With the present day apps which were known until a few years ago, it has become a necessity more than a choice. So much that you can observe a visible synergy between people’s behavior and with the capabilities of their mobiles. The increasing use of smartphones with portable devices has completely changed the way of communication with enterprise software solutions.

The opportunity level is much higher and you would be able to reach your target audience. Both startups and enterprises are rushing to mobile app development to reach to their segment of users.

According to a report by Statista, in 2021 there were 276.8 million people in the U.S who accessed the internet by using mobile devices. Whereas in 2023, it is expected to reach 287 million mobile internet users. At present more than 83% of the U.S populations are mobile internet users.

Users are spending 90% of their time in Mobile Apps alone.

Both play store and app store are loaded with millions of amazingly featured mobile apps. You can find more than 2.8 million apps in the play store and 2.2 million apps in the App store.

(Source Statista and TUNE)

With the growth of mobile use and app downloads, mobile app revenue has also grown up.

Even in the black Fridays mobile apps are generating revenues, In 2015 – global mobile app revenue was about $70 billion; in 2016 this number reached $88 billion and 2020 the expected mobile app revenue is expected to cross $180+ billion. That’s big.

Let’s have a look

(Source: businessofapps.com/data/app-revenues)

“Mobile apps are becoming the primary way that users across all demographics access and activate content, services, commerce, and critical business applications. This turns up the pressure on organizations to anchor business applications on mobile platforms. It’s clear that enterprises no longer consider mobility the last step toward implementing a business application.”

Peggy Anne Salz, Lead Analyst, MobileGroove

Mobile App must be formulated, well thought over and built to reach a wider customer base and should be friendlier in mobility.

Because users are not always the same and they do not always stick to using the same device and same connection.

Mobility applications with Mobile Enterprise Application Platform (MEAP) development cycle can solve the enterprise level problems.

So now a question might come to your mind –“Is your developer adopting the MEAP rules with mobility technology to develop your enterprise mobile app?”

Here are the basic rules;

Must be compatible with different mobile applications
Must be compatible with different mobile operating systems
Compatible to integrate with different back-end data sources

Enterprise mobile app helps you to be connected and updated with your team or working networks. Data can be accessed anytime through your mobile device and allow your team or employees to access date through their personal devices instead of providing them company smart phone.

Personal devices can safely and easily manage enterprise mobile apps and this is cost effective for companies and not to invest more in smartphones, laptops etc.

So, are you looking to develop enterprise mobile app for your business?

The idea is not bad to go for an enterprise mobile app but you need to adopt the right strategy to get the things done in the right way. You need experienced team or dedicated developers with high level of security for development.

1. Annalise Your Product Or Service Matrices:

Before taking any decision, you need to analyze your user and customer behavior towards your product and how they are responding to it.

You need to deep-dive with your mobile users and if you are a SaaS application development company, analyse how your product is used by various devices, operating system and the usage part, and from where users are churning out.

2. Develop A Baseline Standard

Once you have a mindset for the development after knowing the necessity of an app, you need to prepare a standard baseline against your planning. This will tell you the future of your app development process.

You don’t know what is hot in the market right now and what will be in the next future. So, time to do some research on how the industry is moving.

I am sure; this will surely help you to prepare a standard baseline for your app.

3. Prepare Complete Road-map

Roadmap gives you a clear vision with various steps and processes to reach your goal. Technologies are changing day by day and people prefer to get acquainted with smart features.

Your present app features may not come to picture in next two years or the features might have become obsolete.

This also helps your mobile app developer to make sure plan-out and put algorithms that are flexible enough and can quickly adapt to new features in new devices.

Roadmap can also show you the approximate resources, their skill you need and the development time that would be required at the very said time.

4. Collect Feedback

Gathering feedback from users and your customer about your product, always helps to develop a better app according to the need.

The smart way of gathering feedback is, inviting your existing customer to use your product at each step of your development process. They will love to use it and will let you know there feedback on your product.

5. Start Communication To Build Foundation

Mobile trends are changing each week.

You need to very closely monitor your user’s activity and all your matrices. This creates opportunity for a direct communication with your users. To keep connected them with your app, ask their problems, what their difficulties are, what they are thinking about your app and what new feature will help them to manage their jobs etc., better.

How To Install, Setup And Implement NodeJS In PHP Application

Posted on November 14, 2014 by Jay

What Is NodeJS?

Typically in web response paradigm, the client always initiates communication, but with the help of NodeJS now both the client and server can initiate communication, allowing them to exchange data freely.

In simple words, after a database update the client needs to request the server to get the latest data. But using NodeJS, a client can send the updated data to NodeJS and the NodeJS will distribute the data across all the clients. So, no need to initiate request by each client to the server to get the latest data.

Where We Can Use NodeJS?

Below are the few examples where you can get the best out of Node.js,

A counter which updates after a record insert into database.
Show real-time activity like Twitter or Facebook.
Implement Desktop notification to notify users about what others are doing.
You can build a chatting tool using the non-blocking, event-driven I/O paradigm of NodeJS

Install And Setup NodeJS

Install NodeJS and NPM
Install socket.io using NPM
Install Forever

Run the below notification.js file forever using the “Forever”. (it should not stop)

notification.js

var fs = require('fs');
/* If you are using SSL, uncomment the below lines*/
/*
var options = {
    key: fs.readFileSync('/var/www/html/YOUR_CERTIFICATE_FOLDER/your_project_key.key'),
    cert: fs.readFileSync('/var/www/html/YOUR_CERTIFICATE_FOLDER/your_project_crt.crt'),
    ca: fs.readFileSync('/var/www/html/YOUR_CERTIFICATE_FOLDER/your_project_ca-bundle.ca-bundle')
};
var app = require('https').createServer(options, handler);
*/

var app = require('http').createServer(handler); // For non-ssl server
var io = require('socket.io').listen(app);
app.listen(3002);
function handler (req, res) {
	res.writeHead(200);
	res.end("Welcome to socket.io.");
}
/** This section is for receiving and sending message **/
var Room;
io.sockets.on('connection', function (socket) {
	socket.on('subscribeTo', function (data) {
		if(Room){
			socket.leave(Room);
		}
		Room = data.channel;
		console.log('Connecting client to: '+data.channel);
		socket.join(data.channel);
	});
	socket.on('iotoserver', function (data) {
		console.log('here we are in action event and data is: \n-----------------------------------------------------');
		//var dataJSON = JSON.parse(data);
		//socket.broadcast.emit(dataJSON.channel, { message: 'A new socket added and sending message.' });
		socket.broadcast.to(data.channel).emit('iotoclient', { message: data.message });
		//io.sockets.in('game').emit('message', 'cool game');
		console.log(data);
	});
});

NOTE: Your Node.js should run with the port “3002”. Try to use another sub-domain/domain to call your Node.js server. Another server is always a good option.

Implement NodeJS In Your Application

Use Elephant.io (a socket.io client) to send message to NodeJS.
Get the ElephantIO package from, https://github.com/Wisembly/elephant.io/tree/master/src
You need the Client.php and the AbstractPayload.php file only.

<?php
use ElephantIO\Client as ElephantIOClient;
include("ElephantIO/Client.php");

$elephant = new ElephantIOClient('http://www.your-node-server.com:3002', 'socket.io', 1, false, false, true);
$elephant->setHandshakeTimeout(1000);
$elephant->init();
$elephant->send(
ElephantIOClient::TYPE_EVENT, null, null, json_encode(array('name' => 'iotoserver', 'args' => array('channel' => 'my_first_channel', 'message' => 'my message to all the online users')))
	);
$elephant->close();
?>

Put this JavaScript in the page, where you want to receive the real-time notification

<script src="http://cdnjs.cloudflare.com/ajax/libs/socket.io/0.9.16/socket.io.min.js"></script>
<script>
try{
  var client = io.connect('http://www.your-node-server.com:3002');
  
  client.on('connect',function (data) {
  	client.emit('subscribeTo', { channel: 'my_first_channel' });
  });
  
  client.on('iotoclient', function (data) {
    alert(data.message);
  });
} catch(e){
	console.log('Socket ERROR\n');
	console.log(e);
}
</script>

Rails Or Django – Which One To Choose?

Posted on September 19, 2014 by Srikant M.

Python and Ruby are the most popular dynamic programming languages. Developers are using these two languages for high-level application development. Python and Ruby are popular among web developers because of their rapid development cycle.

Here, I have discussed the most important difference between Python and Ruby:

Philosophy

Python has been designed to emphasize the programmer’s productivity and code readability. The philosophy of Python requires almost everything explicitly defined by a programmer, whereas Ruby allows programmers to reuse the in-built components in development.

The philosophy behind Ruby is that programmers should have the flexibility and privilege to write concise and compact code.

Functional Programming

Both Rails and Django use object-relational mapping to link the application to the underlying database. In Django, the developer is required to explicitly specify each attribute of every class.

But, In rails, all module attributes are not defined in the class definition. A developer can retrieve all the information from the database based on the class name.

In Rails database migrations is very easy and in-built compared to Django, as it uses third party library like South.

Convention over Configuration

Ruby on Rails defines certain features that make web programming more effective and user-friendly. Convention over configuration (CoC) is one of the important features of Rails.

“Convention over Configuration” means a developer only needs to specify unconventional aspects of the application. There are some predefined layout and sensible defaults available in rails projects.

All components such as models, controllers, and static CSS and JavaScript files are located in standard sub-directories and you just need to drop your implementation files into those directories.

CoC saves a lot of time of developers because in rails you don’t need to write the same code again and again.

While in Django, you have to specify the path where the component files are located. So the development cycles in Rails are shorter as compared to it’s counterparts.

Model-View-Controller and REST

Ruby on Rails is unique because it supports the REST protocol. It helps you to organize your application. In Rails, all model objects are accessed and handled in a uniform manner using the standard HTTP verbs like getting, PUT, DELETE, and POST.

CSS, JavaScript and images

Rails have an in-built asset pipeline. Rails’ asset pipeline is having feature of minifying, concatenating and compressing JavaScript and CSS files. Not only that, it also supports other languages such as Coffeescript, Sass and ERB.

Django’s support of assets it very amateurish compared to Rails and leaves everything to the developer. Django offers static files, which basically collects all static files from each application to a single location.

URL mapping

Both Rails and Django allow for the use of regular expressions to customize the mapping of URLs to controller actions. Both are flexible enough to allow you to create pretty much any mapping scheme you wish.
But, Rails does automatic URL mapping based on the class and function names within controllers by default.

Testing

Testing is very easy in Rails and there’s a much stronger emphasis on it in Rails than in Django.

Popularity

Python is generally more widely used than Ruby. Due to the rising popularity of the Ruby on Rails Web application development framework, Ruby’s popularity to has seen rapid growth.

Both Rails and Django are effective web frameworks powered by efficient programming languages. However, Rails is the best platform for rapid web app development.

Andolasoft offers quality rails development service. We specialize in developing database-driven web applications in an efficient and hassle-free way.
