Instead of raw token streams, the system uses typed events organized by channels (messages, tools, state, lifecycle) and namespaces (which node in the agent tree emitted them). Developers subscribe to typed projections rather than parsing raw chunks, enabling scoped subscriptions so a UI component only receives data it renders. The model supports subagent visibility, multimodal outputs (text, images, audio, video), custom application-defined channels, and resilient reconnection to long-running threads. Framework SDKs for React, Vue, Svelte, and Angular expose the same concepts via hooks, composables, and signals. A streaming cookbook with Python and TypeScript examples accompanies the release. ## Full article daily.dev links to this article rather than hosting it.
