react-call@2.0.0-next.6

Minor Changes

• 2e72674: New react-call/host subpath export — an imperative mount(element, options?) helper for environments that render multiple isolated React subtrees in parallel for previewing (Storybook autodocs page, Ladle, Histoire, react-cosmos). Mounts a single shared Root in a body-level <div data-react-call-host> via its own createRoot, sidestepping the multi-root call-time throw that decorator-per-story patterns otherwise hit.

  // .storybook/preview.tsx
  import { mount } from "react-call/host";
  import { Confirm } from "../src/Confirm";
  
  mount(<Confirm />);

  Options:

  • wrapper?: ComponentType<{ children: ReactNode }> — wraps the rendered element in providers (theme, i18n, router). The wrapper runs inside the Confirm's own React tree, so context from story decorators does not propagate; for reactive providers tied to host state (e.g. Storybook globals), subscribe inside the wrapper via useGlobals from @storybook/preview-api or an external store.
  • container?: HTMLElement — mount target; defaults to a fresh <div data-react-call-host> appended to document.body.

  Idempotent under HMR: subsequent mount() calls re-render against the cached root (kept on globalThis[Symbol.for('react-call.host')]) rather than creating a second one, so an open Confirm.call() survives edits to preview.tsx.

  Adds react-dom as an optional peer dependency (mirrors the vite optional peer). Consumers who don't import react-call/host see no install change.

  See ADR-0016 for the design discussion.
