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.
