What is React Native?
Big brands such as Instagram, Uber, Skype, etc. use it as it has grown at an astonishing pace since its launch by Facebook in 2015.
According to a 2020 developer survey, global developers widely used React Native as the most popular cross-platform mobile framework. In fact, 42% of developers used it to build high-functioning apps in 2020.
Moreover, there are extensive benefits of React Native for app development and is one of the most sought-after frameworks in the market today.
Factors/Features to Look for in a React Native Local Database
There are a few factors to keep in mind while choosing the right database for React Native:
Data complexity managed: The right database should be able to manage complicated data structures like full documents or objects. Either key values or a JSON structure preserve the data, making it important.
Memory management/ handling abilities: One of the topmost reasons for an app crashing is poor data management. Thus, the DB should be able to manage memory properly.
Offline data synchronization: With more and more users seeking apps that work in offline mode or with a slower internet connection, it has become important to integrate a database that allows data synchronization when users reconnect to the internet.
Management of data conflicts and concurrency: Data conflicts arise due to excessive collaboration features included in the app. Thus, databases that share conflict-handling policies on their websites or repository pages, should be chosen.
Lines of code: The database should be able to carry out functions with minimum lines of code, enhancing its performance and the overall development costs of React Native apps. Processing a lot of code lines would eventually slow down the app, which is mostly the case with advanced DBs.
Ease of use: The right RN database should facilitate integration with the least amount of effort. This helps in speeding up the development process and making the developers’ jobs much easier.
Top 6 RN Local Databases for App Development
One of the best databases for React Native, Realm is an object-oriented database that was launched back in 2004. It offers support in the development of real-time and offline apps by managing complicated data types, for wearables and mobile devices. The database allows RN app development for both platforms, iOS and Android.
It comes with its own search engines, eliminating the need for key-value store or object-related mapping. This is the most preferred choice for apps heavy on data or to ensure the high performance of the application.
It is the best at fixing queries among all the other databases and is the best choice for large-sized apps.
The realm database is used by Patreon, N26, Peek Stack, etc.

Additionally, offers a minimum price of $25 for 2.5 GB of data storage as well as a pay-as-you-go package.
A software library, SQLite works with a serverless and zero-configuration transactional database engine that is written in C language. It offers huge storage for mobile apps and writes content directly into files instead of the server. Stored in plain text, the content can be encrypted with an SQLite extension named SEE (SQLite Encryption Extension) or SQLiteCrypt, etc., to offer app security.
The word Lite in the name of the database highlights how lightweight the library is, and the minimal setup efforts required. The database follows maximum SQL policies with additional tools that assist developers in the easy management of the data.
SQLite is used by brands like Alibaba Travels, Accenture, and NetSuite Inc.

Q1. What is react native local database?
Local databases are a local copy of a database that comes with classifications of certain Data Types and is downloaded through Partner via the SDK. They provide a lightweight, self-contained SQL database engine, that is used by the appl logic in your triggers for a wide range of tasks.
React Native local database is software that is specific to React Native applications. It employs an SDF data file and has several databases available such as Realm, Firebase, SQLite, etc.
Q2. What role do local databases play in react native app development?
The role a local database plays in React native app development depends upon the type of app, the level of complexity, and the allocated budget. While general role played by them is to help to bring the app’s data offline, allowing users to gain a smoother and faster app experience, among other things.
