Benefits of Using Node.js for Web Application Development

Node.js for Web Application Development

A brief history….

Ryan Dahl is the creator of Node.js; He thought of this language after facing glitches in file upload progress bar on Flicker. The Browser lacked the capability to know how many files had been uploaded. During that time, Apache HTTP Server was unable to handle concurrent connections (up to 10,000 and more) and with sequential programming, the code either blocked the entire process or resulted in multiple execution stacks in case of simultaneous connections. Thus, he looked for the easy ways to get the things done faster. Node.js came into existence and major perks included were – reduced time-to-market, dynamic Node.js web applications, high agility, support for the development of highly functional mobile apps to name a few.

About Node.js

Node.js is an open-source cross-platform built on Google’s V8 JavaScript engine. It executes JavaScript code on server-side at run-time and is best for building fast and scalable network applications. It is light-weight, competent and perfect for data-intensive real-time applications that run across distributed devices. Moreover, it contains built-in library that allows applications to act as a Web server without software such as Apache HTTP Server.

Benefits of using Node.js for Web Application Development

  • One language on both front-end and back-end

One of the most critical issue in the web app development is the use of multiple languages and environments on both back-end and front-end.  Node.js which is written in JavaScript eliminates the need for using multiple languages. You can leverage the power of JavaScript by using your preferred and same programming language in your front-end and back-end framework such as React, Ember, and Angular etc. to create the best web 2.0 applications.  If you’re using the same language in front-end and back-end, you will need fewer resources and that can cut-off your much overhead cost.

  • Event-driven, non-blocking I/O model to perform fast operations

Node.js uses asynchronous architecture to perform I/O operations which is the best for handling the large volume of requests from web and other networks. Before Node.js, I/O operations were performed synchronously or were multi-threaded which means threads can be blocked while waiting for the replies from the database and also consumed much of the memory. But, with Node.js, applications can perform an asynchronous task to the event loop (a single threaded loop), along with the call back function and then continue to execute the rest of the program. After completing asynchronous operations, event loop returns to the task to execute call back. Moreover, Reading/writing to the network connection, reading/writing to the filesystem, and reading /writing to the database is executed very fast.

  • Node Package Manager to increase code reusability

As Node.js is an open source technology, it has the code repository of the best tools and modules that developers can use within their project. By default, it comes with every Node.js installation and includes more than 350,000 packages for creating effective web solutions. Using these packages, it becomes easy for the Node.js developers to easily update, share and reuse important codes without much effort. Moreover, it is also easy to work on the core applications without knowing what’s around it and built-in modules will take care of the rest. Anyone can take advantage of module ecosystem and can even publish their module which will be listed in npm repository.

  • Data Streaming

Node.js possess the capabilities of data streaming which transfers a large amount of data such as audio files, videos, photographs etc. by breaking the data into manageable chunks. This chunk of data occupies less memory; so, they are less likely to slow down the device. This saves much of the time and enables the user to carry out different operations.

  • Real-time applications

Node.js possesses an event-driven architecture which accepts large requests by using minimal resources and time; hence, it is ideal for developing real-time application especially chat apps, games and headless browsers like chat bots, Alexa etc.  It has some plug-ins that implements a web-socket protocol. This enables two-way communication channels between client and server which means a server can push data as easily as a client can. Hence, the performance of the applications doesn’t degrade even if there is a sudden surge in the traffic. Generally, real-time apps are equipped with high-volume of data continuously and chances of getting app crashed are almost high. But Node.js refrains your app getting crashed.

Brands are already using it

PayPal: Initially, PayPal was using Java on server side and JavaScript on the browser side. They thought of experimenting by developing a prototype on Node.js and java too. For developing a prototype in Java, they assigned 5 developers and 2 developers were assigned for Node.js. Unpredictably they got great results in Node.js with the team of 2 developers in prototype development.  After running the test cases with the same functionalities of Node.js and java; it was found that,

  • Node.js can be written in 33% fewer lines of codes.
  • It is very fast and takes half of the time to develop an application compared to java

35% decrease in the average response time for the same page. This resulted in the pages being served 200ms faster”

The reason they wanted to use Node.js was to handle 100% business availability even with the huge load.

Uber

Uber – a peer-to-peer ride sharing and taxi services platform always wished for a transportation that is reliable as running water, everywhere for everyone.  According to Uber, “Node.js is the best for writing system that has all their state in memory”.

They found 3 core strengths in Node.js i.e:

  • It handles asynchronous I/O requests with a non-blocking, single-threaded event loop so it is hassle-free for Uber to handle a volume of information quickly.
  • As Node.js is the best for quick iteration, developers can use new codes instantly and errors can be addressed easily without requiring a restart.
  • It gets better all time as its open source community is constantly optimizing the technology.

Taking into account these considerations, Node.js has set the standards for web app development and is definitely the go-to technology for start-ups and enterprises. If you are looking to develop next enterprise app; then Node.js is definitely worth a try.

Emerging Technologies: The Future of Real Estate Industry

Real Estate

“There is no substitute for innovation. Original and Revolutionary idea will always rise on top”- Richard Branson

Looking at the current scenario, real estate business is cluttered with too much of services under one roof with no transaction transparency and uniqueness. When searching for a property, potential buyers have to meet the realtors, view property and at last, discuss about pricing. Moreover, the chances of fraud are always at its peak.

How can we overcome these challenges?

With the increased mobile penetration in the daily lives of people, businesses can operate from anywhere. Mobile apps  as well as web apps enables real estate business to view and showcase the property on the smart device and also provides easy access to check space details, appointments, reports, tracking of leads etc.

Adapting the emerging technologies is becoming imperative and helps the real estate industry to hit the mark. Let’s run down through the emerging technologies that can help realtors.

Chatbots

As the digital world is growing, customers expect impromptu interaction with the right information at a regular interval of time. Realtors may struggle to meet this need! But thanks to the Chatbot, they can provide right information anytime. Customers generally turn to internet for buying and selling houses but feel reluctant to fill the registration form. However, they may be ready to talk with the person who is sitting at the backend (chat bots). Chat bots interacts with the customer by making use of internal and external databases to offer personalized interactions and provide specific data to each prospect; resulting into higher lead conversions.  By automating the initial conversations between agents and prospects, Chabot can surely be an effective and efficient tool in engaging visitors and higher lead conversions. If used in a right way, they can be a key part of realtor’s marketing approach lead conversion.

Blockchain Technology

Blockchain has the ability to transform real estate industry through recording and combining transactions into decentralized secure ledger system. It creates block of transactions that are linked and secured using cryptography that no party has control of. In present situation, the transactions in real estate sector are non-transparent and take place through brokers, lawyers, and inspectors and so on. This involves high risk. To avoid this, Blockchain technology can be used where anyone can record information, without being censored or without needing any permission. Moreover, Blockchain technology cuts off third party cost; to prove authenticity, the seller can legitimately transfer the ownership to the buyer without having to pay for third-party verification. This technology can also be helpful in creating smart contracts, where seller can get away from slow loan process by creating a digital id. And by doing so, transfer of ownership would become seamless and much quicker. These smart contracts are permanently stored on Blockchain and become irreversible and unalterable.

Artificial Intelligence

Artificial intelligence can be used in predictive analysis where, real estate investors can set the growth goals and have them monitored with AI tools which can predict risk based on investor parameters and make adjustments to reach financial goals. AI plays a main role in property management where it can predict when maintenance system expires or are ready for replacement. AI can help buyers in decision making; when machine tells you that, “property you are browsing is a good deal”, it’s because AI algorithms have calculated that answer based on the data that was made available. When a human real estate agent tells you it’s a good deal, it may be because of their instinct or because they may be interested in getting more profit or selling property faster.

Virtual Reality

Before deciding which property to buy, client has to visit multiple properties to find the best one and this consumes more time and money. Moreover, if client is staying miles far, it is not always a feasible option to visit each property. But, Virtual Reality can solve this problem enabling millions of people to visit the property without leaving their homes. Real Estate agent can use VR headset to get three-dimensional walkthrough property and immersive experience of the property. If client has to check multiple properties, in matter of minutes they can virtually check out a good number of locations and decide which is worth buying. Another reason of using VR technology is, it helps the realtors to market staged properties with little investments.

For instance, Company named Roomy offer VR staging services to the real estate agents. It enables to create 3D real estate tours and get property staged so that their clients can check that out easily.

Conclusion

Today, emerging technology has become more reliable, integrated and robust and using this technology is not an option today. In order to stand out from the crowd, using technology in real estate can increase leads and surely takes your business to the next level. With the advancement in these emerging technologies, real estate companies need to stay abreast with the current trends in technology world.

Whether, you are an owner, property manager or real estate company, TOPS Infosolutions provides exceptional software solutions for streamlining real estate services. Our responsive mobile app portals and web app development have helped real estate client across the globe to generate more leads and increase ROI.

Tech Pack: Simplify Your Fashion and Apparel Production

Tech Pack

As fast-fashion has become a specific norm in the industry, it is difficult to get your products to the market quickly– quicker than the competition. However, in the global fashion market, getting all the things done on time is mere nightmare. Everyday professionals have to deal with time and commitments to get the tasks done; however some retailers can manage complex tech pack process through the spreadsheet alone (once a garment is designed, it’s specification are stored in several spreadsheets, design documents by creating a large folder of the one garment which is then emailed to the supplier) which leads to the risk of human error. From technical designers – product developers – production manager to the suppliers where no one is in the loop ends up with simple design flaws becoming a big problems on both the technical and fiscal end.

The problematic questions that are likely to be raised are:-

  • What sort of documentation should be crafted?
  • How to communicate with all suppliers?
  • What would you give to the pattern maker?
  • What is returned to you? How much time it will take?

The trials and tribulations are plenty!!! Finding the right factory and communicating properly with them to make the right product is not something that you can just wing.

Factors that prevent efficient operations in tech pack without system

  • Lack of centralized data: Manual processes are prone to human error and data is not centralized or standardized. Hence document proof is difficult to achieve
  • Version Control: Completed design passes through various milestones before the master piece is created. Managing this in spread-sheet complicates the entire process.
  • Compliance issues: Garment designs comprises of different colors, sizes and dimensional characteristics, which means that the margin for error is especially high – particularly if all these issues are accounted separately, instead of in one single place.
  • Encumbered collaboration: When external departments and team members (e.g. manufacturers or suppliers) can’t effectively collaborate within a central system to share ideas and insight, creativity and innovation are impeded.

Hence, there comes the need of streamlined system with high integration of multiple business processes and accessibility of information at any given time.

So, how streamlined system can help you to develop smart tech pack?

It simplifies collaboration and communication between product professionals, enabling them to effectively manage data throughout the product development. It helps developers, designers and manufacturers to stay on same page following the same schedule and interacting in real time. For instance: Fashion professional wants to create sheath-velvet dress; with this solution, everyone involved from design to manufacturing remains in the loop without necessary being on the same location and can easily access the tech pack of sheath-velvet dress to determine who is doing what, which is the next phase of the project etc.

What does it bring to the table?

A lot actually. As it enables the team to work on the same page; it makes planning easier, stay updated with the recent version of the product and find out if the product is dropped from line. More time is saved as there is no need of paper work and manual work or e-mailing every supplier from time to time.

Basically tech pack consists of

  • Drawing
  • Measurement
  • Description of fabric
  • Trim Design
  • Grading
  • Prints
  • Label
  • BOM

With tech pack on your screen, you can check out what the product’s agenda is and what modifications are to be made to the product. The ability to manage multiple aspects greatly reduces errors and you can review your product in less time compared to the traditional product management. So, with the streamlined system everyone associated with the product can stay in the loop and works as de-facto between manufacturer and client

The benefits can be categorized as

#1 Shorter time to market: On having centralized control over the data, it is likely that product development can be completed more quickly. Product designer and the team associated with it can work faster and data transfer is also hassle-free. Faster development and shorter time to market are always quintessential to remain competitive.

#2 Increase productivity: Implementing autonomous system nullifies time-consuming activities like duplicity of data across different system, multiple times checking of data for any irregularities, search for missing data etc. Product design team who already have integrated this system are less likely to come across processing errors and the reworks due to outdated information.

#3 Enhances product quality: As managing and controlling all the information is easy; it likely affects the overall product quality. By using the system, product managers, suppliers and associated team are able to implement all the processes which help to maintain product quality and that result into customer satisfaction. This is important, if the team is spread across different demographics to ensure that quality is not compromised.

#4 Connects design with data: Suppliers can upload new design concepts directly into the system and can quickly bring those concepts to the life by using the advanced tools. By connecting creative design ideas to the system, you can increase accuracy and reduce waste.

#5 Enriches user-experience: If you have an automated system, you will able to work smarter and faster than ever before with simple drag and drop functionalities. This would even require less training and speeds up adoption.

Helpful tips to look for…..

  • Don’t make your information messy; spread the details so that everything is easy to read. Cluttered things won’t able to keep your instructions simple, clear and direct.
  • Add images to make it clear and detailed.
  • There are the chances that trim designers may not read the tech pack so it is recommended if you can provide sample of the garment so that they can know how the final product should look.
  • When you design a tech pack make sure there is no typo error, incorrect measurements or fabric type which results into delays or other problems.
  • Create a PDF of your tech pack so that it helps to protect and prevent others from editing it
  • Think of creating PLM system which helps to manage entire life cycle of the product from inception, through engineering design and manufacture to service and disposal.

The bottom line…

Keeping consistent tech pack from the scratch to the development process will save your time and many head-aches in the long run. The system for tech pack that we craft is crystal clear and planned by industry experts. We assure you that your production runs will be smooth and cost-effective. We do all the heavy-lifting so that you can focus on your brand.

Artificial Intelligence (AI) and the Future of Web Development

Artificial Intelligence

“A year spent in Artificial Intelligence is enough to make one believe in God – Alan Perlis”

Internet has evolved a lot since its birth and it has made the web development evolve as well – website building was a very easy process that involved nothing more than pages of standard texts with few pictures and font variation. Fast forward a decade; society was gifted with standard web connections which enabled website to develop on HTML and PHP, included graphics and animated design elements. Fast forward another two decades – today with the advancement of technologies, web development consist of mix of images and audio visual content designed to deliver the best user-experience rather than just information.

As per the recent news, humanoid robot Sophia has been made a citizen of Saudi Arabia. Was that something ever expected? Additionally, Gartner predicts, “By 2020, customers will manage 85% of their relationship with the enterprise without interacting with a human”.

So, here the question arises, with whom will they interact? The answer is quite simple – via Artificial Intelligence (AI); i.e. simulation of human intelligence processes by machines that includes learning, reasoning and self-correction. For instance: Siri, Cortana, Chat-bots, self-driving cars etc are delivering optimal user-experience with the help of AI.

Today, as web-development focuses on enhancing user-experience; small, medium as well as large enterprises are looking forward to leverage the power of Artificial Intelligence for providing personalization and boost their web-experience.

Why it is important?

  • Automates repetitive learning and discovery through deeper data
  • Adds intelligence
  • Adapts progressive learning algorithm
  • Achieves incredible accuracy

Let’s check-out how Artificial Intelligence is changing the scenario of web-development:

  • Better Predictive Reply

A predictive reply is the process of interaction between user and machines. Machine fails to understand the human’s emotion but Artificial Intelligence can understand the same and responds accordingly. This helps in getting quick answers, making it easy for the customers and business to resolve their queries. Recently, Google updated the Gmail app with an AI-driven “Smart Reply” feature that predicts responses you may want to send. The feature uses machine learning algorithm to analyze your emails and suggest quick, bite-sized responses you may want to send. What it does is, it tries to understand the email message and predicts what preferable responses you can give. Chatbots powered by AI, interacts with the user in a natural way leaving no scope of misunderstanding and enriching user-experience. To be precise, you can create websites or web-enabled devices that can communicate like a human in an effective manner.

  • Voice-based search

Voice-based search empowered with Artificial Intelligence is the key-driver in enabling seamless voice conversation between users and website. Siri, Cortana, Alexa can do virtually anything from assisting you to set the alarms, schedule meetings, controlling and checking the status of smart-home devices, make and receive phone calls, get directions etc. As the user interacts with the virtual assistant, they can learn about your voice, intent, preferences and much more as the AI backend code uses the sophisticated algorithm to learn from the data input; predicting the user’s need in a better way. And by doing this, it learns how to work with you better as well as serve you in an enhanced way. Virtual assistance can be an integral part for all e-commerce web players to enhance web-experience and shopping in a smarter way. Digital Assistance also maintains privacy policies, which defines how each company uses and share personal information.

  • Machine learning

Machine learning technology – the element of Artificial Intelligence has come along a broader way to provide customization in websites and personalization to the users. It predicts the user’s intention by analyzing previous activities and accordingly adjusts messages based on the interactions and behaviors. Machine learning make use of algorithms to make computers learn without being explicitly programmed. Through machine learning the application analyze data that helps to automate the analytical model building, enabling the systems to find hidden insights. It applies complex mathematical calculations to the big data – over and over, faster and faster to predict the future problem and preventing them from occurring.

Some popular scenarios of machine learning used in web application are:-

-Online recommendation offers from Amazon, eBay etc

-Spam detection in form submissions

-Search engines

  • Boosts the content-quality

It is easily said ‘Trigger the right message to the right buyer’, but doing it is altogether a different challenge. In this digital era, which is the best way to present the relevant content to every person who engages with your brand? The precise answer is, through Artificial Intelligence. It helps the web-marketers to create the relevant content for their audience at every phase of marketing funnel. With the help of algorithms, robust analysis and scrutinizing the data of competitors, it is easier to gather information about target audience which includes what their likes and preferences. With such insights, you can curate your content and provide relevant answers to boost customer engagement and rank high on conversions.

  • Provides unique store experience

Retailers use Artificial Intelligence to analyze the customer data in order to gain insights about customer’s behavior. It provides the personalized approach to each customer by offering shopping recommendations, deals, discounts and much more. Chat-bots, an extremely multi-faceted tool, is able to detect the tone of the user’s message and determines the best way of responding. AI enables online retailers to boost sales and forecast demand, to gain a better understanding of consumer behavior.

Wrapping it up

Artificial Intelligence is an advanced and decisive technology which adds value to the user experience and organizations. In the coming years, AI will play a crucial role in bringing the web and user close to each other.

LAMP vs. MEAN Stack: Choosing the Right Fit for your Project

MEAN vs. LAMP

E-commerce platforms like Amazon, Walmart, eBay, Alibaba etc. provides the best user-experience and that’s the reason they are always on the top of trends and can respond to the millions of request within seconds. It is all because they have used the best business model which is supported by influential technology. Have you ever thought how huge such kind of system would be? What it would take to reach such great heights?

Let’s figure it out…

To develop such web-driven application, it should be supported by the technology like Apache Tomcat as the web server and PHP and J2EE as development framework. Since years, LAMP is serving as go-to technology as it is involved in Linux, Apache, MySQL and PHP, Perl or Python. Although LAMP being good technology to deal with, it is a conventional approach to handle large database web-applications. So, this technology is replaced with MEAN (MongoDB, ExpressJS, AngularJS and NodeJS) to provide faster and efficient web development due to the JavaScript compatibility. Since it works on the REST API, web-app can be developed by multiple front-end and the same back-end; hence reduces the cost of developing back-end. Moreover, you can replace Angular.js with any framework that suits best for the system.

Why MEAN is the best for your enterprise compared to LAMP?

  • MongoDB vs. MySQL:

MongoDB is considered as modern NoSQL database with number of features and compatibilities. The strength of MongoDB lies in relational database compared to MySQL. When relational database is used in MySQL, it feels like data is pushed into the table forcefully. The system works perfect when single entry fits into every single format, but fails badly when it doesn’t happen. On the other hand, MongoDB offers a document structure which is more flexible. So, if you wish to add new fields then simply add the field to the form, roll it up with the rest of Data in JSON document, and put it into MongoDB collection. This is great for the data dealing with dynamic data which is difficult to constrain in table form.

  • Makes your UX better with front-end

One of the major reasons to shift from LAMP to MEAN is to migrate from server-side page generation to client-side single page applications. In MEAN, Express.js works on the REST structure and handles server-side routing and Angular.js handles client-side views. The web-page presentation and control flow task in LAMP which was handled by PHP, Perl or Python is taken care of by Expres.js and Angular in MEAN. Additionally, Angular.js also handles data presentation of an application. Hence, this shift is from synchronous to asynchronous processes and page-centric views to component-oriented views of an application. Moreover, being backed with the excellent JavaScript front-end framework, web-app runs efficiently, making the UX smoother. With all such parameters in the mean stack, it enables the web application to run on desktops, laptops, mobile phones, tablets etc.

  • The Code

MEAN makes the use of Express.js and Angular.js to drive the web page presentation and control flow. Express.js serves as a controller layer, controlling application flow and organizing data for Angular.js, which handles data presentation. The importance of this is, it has simplified back-end architecture. If you write the code for Node and decide to place in Angular, you can do it with ease. This flexibility makes the MEAN based apps significantly easier. You can have the added benefit of having entirely single language and don’t have to look for the additional developers like PHP expert, JavaScript expert or front-end or back-end specialist – just a front-end java script developer to trace all the way down the stack without having learn other programming language.

  • Node.js simplifies the server layer

Navigating various layers of LAMP stack is like dancing on many hats; going through the various config files with different syntax.  This sounds bit clumsy. But, when it comes to MEAN, it simplifies this with the help of Node.js.

Sprinkle in some JavaScript whether you want to change how your app routes requests or want to change the logic used to answer queries or if you want to rewrite URLs or construct an odd mapping and let Node.js do the rest of the work. The MEAN stack in combination with Node.js keeps everything in one place and one language. You don’t have to read the pages of PHP, generate different config files etc as in LAMP. Having everything at one place reduces the chances of errors and confusions between multiple layers.

To be precise…..

LAMP stack has surely become a conventional approach but it holds the good efficiency in the market over the years as many CMS still rely on LAMP. However, MEAN Stack becoming new player provides the new and innovative ways to cut the grounds. MEAN web development has its own list of benefits to offer for a flexible web development especially for an organization that is looking to move its focus from LAMP to an advanced Mean stack technology.

Building Modern and Scalable Enterprise Apps with MEAN Stack

MEAN Stack development

Today, web programming being one of the challenging tasks, especially in case of enterprise applications, business owners look for the technology that provides high performance and scalability. Many enterprise leaders struggle to stand tall amongst competitors – so to deal with such requirements; web development companies have to deal with the host of technologies dealing with security, networking, databases and development of server-side and client-side components. Although there do exists much powerful communities that provide solutions for the enterprise applications but the one that enables the modern web development is the full stack solution – MEAN Stack.

MEAN – the full-form for MongoDB, Express.js, AngularJS and Node.js which was possibly the much needed and awaited revolution for the technical sphere. This stack is crafted by diverse teams and considerable community of developers is also involved that pushes forward the development and documentation of each component. And now that MEAN Stack is so much into the world of technology and business, every growing enterprise is striving to become MEAN friendly; leaving behind plenty of solutions who are still showcasing their loyalties towards older versions! The core thing in this stack is the centralization of JavaScript as the primary programming language.

  • MEAN makes switching between client and server easier

MEAN is simple & fast and developing the apps in this technology enables the developers to write the code only in one language i.e. JavaScript for client as well as server side. Entire project can be managed by MEAN Stack formula and Node.js developer can deploy the applications on the server directly without the need of deploying it to a stand-alone server. Additionally, it is OS independent – be it Windows, Linux or MAC. This is the best for startups and enterprises as they just have to accommodate development framework and need not think on technology. No need to waste time in scanning libraries as all JavaScript libraries can be combined with MEAN stack. The saved time can be utilized for other productive activities which are especially crucial in the case of Startups.

  • Facilitates speedy data storage and retrieval

MongoDB in MEAN Stack uses JSON like documents throughout the database which makes it a documented database. The document structure offered by MongoDB is extremely flexible. No hardcore restriction to forcefully enter data into tables to make it usable. For instance: addition and deletion of data can be easily done without making any complex accommodations.  MongoDB doesn’t require any predefined database schemas and rules to establish field relations like MySQL. Hence, when no large schemas are present, the system becomes efficient and fast to use and ultimately benefits the end user increasing their confidence in the start-up offering their services.

  • Uniform code from start till end

With the sufficient knowledge of JavaScript developers, you can manage your entire project with ease. JSON like queries are already available in MongoDB database, hence JSON queries can be used with Express.js and Node.js server and can have similar format for all data transfer. However, some angular queries can be used on client side using Angular.js. Furthermore, usage of express.js and angular.js on the top of node.js results into technology stack that gives the benefit of single language means the full stack developer can manage the stack easily without learning another programming language like Python or PHP. The experts in JavaScript can go through the entire MEAN stack themselves and can control both front-end and back-end activities. This is quintessential because developers couldn’t code, if they don’t have core knowledge of all respective technology. Other than that, page load time can be substantially reduced with node.js framework.

  • MEAN stack supports MVC architecture

When it comes to MVC, there are four aspects that help the developers for easy execution; namely – database, server, client and client UI. In MVC, the model responds to the request for any information or data manipulation according to the controller’s instruction. The controller on the other hand responds to the system that user needs and thus gives instructions to model. To run MVC framework complex procedures, there are numerous stack frameworks on innumerable different programming languages. With one programming language and flexible database, MEAN stack is considered as influential alternative which can compile with MVC architecture very easily. This enhances the productivity of developers and enables the application to load faster and also assures quicker project completions.

  • Regular component updates

MEAN stack components are open source, free to use and their respective communities and support channels do come up with frequent releases and updates. More ideas and insights from the developer community and tutorials on how to overcome hurdles to emerging challenges help keep the products and services relevant to today’s economic of scale. The overall framework is flexible and easy to understand by making it popular with enterprises and developers.

In a nutshell, many business owners make the use of MEAN stack to revamp their existing websites. It is also ideal for other web content like blogs, media websites, data-intensive and real-time messaging applications. If you wish to develop you next big project in MEAN, our skilled consultants will help you craft the perfect business plan. Having hands-on knowledge, our team will quickly transform your idea into world class application.

Top Features to Look For in Angular 4.0

Angular 4.0

When Angular 2.0 was released in September 2016, it signaled a remarkable move in enterprise front-end development. Angular.js was completely revamped with Typescript which is Microsoft’s strongly typed super-set of JavaScript. With such paradigm shift, type-safe languages such as Java, C# and Scala were welcomed into the world of modern front-end development. And now Angular 4.0 has been rolled out with the features of semantic versioning.

In order to remain on the toes with the user expectation and deliver the latest features in a mobile app, it is necessary to keep updating the technology with the latest frameworks. Angular 4 is one such framework and core focus of this update is all about reducing the size of the code generated and to keep framework aligned with the release time. They skipped out version 3 and directly shifted to version 4 in order to sync up the Angular router’s version 3.x.

The Angular 4.0 holds SEMVER i.e. Semantic Versioning which means unbelievable improvements that should be explored by mobile app developers to see if it can handle the development process uniquely. This kind of release is classified into major, minor or patch release based on the nature of software release.  The software version will get bumped up accordingly.

A semantic version possesses following three numbers:-

  • 3 – MAJOR: When they released a breaking change, they increase the first number of semantic versioning. It is increased when there is an incompatible change to the API. This is possible for Angular, if newer versions of the utilized library gets adopted to bring modifications in the API
  • 2 – MINOR: When new functionality is supplemented to the existing functions and API is kept stable; there is an increase in the second number of semantic versioning.
  • 1 – PATCH: When any bug is fixed without altering the API, there is decrease in the last number of semantic versioning; thus being backward incompatible.

Additionally, there is an optional – QUALIFIER specifying a version in a more accurate way.

What’s new in Angular 4.0?

  • Instead of TypeScript 1.8+, Angular v4 now requires TypeScript 2.1+
  • OpaqueToken, SimplyChange etc. are some of the interfaces which are either changed or removed completely
  • Every latest feature in TypeScript 2.1+ are now supported by Angular 4

Typescript and the benefits of strongly typed languages

Angular 2 enabled developers to allocate types, interfaces, classes and inheritance to their front-end code. When a Static type was introduced, it ensured that any error conducted by the developers can be immediately caught by TypeScript compiler and the code written are easy to understand and simple to consume.

Features of Angular 4.0:

  • Long-term support (LTS)

At NG-Conf 2017, the team of Angular announced that version 4 is the initial version of Angular which provides Long term support. This means it is benefited for those enterprises that don’t have facility to constantly upgrade Angular entities.

  • Faster Rendering and Smaller Bundle Sizes with AOT Compilation

Ahead-of-Time (AOT) being one of the greatest features of Angular 4 is capable of compiling templates during build time in order to generate JavaScript code. With AOT you can:-

-Detect template errors at the build time instead of runtime, making application quick start

-As the package size is smaller, there is no need to ship Angular compiler to the user

View Engine: This is capable of producing less code, when AOT compilation mode is used. Hence, the reduced code is generated for your components – 60% in most of the cases. More complex the template, higher the chance of savings.

Animation Package: Angular 4.0 have pulled the animations out of @angular/core and into their own package. This means that extra code will not end up into production bundles, if you do not use animation.

  • Better error messages

With Angular 2, cryptic set of error message was somewhat the source of frustration. With the introduction of Angular 4.0, error messages are much clearer and informative. All thanks to new template source maps, they point directly to the lines of code within templates.

  • TypeScript 2.3

Anglular 4 uses the latest version of TypeScript than Angular 2 which enables better type checking and also enables faster compilation time.

  • ParamMap Router

Until now, route parameters was available by standard JavaScript syntax (parameterObjekt[‘parameter-name’]) and was stored as a simple object structure. But, with Angular version 4, parameters are also accessible as map and can be available with the method called (parameterMap.get(‘parameter-name’)).This is because, it has some benefit in terms of security and traditional structure seemed unsafe (type Params = {[key: string]: any}) as parameters could take any possible values. But, with this new map, parameter value is either a string or an array of strings, depending on the method used.

  • Server-side Rendering with Angular Universal

Google’s server-side rendering library called Angular Universal is compatible with Angular 4. This library enables the developers to render their applications on the server side, which benefits to both users and search engines. Additionally, most of the universal code is located at @angular/platform-server. With Angular Universal, JavaScript is no more necessary for rendering the page content at the beginners’ level, so website can be enhanced better for search engine. Angular Universal is already used in different programming languages through node-Runtime.

  • *nglf, now with more else

Angular application has the most common *nglf structural directive, is now equipped with an else statement. This means no need to use two *nglf with opposite evaluations. Hence, it is easy for the developers to simplify the conditional templates.

For Instance: <div *ngIf=”userList | async as users; else loading”>

<user-profile *ngFor=”let user of users; count as count; index as i” [user]=”user”> User {{i}} of {{count}}

</user-profile>

</div>

<ng-template #loading>Loading…</ng-template>

  • Pipes

Title case: Changes first letter of each word tot tile case while other remains in lower-case

<p>{{‘abc’| titlecase}},/p>

<!—will display ‘Abc’ –>

HTTP:  Search parameters to HTTP request is made easy

http.get(`${baseUrl}/api/races`,{ params: sort: ‘decending’} });

Before you had to do:

const params = new URLSeaechParams();

params. Append(‘sort’, ‘decending’);

http.get(`${baseUrl}/api/races`, { search:params});

Test:  Overriding a template in a test has also been simplified

TestBed. overrideTemplate(RaceComponent, ‘<h2>{ {race.name} }</h2>’)

Before, you had to

TestBed.overideComponent(RaceComponent, {

 set : { template: ‘<h2>{ {race.name} } <h2>’)} );

Angular core team has made great improvements in Angular 4 and this solidifies its position as ideal front-end framework for enterprise applications. With such features introduced in Angular 4.0, it is easy for the developers to craft the scalable applications that can perform well and optimized for both server side and client side.

Top Trends for the Future of Web Development

Web development trends

Since past few years, the web development has become omnipresent – From reading newspaper, every morning to shopping and banking, it has become integral part of our lives as its presence can be felt everywhere. To utilize this wide range of opportunities, web developers need to pace up with the ever changing technologies. They must harness new frameworks, techniques and tools to enhance their ability of developing more engaging and robust websites. This makes it even more crucial for the developers to keep themselves updated of the latest trends of web development in order to create and deliver engaging websites that keeps user’s attention for significant amount of time.

Below are the top players that will change the technology landscape in the near future:

Artificial Intelligence (AI)

Artificial Intelligence is always the first word that comes to the mind, when anyone talks about future of technology. Majority of AI development have been intended to make consumer processes easier and simpler. Artificial Intelligence becomes more reality as machines learn from errors and hits to act more effectively, apply logical rules to reach conclusion, recognize patterns and can infer their reasoning from day to day.

Machine learning is one of key criteria for the website developers as Microsoft, Google, Apple and other tech giants continues to evolve the software as a solutions. For instance SIRI – she goes so far beyond voice recognition, her development was based on Pentagon AI project. The importance of AI is explained by the fact that, it enables devices to act independently without manpower and this leads to increased efficiency, accuracy and overall better user experience.

Artificial Intelligence

Virtual Reality (VR)

Virtual Reality is the future prospect of internet with which users have already started feeling in virtual environment by using computer hardware and software. VR has been primarily associated with gaming and this industry is using this trend comprehensively in web development process. The visual displays used in virtual reality enables the users to immerse in the virtual world and stop the sensory impressions coming from the real world. More websites are exploring Grand Canyon without getting out of your chair.

Google and Mozilla are making efforts to integrate API into website. With the increasing technology standards, more and more apps are expected to emerge based on VR technologies ranging from news coverage to virtual real estate tours. The Oculus Rift and Vive is about to bring new and interesting possibilities to the world of gaming.

Internet of Things (IoT)

As per the research, the IoT web development market is forecasted to grow by 31.72% (CAGR) till 2023. The internet of things (IoT) is a movement where non-internet-connected objects are given network connectivity in order to send and receive data. This enables the devices e.g.: entire house to collect data via sensors and share it with applications on remote computers. This data can be used to perk up products and marketing strategies, monitor for performance or malfunctions or track the status.

Most of these devices and apps can also work via smart phones to control features or view data. Using apps on our smart phones, we can remotely turn on heating equipments; switch on the light bulbs etc. before getting into home. Because of this, web developers are likely to develop the applications that use, analyze and display the device in order to communicate with the IoT devices.

Static Website Generators

Static websites are captivating over from dynamic websites for providing online content. Bloggers are seeking for new web development trend that ensures low costs and enhanced speed, performance and security. Static Website Generator is significantly becoming the part of web developer’s toolkit.  This creates websites from the plain text, usually stored in files and not in databases. This reduces website loading time, offers better security and make deployment of content and template much easier.

Some of the popular website generators are Jekyll, Middleman, Roots and Hugo. Many developers are considering this as a significant driver to watch out in the coming months. The main downside is that they do not have room for user content or real-time content like comments, which have become a must in today’s world. But, with APIs and Content Delivery Networks flattering more on the web and making use of templates as well as content easy; many developers are confident that this area is one of the latest web development trends to watch in 2017.

The Design

This is yet another trend that has come forth. One key area is Material Design – this outlines how an app should perform and look on wireless device. When it comes to web development, it provides guidance on patterns, components and usability. It has become a leading visual philosophy that will come in handy for developers in the coming year particularly when layered interfaces are involved.

People look for engaging and compelling ways to get the information quickly. This will likely draw a rise in the use of videos and other storytelling visuals. Bolder and larger typography are likely to become more prevalent. Apparently usability of design will have an enormous impact on how people view and interact with various interfaces.
