High-Level Architecture

Quartz v5 is a fully plugin-based static site generator for digital gardens. Every functional unit — content transformation, filtering, page generation, and UI rendering — is implemented as an external community plugin loaded from Git repositories.

Key architectural decisions:

1. Everything is a plugin. There is no monolithic core. The framework provides the pipeline, loader, and component infrastructure; all domain logic lives in plugins.
2. Git-native plugin distribution. Plugins are cloned from GitHub repositories into .quartz/plugins/ via isomorphic-git. No npm registry required.
3. Declarative configuration. A single quartz.config.yaml declares all plugins, their options, ordering, and layout positions. TypeScript overrides are optional.
4. PageType system. A new abstraction that unifies content rendering, virtual page generation, and layout binding into a single plugin type.
5. Two-phase emit. The PageTypeDispatcher runs first (generating virtual pages), then all other emitters receive content + virtual pages together.

---

Build Pipeline

The build pipeline lives in quartz/build.ts and the quartz/processors/ directory. It follows a linear flow:

1. File Discovery

glob("**/*.*", directory, ignorePatterns)
  → allFiles (all file paths)
  → allSlugs (slugified paths)
  → Extension-stripped slug aliases for PageType extensions (.canvas, .base)

PageType plugins register file extensions (e.g., .canvas, .base). The build adds extension-stripped slug aliases so wikilinks like ![[file.canvas]] resolve to the virtual page slug file.

2. Parse (quartz/processors/parse.ts)

Only .md files are parsed. The parsing pipeline:

Markdown source
  → textTransform()     Transformer plugins modify raw text
  → remark-parse        Markdown → mdast (Markdown AST)
  → markdownPlugins()   Transformer plugins add remark plugins
  → remark-rehype       mdast → hast (HTML AST)
  → htmlPlugins()       Transformer plugins add rehype plugins
  → ProcessedContent    [hast tree, VFile with data]

Each step runs every enabled transformer plugin's corresponding hook in order.

3. Filter (quartz/processors/filter.ts)

ProcessedContent[]
  → filter.shouldPublish(ctx, content)   For each filter plugin
  → FilteredContent[]

Filter plugins decide which files to publish. Examples: remove-draft (excludes draft: true frontmatter), explicit-publish (requires publish: true).

4. Emit (quartz/processors/emit.ts)

Emission is split into two phases to support virtual pages:

Phase 1: PageTypeDispatcher
  ├── Generate virtual pages (tag pages, folder pages, bases pages, etc.)
  ├── Populate ctx.virtualPages
  ├── Render Body components → populate htmlAst (for transclusion)
  └── Emit all pages as HTML

Phase 2: All other emitters
  ├── Receive content + virtualPages merged
  ├── ContentIndex (sitemap, RSS, search index)
  ├── AliasRedirects, CNAME, Favicon, OGImage
  └── ComponentResources (CSS, JS bundles), Assets, Static files

This two-phase approach ensures that emitters like ContentIndex include virtual pages in their output (sitemap, RSS, explorer data).

Incremental Rebuild

During --watch mode, the same two-phase approach applies. partialEmit is used when available to only re-emit changed files. The content map tracks add/change/delete events, and the trie is rebuilt on each partial emit.

---

Plugin System

Plugin Categories

There are 4 processing categories and 1 UI category:

Category	Interface	Key Methods	Purpose
Transformer	QuartzTransformerPluginInstance	textTransform, markdownPlugins, htmlPlugins, externalResources	Transform content during parsing
Filter	QuartzFilterPluginInstance	shouldPublish	Decide which files to include
Emitter	QuartzEmitterPluginInstance	emit, partialEmit, getQuartzComponents, externalResources	Produce output files
PageType	QuartzPageTypePluginInstance	match, generate, body, layout, fileExtensions, priority	Define page rendering and virtual pages
Component	(registered in ComponentRegistry)	QuartzComponent function + static CSS/JS	UI components placed via layout config

A plugin can belong to multiple categories. For example, content-page is both pageType and component — it defines how content pages are matched/rendered AND provides the Body component.

Plugin Lifecycle

quartz.config.yaml
  │
  ▼
1. Read YAML config (config-loader.ts)
  │
  ▼
2. For each enabled plugin entry:
  │  a. Parse source string (e.g., "github:quartz-community/explorer")
  │  b. Clone/update from GitHub via isomorphic-git (gitLoader.ts)
  │  c. Read manifest from package.json "quartz" field
  │  d. Load components into ComponentRegistry (componentLoader.ts)
  │
  ▼
3. Validate dependencies
  │  a. Check all dependencies are present and enabled
  │  b. Verify execution order (dependency must run before dependent)
  │  c. Detect circular dependencies
  │
  ▼
4. Categorize plugins
  │  a. Read category from manifest
  │  b. For dual-category (e.g., ["pageType", "component"]), resolve processing category
  │  c. Component-only plugins are loaded into registry but not into processing pipeline
  │  d. If category unknown, detect by instantiating and inspecting exported methods
  │
  ▼
5. Sort by order within each category (entry.order ?? manifest.defaultOrder ?? 50)
  │
  ▼
6. Instantiate plugins
  │  a. Import module from dist/index.js
  │  b. Find factory function (default export, or "plugin" export, or first matching export)
  │  c. Merge options: { ...manifest.defaultOptions, ...entry.options }
  │  d. Call factory(mergedOptions) → plugin instance
  │
  ▼
7. Build layout (loadQuartzLayout)
  │  a. Resolve component references from ComponentRegistry
  │  b. Apply display wrappers (MobileOnly/DesktopOnly)
  │  c. Apply condition wrappers (ConditionalRender)
  │  d. Resolve flex groups
  │  e. Build per-page-type layout overrides
  │
  ▼
8. Add built-in plugins
  │  a. ComponentResources, Assets, Static (emitters)
  │  b. NotFoundPageType (built-in 404 page)
  │  c. PageTypeDispatcher (wired with resolved layout)
  │
  ▼
9. Return QuartzConfig { configuration, plugins }

Plugin Manifest

Each plugin declares metadata in its package.json under the "quartz" field:

{
  "quartz": {
    "name": "explorer",
    "displayName": "Explorer",
    "category": "component",
    "version": "1.0.0",
    "quartzVersion": ">=5.0.0",
    "dependencies": [],
    "defaultOrder": 50,
    "defaultEnabled": true,
    "defaultOptions": {},
    "components": {
      "Explorer": {
        "displayName": "Explorer",
        "defaultPosition": "left",
        "defaultPriority": 50
      }
    }
  }
}

Field	Type	Description
name	string	Plugin identifier (kebab-case)
displayName	string	Human-readable name
category	string | string[]	One or more of: transformer, filter, emitter, pageType, component
version	string	Plugin version
quartzVersion	string	Compatible Quartz version range
dependencies	string[]	Required plugin sources (e.g., "github:quartz-community/crawl-links")
defaultOrder	number	Default execution order (0-100, lower = runs first)
defaultEnabled	boolean	Whether enabled by default on install
defaultOptions	object	Default options merged with user config
configSchema	object	JSON Schema for options validation
components	Record<string, ComponentManifest>	UI components provided by this plugin

Plugin Template Structure

Every community plugin follows this structure:

plugin-name/
├── src/
│   ├── index.ts              # Main exports (plugin factory + manifest)
│   ├── [plugin-type].ts      # Plugin implementation
│   ├── types.ts              # Type definitions
│   └── components/           # UI components (if any)
│       ├── index.ts          # Component exports
│       ├── Component.tsx     # Preact component
│       └── Component.scss    # Styles
├── dist/                     # Compiled output (tsup)
│   ├── index.js / index.d.ts
│   └── components/
├── package.json              # With "quartz" metadata field
├── tsconfig.json             # TypeScript config
├── tsup.config.ts            # Build config (sass.compile for SCSS)
├── vitest.config.ts          # Test config

├── .prettierrc
├── README.md
├── LICENSE
├── CHANGELOG.md
└── .github/                  # CI workflows

Build configuration (tsup.config.ts):

All plugins use tsup for building. Plugins with SCSS styles use a custom esbuildPlugins entry that compiles SCSS via sass.compile() and injects the CSS as a string export.

---

PageType System

The PageType system is the central innovation of v5. It replaces the previous monolithic page rendering approach with a pluggable, extensible system where each page "type" (content, folder, tag, canvas, bases) is a separate plugin.

Core Interface

interface QuartzPageTypePluginInstance {
  name: string
  priority?: number // Higher = matched first (descending sort)
  fileExtensions?: string[] // e.g., [".canvas"] — registers for slug aliasing
  match: PageMatcher // Determines if this page type handles a given page
  generate?: PageGenerator // Produces virtual pages (tag listings, folder pages, etc.)
  layout: string // Layout key (used for per-page-type overrides)
  frame?: string // PageFrame name (e.g. "full-width", "minimal") — defaults to "default"
  body: QuartzComponentConstructor // The Body component for rendering page content
}

Matchers

The matchers.ts module provides composable matcher factories:

import { match } from "quartz/plugins/pageTypes/matchers"

match.ext(".canvas") // Matches files with .canvas extension
match.slugPrefix("tags/") // Matches slugs starting with "tags/"
match.frontmatter(
  "layout", // Matches based on frontmatter values
  (v) => v === "custom",
)
match.and(m1, m2) // Logical AND
match.or(m1, m2) // Logical OR
match.not(m1) // Logical NOT
match.all() // Always matches
match.none() // Never matches

Virtual Pages

PageType plugins with a generate method produce virtual pages — pages that don't exist as files on disk but are rendered as if they do. Examples:

• Tag pages: One virtual page per tag (e.g., /tags/javascript)
• Folder pages: One virtual page per folder (e.g., /posts/)
• Bases pages: View-based aggregate pages from .base files

Virtual pages are represented as:

interface VirtualPage {
  slug: string
  title: string
  data: Partial<QuartzPluginData> & Record<string, unknown>
}

They are converted to ProcessedContent (with a synthetic hast tree and VFile) by the PageTypeDispatcher.

PageTypeDispatcher

The PageTypeDispatcher (quartz/plugins/pageTypes/dispatcher.ts) is a special emitter plugin that orchestrates all PageType plugins. It runs as Phase 1 of emission and has a 3-phase internal flow:

Phase 1: Generate Virtual Pages
  For each PageType plugin with a generate() method:
    → Call generate({ content, cfg, ctx })
    → Create ProcessedContent entries (defaultProcessedContent)
    → Push to ctx.virtualPages (except 404)
    → Collect in virtualEntries[]

Phase 2: Populate htmlAst
  For each virtual entry:
    → Render BodyComponent via preact-render-to-string
    → Parse HTML string to hast via hast-util-from-html
    → Set tree.children and vfile.data.htmlAst
  (This enables transclusion of virtual pages, e.g., ![[file.canvas]])

Phase 3: Emit Pages
  a. Emit regular pages:
     For each file in content:
       → Find first matching PageType (sorted by priority, descending)
       → Resolve layout (defaults + per-page-type overrides)
       → renderPage() → write HTML
  b. Emit virtual pages:
     For each virtual entry:
       → renderPage() → write HTML

Priority: PageType plugins are sorted by priority (descending, higher = matched first). The first match wins. This allows specialized types (canvas, bases) to take precedence over the generic content type.

---

Layout System

The layout system determines which UI components appear on each page and where they are positioned. It is fully declarative via quartz.config.yaml.

Layout Positions

Each component is placed in one of four positions:

Position	Location	Rendered As
left	Left sidebar	<div class="left sidebar">
right	Right sidebar	<div class="right sidebar">
beforeBody	Above page content	Inside <div class="popover-hint">
afterBody	Below page content	Inside <div class="page-footer">

Additionally, there are structural slots not user-configurable per-component:

• head — Built-in <Head> component (meta tags, CSS links)
• header — Page header area
• footer — Footer component (from footer plugin)

Full Page Layout Structure

<html>
  <head />
  <!-- head -->
  <body>
    <div class="page">
      <body>
        <div class="left sidebar">
          <!-- left[] components by priority -->
        </div>
        <div class="center">
          <div class="page-header">
            <header>
              <!-- header[] components -->
            </header>
            <div class="popover-hint">
              <!-- beforeBody[] components by priority -->
            </div>
          </div>
          <content />
          <!-- pageBody (from PageType) -->
          <hr />
          <div class="page-footer">
            <!-- afterBody[] components by priority -->
          </div>
        </div>
        <div class="right sidebar">
          <!-- right[] components by priority -->
        </div>
        <footer />
        <!-- footer -->
      </body>
    </div>
  </body>
</html>

Priority and Ordering

Each component has a numeric priority. Lower values render first (closer to the top/start of the position).

plugins:
  - source: github:quartz-community/page-title
    layout:
      position: left
      priority: 10 # Renders first in left sidebar

  - source: github:quartz-community/search
    layout:
      position: left
      priority: 20 # Renders second

Groups (Flex Containers)

Components sharing the same group name are collected into a Flex container. The group itself is treated as a single unit with its own priority.

plugins:
  - source: github:quartz-community/search
    layout:
      position: left
      priority: 20
      group: toolbar
      groupOptions:
        grow: true

  - source: github:quartz-community/darkmode
    layout:
      position: left
      priority: 30
      group: toolbar

  - source: github:quartz-community/reader-mode
    layout:
      position: left
      priority: 35
      group: toolbar

layout:
  groups:
    toolbar:
      priority: 15 # Group renders at priority 15 (before search's 20)
      direction: row
      gap: 0.5rem

Group resolution: The resolveGroups() function builds a unified list of ungrouped components and Flex groups, each with a priority. Groups use their explicit priority from layout.groups config, falling back to the first member's priority. The final list is sorted by priority.

FlexGroupConfig options:

Option	Type	Default	Description
priority	number	First member's priority	Sort priority for the group
direction	"row" | "column" | "row-reverse" | "column-reverse"	"row"	Flex direction
wrap	"nowrap" | "wrap" | "wrap-reverse"	—	Flex wrap
gap	string	"1rem"	Gap between items

Per-component groupOptions:

Option	Type	Description
grow	boolean	flex-grow: 1
shrink	boolean	flex-shrink: 1
basis	string	flex-basis value
order	number	CSS order
align	"start" | "end" | "center" | "stretch"	align-self
justify	"start" | "end" | "center" | "between" | "around"	justify-self

Display Modifiers

Components can be conditionally shown based on viewport:

layout:
  display: mobile-only     # Only visible on mobile
  display: desktop-only    # Only visible on desktop
  display: all             # Always visible (default)

Under the hood, mobile-only wraps the component in MobileOnly() (renders a <div> with display: contents that hides on desktop via CSS media query), and desktop-only wraps in DesktopOnly().

Conditions

Components can be conditionally rendered based on page data:

layout:
  condition: not-index # Don't render on the index page

Built-in conditions:

Condition	Description
not-index	Page slug is not "index"
has-tags	Page has at least one tag
has-backlinks	Page has backlinks
has-toc	Page has a table of contents

Custom conditions can be registered via:

import { registerCondition } from "quartz/plugins/loader/conditions"

registerCondition("my-condition", (props) => {
  return props.fileData.frontmatter?.myField === true
})

Per-Page-Type Overrides

The layout.byPageType section allows overriding the layout for specific page types:

layout:
  byPageType:
    "404":
      positions:
        beforeBody: [] # No beforeBody components on 404
        left: [] # No left sidebar on 404
        right: [] # No right sidebar on 404

    folder:
      exclude:
        - reader-mode # No reader-mode on folder pages
      positions:
        right: [] # No right sidebar on folder pages

    tag:
      exclude:
        - reader-mode
      positions:
        right: []

Override resolution: For each page type, the config loader:

1. Starts with the full default layout
2. Removes excluded plugins
3. Rebuilds positions from remaining entries
4. Overwrites positions that have explicit overrides (empty array = clear that position)

---

Component Architecture

QuartzComponent

A QuartzComponent is a Preact function component with optional static resource declarations:

type QuartzComponent = ((props: QuartzComponentProps) => any) & {
  displayName?: string
  css?: StringResource // CSS injected into page
  beforeDOMLoaded?: StringResource // JS that runs before DOM ready
  afterDOMLoaded?: StringResource // JS that runs after DOM ready
}

type QuartzComponentConstructor<Options> = (opts: Options) => QuartzComponent

Props received by every component:

type QuartzComponentProps = {
  ctx: BuildCtx // Build context (config, slugs, etc.)
  externalResources: StaticResources // CSS/JS resources
  fileData: QuartzPluginData // Current page's data (frontmatter, slug, etc.)
  cfg: GlobalConfiguration // Site configuration
  children: (QuartzComponent | JSX.Element)[]
  tree: Node // Current page's hast tree
  allFiles: QuartzPluginData[] // All files (including virtual pages)
}

Component Registry

The ComponentRegistry (quartz/components/registry.ts) is a singleton Map that stores all loaded components. Components are registered under multiple keys for flexible lookup:

1. Fully-qualified: "pluginName/ExportName" (e.g., "explorer/Explorer")
2. Export name: "Explorer" (PascalCase)
3. Plugin name: "explorer" (kebab-case, only if plugin has exactly one component)

The layout builder looks up components by:

1. Plugin name (kebab-case from source URL)
2. Fully-qualified key (source/name)
3. PascalCase conversion of plugin name

Page Rendering

renderPage() in quartz/components/renderPage.tsx:

1. Deep-clones the hast tree (to preserve the cached version)
2. Resolves transclusions (see below)
3. Destructures the layout into Head, header[], beforeBody[], Content, afterBody[], left[], right[], Footer, and frame name
4. Resolves the frame via resolveFrame(frameName) — falls back to DefaultFrame if unset
5. Delegates the inner page structure to frame.render({...all slots...})
6. Wraps the frame output in the stable outer shell: <html> → <Head/> → <body data-slug> → <div id="quartz-root" data-frame={frame.name}> → <Body>
7. Serializes to HTML string via preact-render-to-string

The data-frame attribute on #quartz-root enables CSS targeting per-frame (see Page Frames).

Page Frames

The PageFrame system allows page types to optionally define completely different inner HTML structures (e.g. with/without sidebars, horizontal layouts, minimal chrome) while the outer shell remains stable for SPA navigation.

Architecture

┌──────────────────────────────────────────────────┐
│ <html>                                           │  Stable outer shell
│   <head />                                       │  (never changes)
│   <body data-slug="...">                         │
│     <div id="quartz-root" data-frame="...">      │

Interfaces

interface PageFrame {
  name: string                                     // e.g. "default", "full-width", "minimal"
  render: (props: PageFrameProps) => JSX.Element   // Renders the inner page structure
  css?: string                                     // Optional frame-specific CSS
}

interface PageFrameProps {
  componentData: QuartzComponentProps   // Shared props for all components
  head: QuartzComponent                 // Head component (for completeness)
  header: QuartzComponent[]             // Header slot
  beforeBody: QuartzComponent[]         // Before-body slot
  pageBody: QuartzComponent             // Content component (from PageType)
  afterBody: QuartzComponent[]          // After-body slot
  left: QuartzComponent[]               // Left sidebar components
  right: QuartzComponent[]              // Right sidebar components
  footer: QuartzComponent               // Footer component
}

Built-in Frames

Frame	Name	Description	Used By
DefaultFrame	"default"	Original three-column layout: left sidebar + center (header, beforeBody, content, afterBody) + right sidebar + footer	All page types by default
FullWidthFrame	"full-width"	No sidebars. Single center column spanning full width with header, content, afterBody, and footer	canvas-page
MinimalFrame	"minimal"	No sidebars, no header/beforeBody chrome. Only content + footer	404 page

Frame Resolution Priority

Frames are resolved in the PageTypeDispatcher.resolveLayout() function with this priority chain:

1. YAML config override:  layout.byPageType.<name>.template
2. Page type declaration: pageType.frame (in plugin source)
3. Default:               "default"

This means site authors can override any page type's frame via configuration without touching plugin code:

layout:
  byPageType:
    canvas:
      template: minimal   # Override canvas pages to use minimal frame

Creating Custom Frames

New frames are added in quartz/components/frames/:

1. Create a new .tsx file implementing the PageFrame interface
2. Register it in quartz/components/frames/index.ts → builtinFrames registry
3. Reference it by name in page type plugins or YAML config

// quartz/components/frames/PresentationFrame.tsx
import { PageFrame, PageFrameProps } from "./types"

export const PresentationFrame: PageFrame = {
  name: "presentation",
  render({ componentData, pageBody: Content, footer: Footer }: PageFrameProps) {
    return (
      <>
        <div class="center presentation">
          <Content {...componentData} />
        </div>
        <Footer {...componentData} />
      </>
    )
  },
}

CSS Targeting

The data-frame attribute on #quartz-root enables frame-specific CSS without class conflicts:

// Full-width: single column, no sidebar grid areas
.page[data-frame="full-width"] > #quartz-body {
  grid-template-columns: 1fr;
  grid-template-areas: "center";
}

// Minimal: content-only grid
.page[data-frame="minimal"] > #quartz-body {
  grid-template-columns: 1fr;
  grid-template-areas: "center";
}

SPA Safety

Frame changes between pages are SPA-safe because:

1. The SPA router (micromorph) morphs document.body — it does not hardcode selectors like .center or .sidebar
2. The data-frame attribute updates naturally during the morph
3. CSS grid overrides apply immediately based on the new data-frame value
4. collectComponents() collects components from ALL slots regardless of frame, ensuring all component resources (CSS/JS) are available globally

Source Files

File	Purpose
quartz/components/frames/types.ts	PageFrame and PageFrameProps interfaces
quartz/components/frames/DefaultFrame.tsx	Default three-column layout
quartz/components/frames/FullWidthFrame.tsx	Full-width single-column layout
quartz/components/frames/MinimalFrame.tsx	Minimal content-only layout
quartz/components/frames/index.ts	Frame registry and resolveFrame()

Transclusion

Transclusion (![[page]] syntax) is resolved at render time. The renderTranscludes() function walks the hast tree looking for <blockquote class="transclude"> nodes and replaces them with the target page's content.

Resolution strategy:

1. Look up target slug directly in allFiles
2. If not found, strip the file extension and try again (handles virtual page slugs like CanvasPage.canvas → CanvasPage)
3. Support block references (#^blockId) and header references (#heading)
4. Detect and prevent circular transclusions

Virtual page transclusion: The PageTypeDispatcher populates htmlAst on virtual pages by rendering their Body component via preact-render-to-string and parsing the result with hast-util-from-html. This allows wikilinks like ![[navigation.base]] to inline the virtual page's rendered content.

Plugin entry fields:

Field	Type	Required	Description
source	string	Yes	Git source (e.g., github:quartz-community/plugin-name)
enabled	boolean	Yes	Whether the plugin is active
options	object	No	Plugin-specific options (merged with defaultOptions)
order	number	No	Execution order override (default: 50)
layout	PluginLayoutDeclaration	No	Layout placement for component plugins

Layout declaration fields:

Field	Type	Required	Description
position	"left" | "right" | "beforeBody" | "afterBody"	Yes	Where to place the component
priority	number	Yes	Sort order (lower = first)
display	"all" | "mobile-only" | "desktop-only"	No	Viewport visibility
condition	string	No	Conditional rendering predicate
group	string	No	Flex group name
groupOptions	object	No	Per-component flex options

TypeScript Override

For advanced use cases, quartz.ts can override the YAML-loaded config:

import * as ExternalPlugin from "./.quartz/plugins"

// Override plugin options programmatically
ExternalPlugin.Explorer({
  title: "Explorer",
  folderDefaultState: "collapsed",
  folderClickBehavior: "link",
  useSavedState: true,
})

The config loader first reads quartz.config.yaml, then applies any overrides from quartz.ts.
