dsh-ui-container

When building DeepSeek Harness browser plugins, developers often struggle with efficiently managing UI states and cross-process communication, especially when needing remote interactions without transmitting large DOM or component trees.

dsh-ui-container serves as a reusable container that offers named UI surfaces, document providers, and an efficient remote protocol. It supports cross-process connections via MessagePort or network connections via WebSocket, intelligently transmitting only document snapshots and change notifications instead of the full rendering tree, which significantly optimizes performance.

This plugin is ideal for developers aiming to construct complex, scalable, and reusable frontend architectures for browser extensions. It is particularly suited for teams looking to decouple rendering logic from business logic or integrate multiple services within a single extension context using the React ecosystem.
