What Are Micro-Frontends?

The Core Concept

Micro-frontends extend the microservices concept to frontend development. Instead of a monolithic frontend application, you build multiple smaller, independent applications that work together as a cohesive user experience.

Key principles :

Technology agnostic : Each micro-frontend can use different frameworks

Independent deployment : Deploy parts of your app independently

Team autonomy : Different teams own different parts of the application

Isolated development : Develop and test in isolation

When Micro-Frontends Make Sense
