@octoryn/ui-core

Framework-neutral message types, stream codec and reducer for Octoryn UI SDKs.

import {
  decodeUIStream,
  reduceUIStream,
  type UIStreamState,
} from "@octoryn/ui-core";

let state: UIStreamState = { messages: [] };
for await (const event of decodeUIStream(response.body!)) {
  state = reduceUIStream(state, event);
}

The protocol is plain SSE plus JSON and is shared by browser, iOS and Android clients.

OctorynChatController, OctorynCompletionController and OctorynObjectController provide the shared framework-neutral state machines used by the React, Vue, Svelte and Angular packages. They own cancellation, error mapping, governance metadata and message-part reduction. Chat supports edit, regenerate and cursor-aware resume through UITransport; smoothTextStream is a composable normalized stream transform. Run npm run build && node examples/advanced.mjs for the content-free recovery and structured-object example.
