Params

opts.basename

The basename to use when matching the request.

opts.createTemporaryReferenceSet

A function that returns a temporary reference set for the request, used to track temporary references in the RSC stream.

opts.decodeAction

Your react-server-dom-xyz/server's decodeAction function, responsible for loading a server action.

opts.decodeFormState

A function responsible for decoding form state for progressively enhanceable forms with React's useActionState using your react-server-dom-xyz/server's decodeFormState.

opts.decodeReply

Your react-server-dom-xyz/server's decodeReply function, used to decode the server function's arguments and bind them to the implementation for invocation by the router.

opts.generateResponse

A function responsible for using your renderToReadableStream to generate a Response encoding the unstable_RSCPayload.

opts.loadServerAction

Your react-server-dom-xyz/server's loadServerAction function, used to load a server action by ID.

opts.onError

An optional error handler that will be called with any errors that occur during the request processing.

opts.request

The Request to match against.

opts.requestContext

An instance of unstable_RouterContextProvider that should be created per request, to be passed to actions, loaders and middleware.
