App router page type

[crude shard]

I know this may have been asked a million times but couldn't find the reference: how can we type pages for the App Router? For instance "const MyPage = ({params: {responseId }}: IsThereAnOfficalTypeForThis?<{responseId: string}>) => {... }"

[little pagoda]

there is no official type yet

all the snippets in the docs are manually typed
