Decoupled, Not Disconnected: State and Sync in Micro-Frontends

Abstract

As teams and apps grow, micro-frontends offer a way to scale — but managing state and communication across modules gets tricky. In this talk, I’ll explore how to structure micro-frontends in React and Next.js, how to manage different types of state, and how to keep everything in sync across backends, auth, and storage. Whether you’re considering micro-frontends or already working with them, this talk will help you avoid the pain points and build modular systems that still feel cohesive.
