microfrontend-architecture

Decompose a monolithic frontend into micro-frontends by aligning UI slices with Bounded Contexts for team autonomy, then using runtime Module Federation to compose fragments. This enables independent build, test, and deploy cycles without coordinated releases.

Runtime Module Federation is a mechanism that maintains SPA ergonomics while allowing independent deployment of frontend fragments. It enables a shell application to dynamically load and compose separately deployed UI slices at runtime.

Split your frontend into independent fragments when operating in multi-team, multi-product environments requiring decoupled release cadences and vertical domain alignment. This approach solves bottlenecks caused by coordinated monolithic release cycles.

Enforce shell-to-fragment contracts by applying a versioned framework that manages strict singleton dependencies and independent CI/CD pipelines. This ensures decoupled fragments maintain compatibility with the shell during deployment.

Yes, microfrontend architectures using Module Federation require strict singleton dependency management to prevent runtime conflicts. This ensures shared libraries are loaded once, maintaining fragment isolation and shell stability.

A limitation of Module Federation is the overhead of enforcing versioned shell-to-fragment contracts and managing strict singleton dependencies. It is unnecessary if your application lacks multi-team development or decoupled release cadence requirements.
