Nordstar

Header

A site or section header with a logo slot and an optional menu. Sticks to the top of the viewport by default.

When to use

  • As the first child of a top-level View on a page route.
  • For section dividers inside long pages where each section has its own primary navigation.

When not to use

  • For inline content cards — use Card.Header (a sub-component of Card) instead.
  • For the title row of a settings panel — that's Heading + Card.

Installation

pnpm add @nordcom/nordstar-header
import { Header } from '@nordcom/nordstar';

Anatomy

Header exposes three sub-components, composed inside the wrapper:

  • Header.Logo — the leftmost identity slot. Often wraps a brand mark or a <Link> back to the home page.
  • Header.Menu — the navigation list, typically rightmost on desktop.
  • Header.Menu.Link — one nav entry. Renders as a styled link.

Basic usage

Nordstar
import { Header } from '@nordcom/nordstar';

export default function Example() {
    return (
        <Header sticky={false}>
            <Header.Logo>Nordstar</Header.Logo>
        </Header>
    );
}

With navigation menu

Nordstar
import { Header } from '@nordcom/nordstar';

export default function Example() {
    return (
        <Header sticky={false}>
            <Header.Logo>Nordstar</Header.Logo>
            <Header.Menu>
                <Header.Menu.Link>Docs</Header.Menu.Link>
                <Header.Menu.Link>Components</Header.Menu.Link>
                <Header.Menu.Link>GitHub</Header.Menu.Link>
            </Header.Menu>
        </Header>
    );
}

(The examples above pass sticky={false} so the header doesn't stick to the preview frame's top — in production, leave it sticky.)

Composition

Pair Header with View for full-page layouts:

<View>
    <Header>
        <Header.Logo>
            <Link href="/">Acme</Link>
        </Header.Logo>
        <Header.Menu>
            <Header.Menu.Link>
                <Link href="/docs">Docs</Link>
            </Header.Menu.Link>
            <Header.Menu.Link>
                <Link href="/blog">Blog</Link>
            </Header.Menu.Link>
        </Header.Menu>
    </Header>
    <main>…</main>
</View>

Wrap the children of Header.Logo and each Header.Menu.Link in real <Link> elements when they navigate — Nordstar leaves routing to the host app.

Accessibility

  • Make sure Header.Logo's child has accessible text. An icon-only logo needs an aria-label or visually-hidden text.
  • Inside Header.Menu, prefer real anchor elements (<a>, <Link>) over click-only buttons so the URL is real and the page is bookmarkable.
