A boilerplate code is simply something in textual form that can be used repeatedly by making only a few changes or no changes.
What is boilerplate code?
- In computer programming, a boilerplate code (often called a boilerplate) is a piece of code that can be used by many people with only a tiny change or sometimes no changes at all.
- Here is always a need to do more productive tasks in the minimum possible time in the corporate world.
- It has been a standard for many businesses to use boilerplate code for specific tasks to cut the production time.
- Suppose you are a C++ programmer and use any IDE (Integrated Development Environment). It delivers you with a chunk of standard code that you can edit as per your requirement.
E.g., the following code in c++ can be considered boilerplate and would be the same for probably all the c++ programs.
Why use boilerplates?
The main advantage of using boilerplates is to reduce the time consumed in software development by reusing primary things. Thus accelerating development.
Here the code written is comparatively cleaner and easy to debug.
Examples of boilerplates:
- In HTML
- The HTML is a markup language used to build the basic structure of a web page.
- In the HTML, the below-given boilerplate is often used in probably all of the web pages.
- In object-oriented programming:
And also, in object-oriented programming, a class is a group of methods (member functions) and variables (data members). These methods can be considered boilerplates. Even different styles can have other getter and setter methods, but they are the same. E.g., in the below-given code, everything is boilerplate except the declarations for the car.
The boilerplate concept in Frameworks:
- Each programming language has some frameworks to do all the heavy lifting with ease. Similar PHP has CodeIgniter, Laravel, CakePHP.
- Let’s revenue the example of CodeIgniter, which is an overall MVC framework writing in PHP.
Here CodeIgniter has a prebuild structure for all essential modules, with the controller and the models.
- Some programming language contains declarative statements that cannot be considering a necessary part of the logical code but are still including at the start of the code.
- Let’s consume a look at the below statements written at the beginning of a C++ program.
- The iostream is a header file that needs to be including at the start of a program to use the standard statements to take input from a user and display the output to the screen.
- All of the messages that have the # symbol at the starting are calling preprocessor directives.
- A preprocessor directive(or preprocessor in short) says the compiler processes all the statements that start with #.
The comprise statement can be using in one of the following ways:
Include: This is a directive that would consist of a predefined header file.
Have “file-name”: This is a directive that would include a user-defined header file.
The using namespace std statement means that something is present in the declared scope. It is to use the standard accounts without the need to prefix std. For example, std::cout.
