React Native has become the most talked-about technology in the last couple of years. Its popularity as a cross-platform framework due to cost efficiency has made React Native Development the most preferred development technology in the tech world. Due to the ever-growing demand, developers are expected 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 2022. Let’s explore them in detail. But before that, let’s quickly run through the significant factors that should be considered while choosing the apt database for React Native projects.
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.
Top Databases for React Native in 2022!
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 lightweight nature of this database. Also, this database is very easy to set up. It can be directly integrated with 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 JavaScript 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.

We’re living in an API-centric world. Many of our daily activities revolve around APIs, and most of us are not even aware of it!
Have you ever wondered how the following actions are executed?
You can instantly browse information on the current weather conditions as well as the weather forecast using platforms like Apple’s weather app, Google search, or smart home devices.
The travel booking websites aggregate numerous destinations and flights right away for displaying the cheapest option to you.
You can log in to certain websites and mobile apps using the profile login details of your Google/Facebook/Twitter account.
You can play Spotify while using the Uber app.
Well, the common component responsible for all these prompt and useful actions is an API! APIs connect two distanced entities and enable them to communicate with each other in a standardized format. APIs reduce a considerable amount of time and effort to securely exchange data. For instance, weather booking sites collect information from a third party via APIs, and the weather data is sent to them in a manner that can be easily reformatted. Travel booking sites use third-party APIs for gathering information on the availability of flights and hotels directly from the providers. A website can leverage the API of popular services like Google or Facebook to authenticate a user so that users do not have to bear the hassles of creating a new profile for every website service. Likewise, Uber uses an API to connect with Spotify.
So, what is an API, how does it work, and why is it important? This post answers them all! Read along to gain comprehensive insights on an API, its functioning, and its importance from the perspective of developers and businesses.
The Basic Principle of an API
An Application Programming Interface, commonly known as an API, is a software intermediary that enables computers/computer programs to communicate with one another. In other words, an API contains a set of functions using which apps can access data and can interact with various OSs, external software components, or microservices.
When one uses an app using a smartphone device, the app sends data to the server using the internet. The server retrieves this data, then interprets the data, carries on the required actions, and finally sends the data back to the user’s mobile device. Now, the app interprets this data and displays the information requested by the user in a readable format. All the aforementioned actions are made possible by an API.
How does an API function?
Technically, an API comprises a bunch of defined rules that instruct how software apps or computers will communicate amongst each other. An API works as the intermediary layer between an app and the web server; it processes the data transfer that takes place between the systems.
Steps on how an API works:
Step # 1
A request is placed by the user – the client app initiates an API call for retrieving information. Then the request gets processed from the app to the web server, through the URI (Uniform Resource Identifier) of the API.
Step # 2
Once a valid request is received, the API makes a call to the web server or the external program.
Step # 3
A response is then sent by the server/program to the API. This response contains the requested information.
Step # 4
Now, the API transfers this data to the app that had initiated the request for obtaining the information.
Here, the data transfer varies based on the web service used.
Example:
When you search flights online, you need to choose from different options available like departure/return dates, one-way/round trip, names of the departure & destination city, the type of seats, the number of passengers, and so on. Through these actions, you are actually interacting with the website of a particular airline and accessing their database to check the seat availability and flight fare on the desired dates.
Now, let’s discuss an instance when you are not using any specific airline’s site for directly obtaining the information; but using an online travel service to check out the deals offered by various airlines and choose the best available option. Travel services like Expedia, MakeMyTrip, Kayak, etc. aggregate information from the databases of several airlines by interacting with an airline’s API. The third-party provider will allow this interface to execute actions like acquiring information from airline databases, booking seats for passengers, etc. After receiving the request for such actions, the API will collect the airline’s response to this request and deliver the response back to the aggregator. And, thereafter the aggregator will display the updated and relevant information to the passenger.
Tips on API Development
A sound API comes with clear and concise commands that can be reused by programmers. While designing APIs, developers need to create endpoints within an API. An endpoint is an URL performing a specific kind of function. Endpoint provides a path for other fellow developers to follow and this way, the API development process is smoother, ruling out chances of confusion and guesswork.
The Modern API Development: Characteristic Traits
Today, APIs are considered more as products than codes and are created for specific sets of users like software developers. And, like any other software end-product, APIs come with their own SDLCs (software development lifecycles) – designing, development, testing, managing, and versioning. A modern API adheres to HTTPS and REST standards so that they are understood properly, can be easily accessed, and are developer-friendly and secured.
APIs ensures safe data transfer between different platforms. The endpoint of the API decouples the consuming app from the service provider’s infrastructure, API calls include authorization credentials for minimizing the threat of attacks on the server, and an API gateway is empowered to limit access for ruling out security risks. Besides, during the exchange of data, extra layers of security are employed in the form of cookies, HTTP headers, query string parameters, etc. Navigate this link to learn more about the best practices for ensuring API security.
A good API usually contains different formats as various apps communicate in different languages including CSV, XML, and JSON. Furthermore, comprehensive documentation stating an API’s usage is present to make it DevOps-friendly. Also, good APIs are supported and backed by dynamic developer communities for extending help to the ones who get stuck.
Types of APIs
Public API
Public APIs are meant to be shared with the outer world such that an external mobile app development company or developer can leverage the capabilities of these APIs for building apps. Certain firms provide semi-public access to their APIs – no public documentation is available; developers/development companies need to submit their apps for approval.
Private API
These APIs are internal ones created for specific user bases and audiences. Such APIs are used within an enterprise for enhancing collaboration and facilitating communication amongst employees. These APIs can be used by those employees who are granted access.
Why are APIs important for Developers?
No Need to Reinvent the Wheel
Ready-to-use APIs are available for all OSs including iOS, Android, and Windows to carry out most standard developmental tasks. As such, things become easier for developers; they do not have to reinvent the wheel and waste their time and efforts in API development.
For example, if developers are building an iOS application and need to embed a web browser for displaying pages on browser inside the app; they don’t have to program a web browser from scratch. All they need to do is utilize the WKWebView API for embedding a WebKit (Safari) browser object within the app. Similarly, instead of creating a camera interface separately for an app, the camera API is used for embedding the in-built iPhone camera into the application. If developers intend to provide the facility of fingerprint authentication support for an Android app, they need not test every fingerprint sensor of different Android manufacturers. They just need to use a ready-made API!
With such useful APIs, developers can acquire quite a lot of data, services, and resources while building apps. This reduces the time-to-market.
More Scope for Innovation
After integrating APIs into a system, you get an application layer for distributing pieces of information smoothly into other systems. This way, new services can be introduced to new audiences as per their ever-changing desires & needs – developers can utilize APIs for creating personalized services/features for them.
Increased Efficiency
API access enables businesses to publish the app content very quickly as the system automatically publishes content and makes it available for all channels. This way, the content reaches a wide range of audiences effortlessly and in much lesser time and cost as compared to traditional marketing practices.
Effortless Adaption
Software systems of a firm need to be updated within time and the presence of a custom API speeds up this process. Furthermore, data migration becomes easier and the information can be reviewed in a better way.
Why are APIs important for Businesses?
Workflow Automation
API integration has helped several enterprises to automate workflows and enhance workplace collaboration. The absence of APIs would have created connectivity woes and informational silos, adversely affecting performance and productivity.
Facilitates B2B Dataflows
APIs are essential for running data-driven businesses. API usage enables businesses to integrate data flows with their partner’s systems or customers. They also increase the flexibility of traditional data exchange methods like EDI and MFT.
Improved Success Rates
Several businesses maximized efficiency as well as revenue generation through joining forces with other businesses. For example, Uber didn’t waste time, money, and efforts in creating their own services like mapping, communication, or payment gateway. Instead, they utilized the best available services and integrated these services into their app via APIs. And, their success rate and profits are evident.
Bottomline:
APIs are omnipresent, empowering our daily activities from behind the scenes, without being noticed. And, most importantly, they are an integral part of today’s economy. APIs not only enable the sharing of crucial data, but also makes it possible to utilize practical business functionality between individuals, apps, and devices.

“Design is about creating shareable solutions to shared problems.”
– Mario Maruffi
Compared to the last decade, technology has grown in leaps and bounds. Desktop devices have shrunk to fit the palm of your hands, and handheld devices further shrunk to become wearable devices. This also significantly revolutionized user layouts. In addition to being responsive to the different device screen widths, a good user interface (UI) also needs to offer a good user experience (UX). Modern-day mobile users prefer mobile apps that are easy to use & navigate, quick, small in size, and also very elegant. As per the findings from Statista, annual app downloads have risen from 140.68 billion in 2016 to 230 billion in 2021.
Through years and years of refinement, mobile app design has undergone multiple changes. So, it is difficult to pinpoint what works and what doesn’t but designers specialized in user interface app designs follow a few fundamental principles of Mobile App design, and we shall look into them.
Key Components of Custom App UI/UX Design:
User Design: Includes images, color palettes, text, fonts, spacing, icons, aesthetics, graphics, videos, background, and more.
Information Architecture: Structuring based on business objectives
Interface Layout: Planning the app interface behavior and pages.
Wireframing: Testing the app’s usability, functionality, look, and features.
Page Hierarchy: Pages should have consistency, flow, and connectivity.
Usability: Ensuring maximized usability by providing users with easy app interactions.
Information Placement: Placing high-quality content effectively to maximize conversion.
Fundamentals of Mobile App Designing Conduct Ample Research
Rule of thumb, before taking up the task of creating the mobile app design, do your research. Understand the demographics, predict their behavior, study their preferences, and determine the purpose of the app. Is the app being used for communication? Can the users make purchases from the app? Is live chat integrated into the app? Does the competitor have an app? It can help them identify the flaws of the competitor apps that they can remove and gain an edge. Research is the first stepping stone towards creating a functional mobile app.
Remove the Clutter
Ever opened an app where you are flooded with information at the first instance? How quickly did you exit the app? A cluttered interface can overwhelm the user. This doesn’t mean swinging towards minimalism. The key lies in arranging elements that your user can navigate their way through the application.
Colors Have Significances
Man is an animal of habit. Tapping into our primal instincts, we tend to associate emotions with certain colors: Color red significances error or caution, especially when flashing. Similarly, yellow over light background may become illegible when seen from an arm’s length. Moreover, the use of more than three colors is strictly a no-no in the books of UI design. It is safer to use gradients when you wish to integrate more colors in your layout. Contrasting colors will help users see and comprehend your content with greater ease, translating into better usability.
Maintain Consistency
When using an app, the user tends to familiarize themselves with the different elements in the interface and apply the knowledge gained to navigate through. So it is important to maintain consistency. Designing simple, clear, and consistent navigation can be the difference between a good UX and a decent UX. Similarly, if you have a web app as well as a mobile app, it is important to ensure the transition from either to the other should be smooth, and a consistent design can help achieve it.
Pleasing UI Layout
Design elements such as fonts, color, logos, buttons are the building blocks of your interface and should be used judiciously to create your UI. You may wish to radicalize your app design and bring out-of-the-box ideas, but it is a double-edged sword. A good UX dictates that an app user should be able to manage basic tasks without jumping through UI design nuances to reach their destination. Provided that the learning curve for interacting with your app isn’t steep, “out-of-the-box” ideas are good to implement. However, this requires you to gauge your audience demographics and design accordingly.
Accessible
Buttons are a boon to interface designers as it allows them to replace ugly hyperlinks with attractive buttons. However, it is important to include text labels on the buttons as it adds further comprehension for the user.
Thumb-friendly Interface
Handhelds and wearables are the future, and this means the user interface needs to be easily interacted with using thumbs. Well-designed app interfaces are the ones that are kept in the thumb’s reach of the users. Therefore, any design elements should be kept between 7-10 mm to be accurately tapped with a finger.
Always Test your Designs
Fifty-eight percent of users are frustrated by interface inconsistencies. (Source) Sometimes what seems good on paper and in design might not be effective once deployed as a functional mobile app. Since mobile app UX design is all about the user’s emotional reaction towards the app’s design, it should be tested by real users on a variety of mobile devices.
Benefits of an optimized mobile app UI/UX design Improves Customer Acquisition and Retention
A user-friendly and intuitive UI/UX design provides you with a competitive edge and increases user trust. The customer’s enhanced trust correlates to a higher likelihood of conversion.
Increases Customer Satisfaction
Customers are becoming increasingly important to businesses. Once a company has figured out who its ideal consumers are and their wants, it can use its applications to put the customer’s needs first. Your app will keep your users engaged by providing easy navigation and compelling information.
Maximizes Productivity & Conversions
A high-performing design allows for increased productivity in terms of progress, user engagement, and sales conversion. It engages your users, leading to increased conversions and profit. Faster page loads, simple layouts, rich and immersive content, and intuitive navigation all contribute to an app’s success.
Brand Building
UX and UI encompass more than just aesthetic components, style, symbols, fonts, colors, pictures, and functionality; they also express a company’s values and ideals. Your clients will be happier if your UI/UX experience is better. Customers that have a pleasant user experience are more likely to remain loyal to your business and become brand champions. This leads to the development of a brand, a higher reputation, and increased sales.
Reduced Development Resources
Money, time, and support are all essential resources for every business. When you take a user-centered approach to your mobile app’s UX/UI design, you’ll save future difficulties and save your company money.
Maximized Revenue
Customers are always eager to pay a premium for superior service; all they need in return is a great user experience. Likewise, customers would be keen to spend money with you if your app has great functionality and an exceptional bespoke app UI/UX design. As a result, it’s best to concentrate on all possible possibilities to convert your users into purchasers and optimize your return on investment.
Wrapping Up
Designing a mobile app is no longer about resizing the desktop manifestation to suit the small display sizes. Brands are realizing that UX is above and beyond your app’s performance. The UX and UI Design will guide your users to what they are looking for, eventually increasing their engagement with your brand.
