Best Practices for Building a Modularized App

In this article, we’ll separate what the prescribed procedures for building a modular app are, above all, how about we start with a prologue to modular apps.

While parting application code into different modules isn’t really a new practice, it is turning into an increasingly well-known approach to put together cumbersome code.

All things considered, constructing a modular app requires aptitude and profound information on coding standards and their work processes, and important to keep some best practices in mind. 

An Introduction to Modular Applications

A measured application is an application made out of loosely coupled, useful units called modules, and these modules can be connected together to shape a bigger application.

Every module plays out a particular function or task, and although the entirety of the modules is independent of each other, they can communicate with one another without any problem. 

Building applications utilizing a more modular methodology keeps your code clean and coordinated and makes coding, testing, deployment, and maintenance simpler for both app development companies and businesses.

Modular development is likewise helpful in light of the fact that total modules can be reused for different applications, saving development teams important time and money.

Why Does Modularization Matter?

Efficient Program Development

Modularization makes development faster as more modest subprograms are easy to understand, compose, and plan than bigger ones.

The previous meaning of modules inputs and outputs makes it simpler for a developer to create and correct code to get the ideal output.

After the advancement of different modules, it is not difficult to incorporate and test them as a single unit.

Multiple Use of Subprograms

Modules are reusable on the grounds that it is not difficult to move or link them with different applications where they can satisfy comparable undertakings.

Therefore, modularized applications are simpler to oversee and scale, which thusly, saves money and limits the measure of time it takes to foster them.

Then again, monolithic programming makes it almost difficult to reuse existing code for another program since it’s often too hard to even consider finding and separate pieces of code from each other. 

Ease of Debugging and Modification

Modular code is simpler to troubleshoot than monolithic code since clear-cut program interfaces and issues are segregated into specific modules.

When the analyzer has recognized a faulty module, it becomes simpler for a developer to fix it.

Also, you can add new modules to a current application with certainty since you realize that it won’t influence different modules in the application. 

Since modules work independently of each other, it’s simpler to recognize code breaks.

As every module has its own capacity or assignment, if a specific capacity isn’t working, you can securely accept that there’s an isolated issue with the module liable for that function.

Then again, the dangers related to code like vulnerability and unpredictability increase with the length of your code.

Developing a Modular Application

The process of building a modular app begins with separating the different functionalities of your app into independent modules.

There are two methodologies that most associations use to do this—modularizing by feature and modularizing by layer—however, the one you should utilize truly relies upon your group and the task you’re working on. 

Modularize by Feature 

In this modularization approach, engineers break down code based on various app highlights, and it makes more modules as every module is characterizing a remarkable feature.

Later on, they coordinate those modules to make communication between them simpler and have an application that satisfies the required outcomes. 

Modularizing code by highlights has the following key qualities: 

  • It’s the best methodology when you have a large venture or are working with a lot of different team members
  • This methodology offers undeniable level modularization 
  • It upgrades the reusability of modules 
  • If not executed as expected, it can periodically make it more challenging for modules to communicate with each other 
  • This methodology has extremely severe development & deployment rules
  • Modularize by Layer

In this methodology, all the feature modules meet up under a single domain and have more adaptable guidelines. This methodology assists developers with utilizing separate modules for various features also. 

Modularizing code by layers has the following key qualities: 

  • This methodology prompts less isolated modules and makes the management simpler 
  • Just layers are reusable for multiple apps 
  • It has a similarity to monolithic applications

Best Practices for Developing Modular Applications

Modular application development requires proper comprehension of application features and modular architecture.

In case you are struggling to decide the most ideal approach to assemble a modular app for your venture, the following tips might be useful to you. 

Understand Project Details

Before you do anything else, ensure that you and everybody in your group have a strong comprehension of the project before you move into the development stage.

As modular design rotates around features and layers, having a superior comprehension of the various features of your app is vital to breaking projects into different modules.

It’s consistently simpler to code, test, and integrate various modules in the event that you begin on the right foot and break code into modules carefully. 

Keep Your Code Simple

Keep your code simple, and focus on each thing in turn prior to continuing on. Every snippet of code ought to play out a single assignment inside the scope of your project.

If you find yourself adding more tasks to your codebase without separating them into isolated modules, it very well might be an ideal opportunity to refactor it.

Use Abstract Interfaces

Abstract interfaces advance consistent communication between various fragments of code.

It’s significant that you come up with a theoretical interface for every module so it can cooperate with different modules through distinct interfaces as opposed to substantial executions.

This makes it simpler for developers in your team to alter or add new features without breaking existing functionality. 

DRY Coding

Keep your code DRY, or Don’t Repeat Yourself. DRY is a critical guideline in software development since it guarantees that no snippet of data is put away twice in various pieces of the program’s source code. 

  • This decreases excess which makes programs simpler to peruse and comprehend just as more viable over the long run 
  • To keep away from repetition in your codebase, use functions instead copying of code everywhere in your venture’s source documents  
  • Likewise, at whatever point conceivable use objects rather than primitive values or constants like strings or numbers while pronouncing factors for better reusability and extensibility in future updates/versions of your app. This makes your code more reusable and versatile! 
  • Use Names that are Easy to Understand

At the point when you are chipping away at various modules, it very well maybe not be difficult to stir up various module names, so furnish the entirety of your modules with clear and easy-to-understand names.

Thusly, any engineer looking at your code will know what it does just by looking at its name. 


Regardless of what you look like at it, modular app development strategies are rapidly turning into the fate of application development.

With a modular methodology, engineers don’t need to waste time each time they begin assembling an application.

Instead, they can reuse code that they or another person has effectively composed, giving them a leg up on the development process for each new venture.

Considering current application advancement principles, it is practically consistently beneficial to make reusable structure blocks of code.
