1. Top Local Databases for React Native
App Development
Mobile app development is a landscapethat has been dominated by two major
OS – Android(87%marketshare)and iOS (60%marketshare) in 2021.However,
sincethe riseof startups,organizationshavemoved towardscross-platformapp
development practices.
The two primary reasons behind this move are cost and time. Most startups
believe that why waste your money in developing two separate apps if you can
get both the experience under one app. This trend has given riseto frameworks
like React Native, Ionic, Xamarin, etc.
Out of all these cross-platformapp development frameworks, ReactNative has
been the most utilized and second most utilized framework for 2020 and 2021
respectively, with a market share of 42% and 38%, respectively. However, not
just the framework, the role of the database becomes highly critical. Keeping
this into perspective, we’regoing to provideyouwith a list of top localdatabases
for React Native that one can utilize to build their business app through React
Native. So, let’s start the show right now.!
1. Berkeley DB
Berkeley DB is a high-performance embedded database used by many React
Native developers around the world. It stores data in key/value pairs and is
written in the C programming language. With simple API calls, Berkeley DB
conducts data management and accessibility functions. Itoffers API for multiple
platforms that include iOS as well as Android.

2. Advantages:
 Very simple to use and understand.
 Supports concurrent access by multiple users.
 Provides industrial-level transaction support.
 Scalable solution for large enterprises.
2. WatermelonDB
WatermelonDB is one of the most innovative ways to handle user data in React
Native applications. If you’relooking to build a complexapplication that focuses
on real-world issues, then WatermelonDB could be your best bet. When it
comes to scaling, WatermelonDB is the best in the business. Lastly, it can also
handle high cached and multi threaded asynchronous functions.
Advantages:
 Lazy loading strategies for data persistence.
 Offline first system and simple data plugging.
 Helps in building apps on top of SQLite.
 Automatic rendering of UI based on database changes.
3. Firebase
Owned by Google, Firebase is one of the NoSQL databases that many React
Native developers are using nowadays. When it comes to offline data
management and data synchronization, Firebaseis your bestbet. Also, if you’re
dealing with an MVC architecture pattern, you can utilize Firebaseas your core
database. It also provides you with a performance tracking tool.
Advantages:
 Reliable and extensible database.
 Fast and safe hosting facility.

3.  Real-time data synchronization.
 Requires a very low initial effort for setup.
4. SQLite
SQLite is a relational database management system that generally follows the
PostgreSQL syntax. As the name suggests, SQLite is a lightweight database
designed especially for mobile applications. The database requires minimal
setup, andthe developerscan integrate it within their mobile apps.Today,many
React Native developers are using this database worldwide.
Advantages:
 ACID-compliant database with SQL standards.
 Allows offline data persistence.
 High reliability and accessibility.
 Source code is available to all free of cost.
5. Realm
If you’relooking to develop any real-time or offline application that can run on
wearables and mobile devices, then Realm can be your best bet. The database
comes with its own set of engines and doesn’t rely on key-value storage. This is
oneof the reasonswhymany React Nativedevelopers chooseRealm as the local
database for mobile app development in Dallas.
Advantages:
 Multiple encryption standards for various platforms.
 Offline-friendly database with Redux offline.
 Great sync service that saves all user interactions.
 Provides you with a great set of APIs.

4. 6. Vasern
Vasern is one of the most lightweight, fast, local open-source databases for
React Native app development. Although Vasern is an excellent choice for local
storage, it also has a provision for cloud storageand app synchronization. Ithas
taken inspiration from various open-sourcedatabases, and that’s why you will
see many popular features of those databases in Vasern.
Advantages:
 End-to-end database encryption facility.
 Primary focus on optimizing app performance.
 Developer-friendly and open-source.
 Highly consistent and lightweight.
7. PouchDB
PouchDBis one of the mostpopular local React Native application development
databases that store the data in JSON format. Due to this kind of arrangement,
developing, reading, writing, updating, and deleting the database can be done
through a single JavaScript API. In addition to all these, the database is
compatible with MySQL, CouchDB, PostgreSQL, and MongoDB.
Advantages:
 Faster execution of database queries.
 Allows you to run apps both online and offline.
 Easy to learn, use and understand for a newbie.
 Open-source, lightweight, and cross-browser compatible.
8. Async Storage
Async Storageis a unique local databaseused by many React Native developers
across the globe. It allows you to store and retrieve the data between reboots
of the application. Async Storagecomes with React Native components, so you

5. don’t have to worry about deployment. Even after you have closed the
application, Async Storage can save the data that an app needs.
Advantages:
 Highly accessible and reliable database.
 Readily available and simple implementation.
 No delays in the loading of an application.
 Highly useful for MVP/POC products.
Conclusion
React Native has become the heartbeat of developers across the globe as far as
cross-platformapp developmentis concerned. Now, to makethose applications
work well, you need a reliable and accessible local database. There are many
options available forlocal databasesas far as the React Native app development
goes. Choosing the best one out of that is a tricky situation.
You should firstlist requirements for yourideal databaseand then searchacross
the variousoptionsavailable. However,if you don’twantto get in a tangle, refer
to this blog post. Here, wehaveenlisted the top local databasesfor React Native
app development. This will make your job easier than ever before.
