Coronating iOS Development with MVC vs. MVP vs. MVVM vs. Viper

We are going to explore three Node.js backend frameworks: Express.js, Koa.js, and Sails.js.

These are MVC server frameworks and written in JavaScript.

Therefore, they share the same advantage - they are compatible across various browsers, devices, and OSs.

To learn about their differences, lets delve into definitions a bit.What are MVC frameworks for Node.js?The frameworks that emulate MVC pattern for Node.js framework are also known as Node MVC frameworks.

As the name implies Model View Controller approach is based on three components: model (which is business logic and data of the app), view (format and layout of data - app UI) and controller (which sends requests and updates between the two).How MVC approach worksFrameworks that are based on MVC approach are generally good for enterprise-grade solutions and provide upfront support while being not so much flexible.

For more simple solutions, a more lightweight Node.js server framework is a better option as they let apps be maintainable with less code while building and in many cases are based on middleware.How middleware affects Node.js web development?Middleware is a piece of software that glues and controls the flow of information between an application and the server, database, and operating system.What is Middleware?When you build Node.js apps, you can create a middleware of two types:Intermediaries: the elements that process the requests and responses, but they are not fully responsible for the request itself, so they delegate the request to the next layer.End elements: elements that are fully responsible for the final response.

Differences between Android and iOS :

User Experience : iOS is rated superior than Android on the basis of user friction and cognitive load. iOS 7 rates itself as 73.25% and iOS 6 as 70%, and Android (Samsung) is rated as 57.25%.

Apps Available : The app store for Android covers Google Play- 1,000,000+ apps. The other app stores such as Amazon and Getjar to share the Android apps. Whereas the app store for iOS includes Apple app store- 1,000,000+ apps.

Software Upgrades : Though Google keeps updating Android often, but few users fail to obtain the updates on their smartphones or might have to buy phones with out-of-date software. Whereas iOS upgrades are accessible to every iOS device.

There was a period when cybercriminals usually focused on desktop computers and laptop for attacking.

Apple never releases its source code to app developers.

These devices owners can move around with their device’s operating systems.

They prompt the users to install them as soon as they are released.

Staying Safe on iOS and Android

Android is alluring because it provides an operating system that is more open.

JavaScript is a gamechanger for building customized, enterprise-grade web and app solutions.

As a robust JavaScript framework, AngularJS offers more flexibility and scalability for developing dynamic web apps.

The search engine giant Google maintains this open-source, front-end framework.

When you want an optimum ROI on the cost of app development, AngularJS should be your choice.

For example, the recent version Angular 9 resolves issues of Angular 8.

It facilitates Angular developers to ship less code as compared to other similar frameworks.

Both Android and iOS, the two most popular mobile platforms, biggest battle going on in today’s digital world.

For those who haven’t made a decision, which mobile OS would you opt for, which mobile OS just suits you best?

Sometimes Android users had to wait a long time and iOS had more than 700,000 apps on the App Store were available to them.

Push notifications are an essential part of mobile apps that if used properly can be a great channel for consumer interaction and engagement but there are also times when overenthusiastic businesses turn them into a source of annoyance for users.

The complex technologies and processes underlying those notifications?

GCM is a Google Play service used by a majority of applications for serving push notifications to Android devices.

For instance, if the users open the notification on one device, it would disappear from all of their devices.

The Android device sends a sender ID and application ID to GCS server

After registering the device, it issues a registration ID to the device

iPhone preferred position is available in Android regarding programming refreshes. Updates on Android are moderate while in Apple the updates are quick.

Apple iPhone Wins Over Android

If your answer to these questions are yes, then you should definitely consider becoming a Salesforce developer.In my previous blogs, I have discussed Salesforce, Salesforce certifications and also shown you to build a custom application using the declarative options available in Salesforce.

Below is a diagram that outlines the Salesforce Model-View-Controller architecture along with the different Salesforce components.Model: The model is your Salesforce training data objects, fields, and relationships.

Few examples of situations where you can use Visualforce are:To build email templatesTo develop mobile user-interfaceTo generate PDF’s of data stored in SalesforceTo embed them into your standard page layoutsTo override a standard Salesforce pageTo develop custom tabs for your applicationA visualforce page consists of two primary elements:Visualforce Markup – The visualforce markup includes the visualforce tags, HTML, JavaScript or any other web-enabled code.A Visualforce Controller – The visualforce controller contains the instructions that specify what happens when a user interacts with a component.

The visualforce controller is written using Apex programming language.You can take a look at a simple Visualforce page code along with the different components below:Below I have shown you the steps to write a simple visualforce page for displaying countries and their currency values:Step 1: From Setup, enter Visualforce Pages in Quick Find box, then select Visualforce Pages and click New.Step 2: In the editor add the following code to display country and its currency value: ApexOnce you are done developing the user-interface, as a Salesforce developer you need to know how to add custom logic to your application.

Few examples of situations where you can use Apex are:When you want to add web and email services to your applicationWhen you want to perform complex business processesWhen you want to add complex validation rules to your applicationWhen you want to add a custom logic on operations like saving a recordBelow is a screenshot of Apex code along with its different components like looping statement, control-flow statement and SOQL query:iculumNow that we have understood what Apex is and when to use it, let me dive deep into Apex programming.Programming In ApexIf you have understood the concepts described above, then you are halfway through your journey in becoming a Salesforce developer.

If you want to be a Salesforce developer, then you must know both of these query languages.

Sailfish, a new mobile operating system is posing grave challenge to the monopoly of Android and iOS.

The OS developed by a group of engineers from Nokia have introduced their platform into the new Jolla phones.

Sailfish is primarily a gesture based mobile platform based on the Nokia’s Meego, a Linux-based free mobile operating system project, which didn’t take off.

Instead, it’s being created on the top of Sailfish OS, which was developed by a Hong Kong-based start-up Jolla — a company formed by former Nokia employees.

Sailfish OS is based on open source Linux kernel and features Jolla’s open source Mer Core UI and other third party components.

Unlike the Nokia Lumia series phones the Smartphone is capable of changing the color scheme, wallpaper and fonts according to the back cover changes.

Angular JS is a powerful open-source framework which can help in dealing with the challenges and difficulties commonly associated with web development processes.

It can help developers to easily integrate application modules and HTML codes when they are working on a project.

It is due to factors such as these that every AngularJS development company strongly recommends their clients to have their projects developed with AngularJS.

You can also have greater accuracy and flexibility with the coding process once you start using Angular JS.

Allows Developers to Reuse the Code

When you go for Angular JS, you actually case reuse the codes as well as the code components that were written before for other applications.

Along with its list of flexible features, it provides the ability to merchants to accept payments online or within a mobile application.

No matter which type of business you run, it is easily integrated with your application.

With Braintree, we can use client (we can pay money) and server (we can receive money) in our applications.

It supports different languages like PHP, Ruby, Python, Java, Dot Net and also compatible with platforms like Android, iOS, and Windows.

It accepts all types of card from different providers like PayPal, Venmo, Bitcoin, American express etc.

It has lots of features like recurring billing, international payment support, credit card storage, PCI compliance solutions, easy dashboard and lots more.
