What is a Boilerplate Code & Why to use it?


What is a boilerplate code? In programming, boilerplate code signifies as the part of code that can be reused over and over again without modification. Sometimes programmers also coin it as boilerplate. In many legal contracts, including the ones we do in the IT industry, make rich use of boilerplates.

As an example, think of any legal agreement you’d get from a lawyer, the majority of it is a boilerplate — meaning it’s the same for everyone who gets it, with only a few lines changed in between.

Similarly, in programming, boilerplate code (or boilerplate) refers to sections of code that can be included in other parts of an existing or new program with little or no alteration.

Boilerplate codes are generally utilized for proficiency and to expand normalization in the programming structure. Also, the language of authoritative reports, for example, contracts, project outlines, and bond arrangements. To clearly understand the meaning of using boilerplate code, we will try to question and answer some topics regarding it in this article.

Why Use Boilerplate Code?

Many professionals prefer to create a collection of code assets that can be reused by them to accelerate development. How? Simply by referring to universal requirement patterns that are common in a niche. This not only helps them save time but also reduced their opportunity cost. How they use boilerplates? Simply by copying the code once used for a similar project and then start modifying it.

Further, there are some fundamental characteristics that a boilerplate must fulfill, this includes,

  • Follows industry coding standard
  • Has good and readable documentation
  • Code structure has a deeper abstraction level
  • Supports CLI tool (for rapid prototyping and setup)
  • Is scalable
  • Offers code splitting
  • East to test and can be integrated with necessary API modules
  • Has proper routing and navigational structure
  • Support for internationalization and localization
  • Server and client code for setup

Once met, you can straightaway start editing and altering the code to build your project. There are many tech giants who build their own boilerplate to use for respective future projects throughout time.

An example,

react-boilerplate — :fire: A highly scalable, offline-first foundation with the best developer experience and a focus…github.com

Boilerplate Code in Smaller Projects (or Scaffolding)

You can also call these as “started kits” or “scaffolding”. Generally, these are used by novice developers or new early adopters. This practice primarily focuses on creating only necessary elements for a new project (also known as rapid prototyping). These are also quite favored by early-stage tech startups as these require less functionality and are not scalable over time.

This code explains the most basic example of boilerplate code. We can see “head”, “intro”, and “body text specifications” already mentioned in the boilerplate code. We just need to punch in the numeric values and few function names to complete this small task.

Furthermore, the code structure does not offer wide coverage and doesn’t include any deeper abstraction layer as you just need core features at such an initial stage.

A good example would be Facebook’s create-react-app boilerplate:

create-react-app — Create React apps with no build configuration.github.com

Difference Between Boilerplate and Template

In a broad view, boilerplate code is something that you copy and paste and just add as a part to a document. You can think of it as contracts where the language is used and reused, spelling out things like conditions, statements, etc.

On the contrary, a template is a model or pattern used to create new objects. A template is adjusted for a specific use-case and employed generally at the foundation of the program.

Further, both templates and boilerplates can make your program inflated and artificial if used unwisely.

Benefits of Boilerplate Code

Some of the most important benefits of boilerplate code are:

1. Shorter Learning Cycle: If your product utilizes the standard boilerplate code as a base then there will be no additional learning time for new designers who have taken a shot at a similar boilerplate.

2. Increase Early Development: The principle benefit of using boilerplate code is to decrease your underlying programming time by reusing core model characteristics.

3. Less Complexity: It additionally deals with unpredictability from your code and gives you perhaps cleaner and more readable code. A new designer may find it easy to understand in a shorter time duration.

When Is The Boilerplate Code Used

1. Your necessities are clear

If your product prerequisites are clear and those are coordinating with the particular boilerplate code included, then it is a great idea to go with it.

2. Your prerequisites are not satisfactory

For example, the total extent of the product is not clear in the first place. The explanation not to pick boilerplate is, there may be a few cases later on, which may not support this boilerplate, or it limits with explicit methodology or UI.


In conclusion, we can sum up that boilerplate code is a frame for your project. You can use it according to your requirement and conditions. In addition, when you are aware that many similar projects are piling on your table, a boilerplate can be a massive time saver.
