Top 3 back-end technologies for web applications

aTeam Soft Solutions March 25, 2021

Synopsis- While making a fresh website, developers need to concentrate on both frontend and backend development. The Back-end technologies cooperates with the server and delivers content or information to be shown to the clients. So the backend code manages the application and the web server and database. The mix of utilization, server, and database makes the backend coding both mind-boggling and significant. So today we’ll walk through the different aspects of backend technologies and their further development.


What are the backend technologies?

Backend is the server-side of the software that stores and analyzes data and guarantees smooth application performance. Backend developers take on a scope of duties, like writing APIs, and libraries and working with framework parts, business cycles, and data architecture. Being a cycle that stays undetectable for clients, backend development sends and gets data, speaks with the frontend, and shows the data as a website page.

Frontend and backend technologies are the most fundamental terms of software development. Backend technologies are responsible for the server-side, while frontend tools refer to the client-side of the application. The two sides need to work faultlessly for the software solution to be viable and responsive.

Criteria for selecting the top backend technologies

The troubling inquiry for a technology start-up or an organization embracing new technology is picking the ideal programming language. The inquiry can be responded to utilizing these three elements Problem domain, Characteristics of the Language, and the Organization’s technical ability:

  • Issue Domain – Every innovation has its own business use, and utilizing that benefit will settle the decision cycle more smooth out. For instance, .NET is the favored decision for flexible and business web application building. If you are searching for enormous data analysis, for example, forecasting weather conditions then Python may be the most ideal choice. If enterprise-level security for a business-to-business application is basic; you will probably need to explore utilizing Java. In this way, your assessment should consider the issues you want to address and your business case, and sort of clients.
  • Language Characteristics – There are various languages accessible to programmers. Be that as it may, how about we limit the conversation to the languages which are famous and broadly utilized. Every language has various attributes, networks, support, and ecosystems that impact the dynamic interaction.
  • Technical Skill – Picking the right back-end innovation needs sound information on frameworks, languages, servers, and so on. The decision on technology will rely upon the technical capacity of the group. The accessibility of a talented workforce will fluctuate by geography. Participating in meetups, client gatherings, and co-working spaces to draw in local ability that can assist in working with joining aptitude. Eventually, your expenses for developers will go up if the abilities you want are not promptly available or are popular. On the other hand, the enterprise can outsource the web application to technology-based businesses.

#1. Express js

Express.js or simply Express is an open-source and free framework that can be used for Node.js. It is a Sinatra-inspired server. This means that it’s minimal.

The official description on the website of Express states: Express is a fast, unopinionated minimalist web framework for Node.js.

Express was founded by TJ Holowaychuk in early 2010. Later in 2014, the rights were acquired by StrongLoop.


  • Scalability : With Express, you can quickly scale your application in any manner, using the advantage of its support for Node.js and additional sources.
  • Easy to learn : Since express runs primarily on Javascript, you don’t need to learn a lot of languages. And JavaScript is easy to learn.
  • Duality : Express is a combination package. You can use it to code both Front-end and Back-end technologies using Express. Several platforms enable that, but not quite efficiently as Express does.
  • Cost-management : Since Express is a Full-stack development framework, it can save you tons of bucks, which you would have to pay if you had to hire a developer for the front end separately.

Companies that trust their Back-end technologies responsibilities with Express:

  • MySpace : We don’t even need to introduce this website. MySpace was a popular blogging site in the early 2000s. MySpace uses Express for its Back-end technologies development.
  • Netflix : Netflix is one of the most popular video streaming platforms in the entire world. Netflix switched to Express to leverage their performance.
  • NASA : NASA is the pioneer of aeronautics. They were facing difficulties in accessing databases for research purposes. That access was slow and required rummaging. So, NASA switched to Express which dramatically improved their database access timing.

If you want a simplified process without having to learn many languages, Express is the option for you.

We love using Express because it’s simple, effective, and satisfies both front and back end needs.

When to use Express js?

The most precious thing in the market is time. This is where the express js comes to the rescue. It can lessen the coding time by half and still can witness an effective result. It not only lessens the time but also lessens the exertion with the support of various features. Another reason to utilize Express js is JavaScript. Express js even permits fresher to enter into the web development world due to its JavaScript element. Javascript is very easy to learn for any developer even if they don’t have basic language knowledge.  Hence, it permits youngsters to step into the web application industry and accomplish goals.

It also gives easy routing for requests made by customers. It also gives the middleware i.e. responsible for decision-making to provide the correct responses for the clients. Without express, you might have to write your code component. You can make any kind of website, web apps, or even mobile apps using express js. 

#2. Laravel

This PHP framework helps in the development of high-end applications. It is an open-source toolbox. Laravel follows a Model View Controller (MVC) architecture pattern. This pattern is based on Symfony. Some of the core features of Laravel have a packaging system with a dependable approach, multi-way accession of relational databases, this, in turn, leads to application deployment and maintenance.

In hopes of getting a better alternative for CodeIgniter, Taylor Otwell created this application in early 2011. Its beta official was released on June 9, 2011, followed by an official release shortly. Currently, Laravel is running its 8th version.


  • Authorization : Every website owner wants their website to secure and safe. It is needed to be sure that the user is who he claims he is since some places require gaining access to security/pay portals. Laravel provides a very simple yet effective way of authorization with logic and control while accessing information.
  • Mailing : When you think of a website, it is almost impossible to not think of it having mail. Mail is required to send out notifications about registration, various events, offers, etc., Laravel provides support for notification delivery via various channels through a local or cloud-based service. Laravel opts for a clean and simple API, instead of the popular SwiftMailer library.
  • Binding of tools : It is crucial to create fast applications, as this accelerates the revenue. The Binding of caching is important to improve performance. Laravel largely supports Memcached. By default, it is set to use the file cache driver. With Laravel, one can even customize various cache configurations.
  • Fixing the Vulnerabilities : Security-related loose ends go hand in hand with web applications. SQL injection, cross-site scripting, etc., happen to be a couple of them. One must keep in mind to fix them before it is run. Laravel’s codebase is strongly secure and guarded, this, in turn, helps in getting the major vulnerabilities out of the land.
  • Error handling : User satisfaction is mainly based on how the software handles various errors. Most errors are countered when a user hits the submit button on a form. If it’s something that the user did wrong, he/she needs to be notified about it with an informative error message. If he/she isn’t informed this will make them think that the website is not working, or out of service which will further push them to not use it ever again. Laravel is configured with the Monolog logging library which supports a good number of log handlers. This will reduce errors and exceptions.

Some of the companies/platforms that trust Laravel:

  • 9GAG : 9gag is a social media and an online platform. It allows users to share witty content.  9gag uses PHP, Laravel, and Vue.js for the better functioning of their website.
  • BBC : BBC is one of the well-renowned broadcasting organizations. Traditional media aside, they also happen to run multi platform applications. They use Laravel along with Angular, for an overall great experience.
  • Ratio : Ratio is a UK-based financial management website, it is an innovation of Fintech. They use Laravel and React.js for efficient browsing and product experience.
  • Pfizer : Known as one of the largest pharmaceutical brands in the world, Pfizer, utilizes Laravel in the career section of their website.
  • TourRadar : Known for its ways of helping travellers compare and book their tours, TourRadar uses Laravel as a backend framework.
  • Crowdcube : CrowdCube is one of the largest crowdfunding platforms. They primarily use Laravel/MySQL coupled with a couple more frameworks.

Laravel is a great option if you have a limited budget but want an advanced and scalable website. Lastly, we like to use Laravel because it provides a secure and hassle-free way of coding.

When to use Laravel?

Laravel can be utilized for construction websites as well as web applications in view of object-oriented programming principles and the MVC architecture. Because of countless in-built tools, developers that utilize Laravel can make solutions of any intricacy and any scale, from one-page sites to full-fledged social networks.

One of the primary Laravel benefits is that all the development processes are made as basic as could be expected. It doesn’t make any difference how complex the project’s architecture and business logic will be. With Laravel, you can undoubtedly defeat any hardships with testing, shaping routing mechanisms, authentication, eCommerce, security, and so on.

#3. Loopback

Loopback is a highly extensive, open-source Node.js framework. It enables you to create dynamic, and secure APIs that can be called by any client. LoopBack comes with a built-in client API explorer. This makes the view of the work easier.


  • Faster procedure : Since LoopBack comes with a great number of built-in models and gestures, the processing times reduces by a greater degree.
  • Structure : It has a great out-of-box structure that allows us to add codes easily and consistently.
  • Sharing : Since loopback is a redesigned framework, it enables the engineers to share code and create services on the client’s side.
  • Dedicated documentation : Loopback has a built-in SDK generation tool and API documentation.

Companies that trust Loopback with the mess:

  • Go Daddy : GoDaddy is an American domain trading and web posters company. When you want to buy a domain name, you can use this website to do so. Go Daddy is loyal to LoopBack for its Back-end technologies development.
  • FlightOffice : FlightOffice is a British Airways operator, they use LoopBack for their website.
  • Haven, Inc : Haven, Inc., is a logistics generating company. It generates logistics for ocean freight companies. Haven is considered a pioneer in the field of shipping logistics. HavenHaven uses LoopBack for their backend needs.
  • Foko : It is a retail management website that allows mobile store operations, marketing communications, and store audits. It uses Loopback as its trusted Back-end technologies development tool.

If your app needs to be broken down into entities, you should opt for Loopback.

We love to use Loopback as it comes with inbuilt and processed functions which leads to saving developmental time. It can be really messy when you have to choose a framework for your needs. Below we are going to compare the aforementioned developing tools.

Express vs Laravel

Express is a lightweight framework with sufficient plugins provided but if you want more then you should definitely opt for Laravel since it provides more built in tools, the only downside is that Lavarel is a heavyweight framework.

In terms of security, Laravel wins the case. It has more authentication than what Express has to provide.

In the case of maintenance, Express is easy to maintain and work with since it’s full-stacked, whereas the maintenance of Laravel is a little bit over.

Where debugging is concerned, Express wins the case since you don’t need to compile your code every time you debug. While Laravel might need a couple of compiling.

Express vs Loopback

In terms of flexibility, Loopback wins it since it is an enhanced modification of Express. When we speak of learning how Express clearly wins that part. If you are working on a small package, Express is a win-win, but if you are working on a more complex application then you should opt for Loopback.

When to use Loopback?

When a network interface is disconnected like when an Ethernet port is turned off or Wi-Fi is switched off or not related to an access point; no communication on that point of interface is conceivable, not even communication between your PC and itself. The loopback interface addresses no genuine hardware except for exists so applications running on your PC can constantly associate with servers on a similar machine.

This is significant for troubleshooting (it tends to be contrasted with thoroughly searching in a mirror). The loopback device is in some cases explained as purely a diagnostic tool. However, it is also useful when a server offering a resource you want is running on your own machine. So if you have any desire to experience a similar site others do, the best course is generally to connect with your own server. The loopback interface works with that.

Which is the fastest backend technology?

FastAPI is a Python 3.6+ framework intended for making APIs that adjust to the OpenAPI (Swagger) standard. FastAPI was created by Columbian developer Sebastián Ramírez and is quickly turning into a well-known framework as a result of its emphasis on elite execution. It depends on Starlette and Pydantic which is the reason it’s so quick. Starlette is a lightweight toolbox for creating web services. The benchmarks for FastAPI are noteworthy, showing that it’s one of the quickest backend technologies contrasted with others like core. Its fastest speed is because it’s worked over ASGI (Asynchronous Server Gateway Interface) meaning it will run different assignments simultaneously.

FastAPI is worked with current Python elements like type declaration aiding editor support and code completion. Pydantic gives it worked in approval for fields like JSON, UUID, email, and so on. It also furnishes incredible security with JWT tokens and API keys.

It scores well as far as convenience as well. FastAPI is worked to limit code duplication and has automatic documentation. It assists with preparing your task to production-ready code as quickly as could be expected, which is a reward for product managers and developers the same.

What are the latest trends in backend technologies?

Backend technologies play an essential part in the development of any software item. Whether you’re a startup leader, IT executive, or a chief, picking the right technologies is vital for your project. So let’s take a look at the 5 new trends in backend technologies that will help in any leading organization:

    • PHP  will always be number 1 as it’s impossible to visualize the whole World Wide Web without it. PHP (represents Hypertext Preprocessor) is a well-known broadly useful scripting language intended to produce HTML pages on a web server and to work with databases. Most hosting providers today support PHP. It’s a piece of LAMP, a standard set of instruments for web development that contains Linux, Apache, MySQL, and PHP (Python or Perl, at times). Almost more than 70% of websites uses PHP.

    • Python is a significant level, universally useful interpreted programming language. Code written in Python is handled by an interpreter without preliminary compilation. It’s one of the most well-known, strong, and widespread programming tools ideals for some assignments from web development to machine learning. Python is stage autonomous, easy, adaptable, and steady. In addition, the extraordinary kinds of open-source frameworks assist developers with saving time and making the development cycle more cost-effective.

    • Java is a broadly useful, object-oriented programming language ruling web and Android development, particularly on the enterprise level. Java’s code is first converted into a platform-independent bytecode that is then performed by the Java Virtual Machine (JVM). It’s a language’s key component recognizing it from standard interpreted languages like PHP. Another huge benefit is Java’s strong memory management.

    • The list of successful backend instruments isn’t restricted to just programming languages. We picked Node.js as one of the most impressive and famous instruments for application development. Node.js is a cross-platform, open-source, backend runtime environment that changes JavaScript from an exceptionally specific web tool into a general programming language for making cross-platform applications. It allows developers to enjoy the entirety of JavaScript’s advantages without browser restrictions and free from outside web servers.

    • Nest JS is the most well-known moderate Node.js framework for making solid, effective, and versatile server-side applications. Developers use Nest.js to write versatile, testable, and approximately coupled applications. It gives the right balance between construction and adaptability to oversee code in enormous projects.

Which language is best for backend technology?

Below are the top 4 backend languages used by most of the developers and their USPs responsible for the best data storage and web page functionality:


  • Python’s USP is the design of its language which is easy, rich, useful, and furthermore strong.
  • It is the standard bar set for engineer experience and has impacted various programming languages like Julia and Go.
  • It is one of the most incredible backend languages for Web Development that has top-notch integration with programming languages like C and C++.
  • It also has a skillset for the weighty projects of the CPU to C/C++ in a consistent way.
  • Python offers an overflow of toolsets for computational science, measurements, and arithmetic with various frameworks and libraries including SciPy, Pandas, Scikit-Learn, and NumPy.

 2.  PHP

  • PHP is a profoundly useful programming language utilized in the field of Web Development.
  • It is immeasurably utilized in the web business to fabricate and deploy applications at a fast speed.
  • Facebook, one of the most famous and unmistakable social media apps, is created utilizing PHP.

3.  JAVA

  • Java is a multi-paradigm, feature-rich, interpreted, and strong programming language that gives high efficiency to engineers and a moderate learning curve.
  • Because of its backward compatibility, Java is a critical business application need.
  • Dissimilar to other programming languages, for example, Scala or Python, Java has never presented any significant updates and transformations, which is the reason it stays the best option for most organizations.
  • The runtime of Java, Java Virtual Machine (JVM), is among the best VMs in the IT business.

4. C++

  • As far as developer experience, Java deficit behind C#.
  • C# has an army of frameworks and libraries since it has been in the IT field for more than 20 years.
  • Very much like Java, even C# is autonomous of platforms because of the Common Language Runtime (CLR).

Limitation of JavaScript as backend technology

JavaScript is a lightweight, interpreted programming language. It is intended for making network-centric applications. It is complementary to and integrated with Java. It is extremely simple to execute as it is integrated with HTML. It is open and cross-platform. We can’t regard JavaScript as a complete programming language. It deficit the following significant elements:

  • Client-side JavaScript doesn’t permit the reading or writing of files. It has been saved for the sake of security.
  • JavaScript couldn’t be utilized for networking apps since there is no such help available.
  • JavaScript doesn’t have any multithreading or multiprocessor abilities.

Limitation of java as backend technology

Java is quite possibly one of the most practiced languages in the software industry because of its practicality and platform-independent elements. But like any other language, it also has some limitations that are as follows:

  • Execution – Java programs take a long duration to run compared to C/C++.
  • Memory – Since Java programs run on top of Java Virtual Machine, it takes extra memory.
  • Expense – Since memory and processing needs are higher, hardware price increments.
  • Low-level programming – There is no help for low-level programming in Java-like pointers are absent.
  • Trash collection – There are zero commands over trash collection in Java. That is a programmer that has no privilege to control the trash collection. Java doesn’t give capabilities like delete (), free ().
  • No Unsigned kinds – unlike C/C++, Java doesn’t uphold unsigned int, unsigned char, and so on.

Skill to look for when hiring a backend technology developer

Let’s take a look at a few abilities you must have as a backend engineer. You must pursue gaining these priority abilities to break backend developer interviews at the greatest tech companies:

  • Backend Programming Languages – A high-priority expertise to break a backend engineer interview is to be great at Object-Oriented Programming Languages. It’s not necessary to have a master’s in various languages. However, if you’re great with one language, that’s okay. Backend developer inquiries questions normally test your knowledge in Python, Java, Ruby, or PHP. Of these, Python and Java are all the more regularly utilized.
  • Data Structures and Algorithms – Your information about algorithms and data structures is one more key region tested at backend developer interviews. DSA ideas feature in different rounds of coding interviews (technical telephone screen and the on-site interview) and are an essential strategy to test your critical thinking abilities.
  • Distributed Systems Design- Another unquestionable requirement for backend engineer ability is knowing distributed systems design. It is a key assessment region in backend developer interviews. Questions ordinarily highlight core design ideas like loading, caching, databases, network protocols, MapReduce, API modelling, concurrency, sharding techniques, and design case studies.
  • Databases – Websites need databases to store and recover client data. As a backend developer, overseeing databases is a critical part of your job. A perfectly coordinated database assists to alter, recovering, and overseeing data proficiently. Your information into SQL and NoSQL databases is assessed at backend developer interviews, so make a point to get a master of these organized question languages.
  • APIs – API modeling is another priority expertise assessed in backend engineers’ interviews. Backend engineers are supposed to have exhaustive information on APIs, as they empower interactions among clients and servers. Backend engineer inquiries on API modeling displaying features in design rounds of technical interviews.

Responsibilities of a backend technology developer

Developers make Back-end technologies, code, and work on the server, server-side applications, and databases when joined with front-end codes, assisting with making a functional, consistent experience for the end client. They concentrate on industry trends, make or further develop Back-end technologies cycles and codes, and work with others to design a superior program. In addition to this, there are other points of responsibilities regarding a backend tech developer:

  • Compile and examine data, processes, and codes to troubleshoot issues and recognize regions for development.
  • Teaming up with the front-end engineers and other colleagues to lay out targets and design more practical, cohesive codes to improve the client experience.
  • Creating thoughts for new projects, products, or features by observing industry developments and patterns.
  • Recording data and revealing it to legitimate gatherings, like clients or leadership.
  • Participating in proceeding with schooling and training to stay current on prescribed procedures, learn new programming languages, and better help other colleagues.
  • Taking lead on projects, depending on the situation.

How to hire a remote backend technology developer?

Employing a remote backend developer is definitely not a simple job. So below is every step in detail that is engaged with the employing procedure:

  • Put out exact data about the needs – with regards to developers, you can’t comprehend the mastery and abilities level without going through a thorough test. The first significant step is to put out exact and accurate information about the opening of different industry sites and enormous portals.
  • Filter out resumes – Social networks can make your occupation simple. Suggestions like friends of friends are a valid approach to tracking down the ideal individuals. You can also put out opportunities for topical gatherings. This technique has likewise worked for many.
  • Check the applicant’s portfolio – With regards to portfolios, you should be extra cautious about the finished activities. Commonly, there are up-and-comers who have an enormous number of stages and languages recorded on their resumes’, however, have extremely less instances of finished projects.
  • Interview – if you have shortlisted a resume’ you can welcome that developer for a meeting. The meeting can occur in different stages, for example, through email, or online communication where a gathering of technical experts gets some information about a few perspectives like experience, development process, technical information, and so on. When that is finished, then you can have eye-to-eye meetings.
  • Applicant sorting – Meetings assist a great deal with screening out countless up-and-comers in this manner leaving a couple of value ones. Commonly, it happens that an expert developer with a nice pay knows a specific stage and language but is totally unaware of the essential stuff.

This is an immense issue as it can influence the performance, application security, and code quality at the earliest reference point of the project. That is the reason why the essential inquiries concerning the structure of a language, security, and examples of object-oriented programming are sufficient to find out about the applicant’s level. 

What is the average salary of a backend technology developer in India?
