Top Databases for React Native App Development
React Native is one of the most used frameworks
when it comes to app development. It is a
perfect solution for startups as well as
enterprise businesses to develop applications.
Many companies have already leveraged React
Native and have developed interactive
applications.
When talking about React Native app development,
there are multiple things that go into it. One
of the major and most important parts is the
database. More complex the data, the more secure
your database must be. In this article, I will
walk

you through different factors one must consider
while selecting a database and which is the
perfect solution for your application. Factors
to Consider While Choosing Database Line of
Codes Line of codes de?nes other things you use
for React Native App development. If you write
less than 20 to 40 lines of code for simple CRUD
operations then prefer not to use any advanced
database. Because using advanced databases for
small CRUD operations will make your coding more
complicated. Handling Data Con?icts and
Concurrency More collaboration features means
more possibilities of data con?icts. Look for
databases that share the con?ict handling
policies on their website or repository pages.
Learn more about database documents and become
aware of how they handle data syncing and
con?icts. This will help you decide on the
correct database for your application.

Memory Management Regardless of the database you
use, you need to make sure that it has good
memory management. Inef?cient database memory
handling can often lead to app crashes. If you
think your database is not managing memory
ef?ciently, you can do a compaction
process. Compaction is a proactive process for
memory management in which it deletes certain
documents that are of no use. This will empty
some memory from the database and the app will
work better. This process is similar to the
Garbage Collection part of programming which
makes sure the memory is available to
users. Complexity of Data When working with
server-side or client-side scripting languages,
key-value or JSON structure is the default option
for storage in most of the databases. React
Native developer or in-built library will
serialize the strings. Oftentimes serialization
can cause serious halts and issues in application
performance because of its limited resources.
This is one of the major reasons behind
companies using a database that
4
helps to store complex data like documents,
objects, and other complex data types. Syncing
Data Of?ine Today users want their applications
to work of?ine as well. Hence, it is important
to use databases that sync with your application
when users connect with the internet. To do so,
you also need to make sure that the of?ine
database is secure as data will be stored on
users phones. These are some of the major
factors you need to consider when selecting the
database. Understand your customer and apps
requirements and then make the decision of
?nalizing the database. Going further, lets
talk about different databases you can use in
your React Native app development Realm Realm
is an object-oriented and open source database
that is useful to develop iOS and Android
applications. Realm databases gave birth to
real-time and of?ine applications that run on
mobile devices and wearable devices. It operates
10
5

• times faster than relational databases and
  supports complicated data types too.
• Realm also has its own database search engine
  which makes it easy to access any sources or
  threads. Developers prefer to use Realm
  databases to improve the performance of React
  Native applications by dealing with huge amounts
  of data. As it is a high-performing database,
  Realm has proven to ?x the queries better and
  easily, compared to other databases. Realm is
  the best database choice for large-sized apps
  because of its open-source nature and is easy to
  use. Some of the bene?ts of using Realm are
• It synchronizes in the background and saves
  users interaction.
• It has a great set of APIs.
• It is an of?ine-friendly database.
• Uses different encryption standards for different
  mobile devices.

6

• Firebase
• Google-based Firebase database has NoSQL and is a
  perfect database if your application is more
  into of?ine data updating and synchronization.
  It also manages MVC-based React Native
  applications that have high data requirements.
  Additionally, it even has a feature like
  tracking tools which helps you to ?nd bugs in
  your application and remove if any. Additionally,
  it will even provide you full access to data
  removal from Google servers whenever you need
  it.
• Following are some of the major bene?ts of the
  Firebase database
• It can address users role that will help you to
  ?x control on ?les.
• You can integrate Firebase with any application.
• It caches data on devices to provide users of?ine
  access to your software.
• It synchronizes the data from different platforms.

7

• SQLite
• The main aim of SQLite was to offer users the
  capacity to make local storage databases for
  mobile devices. Lite stands for a lightweight
  database that needs minimal setup. SQLite
  executes SQL policies with extra tools which help
  you to manage data easily. The performance of
  the database is not great but developers can
  make necessary changes as it is open-source.
  Following are the key bene?ts of using SQLite
• It saves data in a cross-platform database ?le.
• You can use it to store and synchronize data for
  of?ine apps.
• Being ACID-compliant it executes all SQL
  standards.
• PouchDB
• It is an open-source JavaScript database that
  preserves data in JSON format and enables CRUD
  operations via simple JS API. PouchDB allows
  apps to store data locally even when it is
  of?ine and syncs with compatible servers and
  CouchDB when the app connects with the internet.
  It keeps all users data synchronized as it is
  lightweight. It also helps to secure data

8

• easily for React Native applications and has an
  in-built authentication system. This system
  provides features like password storing using
  the latest encryption algorithms.
• Following are some of the major advantages of
  PouchDB
• It syncs data with the supported server.
• PouchDB is built on CouchDB protocols and
  supports of?ine and online capacities.
• It supports SSL, which means you can encrypt data
  using the AES256 encryption technique.
• You can easily replicate data from PouchDB.
• WatermelonDB
• WatermelonDB was built with an aim to optimize
  React Native databases. It is developed on
  SQLite and works great with React Native
  databases. WatermelonDB can scale thousands of
  records in a minute and can create complex apps.
  This database can handle cached and
  multithreaded async functions. Following are
  some of the bene?ts of WatermelonDB

9

• It has static typing with ?ow.
• You can of?ine the ?rst system by synchronizing
  your engine.
• Simple data can plug into components.
• If there are any changes in the database, the UI
  will reload automatically.
• Vasern
• Vasern is the most lightweight, open-source, and
  fast database for developing React Native
  applications. The Vasern API is useful for local
  storage as well as syncing and cloud storage
  across the app users. The structures and design
  of WatermelonDB get inspiration from different
  open-source databases. Following are some of the
  bene?ts of Vasern
• It operates fast.
• It has an end-to-end database and is
  developer-friendly
• i.e. developers can customize it according to
  their needs.
• It provides better app performance and
  consistency.

BerkeleyDB It is an open-source,
high-performance backend database for React
Native which allows developers to handle data in
multiple ways. It also offers an API for multiple
languages which includes iOS and Android.
BerkeleyDB can also handle data in multiple ways
like SQLite. It uses Key-value pair data and
also has a byte array and supports multiple data
items for a single key. AsyncStorage AsyncStora
ge is the asynchronous, unencrypted, key-value
pair database used in React Native instead of
LocalStorage. Persisting data in a mobile
application has bene?ts like when the user
restarts the app, the data or the setting
variable is available to the user just the way
they used before closing an app. Wrapping
Up When starting with React Native app
development, deciding on a database is the most
vital thing as it includes users data. When
deciding which database to use, take the above
factors into account and also apps
requirements. The database is the
11
most crucial part as it needs to handle all the
complex operations and keep data secure,
synchronized, and available of?ine. If you need
