The article points out that the frontend domain has long faced the monolithic application dilemma—a problem that the backend has already solved—characterized by large codebases, coupled deployments, and high change risks. The rise of micro frontends is not merely a technical trend but an inevitable result of sociotechnical evolution, aiming to accelerate value delivery by integrating people, processes, and architecture around common goals. It emphasizes that micro frontends represent a new paradigm for organizing work, rather than just a technical pattern, clarifying their core lies in encapsulating responsibilities and maximizing independence by differentiating micro frontends from components. The article details applicable scenarios for micro frontends, particularly for solving organizational-level delivery bottlenecks and scaling limitations. For existing systems, it proposes an iterative mindset and the Strangler Fig Pattern, emphasizing incremental migration via edge routing and planning an end-to-end first micro frontend as an experiment. Concurrently, the article discusses cross-cutting concerns like routing, authentication, and state management, encouraging embracing sensible duplication to improve speed and flexibility. Finally, this paper emphasizes that the frontend can lead the modernization process, achieving gradual modernization at “human speed” rather than a “big bang,” to enable continuous, secure, and targeted evolution.
