Microfrontends

Microfrontends are  an architectural pattern where a web application's frontend is broken down into smaller, independent, and self-contained modules , similar to how  microservices  work on the backend.  Each module can be developed, tested, and deployed independently by different teams, often using different technologies, to build a single, seamless user interface.  This approach enhances scalability, flexibility, and the ability for teams to work more autonomously.   

 

 

 

 

 

 

 

 

 

 Key concepts 

 

 

 

 

 

 

 

 

 Independent modules :  

 The UI is split into smaller, manageable parts, like a product listing, shopping cart, or user profile, each responsible for its own functionality.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Independent development :  

 Different teams can work on different microfrontends simultaneously without blocking each other.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Technology flexibility :  

 While it's often practical to stick to a single framework, the architecture allows for different technologies to be used in different parts of the application if needed.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Independent deployment :  

 Each microfrontend can have its own repository, build process, and CI/CD pipeline, allowing for faster and more frequent updates.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Communication :  

 Microfrontends communicate with each other and with the backend through well-defined APIs.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Benefits 

 

 

 

 

 

 

 

 

 Increased agility :  

 Teams can deliver features and updates more quickly and frequently.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Scalability :  

 It is easier to scale the development of large and complex applications by dividing the work.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Resilience :  

 An issue in one microfrontend is less likely to bring down the entire application.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Reduced coupling :  

 It minimizes the code shared between different functional areas of the application.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Drawbacks 

 

 

 

 

 

 

 

 

 Increased complexity :  

 Managing multiple repositories, build pipelines, and deployments can increase the overall complexity of the project.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Higher costs :  

 There can be increased costs associated with the overhead of managing more individual projects.   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Potential for excessive coupling :  

 Without strong governance, it can lead to an unmanageable "splatter" of versions and dependencies
