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.

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.

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.
