Package exports

Import path	What you get
rxjs-ai	Core primitives, AI controllers, and UI utilities — createStore, createCommandBus, createAsyncController, createChatController, createViewModel

import {
  createStore,
  createCommandBus,
  createAsyncController,
  createChatController,
  createViewModel,
} from 'rxjs-ai';

TypeScript

All types are exported directly from the main entry point. No separate @types package is needed.

import type {
  Store,
  StateUpdater,
  StatePatch,
  CommandBus,
  CommandMap,
  CommandEnvelope,
  AsyncController,
  AsyncState,
  AsyncStatus,
  ChatController,
  ChatModelAdapter,
  ChatModelRequest,
  ChatMessage,
  ChatState,
  ChatStatus,
  ChatRole,
  ChatChunk,
} from 'rxjs-ai';

Note

rxjs-ai is written in TypeScript and ships its own type declarations. Enabling strict mode in your tsconfig.json is recommended for the best experience.
