Which Databases Are Compatible With React Native App Development?

Mobile App Development

Monday, 07 September 2020

React Native has been the choice for cross-platform app development right since its inception (March 2015). It is a JavaScript-based mobile app development framework that enables natively-rendered mobile apps for iOS and Android. It lets developers create applications that can run on multiple platforms (Android/iOS). RN has been the fuel behind apps like Facebook, Instagram, Skype, Uber, Microsoft, Zynga etc because of its capability to translate huge time and resource savings.

RN owes a lot to the presence of JavaScript Library empowering frontend developers to work with web-based technologies and create robust, production-ready solutions that can be accessed across platforms. It saves costs, reduced time and efforts to migrate or reduce the codebase.

Why is React Native Still Preferable as a Cross-platform App Development Framework?

Many organizations initially wanted their development teams to create an offline-first application and then scale it further to include the online capability and more complex features to make it accessible across networks and operating systems. Developers, therefore, need to select an appropriate technology stack, with database and backend being the backbone of the application, considering that it will still be able to accommodate users if the number grows. Small to medium scale companies still find React Native development as a reliant option for hybrid app development.

How performant is it?

Native Experience

Slow in comparison to React Native

The performance is stable.

Slower in comparison to others.

Is the app testable?

Real Mobile Devices or Emulator is required to test the React Native App

By using any browser you can test the code.

Testing can be done using Mobile Apps.

Testing can be done using browsers, mobile devices or emulators.

How compatible is it with the hardware?

React Native does not require supporting techniques.

It makes use of Apache Cordova

It requires an SDK kit.

Frequent rendering slows the app.

Can the code be reused?

All of the platform-specific code requires a change.

Code is optimally used

It allows reusing 95% of the code.

Existing native libraries can be reused.

What Problems Does React Native Resolve?

React Native is inherently created to resolve core issues like extended iteration period, imperative programming, and some minor or major differences in the codebase.

  • It optimizes app development cost
  • The RN app comes with a shorter time to market cycle
  • It necessarily does not come along with a post-launch upgrade
  • Instant App Updates on users’ phones (as JS is a browser scripting language) – CodePush SDK that is integrated with the React Native app gives push notifications to the RN apps.
  • The React Native Applications have lower app load times owing to the JavaScript integrations with the native environment
  • The RN code can be reused across platforms
  • The React Native App’s state can be saved with hot/live reloading feature

Technology Stack That Goes with React Native (Illustrative)

  • Coding Tools / Editors: Xcode
  • Version Control: GitLab
  • Programming Languages: Swift, Objective-C
  • Frameworks: UIKit, UIFoundation, Cocoa, Cocoa-Touch, Location Manager, Notifications, Cocoa
  • Operating Systems: Mac, Windows, Android, iOS etc.
  • Database Systems: SQLite, CoreData, UserDefault, FireBase-DataBase
  • Payment Gateways: Stripe, PayPal, Rave-Payment SDK, Apple Pay, In-App purchases
  • CMS: CakePHP, PHP, Lumen (Laravel), NodeJS
  • Scripting Languages: JavaScript, JSX, React.js
  • Design Pattern: MVC, MVVM
  • SDK’s: FireBase SDKs, AWS native SDK, Chat with FireBase & XMPP, Socket-IO
  • Third-Party API's: Google API, Facebook API, Linkedin API

What Factors Should be Considered While Selecting a Database for React Native App Development?

It is important to evaluate whether the database will be able to handle the project complexity, the number of users, the load times,  number of server-side and client-side scripting languages in the first order, the number of code lines, capability to manage memory, Handling Data Conflicts and Concurrency, Synching of the Offline Data, the database and the conflict-handling policies as well as whether you are planning to go for the server-side or local database.

What Options are Available for React Native App Development?

The local data storage options for React Native Apps include RealM, Firebase, SQLite, PouchDB, AsyncStorage class, Watermelon DB and Vasern. The most popular ones are discussed here (In no particular order):

  • Firebase

What is it: Firebase supports as a real-time No-SQL database for React Native.

Why is it preferable for React Native App Development:

It helps in data synchronization and offline data modification. It also helps to fulfil any requirements to serve as a Model View Controller for RN applications. It also comes with a cross-platform API for setup. This makes it easily accessible from any mobile device. Firebase up to 1GB is completely free and the basic plans start at $25/month.

  • Realm

What is it: Realm can be perceived as a local database suitable for offline and real-time mobile applications. It has been built on top of SQLite with its database engine which gives it the properties of being suitable for object-oriented tasks and not very much inclined towards relational queries.  

Why is it preferable to React Native App Development: It works well under load, with many users involved and lots of data. It comes with a standard price of $25/month which starts after the first-month free trial.

  • SQLite

What is it: It was created for its ability to create a local storage database for mobile applications.

Why is it preferable to React Native App Development: It is preferred because it requires minimal setup and implements maximum SQL standards to handle complex data. It is highly performant and provides great database experience. It is open-source and free to be used. 

  • MongoDB

What is it: It is a server-side database that is built to handle large applications. It makes use of a key-value store and a relational database to store objects with dynamic schemas in JSON documents.

Why is it preferable for React Native App Development:

This database is preferable if the mobile app has a scope to be scaled up in the future. The pricing depends upon your particular cloud deployment and can be checked up on MongoDB's official website.

  • Amazon DynamoDB

What is it: It is a NoSQL server-side database that is designed to run on the Amazon Web Services cloud platform.

Why is it preferable for React Native App Development:

It is decentralized and rarely requires any sort of administration. It charges per GB disk space and provides 25 GB free for the first-month usage. Further, the price accelerates at $0.25 per GB/month thereafter.

Conclusive: Which React Native Database is the Best for RN App Development?

React Native App Development Companies select the database once they are aware of the scope and intent of the application plus specific requirements. Each one of the databases discussed above is suitable for React Native application with minor tweaks and goes well if you want to develop a native application in real-time. To summarize:

  • Realm works well for every app requirement.
  • SQLite and CoreData do not match up on performance, security, scalability like Realm but is suitable if you want all flavours of a relational database.
  • Firebase is the best to create a real-time application
  • MySQL is suitable for small applications but it is not as efficient to handle large volumes of data and also lacks speed. But it is flexible, provides reliable data protection and high availability.
