falsandtru/clientchannel

ClientChannel is a TypeScript library that provides a unified, layered API for cross-tab communication and persistent data synchronization in the browser. It abstracts the complexities of IndexedDB, Web Storage, and BroadcastChannel into consistent interfaces for storage, ownership, and messaging. The system manages state transitions, data validation, and resource lifecycle, enabling reliable multi-tab data sharing and local persistence.
