Micro-frontends are an architectural style where a large, complex front-end application is decomposed into smaller, independent, and autonomous applications. This approach mirrors the microservices concept on the backend. The primary advantage for large enterprises is enabling independent deployment and technology upgrades for different parts of the UI, drastically improving team autonomy and reducing the risk associated with large-scale releases. While they increase complexity in initial setup and require careful state management across boundaries, the benefits in maintainability and scaling for large teams often outweigh the challenges.
