Micro-Frontends: Decoupling Monolithic React Apps

As our enterprise dashboard grew to encompass complex analytics, billing systems, and API key management, our Webpack build times skyrocketed. The monolithic React repository became a bottleneck for continuous deployment.

Module Federation in Action

We transitioned to a Micro-Frontend architecture utilizing Webpack Module Federation. This allowed us to divide our dashboard into distinct, independently deployable applications. The billing team can now deploy UI updates, test them, and ship them without ever communicating with the analytics team.

Seamless User Experience

Despite being developed in separate repositories, the micro-frontends merge seamlessly in the user's browser at runtime via dynamic imports. The user perceives a single, unified Single Page Application, while our engineering teams enjoy the velocity of decoupled deployments.
