 You can also add the equivalent of a `beforeunload` event for [[SPA Routing]] via the `prenav` event.
 ```ts
 document.addEventListener("prenav", () => {
  // executed after an SPA navigation is triggered but
  // before the page is replaced
  // one usage pattern is to store things in sessionStorage

 It is best practice to track any event handlers via `window.addCleanup` to prevent memory leaks.
 This will get called on page navigation.

 You can customize this by changing the entries of the `omit` set. Simply add all folder or file names you want to remove.

      } else {
        node.displayName = "📁 " + node.displayName
      }
    }
  },
 })
 ```
 ### Putting it all together
 In this example, we're going to customize the explorer by using functions from examples above to [[#Add emoji prefix | add emoji prefixes]], [[#remove-list-of-elements-filter| filter out some folders]] and [[#use-sort-to-put-files-first | sort with files above folders]].
 ```ts title="quartz.layout.ts"
 Component.Explorer({
  filterFn: sampleFilterFn,
  mapFn: sampleMapFn,
  sortFn: sampleSortFn,
  order: ["filter", "sort", "map"],
 })
 ```
 Notice how we customized the `order` array here. This is done because the default order applies the `sort` function last. While this normally works well, it would cause unintended behavior here, since we changed the first characters of all display names. In our example, `sort` would be applied based off the emoji prefix instead of the first _real_ character.
 To fix this, we just changed around the order and apply the `sort` function before changing the display names in the `map` function.
 ### Use `sort` with pre-defined sort order
 Here's another example where a map containing file/folder names (as slugs) is used to define the sort order of the explorer in quartz. All files/folders that aren't listed inside of `nameOrderMap` will appear at the top of that folders hierarchy level.
 It's also worth mentioning, that the smaller the number set in `nameOrderMap`, the higher up the entry will be in the explorer. Incrementing every folder/file by 100, makes ordering files in their folders a lot easier. Lastly, this example still allows you to use a `mapFn` or frontmatter titles to change display names, as it uses slugs for `nameOrderMap` (which is unaffected by display name changes).
 ```ts title="quartz.layout.ts"
 Component.Explorer({
  sortFn: (a, b) => {
    const nameOrderMap: Record<string, number> = {
      "poetry-folder": 100,
      "essay-folder": 200,
      "research-paper-file": 201,
      "dinosaur-fossils-file": 300,
      "other-folder": 400,
    }
    let orderA = 0
    let orderB = 0
    if (a.file && a.file.slug) {
      orderA = nameOrderMap[a.file.slug] || 0
    } else if (a.name) {
      orderA = nameOrderMap[a.name] || 0
    }
    if (b.file && b.file.slug) {
      orderB = nameOrderMap[b.file.slug] || 0
    } else if (b.name) {
      orderB = nameOrderMap[b.name] || 0
    }
    return orderA - orderB
  },
 })
 ```
 For reference, this is how the quartz explorer window would look like with that example:
 ```
 📖 Poetry Folder
 📑 Essay Folder
    ⚗️ Research Paper File
 🦴 Dinosaur Fossils File
 🔮 Other Folder
 ```
 And this is how the file structure would look like:
 ```
 index.md
 poetry-folder
    index.md
 essay-folder
    index.md
    research-paper-file.md
 dinosaur-fossils-file.md

 Quartz can also dynamically generate and use new cover images for every page to be used in link previews on social media for you.
 ## Showcase

+After enabling the [[CustomOgImages]] emitter plugin, the social media link preview for [[authoring content | Authoring Content]] looks like this:
 | Light                               | Dark                               |

+## Configuration
-## Customization
+This functionality is provided by the [[CustomOgImages]] plugin. See the plugin page for customization options.
 You can customize how images will be generated in the quartz config.
 For example, here's what the default configuration looks like if you set `generateSocialImages: true`:
 ```typescript title="quartz.config.ts"
 generateSocialImages: {
  colorScheme: "lightMode", // what colors to use for generating image, same as theme colors from config, valid values are "darkMode" and "lightMode"
  width: 1200, // width to generate with (in pixels)
  height: 630, // height to generate with (in pixels)
  excludeRoot: false, // wether to exclude "/" index path to be excluded from auto generated images (false = use auto, true = use default og image)
 }
 ```
 ---
 ### Frontmatter Properties
 > [!tip] Hint
 >
 > Overriding social media preview properties via frontmatter still works even if `generateSocialImages` is disabled.
 The following properties can be used to customize your link previews:
 | Property            | Alias            | Summary                             |
 | ------------------- | ---------------- | ----------------------------------- |
 | `socialDescription` | `description`    | Description to be used for preview. |
 | `socialImage`       | `image`, `cover` | Link to preview image.              |
 The `socialImage` property should contain a link to an image relative to `quartz/static`. If you have a folder for all your images in `quartz/static/my-images`, an example for `socialImage` could be `"my-images/cover.png"`.
 > [!info] Info
 >
 > The priority for what image will be used for the cover image looks like the following: `frontmatter property > generated image (if enabled) > default image`.
 >
 > The default image (`quartz/static/og-image.png`) will only be used as a fallback if nothing else is set. If `generateSocialImages` is enabled, it will be treated as the new default per page, but can be overwritten by setting the `socialImage` frontmatter property for that page.
 ---
 ### Fully customized image generation
 You can fully customize how the images being generated look by passing your own component to `generateSocialImages.imageStructure`. This component takes html/css + some page metadata/config options and converts it to an image using [satori](https://github.com/vercel/satori). Vercel provides an [online playground](https://og-playground.vercel.app/) that can be used to preview how your html/css looks like as a picture. This is ideal for prototyping your custom design.
 It is recommended to write your own image components in `quartz/util/og.tsx` or any other `.tsx` file, as passing them to the config won't work otherwise. An example of the default image component can be found in `og.tsx` in `defaultImage()`.
 > [!tip] Hint
 >
 > Satori only supports a subset of all valid CSS properties. All supported properties can be found in their [documentation](https://github.com/vercel/satori#css).
 Your custom image component should have the `SocialImageOptions["imageStructure"]` type, to make development easier for you. Using a component of this type, you will be passed the following variables:
 ```ts
 imageStructure: (
  cfg: GlobalConfiguration, // global Quartz config (useful for getting theme colors and other info)
  userOpts: UserOpts, // options passed to `generateSocialImage`
  title: string, // title of current page
  description: string, // description of current page
  fonts: SatoriOptions["fonts"], // header + body font
 ) => JSXInternal.Element
 ```
 Now, you can let your creativity flow and design your own image component! For reference and some cool tips, you can check how the markup for the default image looks.
 > [!example] Examples
 >
 > Here are some examples for markup you may need to get started:
 >
 > - Get a theme color
 >
 >   `cfg.theme.colors[colorScheme].<colorName>`, where `<colorName>` corresponds to a key in `ColorScheme` (defined at the top of `quartz/util/theme.ts`)
 >
 > - Use the page title/description
 >
 >   `<p>{title}</p>`/`<p>{description}</p>`
 >
 > - Use a font family
 >
 >   Detailed in the Fonts chapter below
 ---
 ### Fonts
 You will also be passed an array containing a header and a body font (where the first entry is header and the second is body). The fonts matches the ones selected in `theme.typography.header` and `theme.typography.body` from `quartz.config.ts` and will be passed in the format required by [`satori`](https://github.com/vercel/satori). To use them in CSS, use the `.name` property (e.g. `fontFamily: fonts[1].name` to use the "body" font family).
 An example of a component using the header font could look like this:
 ```tsx title="socialImage.tsx"
 export const myImage: SocialImageOptions["imageStructure"] = (...) => {
  return <p style={{ fontFamily: fonts[0].name }}>Cool Header!</p>
 }
 ```
 > [!example]- Local fonts
 >
 > For cases where you use a local fonts under `static` folder, make sure to set the correct `@font-face` in `custom.scss`
 >
 > ```scss title="custom.scss"
 > @font-face {
 >   font-family: "Newsreader";
 >   font-style: normal;
 >   font-weight: normal;
 >   font-display: swap;
 >   src: url("/static/Newsreader.woff2") format("woff2");
 > }
 > ```
 >
 > Then in `quartz/util/og.tsx`, you can load the satori fonts like so:
 >
 > ```tsx title="quartz/util/og.tsx"
 > const headerFont = joinSegments("static", "Newsreader.woff2")
 > const bodyFont = joinSegments("static", "Newsreader.woff2")
 >
 > export async function getSatoriFont(cfg: GlobalConfiguration): Promise<SatoriOptions["fonts"]> {
 >   const headerWeight: FontWeight = 700
 >   const bodyWeight: FontWeight = 400
 >
 >   const url = new URL(`https://${cfg.baseUrl ?? "example.com"}`)
 >
 >   const [header, body] = await Promise.all(
 >     [headerFont, bodyFont].map((font) =>
 >       fetch(`${url.toString()}/${font}`).then((res) => res.arrayBuffer()),
 >     ),
 >   )
 >
 >   return [
 >     { name: cfg.theme.typography.header, data: header, weight: headerWeight, style: "normal" },
 >     { name: cfg.theme.typography.body, data: body, weight: bodyWeight, style: "normal" },
 >   ]
 > }
 > ```
 >
 > This font then can be used with your custom structure
 ### Local testing
 To test how the full preview of your page is going to look even before deploying, you can forward the port you're serving quartz on. In VSCode, this can easily be achieved following [this guide](https://code.visualstudio.com/docs/editor/port-forwarding) (make sure to set `Visibility` to `public` if testing on external tools like [opengraph.xyz](https://www.opengraph.xyz/)).
 If you have `generateSocialImages` enabled, you can check out all generated images under `public/static/social-images`.
 ## Technical info
 Images will be generated as `.webp` files, which helps to keep images small (the average image takes ~`19kB`). They are also compressed further using [sharp](https://sharp.pixelplumbing.com/).
 When using images, the appropriate [Open Graph](https://ogp.me/) and [Twitter](https://developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started) meta tags will be set to ensure they work and look as expected.
 ## Examples
 Besides the template for the default image generation (found under `quartz/util/og.tsx`), you can also add your own! To do this, you can either edit the source code of that file (not recommended) or create a new one (e.g. `customSocialImage.tsx`, source shown below).
 After adding that file, you can update `quartz.config.ts` to use your image generation template as follows:
 ```ts
 // Import component at start of file
 import { customImage } from "./quartz/util/customSocialImage.tsx"
 // In main config
 const config: QuartzConfig = {
  ...
  generateSocialImages: {
    ...
    imageStructure: customImage, // tells quartz to use your component when generating images
  },
 }
 ```
 The following example will generate images that look as follows:
 | Light                                      | Dark                                      |
 | ------------------------------------------ | ----------------------------------------- |
 | ![[custom-social-image-preview-light.png]] | ![[custom-social-image-preview-dark.png]] |
 This example (and the default template) use colors and fonts from your theme specified in the quartz config. Fonts get passed in as a prop, where `fonts[0]` will contain the header font and `fonts[1]` will contain the body font (more info in the [[#fonts]] section).

 title: Higher-Order Layout Components
 ---
 Quartz provides several higher-order components that help with layout composition and responsive design. These components wrap other components to add additional functionality or modify their behavior.
 ## `Flex` Component
 The `Flex` component creates a [flexible box layout](https://developer.mozilla.org/en-US/docs/Web/CSS/flex) that can arrange child components in various ways. It's particularly useful for creating responsive layouts and organizing components in rows or columns.
 ```typescript
 type FlexConfig = {
  components: {
    Component: QuartzComponent
    grow?: boolean // whether component should grow to fill space
    shrink?: boolean // whether component should shrink if needed
    basis?: string // initial main size of the component
    order?: number // order in flex container
    align?: "start" | "end" | "center" | "stretch" // cross-axis alignment
    justify?: "start" | "end" | "center" | "between" | "around" // main-axis alignment
  }[]
  direction?: "row" | "row-reverse" | "column" | "column-reverse"
  wrap?: "nowrap" | "wrap" | "wrap-reverse"
  gap?: string
 }
 ```
 ### Example Usage
 ```typescript
 Component.Flex({
  components: [
    {
      Component: Component.Search(),
      grow: true, // Search will grow to fill available space
    },
    { Component: Component.Darkmode() }, // Darkmode keeps its natural size
  ],
  direction: "row",
  gap: "1rem",
 })
 ```
 ## `MobileOnly` Component
 The `MobileOnly` component is a wrapper that makes its child component only visible on mobile devices. This is useful for creating responsive layouts where certain components should only appear on smaller screens.
 ### Example Usage
 ```typescript
 Component.MobileOnly(Component.Spacer())
 ```
 ## `DesktopOnly` Component
 The `DesktopOnly` component is the counterpart to `MobileOnly`. It makes its child component only visible on desktop devices. This helps create responsive layouts where certain components should only appear on larger screens.
 ### Example Usage
 ```typescript
 Component.DesktopOnly(Component.TableOfContents())
 ```

 title: Custom OG Images
 tags:
  - feature/emitter
 ---
 The Custom OG Images emitter plugin generates social media preview images for your pages. It uses [satori](https://github.com/vercel/satori) to convert HTML/CSS into images, allowing you to create beautiful and consistent social media preview cards for your content.
 > [!note]
 > For information on how to add, remove or configure plugins, see the [[configuration#Plugins|Configuration]] page.
 ## Features
 - Automatically generates social media preview images for each page
 - Supports both light and dark mode themes
 - Customizable through frontmatter properties
 - Fallback to default image when needed
 - Full control over image design through custom components
 ## Configuration
 > [!info] Info
 >
 > The `baseUrl` property in your [[configuration]] must be set properly for social images to work correctly, as they require absolute paths.
 This plugin accepts the following configuration options:
 ```typescript title="quartz.config.ts"
 import { CustomOgImages } from "./quartz/plugins/emitters/ogImage"
 const config: QuartzConfig = {
  plugins: {
    emitters: [
      CustomOgImages({
        colorScheme: "lightMode", // what colors to use for generating image, same as theme colors from config, valid values are "darkMode" and "lightMode"
        width: 1200, // width to generate with (in pixels)
        height: 630, // height to generate with (in pixels)
        excludeRoot: false, // wether to exclude "/" index path to be excluded from auto generated images (false = use auto, true = use default og image)
        imageStructure: defaultImage, // custom image component to use
      }),
    ],
  },
 }
 ```
 ### Configuration Options
 | Option           | Type      | Default      | Description                                                       |
 | ---------------- | --------- | ------------ | ----------------------------------------------------------------- |
 | `colorScheme`    | string    | "lightMode"  | Theme to use for generating images ("darkMode" or "lightMode")    |
 | `width`          | number    | 1200         | Width of the generated image in pixels                            |
 | `height`         | number    | 630          | Height of the generated image in pixels                           |
 | `excludeRoot`    | boolean   | false        | Whether to exclude the root index page from auto-generated images |
 | `imageStructure` | component | defaultImage | Custom component to use for image generation                      |
 ## Frontmatter Properties
 The following properties can be used to customize your link previews:
 | Property            | Alias            | Summary                             |
 | ------------------- | ---------------- | ----------------------------------- |
 | `socialDescription` | `description`    | Description to be used for preview. |
 | `socialImage`       | `image`, `cover` | Link to preview image.              |
 The `socialImage` property should contain a link to an image relative to `quartz/static`. If you have a folder for all your images in `quartz/static/my-images`, an example for `socialImage` could be `"my-images/cover.png"`.
 > [!info] Info
 >
 > The priority for what image will be used for the cover image looks like the following: `frontmatter property > generated image (if enabled) > default image`.
 >
 > The default image (`quartz/static/og-image.png`) will only be used as a fallback if nothing else is set. If the Custom OG Images emitter plugin is enabled, it will be treated as the new default per page, but can be overwritten by setting the `socialImage` frontmatter property for that page.
 ## Customization
 You can fully customize how the images being generated look by passing your own component to `imageStructure`. This component takes JSX + some page metadata/config options and converts it to an image using [satori](https://github.com/vercel/satori). Vercel provides an [online playground](https://og-playground.vercel.app/) that can be used to preview how your JSX looks like as a picture. This is ideal for prototyping your custom design.
 ### Fonts
 You will also be passed an array containing a header and a body font (where the first entry is header and the second is body). The fonts matches the ones selected in `theme.typography.header` and `theme.typography.body` from `quartz.config.ts` and will be passed in the format required by [`satori`](https://github.com/vercel/satori). To use them in CSS, use the `.name` property (e.g. `fontFamily: fonts[1].name` to use the "body" font family).
 An example of a component using the header font could look like this:
 ```tsx title="socialImage.tsx"
 export const myImage: SocialImageOptions["imageStructure"] = (...) => {
  return <p style={{ fontFamily: fonts[0].name }}>Cool Header!</p>
 }
 ```
 > [!example]- Local fonts
 >
 > For cases where you use a local fonts under `static` folder, make sure to set the correct `@font-face` in `custom.scss`
 >
 > ```scss title="custom.scss"
 > @font-face {
 >   font-family: "Newsreader";
 >   font-style: normal;
 >   font-weight: normal;
 >   font-display: swap;
 >   src: url("/static/Newsreader.woff2") format("woff2");
 > }
 > ```
 >
 > Then in `quartz/util/og.tsx`, you can load the Satori fonts like so:
 >
 > ```tsx title="quartz/util/og.tsx"
 > import { joinSegments, QUARTZ } from "../path"
 > import fs from "fs"
 > import path from "path"
 >
 > const newsreaderFontPath = joinSegments(QUARTZ, "static", "Newsreader.woff2")
 > export async function getSatoriFonts(headerFont: FontSpecification, bodyFont: FontSpecification) {
 >   // ... rest of implementation remains same
 >   const fonts: SatoriOptions["fonts"] = [
 >     ...headerFontData.map((data, idx) => ({
 >       name: headerFontName,
 >       data,
 >       weight: headerWeights[idx],
 >       style: "normal" as const,
 >     })),
 >     ...bodyFontData.map((data, idx) => ({
 >       name: bodyFontName,
 >       data,
 >       weight: bodyWeights[idx],
 >       style: "normal" as const,
 >     })),
 >     {
 >       name: "Newsreader",
 >       data: await fs.promises.readFile(path.resolve(newsreaderFontPath)),
 >       weight: 400,
 >       style: "normal" as const,
 >     },
 >   ]
 >
 >   return fonts
 > }
 > ```
 >
 > This font then can be used with your custom structure.
 ## Examples
 Here are some example image components you can use as a starting point:
