Toward Bundler-Independent Module Federations: Enabling Typed Micro-Frontend Architectures

Modern web applications demand scalable and modular architectures, driving the adoption of micro-frontends. This paper introduces Bundler-Independent Module Federation (BIMF) as a New Idea, enabling runtime module loading without relying on traditional bundlers, thereby enhancing flexibility and team collaboration. This paper presents the initial implementation of BIMF, emphasizing benefits such as shared dependency management and modular performance optimization. We address key challenges, including debugging, observability, and performance bottlenecks, and propose solutions such as distributed tracing, server-side rendering, and intelligent prefetching. Future work will focus on evaluating observability tools, improving developer experience, and implementing performance optimizations to fully realize BIMF's potential in micro-frontend architectures.
