December 14, 2022 2198 Views

As the need for different types of web applications is increasing, the demand for web application frameworks has also skyrocketed. A web application framework provides a set of tools and libraries that simplify common tasks involved in web application development. Thus, these frameworks improve productivity and accelerate web app development. 

Creating a web app without a web application framework may have been a common practice back then. But that’s not the case today. Today’s modern web applications have become increasingly complex in nature, with features like interactivity, responsiveness, real-time updates, and more. Thus, web developers worldwide now use web frameworks to create high-performance modern apps quickly.

In this post, we will:

  • Discuss the basic concept of web frameworks
  • Different types of web frameworks 
  • Explore the features of popular web frameworks 

What is a Web Application Framework?

A web application framework is a piece of software that facilitates the development of web applications. These frameworks simplify and standardize the development process by providing a range of tools and resources for common tasks involved in web app development. 

Web frameworks basically speed up app development by minimizing the complexities associated with it. All in all, web frameworks lay a robust foundation for your web development projects with a set of predefined configurations.

A web framework can support one or multiple programming languages, depending on the type of framework.

Types Of Web Frameworks

Web development frameworks are typically divided into two categories: front-end and back-end.

Frontend Web Application Framework

Front-end of a web app

Front-end frameworks are used to develop the client side of the application, which is the part that users interact with.  

In other words, we use a front-end framework to create the user interface (UI) of a web application. This includes:

  • The design of user interfaces
  • Handling user experience
  • Building reusable components
  • Performance and SEO optimization.

Front-end frameworks are often composed of three core technologies:

Most modern front-end frameworks use a component-based architecture where the UI is broken down into reusable components. Each component has its own structure, styling, and behavior. 

Examples of popular front-end frameworks include Ext JS, React, Angular, and Vue.

Backend Web Application Framework

Back-end of a web app

Back-end frameworks are designed to facilitate the development of server-side logic .Thus, these frameworks are also called server-side frameworks. 

Backend frameworks provide all the necessary tools and libraries to manage the background functionality of your apps. This also includes:

  • Database interactions and management 
  • URL mapping and routing 
  • API creation
  • Building the app’s overall architecture
  • Server management
  • Security features

Examples of widely used backend frameworks include Ruby on Rails, Django, Express, Spring, and ASP.NET

Why Use a Web Application Framework?

Benefits of using a web application framework

Faster Development

A web application framework makes the lives of developers easier by providing a pre-defined codebase and a set of guidelines for web development. 

Thus, developers don’t have to code everything from scratch and can use the standard templates provided by the framework. This speeds up the app development process.

These web frameworks even automate essential development tasks such as URL mapping, caching, and session management, leading to a more efficient development process.

Enhanced App Performance

Many web frameworks offer additional features, such as live reload and hot reload, to enhance the performance of web apps.

Furthermore, these frameworks provide tools and packages to incorporate advanced functionality into web apps easily.

Enhanced Code Readability

Web frameworks also provide a responsive development environment and enhance the quality and readability of code. This, in turn, improves the code efficiency. 

Facilitate Code Resuability

Many web frameworks facilitate code reusability, allowing developers to use the same code base for developing different apps. It saves a great deal of development time by eliminating the need to rewrite complex code structures with thousands of code lines. 

Debugging and Maintenance 

Frameworks also play a key role when it comes to debugging and maintaining web applications. Some frameworks come with built-in support for QA testing and debugging.

High-Quality Apps

Web development frameworks help deliver more quality web apps with reduced time-to-market. 

The apps built using web development frameworks also have much tighter security due to the built-in security offered by the framework. These security features help protect your apps against common cyberattacks such as DDoS attacks, SQL injections, and data breaches.

Popular Web Frameworks

Let’s explore some popular web frameworks used by thousands of developers across the world.
