How Does Micro Frontend Architecture Work?

In the ever-changing realm of web development, the quest for constructing scalable and easily maintainable applications remains a perpetual hurdle. Enter the micro frontend architecture, an innovative solution to this enduring challenge. This methodology empowers development teams to dissect colossal frontend applications into smaller, more wieldy components.

In the following discussion, we shall delve into the core principles and inner workings of micro frontend architecture to gain a comprehensive understanding of its mechanics.

Understanding Micro Frontend Architecture

Micro frontend architecture is an extension of the microservices concept, but it’s applied to the frontend layer of web applications. It promotes the division of a monolithic frontend into smaller, self-contained modules, or micro frontends. These modules can be developed, deployed, and maintained independently. Each micro frontend represents a specific piece of the user interface and is responsible for its own functionality and user experience.

How Does Micro Frontend Architecture Work?

Decomposition: The first step in implementing micro frontend architecture is breaking down the monolithic frontend into smaller, self-contained modules. These modules can be organized by functionality, feature, or team ownership. The goal is to isolate different parts of the application, making it easier to develop, test, and deploy each independently.

Independent Development: Micro frontend teams can work on their respective modules without interfering with the work of other teams. This separation allows for more focused development, enabling teams to choose the technologies and frameworks that best suit their specific requirements.

Standardized Interfaces: To ensure seamless integration, it’s essential to define standardized interfaces and communication protocols between micro frontends. This can include specifying how data is passed between modules and how they interact with shared components or services.

Composition: At runtime, these micro frontends are composed to create the complete user interface. This can be achieved in various ways, such as server-side composition, client-side composition, or a combination of both.

Deployment: Each micro frontend can be deployed independently. This means that changes or updates to one module won’t necessitate deploying the entire application. It reduces the risk of deployment failures and allows for quicker iteration.

Versioning: Micro frontend architecture often includes a versioning strategy. This ensures that different versions of micro frontends can coexist peacefully. Users can interact with the latest versions of some modules while older versions are gradually phased out.

Routing and Navigation: Micro frontends must work together cohesively in terms of routing and navigation. This requires careful planning to ensure that users can seamlessly navigate between different parts of the application.

Benefits of Micro Frontend Architecture

Scalability: Micro frontend architecture makes it easier to scale development efforts by allowing teams to work on specific modules independently.

Reusability: Shared components, libraries, and services can be reused across different micro frontends, reducing redundancy and saving development time.

Independent Deployment: Teams can deploy their micro frontends independently, reducing the risk of deployment-related issues and allowing for quicker updates.

Technology Flexibility: Teams can select the best technology stack for their specific micro frontend, enabling them to use the right tools for the job.

Improved Maintenance: Isolating parts of the application simplifies maintenance, debugging, and troubleshooting, making it more manageable for development teams.

Challenges of Micro Frontend Architecture

While micro frontend architecture offers numerous benefits, it also comes with some challenges:

Coordination: Teams need to coordinate their efforts to ensure that micro frontends work seamlessly together.

Communication: Effective communication and interface design are crucial to prevent integration issues.

Complexity: Managing multiple micro frontends and their interactions can be complex and require careful planning.

Initial Setup: Implementing micro frontend architecture may require some initial overhead to set up the infrastructure and development workflows.


The advent of micro frontend architecture signifies a significant advancement in the realm of web development, providing a promising solution to the complexities associated with monolithic frontend applications. This innovative approach allows for the segmentation of applications into smaller, self-contained modules, and offers the benefits of autonomous development, standardized interfaces, and independent deployment.

If you’re contemplating the adoption of micro frontend architecture and are seeking seasoned professionals to realize your vision, we strongly recommend to hire Angular developers. Angular, equipped with its formidable array of features and tools, stands as an excellent choice for constructing resilient micro frontends. Employing skilled Angular developers as part of your team will guarantee that your micro frontend architecture is designed and upheld to its fullest potential, thereby introducing efficiency, scalability, and ease of maintenance to your web applications.
