## 2.1.0

### Minor Changes

- 47c25e3: Add prerender data hydration for Code Components.

  - **`useSuspenseData(key, loader)`** — Suspense-friendly hook that owns the fetch: runs the loader during prerender, records the result, and replays it synchronously on hydrate (no refetch, no first-paint loading flash). Returns `{ data }`. For components that fetch their own data.
  - **`usePrerenderData<T>(key)`** — read-only seed for components whose fetching is owned by a Suspense-capable library (React Query `useSuspenseQuery`, SWR `{ suspense: true }`). Returns `{ data }` — the prerendered data (or `undefined`). Seed the library via `initialData` / `fallbackData`.
  - **`useHydrateData(key, value)`** — companion hook that records a library-fetched value into the prerender snapshot during render. Takes the **same `key`** you passed to `usePrerenderData` and your data library and accepts `T | undefined` (a no-op), so libraries whose `data` stays `T | undefined` (e.g. SWR) need no cast. Being a hook, the rules of hooks keep it out of effects/conditionals.
  - **Keys** are a stable identity: either a plain string (used as-is — handy for a URL + query string) or an array of `string` / `number` / `boolean` segments joined with `:` (e.g. `["todo", id]` → `"todo:id"` in collected data). **First-write-wins** on collision (for both `useSuspenseData` auto-record and `useHydrateData`). Values must be JSON-serializable; not a general client cache (no invalidation/refetch).
  - **`PrerenderDataProvider`** — context for collect (server) vs seeded (client) modes. Exported from `@webflow/react`, `@webflow/react/server`, and the new **`@webflow/react/shared`** subpath (for library bundles that need a single context instance).
  - **`ComponentRuntimeOptions.data`** — optional prerender data map passed to **`ClientRenderer.hydrate`** / **`render`**.
  - **`ServerPrerenderResult.data`** — optional JSON map returned from **`ServerRenderer.prerenderToString`** (and Emotion/styled-components server renderers) when `useSuspenseData` / `useHydrateData` collect entries.
  - Host **`SuspenseBoundary`** wraps code components so the hooks work without a customer `<Suspense>`; use **`ssr: 'prerender'`** so data resolves before first paint.

### Patch Changes

- @webflow/data-types@2.1.0

## 2.0.0

### Major Changes

- 48a5900: - Added `@webflow/react/server` subpath export (use `import … from "@webflow/react/server"`) and moved server-only API `ServerRenderer` into it.
  - `ServerRenderer` now includes `prerenderToString`: render HTML async after Suspense boundaries resolve.
  - `ServerRenderer.renderToString` return type changed to `string | {html: string; styles?: string}` to align with `ComponentServerRendererFactory`

### Minor Changes

- 10896e6: Raise `react`/`react-dom` peer dependency support to all `19.x` minor versions (previous support was until version `19.0.0`)
