React Native App Development
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.

Top React Native Databases for 2021!

React Native Databases
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.
Here we come to an end! We hope this write-up was insightful.

Top Angular App Development Blunders that can Ruin Your Project

Top Angular App Development Blunders that can Ruin Your Project
Angular app development company
Angular is one of the most popular JavaScript frameworks, which offers myriad benefits to businesses worldwide. Most businesses prefer using Angular for mobile app development. Numerous giants in the corporate world have used Angularjs app development services for a wide range of projects. Take a look at some examples:
  • Video-streaming applications like NetFlix and YouTube
  • Online Payment application like PayPal
  • Travel application like JetBlue
  • A User-review application like GoodFilms
  • eCommerce applications like Land send, iStock, etc.
  • Job-portal like Upwork
Moreover, it is being predicted that Angular’s demand is going to rise further in the coming years. We can see that Angular’s future looks bright.
But despite the ever-increasing demand and popularity, there are some flaws in this framework like any other framework As such, developers tend to commit certain errors that may ruin your project. So, Angular developers and Angular development services must be aware of these common development blunders so that they are able to create top-grade applications.
In this blog, we have outlined the most common mistakes committed by Angular developers during the mobile app development process. So let’s get started.

Noteworthy Mistakes that Angular Developers tend to commit

Angular app development

Direct Manipulation of DOM

Another blunder that the developers tend to commit is making the changes directly in DOM. While changing the titles in pages or adding images, some developers may make modifications directly in DOM. But it is considered a bad practice. The DOM is a browser-specific API. It may tightly couple the Angular app’s code with the browser and this won’t allow the developers to target any other rendering environment later.

Lack of knowledge of Important Tools

This is one of the basic requirements that an Angular app development company must look into the developers while hiring.
Effective usage of the available development tools in Angular like Protractor and TestWhizin Angular helps in successful project development. Lack of knowledge on any of these tools or inability to use them can result in critical issues sooner or later. It affects project management, error handling in the project, the performance of the end product, and much more.

Improper Code-organization

In Angular, organizing the code into small chunks is considered beneficial as it simplifies the development process and also helps to track any errors and resolve them easily. This approach is much useful when several developers work on the same project. But since this framework uses MVC architecture, at times the developers may add excessive code to a single controller. Such an improper distribution of code may create issues in the later stages of development.

Cleaning up the Subscriptions

Unsubscribing to the unnecessary and older subscriptions is also a vital step in Angular development. The developers must clean up such subscriptions from time-to-time as these can cause a threat to data security and lead to several other issues. They should also avoid new subscriptions constantly.

Declaring Functions Incorrectly

Sometimes, the developers fail to assign the functions to a specific variable. In such cases, the code is at risk of being manipulated. So, it is essential to properly declare functions to the variables. It provides the following benefits:
  • Makes the code neat and maintainable
  • Allows easy splitting of files
  • Eases out the testing and maintenance process

Not using the controller AS Syntax

For assigning a model to the controller object, usually, the developers use $scope. But injecting the scope isn’t the right way to do it. Instead, using the controller As syntax is quite an effective and comparatively simpler method. Also, this syntax can be used in multiple ways in app development. But this syntax also has a drawback, that it provides confusing results while handling various nested scopes.

Unnecessary Use of jQuery

jQuery is commonly used for event-handling, for AJAX operations, and for making DOM manipulation easier. But it is advisable to first use the features available in Angular to the fullest and then use jQuery if required. Developers tend to first prefer jQuery without exploring options in Angular and this may result in unnecessary complications.

Improper Scope Binding

As we know, Angular uses the MVC model. Here, the scope is a set of built-in objects that consists of app data. Scope binds controller and view in the MVC model. At times, developers don’t follow the scoping rules provided by Angular which may result in issues in the app development process. The developers must properly assemble their scope objects.

Not using the Extension- Batarang

Batarang is a highly advantageous Google Chrome extension that aids in development as well as the debugging process. But this extension is often ignored by the developers and not used to its fullest potential.

Putting too many Tasks for the Controllers

In the hurry to meet deadlines, developers may mix logic layers and allocate more tasks to controllers than necessary. This can result in a code that will execute more functions for a certain situation and may end-up in performance issues. For instance- having several event handlers or performing AJAX calls in controllers.

Ignoring Pre-launch testing

Needless to say, it is imperative to do adequate testing before an app is launched in the market. The app should be tested in cross browsers and different environments using tools like BrowserStack or LambdaTest if required. This helps in identifying the bugs if any. These bugs can be worked upon to deliver a successful app. Failing to do so can reduce the success rates to a large extent.

A few more Considerable Mistakes in Angular Development

  • Failing to use the event-handlers properly
  • Not optimizing the Angular app
  • Using the Isolated scope directives more than required which results in several errors.
  • Using more Watchers than needed.
  • Heavy processing that can lead to a frozen browser.
  • Overusing the Resolves that can increase loading times and slow down the app.

Final words:

In an Angular development company, it is quite normal for the developers to make some mistakes while building apps. Sometimes it is due to negligence, sometimes it is due to lack of experience and sometimes it is due to pressing timelines. Even experienced Angular developers tend to make critical mistakes at times during Angular mobile and web app development. But the knowledge of these errors and mistakes in advance can curtail them to a great extent and lead to time-saving and better app performance as well.
