The goal is to reduce tight coupling between transformers, filters, emitters, and components, enabling better modularity, maintainability, and extensibility. The decoupling will standardize data exchange through the `vfile` data property while minimizing direct dependencies on utility functions and other plugins. + +## 1. Current State Analysis + +### 1.1 Plugin Architecture Overview + +Quartz currently has three main plugin types: + +1. **Transformers** (`QuartzTransformerPlugin`): Transform markdown/HTML content during the build process + - Can provide `textTransform`, `markdownPlugins`, `htmlPlugins`, and `externalResources` + - Examples: FrontMatter, TableOfContents, CrawlLinks, ObsidianFlavoredMarkdown + +2. **Filters** (`QuartzFilterPlugin`): Determine which content should be published + - Implement `shouldPublish` method + - Examples: RemoveDrafts, ExplicitPublish + +3. **Emitters** (`QuartzEmitterPlugin`): Generate output files from processed content + - Implement `emit` and optionally `partialEmit` methods + - Can provide `getQuartzComponents` and `externalResources` + - Examples: ContentPage, ComponentResources, Assets, ContentIndex + +### 1.2 Current Data Flow + +``` +Content Files → Transformers → Filters → Emitters → Output Files + ↓ ↓ ↓ + vfile.data vfile.data vfile.data +``` + +### 1.3 Identified Coupling Issues + +#### 1.3.1 Direct Utility Dependencies + +**Issue**: Plugins are tightly coupled to utility modules in `quartz/util/`: + +- **Path utilities** (`util/path.ts`): Nearly all plugins import path manipulation functions + - `slugifyFilePath`, `simplifySlug`, `transformLink`, `splitAnchor`, `pathToRoot` + - Used in: all transformers, most emitters + +- **Resource utilities** (`util/resources.tsx`): Emitters depend on resource management + - `StaticResources`, `JSResource`, `CSSResource` + - Used in: ComponentResources, all page emitters + +- **BuildCtx** (`util/ctx.ts`): Shared context passed to all plugins + - Contains: `argv`, `cfg`, `allSlugs`, `allFiles`, `buildId`, `incremental` + - Provides global state access to all plugins + +**Impact**: +- Changes to utility functions require updates across many plugins +- Hard to test plugins in isolation +- Difficult to version or swap utility implementations + +#### 1.3.2 Cross-Plugin Dependencies + +**Issue**: Plugins directly import and depend on other plugins: + +- **Component dependencies in transformers**: + - `transformers/ofm.ts` imports component scripts: `callout.inline`, `checkbox.inline`, `mermaid.inline` + - Creates tight coupling between content transformation and UI components + +- **Plugin data dependencies**: + - Emitters access data set by specific transformers (e.g., `toc`, `links`, `frontmatter`) + - No formal contract for what data transformers provide + - Breaking changes in one transformer can break dependent emitters/components + +**Impact**: +- Cannot reorder or remove plugins without checking dependencies +- Difficult to create alternative implementations +- Hidden dependencies make refactoring risky + +#### 1.3.3 Component-Plugin Coupling + +**Issue**: Bidirectional dependencies between components and plugins: + +- **Components depend on plugin data**: + - `components/Date.tsx`, `components/PageList.tsx` import `QuartzPluginData` + - `components/scripts/explorer.inline.ts` imports `ContentDetails` from `emitters/contentIndex` + +- **Plugins depend on components**: + - `emitters/componentResources.ts` imports component scripts and styles + - `emitters/contentPage.tsx` imports layout components + +- **Emitters construct component instances**: + - `getQuartzComponents()` method creates tight coupling between emitters and components + +**Impact**: +- Cannot change component interface without updating plugins +- Cannot swap rendering engines easily +- Component reusability is limited + +#### 1.3.4 VFile Module Augmentation Pattern + +**Issue**: Plugins extend the `vfile` DataMap through module augmentation: + +Current approach (7 augmentations found): +```typescript +declare module "vfile" { + interface DataMap { + links: SimpleSlug[] + toc: TocEntry[] + frontmatter: { ... } + // etc. + } +} +``` + +**Problems**: +- No central registry of available data properties +- Type declarations scattered across plugin files +- No validation that required data exists +- Difficult to track data flow between plugins + +**Impact**: +- Hard to understand what data is available at each stage +- No compile-time guarantees about data presence +- Plugin authors must read all transformer code to know available data + +#### 1.3.5 BuildCtx as Global State + +**Issue**: `BuildCtx` provides global mutable state: + +```typescript +interface BuildCtx { + buildId: string + argv: Argv + cfg: QuartzConfig + allSlugs: FullSlug[] // Mutable array + allFiles: FilePath[] // Mutable array + trie?: FileTrieNode + incremental: boolean +} +``` + +**Problems**: +- Plugins can mutate `allSlugs` array (seen in FrontMatter plugin) +- Side effects not clearly tracked +- Difficult to parallelize plugin execution +- Hard to test plugins without full BuildCtx + +**Impact**: +- Race conditions in concurrent scenarios +- Unpredictable plugin behavior +- Testing requires complex mocking + +### 1.4 Dependency Graph Analysis + +``` +Plugins Layer +├── Transformers +│ ├── → util/path (high coupling) +│ ├── → util/escape (medium coupling) +│ ├── → components/scripts (medium coupling) +│ └── → vfile.data (correct pattern) +│ +├── Filters +│ ├── → util/path (low coupling) +│ └── → vfile.data (correct pattern) +│ +└── Emitters + ├── → util/path (high coupling) + ├── → util/resources (high coupling) + ├── → util/theme (medium coupling) + ├── → components/* (high coupling) + ├── → other emitters (low coupling) + └── → vfile.data (correct pattern) + +Components Layer +├── → plugins/vfile (high coupling) +├── → plugins/emitters (medium coupling) +└── → util/path (medium coupling) +``` + +### 1.5 Current Strengths + +Despite coupling issues, the current architecture has strengths to preserve: + +1. **VFile-based data passing**: Using `vfile.data` for inter-plugin communication is sound +2. **Plugin instance pattern**: Functional plugin factories with options are flexible +3. **Unified processing**: Using unified/remark/rehype ecosystem is appropriate +4. **Type safety**: TypeScript provides good type checking for plugin interfaces +5. **Clear plugin categories**: Separation into transformers/filters/emitters is logical + +## 2. Decoupling Goals + +### 2.1 Primary Objectives + +1. **Isolate plugin logic**: Each plugin should be independently testable +2. **Minimize shared dependencies**: Reduce coupling to utility modules +3. **Standardize data contracts**: Formalize vfile data schema +4. **Remove cross-plugin imports**: Eliminate direct plugin-to-plugin dependencies +5. **Decouple components**: Separate component definitions from plugin logic + +### 2.2 Non-Goals + +1. **Not** changing the unified/remark/rehype pipeline architecture +2. **Not** removing the BuildCtx concept entirely (it provides necessary context) +3. **Not** breaking the transformer → filter → emitter processing order +4. **Not** requiring complete rewrites of existing plugins (incremental migration) + +## 3.

Created centralized vfile-schema.ts with all VFile data type definitions - Created plugin-context.ts with PluginUtilities abstraction layer - Created test-helpers.ts for plugin testing utilities - Made BuildCtx readonly to prevent plugin mutations - Added MutableBuildCtx for build orchestration layer - Updated components to not mutate ctx.trie - Updated FrontMatter plugin with temporary cast for backward compatibility - Updated TransformOptions to accept ReadonlyArray Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> * feat: add plugin utilities to BuildCtx and document plugin decoupling - Added utils property to BuildCtx with createPluginUtilities() - Documented plugin data dependencies with JSDoc comments on transformers and filters - Created comprehensive plugin migration guide in docs/PLUGIN_MIGRATION.md - Updated plugin types.ts with guidance on using PluginContext - All plugins now have access to ctx.utils for path, resource, and escape utilities Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> * docs: add implementation and security summaries - Created IMPLEMENTATION_SUMMARY.md documenting all phases completed - Created SECURITY_SUMMARY.md with CodeQL scan results - All security checks passed with 0 vulnerabilities - Complete documentation of changes, decisions, and impact Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> * docs: add guidance for custom plugins extending vfile data - Added section "Adding Custom VFile Fields" to PLUGIN_MIGRATION.md - Demonstrates TypeScript module augmentation for custom fields - Shows best practices for extending vfile data in third-party plugins - Clarifies that centralized schema doesn't prevent custom extensions Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> * refactor: address code review feedback - Remove `any` type annotations from component map callbacks (Breadcrumbs, FolderContent) - Fix test-helpers: change `config` to `cfg` to match BuildCtx interface - Add `trie: undefined` to mock context for completeness - Add missing vfile fields to schema: text, blocks, htmlAst, hasMermaidDiagram - Make Argv properties truly readonly with ReadonlyArgv type - Add documentation explaining module augmentation pattern is intentional - Document FrontMatter mutation as known technical debt with timeline Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: saberzero1 <8161064+saberzero1@users.noreply.github.com> --- DESIGN_DOCUMENT_DECOUPLING.md | 141 ++++++--- docs/IMPLEMENTATION_SUMMARY.md | 329 +++++++++++++++++++++ docs/PLUGIN_MIGRATION.md | 237 +++++++++++++++ docs/SECURITY_SUMMARY.md | 96 ++++++ quartz/build.ts | 10 +- quartz/components/Breadcrumbs.tsx | 2 +- quartz/components/pages/FolderContent.tsx | 2 +- quartz/plugins/filters/draft.ts | 8 + quartz/plugins/filters/explicit.ts | 8 + quartz/plugins/plugin-context.ts | 91 ++++++ quartz/plugins/test-helpers.ts | 132 +++++++++ quartz/plugins/transformers/frontmatter.ts | 17 +- quartz/plugins/transformers/links.ts | 9 + quartz/plugins/transformers/toc.ts | 11 + quartz/plugins/types.ts | 8 + quartz/plugins/vfile-schema.ts | 110 +++++++ quartz/util/ctx.ts | 19 ++ quartz/util/path.ts | 2 +- 18 files changed, 1180 insertions(+), 52 deletions(-) create mode 100644 docs/IMPLEMENTATION_SUMMARY.md create mode 100644 docs/PLUGIN_MIGRATION.md create mode 100644 docs/SECURITY_SUMMARY.md create mode 100644 quartz/plugins/plugin-context.ts create mode 100644 quartz/plugins/test-helpers.ts create mode 100644 quartz/plugins/vfile-schema.ts diff --git a/DESIGN_DOCUMENT_DECOUPLING.md b/DESIGN_DOCUMENT_DECOUPLING.md index cb3f6e45b..ce6ea82cb 100644 --- a/DESIGN_DOCUMENT_DECOUPLING.md +++ b/DESIGN_DOCUMENT_DECOUPLING.md @@ -40,16 +40,15 @@ Content Files → Transformers → Filters → Emitters → Output Files -
