## 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:
```json
{
"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
├── .eslintrc.json
├── .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
```typescript
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)
body: QuartzComponentConstructor // The Body component for rendering page content
}
```
### Matchers
The `matchers.ts` module provides composable matcher factories:
```typescript
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:
```typescript
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
<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).
```yaml
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.
```yaml
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:
```yaml
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:
```yaml
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:
```typescript
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:
```yaml
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:
```typescript
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:**
```typescript
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
4. Renders the full HTML document as a Preact JSX tree
5. Serializes to HTML string via `preact-render-to-string`
### 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:
```typescript
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`.
