and maintained with less time and effort.

Final Words

To sum up, selecting the appropriate local database is essential for the success of your React Native mobile application. You can guarantee scalability, security, speed, affordability, and compatibility by picking the best React Native local storage solution.
