Node.js is one of the demanding technologies in which web applications are developed. Technology is the preferred one to create real-time applications. And being a Node.js development company in India, today we will discuss how to build real-time applications with Node.js.
Further, we have already explained the best Nodejs server-side framework for 2022 and if you are looking to know about it, check out our blog now.
In this blog, our intent will revolve around the way a real-time application is developed in Node.js. Do you know the examples of real-time applications? It is like UBER where all the executions are in real-time.
We make bookings, track drivers, make online payments, etc. All these activities are done in real-time.
Applications like LinkedIn, Uber, and Netflix are developed in Node.js. Do you know the reasons for the adoption of Node.js? The advantages of Node.js are as follows:
Further, Node.js enables quick processing of data, convenient analysis along with faster deployment of code. This is the basic concept of Node.js and now we will get to know the development of real-time applications in Node.js.
Moreover, if you are looking to hire Node.js developers in India & USA, Linearloop is your exclusive service partner.
Real-time applications are always challenging in terms of their scalability. Hence it should be given preference at the time of development. Each request of the real-time applications database queries needs to be refreshed every 5 seconds.
The concept works well when we have 10 users but sometimes it collapses with 100 users approximately. Hence, developers need to choose the right toolset in order to develop real-time applications.
Also, from the scalability point of view, the professionals should design a proper flow of data, integration points, and events. All such problems are eliminated with Node.js because it facilitates solutions to maintain the scalability of the project.
Furthermore, the leading tech giants like Paypal, Walmart, LinkedIn, and Uber are following Node.js because the technology has given them proper scalability.

Whenever we develop any application, security matters the most. As we know, in this technical era, we are dealing with positives as well as negatives. Hence we should never leave any gap that spoils the application.
Hence, high-level security is always important. We can understand it with an example. Single Sign-On (SSO) is an integrated part of the streaming applications and it must satisfy existing security layers.
Developers must ensure data protection along with data encryption, algorithms, and data in motion. Node.js based real-time applications follow security protocol.
Furthermore, we are an experienced Node.js development company in India and USA and if you are looking for any kind of assistance, feel free to connect.
The concept of real-time applications revolves around the streaming of data in order to execute the overall functionality. The streaming of data will either be on-premises or cloud.
Hence while creating real-time applications in Node.js we must have data-driven development frameworks, schemas, and data format.
Considering our years of experience in Node.js, we recommend following the concepts. Also, the technical experts use the concept to get insights, analyze the trend and develop the algorithm accordingly.
As a result, the operations of real-time applications enhance along with the business value. Also, the ultimate aim behind any business application is to save effort with maximum possible deliveries.
Depending on the statistics for the year 2020, the watching hours of live streaming content is approximately 480 billion hours. And the majority of the views are from mobile devices.
And with such dynamic usage, the real-time applications demand smart development methodologies. Hence the experts, data scientists, and data analytics study the entire concept carefully because it affects the entire adoption of the environment.
From reading the above concept, you must have understood the flow and importance of data in streaming applications. And the streaming data is a series of time-stamped packets.
This is the reason, the technical team needs tools so that they can process the time-series data conveniently.
The process of execution of workload decides the scalability of the application. And when we are talking about scalability, Node.js should be considered, especially for real-time applications.
Here we will let you know the architecture of Node.js that enhances the tolerance to the failure of the real-time applications. Because of this reason, Node.js is counted as the reliable and best programming language to develop real-time applications.
The architecture has an event-driven approach along with asynchronous nature because of which Node.js is the most preferred technology to develop real-time applications. In order to handle multiple clients, the real-time applications of Node.js use event loop architecture.
As we know, some other technologies like Spring MVC, JSP, ASP.NET, JQuery, AJAX, etc are also preferred but their approach of request-response architecture is multi-threaded but Node.js is single-threaded.
And being single-threaded, Node.js is preferred because its flexibility to manage concurrent clients is always more. Further being single-threaded, it uses fewer memory and resources. So, when it comes to develop real-time application, Node.js is favored.
So, while developing a real-time application the developers must pay attention to the streaming of data. Further, from Linearloop you can hire Node.js developers in India & USA as well.
Moreover, if you are looking to know about the frameworks of Node.js, don’t forget to read our blog best Nodejs server-side framework for 2022.
Also, we have delivered lots of Node.js projects across the globe and hence working on your requirement will be manageable for us. Also, we are ready with full support, so need not worry. You are with the best Node.js development in India.
How Server side rendering (SSR) useful to improve lighthouse score?
Server-Side Rendering i.e. SSR is a process through which the server transfers data to the browsers in order to draw a layout. With the help of SSR, an application opens a web-page directly on the server rather than rendering it on browser of the system.
Without the implementation of SSR, an application will have a group of static files that slows down the loading speed of the application.
Here, we will explain the worth of rendering and how it plays an important role to improve the lighthouse score. Apart from that, SSR enhances the SEO score for a website, and hence it becomes more significant.
Basically, the search engines like Google, Yahoo, and Bing crawl a website in order to validate its authenticity. Also, while crawling they depend on the data that comes from the server. And also, they rely on the data that is appearing after the first 8 seconds.
The crawlers of the search engines run Javascript in order to get the data, and if it takes more time in fetching, the crawler ignores the data. Thus it compromises the performance of your web page or application.
Hence those who want excellent SEO performance should always render the website or application directly from the server.
Also, we all know, the present time is too competitive and people are expecting you to be smart enough. Hence, in order to win the race, you must go smart and make your online presence vibrant and solid.
Generally, server-side rendering generates a quick FP (First Paint) & FCP (First Contentful Paint). Because of the rendering on the server, there is no need to send lots of Javascript code to the client.
As a result, we get fast TTI (Time to Interactive). Moreover, the techniques become more useful where we have to incorporate a wide range of devices and network conditions.
So, we can say that, in response to the navigation, SSR generates the full HTML for a page. Also, the activity saves time by avoiding multiple round-trips in order to fetch data on the client-side.
If we talk about the internal process of SSR, here it goes. Based on the command of the user, the server generates a fully loaded page in which the application is rendered as raw CSS & HTML.
Afterward, the parsing of the application starts, and meanwhile rendering of DOM initializes. Once all these activities complete, users get a view in order to interact with the required interface.
Moreover, the most extraordinary concept of SSR is that it doesn’t allow the users to wait for the Javascript in order to load the entire content as the server executes it already.
Are you aware of the benefits of SSR? If not, we are here to explore the same. We have noticed people try to incorporate SSR but, they are not aware of its advantages. So here you go:
With the implementation of SSR, the productivity of the application or website increases. It loads the requested content on the server-side.
Also, it quickly opens the requested web page and thus offers a better user experience. As we all know, when a web page takes time to open, users become annoyed. And it is not the case here.
In spite of having low internet connectivity, SSR helps in loading the
requested page quickly. Moreover, despite having the older device, it offers proper assistance to load the requested page.
As we have mentioned earlier, SSR loads application or web pages even more quickly, and thus it helps in improvising the position of the page on various search engines.
It happens because search engines like Google give preference to the online product that opens quickly.
As we know, the era is technology-driven, and we all know that each device has its own configuration and worth. If we talk about client-side rendering, there is a lot of dependency on the capability of the device.
Also, we have experienced lots of cases where the devices were not capable to render the entire application in the given time. As a result, the quality of the application compromises.
Also, the bounce rate and loading time are directly proportional to each other that ultimately decreases the performance of the site.
However, SSR works differently because it allows the loading of data on the server-side that does not depend on the configuration of the hardware or devices.
Hence, server-side rendering is capable of delivering a consistent result that further brings more clients’ engagement on the page. As a result, the performance of the site increases.
Lighthouse: Before going into the deeper discussion, let’s understand what is Lighthouse? As per the definition of Google, the lighthouse is an open-source, automated tool that helps in improving the quality of your web pages.
Also, Lighthouse runs tests and share its audits that helps developer to make a website even more user-friendly.
Furthermore, Lighthouse plays an important role in examining the important elements of a website. If we focus on its result, and make required improvisation, the overall performance of a website improves.
With the help of Lighthouse, we can analyze our web pages on various parameters, and those are
The report of Lighthouse offers recommendations to optimize the web page on the required parameter.
For example: Suppose texts are not properly visible when Webfont loads. In such a case, Lighthouse will diagnose the problem and ask the user to take the required action to resolve the issue.
If you are browsing to know about the technologies that help you to set up SSR, this section is for you.
Here we are elaborating the two important leading technologies that will surely help in setting the SSR for your web pages and applications. Let have a quick look.
You must be aware that Next.Js is a framework that helps in creating SSR React applications. Moreover, the framework is also very useful to create a full backend of the applications because of being server-side.
Basically, the Next.Js is divided into 2 sections in which the former is “SSR” (Server-Side Rendering), and the latter is “The Backend Server”.
Being a server-side, the framework generates HTML and sends it to the client while, as a backend server it supports APIs.
Also, Next.Js has two modes to fetch data i.e. getServerSideProps and getInitialProp
The server-side rendering (pre-rendering)
There are two ways through which Next.Js renders the web pages. These are
As the name states, one can generate HTML only once on the server at run time. Also, the same HTML will be reused upon each coming request.
We recommend this approach where we need better performance and cache. Obviously, the method has some limitations because one can use it only at run time.
Under this process, the formation of HTML takes place on the server corresponding to each request of the client.
Here, the generated HTML will be dynamic in nature and relies on the data. Every time, it generates the new HTML by considering the data fetched.
Do you know, why should we prefer Nuxt.Js? If not, check out the reasons now. Nuxt.Js has certain capabilities that make it advantageous, and these are:
Using Vue with Nuxt.Js makes SSR implementation even more advantageous. Also, at the same time, we would suggest deciding the technology for SSR at the very beginning of the project otherwise things will become messy.
As we are dealing with technology so, we always are proactive and make plans prior to moving into the development
So, here we have mentioned the concept of SSR and how it helps in improving the Lighthouse score. We certainly hope that you have got an idea about the concept.
As the time is changing, we all should also use the best method in order to sustain our product in the market.
Linearloop is one of the progressive IT software development companies across the globe, and we always encourage people to follow the best practices of the technology. Feel free to write us if any query hits your mind.

Node.js vs Python: Which Backend Technology to choose in 2021?
Developers cannot decide on any backend technology depending on their choice because it must be as per the demand of the project. While planning for web app development, it may be possible that you find Node.JS beneficial for the project.
On the other hand, there are many other web development services that demand Python. Hence depending on the project demand, developers choose the required backend and front technology.
The ultimate aim is to execute the project on time by meeting the complete requirement.
In this blog, we will compare Node.JS Vs. Python for backend technology on various parameters. As a result, you will get to know which one is better and when. See, nothing can always be good or bad.
The same applies to these technical aspects as well. So let’s analyze Node.JS Vs. Python and see which is better.
Architecture is one of the important parameters that is always considered while choosing any backend technology. Hence, Architecture is our first parameter based on which we will compare Node.JS vs. Python.
If we focus on Architecture, here Node.JS will be preferred over Python.
Now we will compare the technologies based on their libraries and dev tools.
Hence based on libraries and development tools, Node.JS becomes the choice.
Node.JS Vs Python performance has been analyzed here and a final conclusion is drawn for better performance. Hence if you are planning for web app development, keep this parameter in mind.
Based on the performance, Node.JS wins here. It is fine, Python is simple to understand but speed is the concern here. So if performance is the parameter, the web application development services should go with Node.JS.
Now the comparison of Python and Node.JS is done on the basis of their scalability. So let’s have a look.
When scalability comes, Node.JS should be given preference for web app development.
As we have stated earlier, the selection of any technology or programming language is completely dependent upon the requirement of the project and the expectation of the client.
Being leading software development company, Linearloop always recommends analyzing the requirement properly. Afterward, you should select the best-suited backend technology that can either be Python or Node.JS. Let us know if you are looking to know more.
