Stack for Web App Development in 2020

Though we live in the mobile-dominated age, web applications are still prevalent and a preferred choice for enterprises for certain features. Progressive web apps is an example of the web app’s adaptability and capability to act like mobile apps. It is fair to mention that web applications are here to stay. As technology evolves, many advancements arrive for developing a web application with desired features.

Web App

However, for building a successful web application, you need to choose the right blend of technologies or a high-quality technology stack. The proper technology stack can increase your web application’s market reach and make the entire web app development project successful. The technology stack has a direct impact on the performance of the web application. Once you identify the right technology stack, you can hire full-stack web developers for your project.

Looking at the importance of choosing the right technology stack, here we cover every aspect related to the necessary factors and structure of various technologies. But, before digging deep into the topic, let’s find out the meaning of a technology stack.

  • What is technology stack?

Technology stack is a combination of all technical components like tools, programming languages, frameworks, and technologies useful for developing customized software. When it comes to web app development, we need to think about the structure of technology stack from two aspects-

• Front-end
• Back-end

Let’s go through them one after another.

Front-end Web Development Technologies
Front-end web development enables users to see and interact with your app. Web browsers like Safari or Chrome are responsible for user interaction. As the front-end development is responsible for the user interaction, technologies used in it are known as client-side technologies.

• HTML and CSS
Hyper Text Markup Language (HTML) and Cascading Style Sheets (CSS) are like the backbone of web development. HTML is useful for designing the front-end portion of web pages by defining the link between the web pages. CSS, on the other hand, makes the web pages appealing by managing the design components. Simply put, HTML makes the web page while CSS gives style to it.

• JavaScript and Related Libraries
JavaScript is a scripting language for making the website interactive. When it comes to web app development, it can enhance the web app’s functionality. AngularJSReactJS, etc. are popular JavaScript-based frameworks that are extensively used for developing user-friendly and interactive web apps.

Backend Web Development Technologies
The back-end web development is designed to powering the front-end while enabling users to perform specific actions. This part is not visible to users, and therefore, it is known as server-side technologies.

Backend technologies consist of programming languages, servers, and databases. Here we go through some of the important programming languages and databases.

Programming Languages

• PHP– It is a server-side scripting language. As the most popular and preferred language, PHP empowers many websites and web applications. CakePHP and Laravel are important PHP-based frameworks for developing customized web solutions.

• Java– It is also one of the most popular and useful programming languages for developing web solutions. It is a highly scalable and flexible language to build a successful web application.

• C++– It is a highly-used programming language for competitive programming. As a backend language, it is used to build a customized web application.

• Ruby– It is a reflective, object-oriented, dynamic language. Everything available in this language is in the object form. However, procs and lambda are replacements of Ruby’s components in blocs.


• Oracle– This database treats the collection of data as a unit. Oracle enables users to store and retrieve information on any query. It is useful to manage information efficiently.

• MongoDB– It is the most popular, open-source, document-oriented NoSQL database. Here ‘No’ denotes as ‘non-relational’. MongoDB is not dependent on the table-like relational database but provides a completely different mechanism for storage and data retrieval.


• Nginx– It is an HTTP and reverse proxy server, a generic TCP/UDP proxy server, and a mail proxy server.

• Apache– It offers a high-level of abstraction for processing. It also provides a high-level scripting language Pig Latin to develop a data analysis code.

After looking at various popular technology stacks, let’s go through top factors to consider while choosing the right technology stack.

  • Which Factors Should You Consider While Choosing Technology Stack?

Every web application has a different size and feature requirements. Other important factors are scalability, duration, security, and web app development cost.

Let’s discuss all the important factors for developing a web application with desired features and excellent functionality.

App Size
The size of your web app matters the most while selecting the right technology stack. The reason is simple- if your web app is large, it becomes more complex, and therefore, you need a more advanced and robust tech stack.

Small web apps– These apps consist of 1 to 3 web pages, portfolios, and other web-based solutions. Such apps do not require much time to develop.
Med-size web apps– Apps for financial sectors, online businesses, etc. fall under this category. They need a more complex and advanced technology stack than small apps.
Large web apps– Social networking apps and on-demand marketplaces are considered as large web apps. They need higher performance, scalability, and serviceability as compared to mid-sized and small web apps.

Competitive programming- Algorithm skills

We all know that competitive programming consists of coding contests and events. Under these events, participants have to write programs/codes under given specifications. Many multinational tycoons such as Facebook and Google conduct and admire CP events. Some of the most popular competitions include Google Code Jam, ICPC, Russian AI Cup, and CodeChef.


Competitive programming is majorly a sport, but a mental one. It tests your competitive spirit and competence towards a particular ability.


The oldest contest known is the ACM-ICPC (International Collegiate Programming Contest). It was held at Texas A&M University in 1970 hosted by the Alpha Chapter of the Upsilon Pi Epsilon Computer Science Honor Society (UPE). The programming language used was FORTRAN.

CP is a good platform for programmers to up their game. Competitive programming could also lead to better bids and offers in freelancing sites. Now coming to the point, here is our guide to competitive programming. This will help you make better decisions and make the best out of CP.

Programming language

I would suggest you learn C, C++ or Java. Learning C++ is easy if you understand C easily. You should learn C++ since it has a standard template library that contains functionalities like vectors and sets. These come handy while solving specific problems.

Java is also a good option since it is used by a few top coders, and also the commands are easy to understand. So this is the first step to competitive programming. What next?

Apply on competitive programming portals

First, go for HackerRank. They have fairly easy questions, a plus for beginners. Also, its user interface is convenient.

It has a test in which there is a mixture of easy and medium questions. The questions are generally simple for someone with zero experience in competitive programming. He/she will solve the first few questions. Try to attempt all the easy level questions, and it is fine if you solve a lesser number of medium questions. Moreover, this is enough to fetch you a call from a HackerRank CP executive.

Now, apply on CodeChef and Codeforces.

CodeChef conducts long competitions, which helps a programmer improve his/her deep thinking.

Codeforces is popular for its 2-hour rounds. These contests are recommended if you want to increase your thinking and coding speed. In a nutshell, taking part in these two portals will make you a good programmer. How?

You become competent in two skills, deep thinking, and coding speed. Still, it is okay if you are interested and/or competent in any one of these portals. Because this will help you become a better programmer.

Competitive programming facts

  • In competitive programming, coders solve coding problems using algorithms and data structures.
  • Skills required for CP are basic math, algorithm, programming and typing speed.
  • It’s a myth that it’s too late to start CP. The fact is, there is no fixed age to join CP.
  • With CP, a coder may become a master of coding, but lack knowledge of frameworks. Frameworks are important for real-life projects.

Final word

Optionally, you can apply to TopCoder. The secret to getting proposals from Google and similar tech giants is to be consistent. Therefore, participate in contests, try to improve your rank, and build your rating.

Alternatively, you can do competitive programming on the side and also learn practical skills. Your decent CP experience combined with requisite practical skills will enable you to get all those jobs and internships you dreamed of.
