This document serves as a comprehensive guide for selecting the right database for React Native applications, highlighting options like Realm, Firebase, and SQLite. Each database is analyzed for its features, advantages, and suitability for different project needs, emphasizing performance, offline capabilities, and integration ease. The guide concludes with key considerations for developers to evaluate when choosing a database for their React Native projects.

FOR YOUR REACT
NATIVE APP

2. From SMEs to Large-scale
organizations are using React Native
to build their business applications,
and more and more businesses
are adopting React native for the
same. As React Native is the most
suitable choice for entrepreneurs,
we are here to help you ease out your
considerations with React Native
databases.

3. If you are wondering, Is there a
programming language best suited to
developing apps? The answer is yes, it
is React Native. In today’s digital
world, developers are under the
immense pressure of developing
high-performing offline apps that can
be scaled whenever needed. To build
such scalable apps, you are required
to have a database that synchronizes
data offline, is reliable, performs
highly, and the one that is secure
enough when it comes to integrating
with other stacks. In this blog post, we
are going to bring to your knowledge
the top React Native Databases for
2020.

4. Top Local
Databases for
React Native App
Development

5. Realm

6. The realm is an open-source and
object-oriented database which
makes it 10 times faster than
relational databases. You can use the
realm database as a query-free
database.
Realm supports complex data types
for offline apps and real-time
applications. One can customize this
database for iOS, Android, and
Javascript. It has its own database
engine and doesn’t rely on key-value
stores or object-relational mapping,
or is not built on top of SQLite.

7. Developers choose the Realm
database for their high performance
React applications that need to
handle extensive data. The
combination of Realm and React, of
all other databases available, is best
for large-sized applications.
The Realm pro comes with advanced
features that cost $1750 per month.

8. Benefits of using
Realm database
Realm Synchronization offline
offline-first architecture
Secure

9. Firebase

10. Firebase is a Google-owned NoSQL
database for React. This database is
cloud-hosted, and hence it hosts and
syncs data across multiple devices in
real-time. Firebase is well-suited for
multi-user, super-collaborative apps
which have high-availability
requirements.
Firebase consists of a minimal-setup
cross-platform API, with which, you
can create serverless apps very
quickly. It transports all your data
over Secure Socket Layer SSL and
thus takes care of data security.

11. Firebase fulfills the requirements of
the model and controller of the
Model-View-Controller MVC
architecture in react native
applications. Firebase is free up to 1
GB data, costs $25 for up to GB data,
and there is a pay-as-you-go package
too.

12. Benefits of using
Firebase
Real-time data synchronization
Minimal setup
Offline persistence capabilities

13. SQLite

14. This one is a relational database
management system that was
designed to meet the local storage
demands of mobile apps. It has a
lightweight library based database
that needs a minimal setup. It can also
be directly connected with mobile
applications for direct access to the
database.
SQLite is an open-source and free-to-
use database unless you want to buy a
licensed version to obtain a copyright.
Then you need to pay a one-time fee
of $6000.

15. The Pros of
choosing SQLite
ACID (atomicity, consistency, isolation, and
durability)-compliance
Offline persistence

16. PouchDB

17. The PouchDB is an open-source
Javascript database, based on the
CouchDB for React applications. It
stores data in the JSON format, and
developers can undertake any CRUD
operations on the query via a single
Javascript API.
The PouchDB, apart from being the
most compatible with CouchDB, is
also compatible with MySQL,
PostgreSQL, and MongoDB serverside
databases.

18. The advantages of
using PouchDB
Easy synchronization with multiple platforms
Replication like a pro

19. Async
Storage Class

20. This is an in-built storage class that
comes with React native; hence you
can use it without any external
deployment. All the objects saved in
the Async Storage class are in the
string format. Developers must
serialize them before storing and
deserialize before retrieving data.
It ideally takes time in serialization,
and this makes Asynch Storage
Classless preferable for a large
amount of data.

21. Benefits of Async
Built-in
Handy when needed

22. Watermelon
DB

23. The Watermelon DB is built on SQLite
and is a high-performance database
for React Native apps. It has the
potential to scale thousands of data
records without bargaining on its
speed.
This database highly focuses on real-
world performance and has been
optimized for React Native apps that
are complex.

24. Benefits of
Watermelon DB
Offline-first system by plugging your sync
engine
Easily plug data into components
Static typing with flow
Building apps on SQLite foundation

25. Vasern

26. Of all React Native App databases,
Vasern is the most lightweight, along
with being open-source and fast.
Developers use it for data storage,
cloud storage, and syncing across
App’s clients.
Vasern is built using Golang- the
server-side language created by
Google.

27. Perks of using
Vasern
Uses UTF-8 encoding and supports
languages
Support for all the basic datatypes

28. Oracle
Berkley DB

29. Berkeley DB is a backend for React
Native, which is high performing and
open-source. Developers can use it to
handle data in multiple ways.
Oracle supported the SQLite by
adding API and included in the
Berkeley DB.

30. Advantages of
using Berkeley DB
Highly flexible
Fast, reliable, and scalable

31. Now that we have shared with you the
specifications of all the possible
databases that you can use with your
React Native application, it is up to
you to decide which one is the right fit
for your requirements.
Finally, we would like to remind you
of the factors you should consider
before finalizing your database.

32. Factors to consider before
choosing a Database for your
React App
Data Complexity
Ease of Use
Synchronization of Offline Data
Concurrency and handling Data Conflicts
Memory Management

33. Wrapping Up
So, now you know what matters for building
a highly scalable React Application for your
business idea. If you are looking for the best
React Native developers who are well-versed
with top-of-the-line React Native
development services, then hire dedicated
React Native developers from us to build a
