A React Native Developer is under extreme pressure for delivering a high-performing, offline-first app that can be scaled anytime. Hence, sometimes it becomes difficult for developers to opt for the relevant technology stack incorporating the right database for React Native.

In this blog, I have compiled a list of databases for react native app development. They might match your needs like scaling easily with your user base or supporting offline development capacities.

However, before discussing the best local databases for react native app development, let’s highlight the factors you should consider!

Factors to Consider While Choosing a Database for React Native App Development

Here are some aspects to take note of while choosing the best database for React Native app:

Memory Handling

If data is not handled properly, apps may get crashed more. Albeit maximum databases usually clear their cache in time intervals which makes sure that sufficient memory is accessible for running an app properly.

Complexity of Data

It is assessed that for maximum applications, data is preserved either in the form of key values or a JSON structure. This makes it essential to select a database that can manage complicated data structures like full documents or objects.

Managing Data Conflicts

If you add more cooperation related features inside the app, you may experience more data conflicts. You must seek React Native databases that share the conflict management rules on the repository pages or website.

Delve into the database documents to beware of the ways they manage syncing and conflicts or explore the trade-offs that are created and the impact it would create on the app.

Syncing Data Offline

Presently, users need their apps to work in offline mode also or when their internet connectivity is slow. Thereby, it is important to integrate the database that allows data synchronization when users have connected again to the internet.


When an application becomes popular, developers’ responsibilities increase and they need to manage a massive amount of data. Many requests will come from users and it’s very difficult to provide precise data to them.

Hence, it’s extremely essential to learn about the concurrency method applied by various React Native local databases.

Ease of Use

You should always select a React Native database that can be combined with fewer efforts. This will help you improve the development procedure and simplify the developers’ job.

Types of Databases for React Native App Development

Developing a React Native app involves crucial decisions about database management. Choosing the right database is crucial for creating responsive, feature-rich applications that meet both user expectations and business needs. Here are the types of databases commonly used for React Native applications:

  • Local Database
  • Server-Side Database

Let us explore some of the best React Native databases for local or server-side data management.

Best Local Databases for React Native App Development

Building a seamless and engaging React Native app often hinges on smart data management. Local databases play a crucial role in this by offering functionalities that enhance user experience and app performance. Here are some of the best local databases for React Native applications:

Firebase is a Google-owned database having NoSQL. If your application is more into offline data updating and data synchronization, Firebase will suit you best. Firebase can significantly manage MVC-based React Native apps that have high data requirements.

Moreover, Firebase features performance tracking tools that will help you assess a bug in your application. It gives you full access to data removal from the Google server whenever required.

The assessment procedure done by Firebase is ISO 27001 and SOC1, SOC2, and SOC3. This database is free for using up to 1GB and then you have to pay $25 for storing almost 2.5GB of data.

Benefits of Firebase

  • It can address users’ roles that will help you fix controls on file.
  • You can combine Firebase with any app easily.
  • It caches the data on devices to offer offline access to users.
  • It helps synchronize the data throughout different platforms.

This was originally built to offer users the capacity of making local storage databases for mobile apps. In the name, ‘Lite’ stands for the database’s lightweight, which needs a minimal setup. It executes maximum SQL policies with extra tools that help you manage the data easily.

Although its performance quality is debatable, greater results can be accomplished for people who have encountered amazing database development. SQLite source code is free for everybody to utilize for any reason and it is in the public domain.

Benefits of SQLite

  • It saves data in the cross-platform database file.
  • You can allow the offline persistence in an app using its storage.
  • It is ACID compliant; hence, executes nearly all SQL standards.

4. PouchDB


This is an open-source JavaScript database. It preserves data in JSON format and enables all CRUD (Create, Read, Update, Delete) functions to be queried and mutated using a simple JS API.

PouchDB allows apps to store data locally even while offline and then sync it with compatible servers and CouchDB when the app is again online, keeping all user data synchronized regardless of where they log in next. As a dependency, PouchDB is lightweight.

It helps secure data easily for a React Native app. It has an in-built authentication system for React Native and it provides features like password storing in the harsh form with the PBKDF2 crypto algorithm for protecting encrypted keys from degraded attacks.

Benefits of PouchDB

  • It helps sync data with any supported server.
  • PouchDB is made with CouchDB protocols and supports both offline and online capacities.
  • It supports SSL, which implies that you can encrypt data easily with AES256.
  • It helps replicate data like a pro.

5. Async Storage

It’s a local storage framework that enables developers to store data locally and retrieve it between reboots of an application. This database features React Native in-built; hence, you can use it without anymore deployment.

Even after you have closed the device or app, Async Storage comes in handy when you need to save the data the app has to use.

Benefits of Async Storage

  • It is accessible whenever required.
  • It is in-built with React Native.

6. Couchbase Lite


This is a NoSQL JSON document database used by developers as a standalone embedded DB accessed through iOS and Android native APIs. It’s designed for developing mobile and IoT apps.
