The prospect of web development is constantly in flux. While once monolithic applications were the only players, changing trends and technologies procreated micro frontends. They foster a more modular approach and implement diverse architectural styles to help businesses build complex front-end applications.

This blog discusses the power of micro frontend frameworks. It also talks about how developers can leverage it to exceptional custom software development services. So, keep on reading! 

What are micro frontends?

Micro frontend architectures have brought in a paradigm shift in frontend development.  Instead of a monolithic approach, where everything was compiled and developed all at once, micro-frontends offer a more flexible approach. 

Here are some key characteristics of well-designed micro frontends:

  • Single responsibility principle (SRP): Each micro frontend is assigned a clear and distinct responsibility, promoting focused development and improved maintainability.
  • Loose coupling: Micro frontends interact through well-defined interfaces, minimizing dependencies and enabling independent development across teams.
  • High cohesion: Functionality within a micro frontend is closely related, improving code readability and maintainability.

Types of micro frontend architectures

The implementation of micro frontends can be achieved through various architectural patterns.  Here are some widely used approaches:


This approach houses all micro frontend projects within a single codebase. While seemingly contradicting the philosophy of microservices, it offers unique advantages:

  • Centralized dependencies: All micro frontends share the same dependency management system, simplifying version control and updates.
  • Enhanced collaboration: Developers have full visibility into all projects, fostering knowledge sharing and collaboration.
  • Consistent tooling: Standardized tools and configurations can be applied uniformly across all micro frontends.

However, there are considerations:

  • Potential complexity:  As the number of micro frontends grows, managing a large mono repository can become cumbersome in custom software development.
  • Build and deployment challenges: Ensuring efficient builds and deployments for all projects within the single codebase can be complex.


In contrast, the multi-repository approach isolates each micro frontend project in its own repository. This isolation provides several benefits:

  • Project isolation: Projects are independent, minimizing the risk of conflicts and dependency issues.
  • Decentralized development: Teams have complete autonomy over their micro frontend projects, allowing for diverse technology stacks and development processes.
  • Scalability: Adding new micro frontends or teams becomes easier as the application scales.

However, challenges exist:

  • Integration complexity: Coordinating the integration of multiple repositories can be more intricate than managing a single one.
  • Dependency versioning: Maintaining compatibility of dependencies across separate repositories requires careful version management.


The meta-repository approach seeks a middle ground, balancing the benefits of the mono amd multi-repository micro-frontends. It utilizes multiple repositories for individual micro frontends but integrates them into a central repository:

  • Flexibility: Teams maintain autonomy by working on their micro frontends in separate repositories.
  • Integration: The central repository facilitates the integration of individual micro frontends, creating a unified application.

However, there are considerations:

  • Complexity: Balancing the need for integration with individual repository autonomy can introduce complexity.
  • Coordination: Teams might still need to coordinate on common integration points and standards.

Benefits of using micro frontend in custom software development

Below are the benefits of micro frontends that top software development firms can leverage:

Modular codebase

Micro frontends decompose the codebase into smaller, well-defined modules. This modularity allows individual teams to focus on specific functionalities without needing to understand the entire codebase. This streamlines maintenance and mitigates the risk of introducing regressions during updates.

Independent scaling

Each micro frontend scales independently based on its specific load requirements. This enables efficient resource allocation. High-traffic functionalities can be scaled up without impacting the performance of less demanding sections of the application.

Simplified code reviews

Smaller codebases in micro frontends lead to faster and more efficient code reviews. This promotes code quality and reduces overall development time.

Independent development

Micro frontend architectures enable different teams to develop independent functionalities. Teams can simultaneously work on their assigned features, significantly accelerating development cycles. This allows for faster iteration and quicker delivery of new features to users.

Improved collaboration

Micro frontends promote better collaboration between teams with clear ownership and responsibility boundaries. This facilitates communication and avoids conflicts that can arise in monolithic development.

Team ownership

A dedicated team can own and maintain each micro frontend in custom software development. This empowers teams to make independent decisions about the technology stack and development approach best suited for their specific functionality.

Improved team morale

Increased ownership and autonomy foster a sense of ownership within development teams. This can lead to higher team morale, improved engagement, and a more productive development environment.

Mixed technology stacks

Micro frontends allow developers to choose the best technology stack for each functionality. This enables the use of cutting-edge technologies like React, Vue.js, or Angular for specific functionalities.

Tech stack agnosticism

Development teams are not limited to a single framework or library. They can choose the technology that best suits the specific needs of the micro frontend they’re developing. This fosters innovation and experimentation within the development teams.

Implementation considerations for micro frontends

Here are the implementation considerations for micro frontends in custom software development:

Custom events

Micro frontends can publish and subscribe to custom events broadcasted through the browser’s event system. This lightweight approach enables loose coupling and facilitates communication for simple interactions.

Shared state management

Complex scenarios might require a shared state management solution like Redux or MobX. This allows micro frontends to maintain a consistent global state but introduces additional complexity to the architecture.

API gateways

Micro frontends can interact with backend services through a centralized API gateway. This approach simplifies communication and enforces access control policies for a secure and well-defined interface.

Message buses

Message buses like Apache Kafka or RabbitMQ provide asynchronous communication between micro frontends. This further decouples communication, allowing micro frontends to send and receive messages without knowing who else is participating in the conversation.

Scalability and performance consideration of micro frontends

Check out the scalability and performance considerations of micro frontends in custom software development:

Horizontal scaling

Individual micro frontends can be scaled independently based on their load. This helps in efficient resource allocation and better responsiveness under high traffic.

Efficient data fetching

Micro frontends should implement strategies for fetching data efficiently. Techniques like lazy loading and content delivery networks (CDNs) can minimize data transfer and improve initial load times.

Distributed architectures

Distributed architectures can benefit complex applications. Micro frontends can be hosted across different servers or cloud environments, improving overall application performance.

Testing strategies and security best practices

  • Unit testing: Individual micro frontend components should be thoroughly unit tested to ensure their functionality in isolation.
  • Integration testing: Integration tests verify how micro frontends interact with each other and backend services. Tools like mocking can simulate dependencies during testing.
  • End-to-end testing: Tests assess the overall user experience by simulating user interactions across different micro frontends.
  • Contract testing: Contract testing ensures compatibility between micro frontends and backend APIs. This helps identify any integration issues before deployment.
  • Isolation: Micro frontends should be sandboxed to prevent unauthorized access or malicious scripts from impacting other parts of the application.
  • Authentication/authorization: Implement strong authentication and authorization mechanisms to control access to micro frontends and backend APIs.
  • Secure communication: Ensure all communication between micro frontends and backend services uses secure protocols like HTTPS to encrypt data transmission.
  • Input validation and sanitization: Validate and sanitize all user input to control potential security weaknesses, such as cross-site scripting (XSS) or SQL injection.

When to use a micro-frontend architecture?

Micro-frontends can be used in custom software development in the following ways.

Large, feature-rich applications

As applications balloon in functionality, monolithic codebases become unwieldy and difficult to manage. Micro frontends decompose the frontend into smaller, self-contained units, making maintenance and updates significantly easier for large development teams.

Diverse technology stacks

Micro frontends empower teams to choose the best technology stack for each specific functionality. This allows leveraging cutting-edge frameworks like React or Vue.js for specific features while integrating seamlessly with existing legacy codebases.

Independent development and faster releases:

Micro frontends enable separate teams to develop concurrent functionalities. This fosters faster development cycles and quicker time to market for new features. Teams can work independently without needing to wait for updates on other functionalities within the monolithic codebase.

Evolving business requirements

Micro frontends offer superior adaptability to changing business needs. New features or functionalities can be introduced as independent micro frontends, seamlessly integrating with the existing application. This helps with a more modular approach to evolving business requirements.

Team autonomy and improved morale

Micro frontends empower development teams with ownership over specific functionalities. Teams can choose their preferred technology stack and development processes, fostering a sense of autonomy and higher morale. This fosters a more engaged and productive development environment.


This was all-inclusive information on micro frontends. The best custom software development company can leverage the power of micro frontends to manage complex and dynamic web applications. However, it is essential to remember that despite all the benefits, these have some limitations. Thus, while in some situations they increase the application’s efficiency, they are not one-size-fits-all solutions.
