Releases

@lit-labs/nextjs@0.2.0

Minor Changes

• #4575 aa4fc3ef - Add support for Next.js 14 and App Router. No longer support Next.js 12.

  Note: By default, components in the App Router are React Server Components (RSCs). Deep SSR of Lit components does not work within server components as they result in React hydration mismatch due to the presence of the <template> element in the RSC payload containing the serialized server component tree, and the custom element definitions will not be included with the client bundle either when imported in server component files.

  Make sure any Lit components you wish to use are beyond the 'use client'; boundary. These will still be server rendered for the initial page load just like they did for the Pages Router.

Patch Changes

• Updated dependencies [aa4fc3ef, aa4fc3ef]:
  • @lit-labs/ssr-react@0.3.0

@lit-labs/ssr-react@0.3.0

Minor Changes

• #4575 aa4fc3ef - The Node build of @lit-labs/ssr-react/enable-lit-ssr.js now also monkey-patches react/jsx-runtime to include logic for deeply server-rendering Lit components without modifying jsxImportSource in tsconfig.

  The monkey-patching logic also adds a workaround for inconsistent es module interop behavior in tools like webpack which could lead to errors like TypeError: Cannot set property createElement of [object Module] which has only a getter.

Patch Changes

• #4575 aa4fc3ef - Use a global flag to detect whether @lit-labs/ssr-react/enable-lit-ssr.js was used for coordinating props when server rendering components made with @lit/react.

@lit/react@1.0.5
