React
Native has become the most talked-about technology in the last couple of years
and its popularity as a cross-platform framework owing to cost efficiency has
made React Native Development the most preferred development technology in
mobile app development companies. Due to the ever-growing demand, it is
expected from the developers to build highly performant apps. One of the
challenging decisions while architecting React Native apps is to select the
right database for the project. The good news is, that the React Native
framework comes with some really good choices available for data storage. So,
in this blog, we will shed light on top React Native databases for 2021. Let’s
explore them in detail. But before that, let’s quickly run through the significant
factors that a React
Native app development company should consider while choosing the apt
database for React Native App Development.
Variables
to be considered while choosing the Apt Database for Your Project
Data
and App Complexity: complex data
sets in the applications can cause severe app performance issues. So, databases
that can store complex data should be chosen. Apps that have lower complexity
can use simple databases so that such apps can be easily synced with the
server. But complicated apps with multiple-user collaboration requirements
require a complex database for ensuring seamless syncing.
Memory
Handling: inadequate database memory management
can lead to the crashing of apps. Hence, it should be ensured that memory
management is done efficiently through processes like compaction, garbage
collection, etc.
Line
of Codes: if a higher number of code lines are
used in a project for CRUD like operations, then an advanced database should
not be the choice as the coding gets more cumbersome. This code complication
deteriorates the performance of the app significantly.
Data
Conflicts: the possibility of data conflicts
increases when more collaboration related features are added to the app and
data is being used concurrently. So, it is always good to select a database
that handles data conflicts and concurrency and shares the conflict handling
policies on the website or at least on repository pages.

React Native Databases for 2021!
Realm
Realm
is an object-oriented database that enables the creation of real-time and
offline applications that run on both- wearable devices as well as smartphones.
It is one of the top React Native databases amongst all the available ones.
This database is highly preferred when the end goal of the project is building
high-performance apps that can deal with a huge data flow. The database
benefits both platforms- iOS and Android. It doesn’t depend on key-value stores
as it has its own database engine. Realm allows
the React Native app developers to frequently undergo tables, mapping classes,
fields, foreign keys, etc.
Key Advantages of Realm:
- Makes use of multiple encryption standards to ensure good security for diverse mobile platforms
- Realm Synchronization service works locally in the background for recording user interactions and service requests and sends the data to the server after the device goes online.
- Redux offline can be used to fulfill offline-first architecture requirements.
Firebase
For
React Native development, Firebase supports real-time NoSQL DB. This database is known
for its offline data modifications and data synchronization capabilities.
Besides, it can handle M (model) and C (controller) of the MVC that is needed
while building React Native applications.
Key Advantages of Firebase:
- This database allows real-time data syncing for all the clients simultaneously.
- Firebase offers a cross-platform API that can be easily set-up with minimum effort.
- Firebase database can be directly accessed with a mobile device and so, the application servers are not needed.
- Firebase supports the creation of real-time apps with offline persistence capabilities.
SQlite
SQLite
is a relational database management system developed for offering local storage
to React Native applications. ‘Lite’ in SQLite depicts the light-weight nature
of this database. Also, this database is very easy to setup. It can be directly
integrated with the mobile applications for accessing the database. For data
encryption, SQLite can be used
with an extension called SQLite Encryption
Extension (SEE).
Key Advantages of SQLite:
- This database can support offline persistence, simply by using a react-native-SQLite-storage plugin for data management within the mobile app.
- SQLite is ACID-compliant and employs most of the SQL standards with just a few omissions. It comes with a file-based library architecture and some tools for easily and efficiently handling all data types.
PouchDB
This
is a Java script database developed using a storage mechanism and CouchDB
protocols. It stores the data in JSON format. This open-source database enables
the React Native developers to read, create, delete, update, and query the
objects using a singleJS API. Furthermore, PouchDB
is compatible with MongoDB, CouchDB, PostgreSQL, and MySQL.
Key Advantages of PouchDB:
- It allows data syncing using a supported server for running the apps online as well as offline.
- Ensures speedier execution of queries.
- Also, as PouchDB remains inside a browser, it is not necessary to run queries over the network resulting in faster execution of queries.
Vasern
This
is an open-source, lightweight, and fast database used for React Native based
application development for both- Android and iOS. It is developed with a robust server-side language-Golang, created by
Google. Vasern’s API can also be utilized for syncing across app clients, local
storage, and for cloud storage.
Key Advantages of Vasern:
- Vasern ensures good performance of apps and speedier operations
- Provides end-to-end database syncing
- Support basic data-types like string, double, int, double, reference, datetime, etc.
- Provides support to languages that use UTF – 8 coding.
Watermelon
DB
This
database is built on top of SQLite. It can scale a myriad number of records
without impacting the application speed. This is perfectly optimized for the
creation of complicated React Native apps with real-world performance.
Key Advantages of Watermelon DB:
- It is a fast, multi-threaded, relational, and highly cached database.
- It supports an offline first system for syncing with your own backend.
- It allows static typing with flow
BerkeleyDB
This
is a high-performing backend and allows the React Native developers to handle
data in several ways. It comes with an API that is compatible with numerous
languages and several platforms like Android and iOS.
Key Advantages of BerkeleyDB:
- Simple to use
- Provides support for industrial-strength transactions
- Ensures concurrent access for multiple users
AsyncStorage
This
is a local storage database and comes in-built with React Native. It enables
React Native developers to persist data between reboots of the apps. It acts as
an outstanding solution for saving the data that the app required, even when
the app is being closed by the users.
Concluding
Views:
Apart
from the local databases mentioned here, there are several other databases
available for the React Native app developers to utilize in their projects.
But, the choice of a database used for React
Native mobile app development ultimately depends on the project
requirement, its scope, and end goals. For instance, Firebase suits perfectly
when one has to develop real-time apps. Realm is great for almost every
possible requirement, but comparatively, SQLite doesn’t provide the same level
of performance, scalability, and security. Rather SQLite is good to go with
when one requires to leverage the abilities of a relational database. So, the
one that suits your requirements is the best choice for you.
