Set The Title Of A Page

One of the reserved functions in a Remix route is meta. Defining this function allows you to specify meta tags that appear in the <head> of a page, including the <title> tag.

import type {
  MetaFunction,
  LoaderFunction
} from "@remix-run/node";

export const loader: LoaderFunction = async ({ params }) => {
  // load and return the post
};

export const meta: MetaFunction = ({ data }) => {
  const { title } = data?.posts || {}

  return {
    title: title || "An Article",
  };
};

export default function Post() {
  /* render the post */
}

The meta function returns an object that contains key-value pairs of meta tags. We can include something like title: 'Sign Up' for a static title. Or we can access things like location, params, and even data from the loader to produce a content-specific title.

If open one of these /posts/$slug pages in the browser and crack open the View Source, we'll be able to see the <title>Name Of My Post</title> tag within the <head> tag.
