Practical guidance between vertical and horizontal micro-frontends

Micro-frontends apply the principles of microservices to the frontend, allowing large applications to be divided into smaller, independently developed and deployed modules. They enhance scalability, flexibility, and team autonomy by breaking down monolithic frontends into manageable components. This approach introduces challenges, such as complex shared state management and the need for seamless integration and coordination among different teams. Advanced coding strategies can address these challenges, including state management solutions like Redux or the Context API and event-driven architectures for cross-micro-frontend communication. Vertical micro-frontends emphasize client-side composition for single-page applications, while horizontal micro-frontends focus on loading multiple components into a single view for high-traffic sites. Techniques like server-side and edge-side composition optimize performance and content delivery, while event-driven architectures facilitate communication without tightly coupling components. Despite the complexity, with adequate planning and coordination, micro-frontends can deliver scalable, maintainable, and cohesive user experiences.
