A New Paradigm for Large-Scale Frontend Architecture - Part 2. Module Federation PoC

To address code duplication, high coupling, and deployment bottlenecks that occur in large-scale services, the adoption of Module Federation (MF) was reviewed. MF is an architectural pattern that allows code and resources to be shared at runtime between JavaScript applications.

Unlike the existing build-integration approach, MF enables each micro frontend to be deployed independently through runtime integration. This allows changes to a specific module to be reflected in real time without redeploying other applications.

Key concepts include the Host, which loads other apps, the Remote, which exposes modules, and Shared Dependencies (Singleton), which prevent duplicate loading of dependencies. Through this PoC, Oliveyoung reviewed an MF configuration approach based on Next.js in order to secure service scalability.
