Multiple frontend architecture involves supporting diverse user interfaces across platforms like web, mobile, and IoT devices, each potentially using different frameworks. This approach presents challenges in maintaining consistent operations across various technical stacks such as React, Vue, and React Native, leading to complexity that can be exacerbated by trends like micro-frontends. While micro-frontends allow independent development and deployment of application segments, they can also result in increased maintenance demands if not managed properly. A practical approach to managing multiple frontends emphasizes an API-first strategy that ensures consistent data communication across platforms and module federation for sharing code without frequent rebuilding. By aligning frontend boundaries with business logic and employing thoughtful dependency management, teams can optimize performance without unnecessary complexity. Security and integration are key considerations, requiring consistent authentication and well-defined interaction contracts between frontends to maintain a cohesive system. The ultimate goal is to create an architecture that is understandable, maintainable, and scalable, enabling teams to focus on feature development rather than constant adaptation to new frameworks.
