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
