Software Framework vs Library

In the programming world, "framework" and "library" are a set of classes, modules, and/or code (depending on the programming language) that can be used in your applications.

 In general, the differential feature is a matter of control - frameworks determine how your project will be structured, while libraries are building blocks that can be used anywhere.

What is Framework?

A framework is a platform for software programs. It provides a foundation on which software developers can build programs for a specific platform. According to the example, an outline may include functions and classes. Which can be used to process the inputs, handle the hardware devices, and interact with the system applications. The framework streamlines the development process because developers do not need to reinforce the wheel every time they develop a new program.

A framework is like an application programming interface (API), although technically a frame includes an API. It assists as a basis for programming while providing access to elements supported by an API framework. Sometimes an outline may also include a compiler, code library, and other programs used in the software development process. Different types of software frameworks exist.

Why do we use Framework?

A framework is one of the tools available to help you develop faster and better!

The framework gives you the result that you are developing an application that is fully integrated with business rules, which is structured and is both maintainable and upgradable.

Increasingly, as it enables developers to save time by reusing generic modules to focus on other areas. Without, however, being tied to the frame.

• A framework is not an absolute requirement, but it is beneficial.

• A framework is a pledge of stability of assets, upgrades, and applications at affordable costs.

• Software developed using a framework operates with exchange rules.

Types of Framework

• Server-side

• Client-side

Server-side Web Application Framework

Although the front end has evolved, it is the first and most important task to display without app logic and an interface. That is why server-side frameworks are necessary.

With the most popular MVC-based server-side web frameworks are:

• Django (Python)

• Symfony (PHP)

• Express (Node.js/JavaScript)

• ASP.NET (C#)

• Ruby on Rails (Ruby)

Using both of these server-side web application frameworks, you allow it to handle HTTP requests, database management, and handling in addition to URL mapping. But instead think about using a client-side framework, introducing additional user-engaging features and accountability.

Client-side Web Application Framework

The client-side framework is usually a JavaScript library and runs in a Web browser, such as React, Angular and etc.

Every client-side framework is different from the other in its use and its function. Some of the most popular client-side frameworks:

• React.js

• Backbone.

• Bootstrap.

• Semantic-UI.

• Angular.js

With a server-side framework, your decision mainly depends on the language you feel comfortable developing. Here you should take into account the specific skills of various client-side frameworks. Since they differ in the area of ​​confirmed functionality, look for something that meets the needs of your future web app.

What Is Library?

A library is a set of class definitions. The reason behind is code reuse, i.e., get the code which is already written by other programmers. Methods and classes define operations. There are a few libraries of mathematics that may let the function is called by a developer without redo the implementation of an algorithm works. Libraries precompiled for many reasons. Since libraries change, they don't have to recompile. It would be a consumption of time to recompile the library each time you wrote.

Sometimes the library can also be a set of implementations of behavior, written concerning a language, with a well-defined interface where the behavior is invoked. As an example, people who wish to write a higher-level program can use a library to generate system calls rather than implementing those system calls over and over again. Additionally, multiple applications provide for reuse of the behavior. A program invokes the behavior using a mechanism of this language. By way of instance, in a simple imperative language like C, the behavior in a library is invoked by using C ordinary function-call.

Types of Library    

• Static libraries

• Dynamic libraries 

What is a Static Library?

A static library (also referred to as archive) includes routines that are compiled and linked directly to your program. When you compile a program, which uses a static library, the performance of all the static libraries you use becomes a part of your executable. On Windows libraries have a .lib extension, whereas on Linux libraries have an. 1 benefit of static libraries is that you just need to distribute the executable in order for users to run your application.

Windows libraries have a .lib extension, while Linux libraries have a. 1 advantage of static libraries is that you need to distribute executables for users to run your application.

 Since the library becomes part of your application, this helps to ensure that the perfect version of the library is always used together with your program. Additionally, because static libraries become a part of your application, you can use them just like the performance you have written for your application. On the downside, because a copy of the library becomes a part, this can cause lots of space. Static libraries also can't be updated easily -- to upgrade the library, the whole executable has to be replaced.

What is a Dynamic Library?

A dynamic library (also known as a shared library) includes patterns that load into your program at run time. When you compile a program that uses the library, the library does not become part of your executable - it remains as a unit. On Windows, a dynamic library typically has a .dll (dynamic link library) extension, while on Linux, a dynamic library typically has a .so (shared object) extension.

One advantage of dynamic libraries is that a single copy, which saves space can be shared by programs. Maybe a bigger advantage is that the library can be updated without replacing the executables that use it all.

Conclusion

The main difference between a library and a framework is the "inverse of control". When you call a method from a library, you are in control. But with a framework, the control is reversible: the framework calls you.

Overall, the framework is more opinionated and libraries are more flexible. Both patterns of abstraction have their place in the world of programming.
