Header and Footer

The built-in themes keep global actions deliberately compact. The header always contains the linked brand mark and can display configured links. The sidebar footer can show website and GitHub links. Grain keeps the color-mode toggle there; Moss and Shade place that toggle in the header.

Add header links

Use navigation for links in the theme's header slot. It is declarative and serializable, so the same configuration works in React Router, Next.js, and Astro without passing JSX through a browser-data module.

import { heyoDocs } from "@heyo-sh/heyo-docs/config";export default heyoDocs({  navigation: [    { label: "Sign in", href: "https://app.acme.com/sign-in" },    { label: "Status", href: "https://status.acme.com" },  ],});

Each item requires a non-empty label and href. Relative links use the framework's configured documentation link component. HTTP(S) links open as ordinary external links in a new tab with rel="noreferrer".

Keep the list short: one or two high-value destinations are usually enough. Documentation pages belong in the sidebar; header links are best for an app, a status page, or a GitHub repository.

Customize beyond links

navigation deliberately does not accept React elements, menus, user state, or arbitrary scripts. That keeps heyo-docs.config.ts portable across build and browser environments. For a signed-in menu, a custom CTA, or a different header structure, compose it in the application shell or supply theme components to DocsApp. Do not create a second Heyo Docs configuration merely to add header UI.

Configure footer links

The sidebar footer supports one website link and one GitHub link:

export default heyoDocs({  footer: {    website: "https://acme.com",    github: "https://github.com/acme/docs",  },});

Both values must be absolute URLs. When set, every built-in theme renders recognizable globe and GitHub icon buttons that open in a new tab with rel="noreferrer". Grain keeps its color-mode button at the other edge of the footer; Moss and Shade render it in the header.

Omit either property to remove just that link. With an empty footer object, Grain retains only its color-mode control in the footer; Moss and Shade leave the footer empty.

Verify links and keyboard access

After a change, test every action with a keyboard as well as a pointer. Check that labels make sense without icons, external URLs are correct, focus is visible in both color modes, and the header remains usable at mobile width. Header and footer URLs are public build configuration, so never put secrets or single-use tokens in them.
