A boilerplate code is a textual form that can be used repeatedly with only a few changes or no changes.

The most repetitive examples of each other are legal agreements, such as privacy policy, terms and conditions. Here you may be provided with a multi-page contract, but most of your part is standard.

What is boilerplate code?

In computer programming, a boilerplate code (often called boilerplate) is a piece of code that can be used by many people with only a tiny change or sometimes no change at all.

  • Here the need always arises to do more productive tasks in the shortest possible time in the corporate world.
  • Therefore, it has been a standard for many companies to use boilerplate code for specific tasks to reduce production time.
  • Suppose you are a C++ programmer and use any IDE (Integrated Development Environment). It provides you with a standard code snippet that you can edit to suit your needs.
  • For example, the following C++ code can be considered boilerplate and is likely to be the same for all C++ programs.

Why use replays?

The main advantage of using iterations is to reduce the time spent on software development by reusing primary things.

Thus accelerating development.

Here the written code is comparatively cleaner and easier to debug.

Examples of repeats:

  • In HTML
  • HTML is a markup language used to build the basic structure of a web page.
  • In HTML, the standard text below is often used on all web pages.

In object-oriented programming:

  • However, in object-oriented programming, a class is a group of methods (member functions) and variables (data members).
  • These methods can be considered repetitive. Different styles may have other getter and setter methods, but they are the same.
  • For example, everything is boilerplate except for the car declarations in the following code.

The boilerplate concept in Frameworks:

  • Every programming language has some frameworks to ease all the heavy lifting. Python has Django and flask, JavaScript has Express JS, Angular JS, Ruby has Ruby on Rails, etc.
  • For example, similar PHP has CodeIgniter, Laravel, CakePHP.
  • Let’s look at the example of CodeIgniter, which is a general MVC framework writting in PHP.
    Here CodeIgniter has a precompiled structure for all the essential modules, with controller and models.


Some programming languages contain declarative statements that cannot be considering a necessary part of the logical code but are still including at the beginning of the code.

  • For example, let’s look at the following declarations written at the beginning of a C++ program.
  • The stream is a header file that must be including at the beginning of a program to use the formal statements to input a user and display the output on the screen.
  • All messages with the # symbol at the beginning are calling preprocessor directives. A preprocessor directive (or preprocessor for short) says that the compiler processes all statements that start with #.

The comprehension statement can be using in one of the following ways:

Include: This directive would consist of a predefined header file.

  • Have “filename”: This directive would consist of a user-defined header file.
  • The using namespace std statement means something is present in the declared scope. Therefore, using the standard accounts without the std prefix is a question—for example, standard::cout.
