Frontmatter Reference

यह कंटेंट अभी तक आपकी भाषा में उपलब्ध नहीं है।

You can customize individual Markdown and MDX pages in Starlight by setting values in their frontmatter. For example, a regular page might set title and description fields:

---
title: About this project
description: Learn more about the project I’m working on.
---

Welcome to the about page!

Frontmatter fields

`title` (required)

type: string

You must provide a title for every page. This will be displayed at the top of the page, in browser tabs, and in page metadata.

`description`

type: string

The page description is used for page metadata and will be picked up by search engines and in social media previews.

`slug`

type: string

Override the slug of the page. See “Defining custom IDs” in the Astro docs for more details.

`editUrl`

type: string | boolean

Overrides the global editLink config. Set to false to disable the “Edit page” link for a specific page or provide an alternative URL where the content of this page is editable.

`head`

type: HeadConfig[]

You can add additional tags to your page’s <head> using the head frontmatter field. This means you can add custom styles, metadata or other tags to a single page. Similar to the global head option.

---
title: About us
head:
  # Use a custom <title> tag
  - tag: title
    content: Custom about title
---

`tableOfContents`

type: false | { minHeadingLevel?: number; maxHeadingLevel?: number; }

Overrides the global tableOfContents config. Customize the heading levels to be included or set to false to hide the table of contents on this page.

---
title: Page with only H2s in the table of contents
tableOfContents:
  minHeadingLevel: 2
  maxHeadingLevel: 2
---

---
title: Page with no table of contents
tableOfContents: false
---

`template`

type: 'doc' | 'splash'
default: 'doc'

Set the layout template for this page. Pages use the 'doc' layout by default. Set to 'splash' to use a wider layout without any sidebars designed for landing pages.

`hero`

type: HeroConfig

Add a hero component to the top of this page. Works well with template: splash.

For example, this config shows some common options, including loading an image from your repository.

---
title: My Home Page
template: splash
hero:
  title: 'My Project: Stellar Stuff Sooner'
  tagline: Take your stuff to the moon and back in the blink of an eye.
  image:
    alt: A glittering, brightly colored logo
    file: ~/assets/logo.png
  actions:
    - text: Tell me more
      link: /getting-started/
      icon: right-arrow
    - text: View on GitHub
      link: https://github.com/astronaut/my-project
      icon: external
      variant: minimal
      attrs:
        rel: me
---

You can display different versions of the hero image in light and dark modes.

---
hero:
  image:
    alt: A glittering, brightly colored logo
    dark: ~/assets/logo-dark.png
    light: ~/assets/logo-light.png
---

`HeroConfig`

interface HeroConfig {
  title?: string;
  tagline?: string;
  image?:
    | {
        // Relative path to an image in your repository.
        file: string;
        // Alt text to make the image accessible to assistive technology
        alt?: string;
      }
    | {
        // Relative path to an image in your repository to be used for dark mode.
        dark: string;
        // Relative path to an image in your repository to be used for light mode.
        light: string;
        // Alt text to make the image accessible to assistive technology
        alt?: string;
      }
    | {
        // Raw HTML to use in the image slot.
        // Could be a custom `<img>` tag or inline `<svg>`.
        html: string;
      };
  actions?: Array<{
    text: string;
    link: string;
    variant?: 'primary' | 'secondary' | 'minimal';
    icon?: string;
    attrs?: Record<string, string | number | boolean>;
  }>;
}

`banner`

type: { content: string }

Displays an announcement banner at the top of this page.

The content value can include HTML for links or other content. For example, this page displays a banner including a link to example.com.

---
title: Page with a banner
banner:
  content: |
    We just launched something cool!
    <a href="https://example.com">Check it out</a>
---

`lastUpdated`

type: Date | boolean

Overrides the global lastUpdated option. If a date is specified, it must be a valid YAML timestamp and will override the date stored in Git history for this page.

---
title: Page with a custom last update date
lastUpdated: 2022-08-09
---

`prev`

type: boolean | string | { link?: string; label?: string }

Overrides the global pagination option. If a string is specified, the generated link text will be replaced and if an object is specified, both the link and the text will be overridden.

---
# Hide the previous page link
prev: false
---

---
# Override the previous page link text
prev: Continue the tutorial
---

---
# Override both the previous page link and text
prev:
  link: /unrelated-page/
  label: Check out this other page
---

`next`

type: boolean | string | { link?: string; label?: string }

Same as prev but for the next page link.

---
# Hide the next page link
next: false
---

`pagefind`

type: boolean
default: true

Set whether this page should be included in the Pagefind search index. Set to false to exclude a page from search results:

---
# Hide this page from the search index
pagefind: false
---

`draft`

type: boolean
default: false

Set whether this page should be considered a draft and not be included in production builds. Set to true to mark a page as a draft and make it only visible during development.

---
# Exclude this page from production builds
draft: true
---

Because draft pages are not included in build output, you cannot add draft pages directly to your site sidebar config using slugs. Draft pages in directories used for autogenerated sidebar groups are automatically excluded in production builds.

`sidebar`

type: SidebarConfig

Control how this page is displayed in the sidebar, when using an autogenerated link group.

`SidebarConfig`

interface SidebarConfig {
  label?: string;
  order?: number;
  hidden?: boolean;
  badge?: string | BadgeConfig;
  attrs?: Record<string, string | number | boolean | undefined>;
}

`label`

type: string
default: the page title

Set the label for this page in the sidebar when displayed in an autogenerated group of links.

---
title: About this project
sidebar:
  label: About
---

`order`

type: number

Control the order of this page when sorting an autogenerated group of links. Lower numbers are displayed higher up in the link group.

---
title: Page to display first
sidebar:
  order: 1
---

`hidden`

type: boolean
default: false

Prevents this page from being included in an autogenerated sidebar group.

---
title: Page to hide from autogenerated sidebar
sidebar:
  hidden: true
---

`badge`

type: string | BadgeConfig

Add a badge to the page in the sidebar when displayed in an autogenerated group of links. When using a string, the badge will be displayed with a default accent color. Optionally, pass a BadgeConfig object with text, variant, and class fields to customize the badge.

---
title: Page with a badge
sidebar:
  # Uses the default variant matching your site’s accent color
  badge: New
---

---
title: Page with a badge
sidebar:
  badge:
    text: Experimental
    variant: caution
---

`attrs`

type: Record<string, string | number | boolean | undefined>

HTML attributes to add to the page link in the sidebar when displayed in an autogenerated group of links. If autogenerate.attrs is set on the autogenerated group this page belongs to, frontmatter attributes will be merged with the group attributes.

---
title: Page opening in a new tab
sidebar:
  # Opens the page in a new tab
  attrs:
    target: _blank
---

Customize frontmatter schema

The frontmatter schema for Starlight’s docs content collection is configured in src/content.config.ts using the docsSchema() helper:

import { defineCollection } from 'astro:content';
import { docsLoader, i18nLoader } from '@astrojs/starlight/loaders';
import { docsSchema } from '@astrojs/starlight/schema';

export const collections = {
  docs: defineCollection({ loader: docsLoader(), schema: docsSchema() }),
};

Learn more about content collection schemas in “Defining a collection schema” in the Astro docs.

docsSchema() takes the following options:

`extend`

type: Zod schema or function that returns a Zod schema
default: z.object({})

Extend Starlight’s schema with additional fields by setting extend in the docsSchema() options. The value should be a Zod schema.

In the following example, we provide a stricter type for description to make it required and add a new optional category field:

import { defineCollection, z } from 'astro:content';
import { docsLoader } from '@astrojs/starlight/loaders';
import { docsSchema } from '@astrojs/starlight/schema';

export const collections = {
  docs: defineCollection({
    loader: docsLoader(),
    schema: docsSchema({
      extend: z.object({
        // Make a built-in field required instead of optional.
        description: z.string(),
        // Add a new field to the schema.
        category: z.enum(['tutorial', 'guide', 'reference']).optional(),
      }),
    }),
  }),
};

To take advantage of the Astro image() helper, use a function that returns your schema extension:

import { defineCollection, z } from 'astro:content';
import { docsLoader } from '@astrojs/starlight/loaders';
import { docsSchema } from '@astrojs/starlight/schema';

export const collections = {
  docs: defineCollection({
    loader: docsLoader(),
    schema: docsSchema({
      extend: ({ image }) => {
        return z.object({
          // Add a field that must resolve to a local image.
          cover: image(),
        });
      },
    }),
  }),
};
