Micro-frontends and JavaScript State Management
State management
A sync’d state is essential to preserve a good user experience across decoupled frontends. You can refer to the pros and cons page, to understand why state is very important.
Event-driven patterns and middleware can help propagate state across decoupled components, even when independently deployed, or deployed hrizontally at scale.
Pub/Sub
A publication and subscription bus is a a good strategy to manage state, and it can be implemented at an infrastructure level, with serverless functions, or client-side, leveraging the browser’s addEventListener API and windows.postMessage(), to communicate events across frontend components.
