Building your application

Head and metadata

SolidStart does not come with a metadata library. In cases where you want to customize the content in the head of your document, you can use the solid-meta library.

The common elements used in the head are:

title: Specifies the title of the page, used by the browser tab and headings of search results.
meta: Specifies a variety of metadata about the page specified by name, ranging from favicon, character set to OG tags for SEO.
link: Adds assets like stylesheets or scripts for the browser to load for the page.
style: Adds inline styles to the page.

Inside a Route component

When applying metadata to a specific route, you can use the Title:

import { Title } from "@solidjs/meta";

export default function About() {
  return (
    <>
      <Title>About</Title>
      <h1>About</h1>
    </>
  );
}

These tags will be applied for that specific route only and will be removed from document.head once a user navigates away from the page. routeData can also be used here to create titles and SEO metadata that is specific to the dynamic parts of the route.

Adding a site-suffix in Title

Custom components can be created to wrap the Title component to add a site-specific prefix to all the titles:

export default function MySiteTitle(props) {
  return <Title>{props.children} | My Site</Title>;
}

import MySiteTitle from "~/components/MySiteTitle";

export default function About() {
  return (
    <>
      <MySiteTitle>About</MySiteTitle>
      <h1>About</h1>
    </>
  );
}

Using async data in `Title`

Resources can be used to create titles specific to the dynamic parts of the route:

import { Title } from "@solidjs/meta";
import { RouteSectionProps } from "@solidjs/router";
import { createResource, Show } from "solid-js";

export default function User(props: RouteSectionProps) {
  const [user] = createResource(() => fetchUser(props.params.id));

  return (
    <Show when={user()}>
      <Title>{user()?.name}</Title>
      <h1>{user()?.name}</h1>
    </Show>
  );
}

For this example, routeData can be used to retrieve the user's name from the id in /users/:id and use it in the Title component. Similarly, other information can be used to build up other tags for SEO.

Adding SEO tags

SEO tags like og:title, og:description, og:image, use the Meta component. Since these tags may want to be used across multiple routes, they can be added inside the Head of the root.tsx file.

export default function Root() {
  return (
    <Html lang="en">
      <Head>
        <Meta
          property="og:image"
          content="https://example.com/image.jpg"
        />
        <Meta
          property="og:image:alt"
          content="Welcome to my site"
        />
        <Meta property="og:image:width" content="1200" />
        <Meta property="og:image:height" content="600" />
        <Meta property="og:site_name" content="GitHub" />
      </Head>
    </Html>
  );
}

If you need to add route specific information inside your route, much like the Title component, you can use the Meta component within the desired route. This overrides the Meta tags used within the Head component.

import MySiteTitle from "~/components/MySiteTitle";

export default function About() {
  return (
    <>
      <MySiteTitle>About</MySiteTitle>
      <Meta name="description" content="This is my content tag." />
      <Meta
        property="og:title"
        content="Welcome to my site!"
      />
      <Meta
        property="og:description"
        content="A website"
      />
      <h1>About</h1>
    </>
  );
}
