What are Backend Web Frameworks? Which one you should go within 2021?


What are Backend Web Frameworks?

Backend web frameworks are libraries of server-side programming languages that help build the backend structure of a website. Backend web frameworks provide ready-made components for developing a dynamic web framework. Using frameworks gives a head-start to the developers by eliminating the need to build and configure everything from the ground up. The web developers can use backend web frameworks to make applications in a faster and standardized way.


Why do we use Backend Web Frameworks?

According to Wikipedia, a web framework’s main objective is to automate the overhead correlated with software development activities. The core advantages of using a framework for development are:


  • Time-Saving
  • Scalability
  • Robustness
  • Security
  • Integrations


On top of that, most of the web frameworks are Open-Source.

What is the difference between Frontend Web Frameworks and Backend Web Frameworks?

Any web development project is usually divided into two core phases: Frontend web frameworks and backend web frameworks. Frontend web framework refers to the development of the things that users would see and experience while using the web app. On the other hand, the Backend web framework handles functions such as data storage, security, scalability and data transformation. A good example is a car, whose body, dashboard and steering is essentially your frontend and defines the experience you have with it. However, this experience will not be complete without the engine, chassis and the fuel tank of the car (backend).


Which Backend Web Framework is right for your Web Development Project?

Backend web frameworks are vital to the successful function of any web development project, unless the webpage you require is a static one. The easiest way to have such a web page in our opinion is to create one on WordPress as it allows for basic content and user management. However, such backend web frameworks are not useful for creating custom web applications with sophisticated requirements our clients require from us.
