thanks.
btw, I am facing a new problem that how to use Dynamic Routes.
I don't know how to read the parameters from the URL that the user inputs.
for example the server hosts:
pages/blog/[slug].tsx
and user access the server by pages/blog/:something

How to let the component exported by [slug].tsx knows the parameter "something". I have tried the parameters

{ Page, pageProps }: { Page: ComponentType<any>, pageProps: any }

but not work

[ije]

you may need the useRouter hook:

import { useRouter } from "https://deno.land/x/[email protected]/mod.ts"

// hypothetically current location patname is '/post/hello-world?theme=dark'
export default function Page() {
  const {
    pathname, // string, sholud be '/post/hello-world'
    pagePath, // string, sholud be '/post/[slug]'
    params,   // object, sholud be {slug: 'hello-world'}
    query     // URLSearchParams, `query.get('theme')` sholud be 'dark'
  } = useRouter()
  ...
}
