What is Framework

The term ‘framework’, in general, refers to a basic structure that serves as a support for developing something. Alternatively, you can define a framework as a foundation and build something on top of it.

Let us consider that you are constructing a house. As you know, the foundation and frame of a house are the elementary components that you need to build. However, what if both of them are available already? Well, in that case, it would save you from doing everything from scratch.

Similarly, in computer programming, a framework acts as a foundation for building various software. However, you need to keep in mind that only the foundation and frame do not make a complete house. Likewise, a framework is not everything that you need to develop top-notch software. Besides using a framework, you need to use other development tools that allow you to add advanced-level functionalities to software and make them work smoothly.

This article will help you understand what exactly a framework is and its importance in software development. Further, we will walk you through some different types of frameworks out there.

What is Framework?

A framework in computer programming is a layered structure that acts as a foundation for developing applications. Software developers use a framework to build applications quickly.

You can also consider a framework as a conceptual structure or template having various tools and modules that facilitate the development of robust applications.

Frameworks help developers to concentrate on high-level features of the application under development, as it itself handles the low-level features. Therefore, a framework saves a lot of time for developers, as they do not have to write code for an application right from scratch.

Why Use a Framework?

One of the most significant benefits of using a framework is that it significantly reduces the risk of errors in an application code. As the framework provides a basic structure for an application, you do not have to reinvent it.

The software development process is lengthy and complex as it involves various phases, like designing, coding, and testing. Programmers are responsible for the coding phase, as they need to focus on syntax, exceptions, garbage collections, etc.

A framework enables software developers to manage the software development process effectively. Below are some additional benefits of using a software framework:

  1. Using a framework means you are using pre-defined and pre-tested code. Therefore, the reliability of an application that you developed with that framework increases extensively.
  2. It helps you to utilize software design patterns correctly and develop better programming practices.
  3. You can avoid duplication and redundancy in your code.
  4. Some open-source frameworks enable users to contribute their programming skills to enhance the overall functionality and performance of the frameworks. Therefore, there is a scope of continuous improvement in a framework’s capabilities.
  5. A framework makes it possible for developers to test and debug the code effortlessly.

Software Framework vs Library

Many software developers interchangeably use the terms – framework and library. But the two are completely different terms. Also, some developers think that a framework is a collection of libraries. However, this assumption is also not true because all frameworks do not use libraries.

The primary difference between a library and a framework is the Inversion of Control. A framework calls the code, whereas the code calls a library. To understand it better, let us consider one example.

Let us say that our code uses a function from the curl library, a PHP library. In such a case, the PHP code calls that function present in curl. Therefore, the PHP code is a caller, and the library is the callee.

But if we use any PHP framework, like Symfony or Laravel, our code becomes callee, and a framework becomes caller, i.e., the framework we use to develop the code calls it. It is known as Inversion of Control (IoC).

Types of Frameworks

Want to develop a website, or a web application, or a mobile application, and looking for a relevant framework? Well, for every genre of software programming, you get a variety of frameworks. Therefore, it is essential to pick a framework that best fits your needs.

Below are some of the most trendy frameworks that you may need to know about:
