Relative And Absolute Paths In Links

Remix has its own routing system built in. The directories and files that you place under app/routes will all make up the routes of the app. Routes are pages in the app. And pages are meant to be linked to.

Remix's Link component can handle both relative and absolute paths with the to prop.

Here is a link with relative path.

// app/routes/posts/index.tsx
import { Link } from "@remix-run/react";

export default function Posts() {
  return (
    <Link to="admin">
      Admin
    </Link>
  )
}

Because the Link is rendered within the posts/ directory, the link will point to localhost:3000/posts/admin.

And here is an absolute path.

// app/routes/posts/index.tsx
import { Link } from "@remix-run/react";

export default function Posts() {
  return (
    <Link to="/admin">
      Admin
    </Link>
  )
}

Notice that the only change was putting a leading slash in front of admin in the to prop. Just like Unix path names, that indicates that the path is an absolute one, anchored to the root. It doesn't matter that it is in the /posts directory. It will point to localhost:3000/admin.
