A New Paradigm for Large-Scale Frontend Architecture - Part 3. Micro Frontends Using Nx

As the codebase of large-scale services expands, the importance of micro frontend (MFE) architecture, which manages dependencies between modules and enables independent development and deployment, is growing.

OliveYoung reviewed Nx, a monorepo tool, for efficient MFE construction. Nx provides an environment optimized for managing large-scale projects through Computation Caching, the Affected feature that builds only changed modules, and the Graph feature that helps visualize dependencies.

This article introduces the process of implementing MFE in two ways using Nx.

• Build-time integration approach: A method where multiple modules are included in a single main app and ultimately built and deployed together as one bundle
• Runtime integration approach: A method that leverages Module Federation technology to integrate different apps into one at runtime

Compared to Turborepo, Nx offers dependency visualization and a rich plugin ecosystem, making it advantageous for gradually introducing and scaling complex architectures.
