[Documentation Index](#documentation-index) --- ## Project Overview ### Mission Statement MetaBuilder is a **declarative, data-driven, multi-tenant application platform** where 95% of functionality is defined through JSON and Lua, not TypeScript. The platform features a 5-level architecture with advanced meta-programming capabilities, functioning as a "platform for building platforms." ### Complexity Classification **Complex Application** with meta-programming capabilities. Levels 4-5 procedurally generate Levels 1-3 from pure data definitions stored in a modular seed system. ### Core Philosophy - **Declarative First**: Everything from pages to workflows defined as data - **Modular**: Clear separation of concerns with isolated, maintainable modules - **Scalable**: Architecture supports massive applications without unwieldy growth - **Procedural**: UI and logic generated from configuration, not hardcoded files --- ## Architecture & Design ### 5-Level Architecture The platform implements a hierarchical level system with progressive access and capabilities: | Level | Role | Purpose | Access | Key Features | |-------|------|---------|--------|--------------| | **L1** | Public | Landing page & login | All users | Public information, login interface | | **L2** | User | Dashboard & user tools | Authenticated users | Personal dashboard, user settings | | **L3** | Admin | Admin panel | Admin role users | System administration, user mgmt | | **L4** | God | Builder & IDE | God role users | Visual page builder, full code access | | **L5** | SuperGod | Multi-tenant management | SuperGod role | Tenant creation, power transfer, cross-level preview | ### Multi-Tenant System Complete multi-tenant support implemented with: - **Tenant Isolation**: Namespace-based data separation for all resources - **Blob Storage**: Multi-tenant file storage with access control and quotas - **Structured Data**: User/page/KV/list data scoped to tenants - **Access Control**: Role-based permissions (owner, admin, member, viewer) - **Storage Quotas**: Limits on blob storage, record counts, data size, list length - **Components**: - `TenantIdentity`: User identity within a tenant - `TenantQuota`: Resource limits and usage tracking - `TenantContext`: Context for all operations - `TenantManager`: Manages tenants, quotas, usage ### Atomic Design Pattern Components organized into three categories following atomic design principles: **Atoms** (~12 components) - Basic UI elements from shadcn/ui - Buttons, inputs, labels, badges, avatars - Stateless or minimal state - Location: `src/components/atoms/` **Molecules** (~10 components) - Groups of 2-5 atoms functioning together - Simple composites with single purpose - Examples: form fields, search bars, card headers - Location: `src/components/molecules/` **Organisms** (~40+ components) - Complex components forming distinct sections - May contain business logic - Examples: data tables, forms, editors, IDE - Location: `src/components/organisms/` **Pages/Levels** (5 components) - Top-level page components (remain at root) - Level1 through Level5 components - Location: `src/components/` --- ## Technology Stack ### Frontend - **React 18+** with TypeScript - **Next.js** framework (migration from Vite mentioned) - **Tailwind CSS** for styling - **shadcn/ui** for component library -

DropdownConfigManager, ThemeEditor - SMTPConfigEditor **UI Features:** - IRCWebchat, IRCWebchatDeclarative - WorkflowEditor, PageRoutesManager - GodCredentialsSettings, ScreenshotAnalyzer - GitHubActionsFetcher, AuditLogViewer ### Component Size Violations **Critical Violations (Exceed 150 LOC):** | Component | Current | Target | Reduction | |-----------|---------|--------|-----------| | GitHubActionsFetcher | 887 LOC | 95 LOC | 89% ↓ | | NerdModeIDE | 733 LOC | 110 LOC | 85% ↓ | | LuaEditor | 686 LOC | 120 LOC | 82% ↓ | | SchemaEditor | 520 LOC | 100 LOC | 80% ↓ | | ComponentConfigDialog | 450 LOC | 90 LOC | 80% ↓ | | PropertyInspector | 380 LOC | 85 LOC | 77% ↓ | | IRCWebchat | 290 LOC | 85 LOC | 70% ↓ | | AuditLogViewer | 210 LOC | 70 LOC | 66% ↓ | **Total Violations:** 8 components, 4,146 LOC over limits ### Code Organization Issues - Components often contain multiple responsibilities - State management scattered across multiple useState hooks - Business logic mixed with UI rendering - Hardcoded configurations in components - Limited reusability across contexts --- ## Development Workflow ### Available Scripts ```bash # Development npm run dev # Start dev server npm run build # Build for production npm run preview # Preview production build # Code Quality npm run lint # Run ESLint npm run lint:fix # Auto-fix linting issues # Testing npm run test # Run tests in watch mode npm run test:unit # Run unit tests once npm run test:unit:ui # UI test runner npm run test:unit:coverage # Coverage report npm run test:e2e # Playwright E2E tests npm run test:e2e:ui # E2E UI runner npm run test:e2e:headed # E2E in headed mode npm run test:all # All tests (unit + e2e) # Database npm run db:generate # Generate Prisma client npm run db:push # Apply schema to database npm run db:migrate # Apply migrations (CI/prod) # GitHub Actions (Local Testing) npm run act # Run workflows locally npm run act:lint # Test lint job npm run act:e2e # Test e2e job # C++ Build npm run cpp:check # Check build dependencies npm run cpp:full # Complete build workflow npm run cpp:build # Build with Ninja npm run cpp:test # Run C++ tests npm run cpp:clean # Clean build artifacts ``` ### Testing Approach - **Unit Tests**: Vitest with UI runner - **E2E Tests**: Playwright with multiple browsers - **Local CI/CD**: Act for testing GitHub Actions locally - **Coverage**: Target 80%+ for critical paths - **Performance**: Size limit enforcement ### Database Migration Path 1. Generate Prisma client: `npm run db:generate` 2. Apply schema: `npm run db:push` 3. Run migrations: `npm run db:migrate` (CI/production) ### Seed Data System - Located in `/src/seed-data/` and package directories - Loaded at application initialization - Package-based organization for modularity - Supports multi-tenant data initialization --- ## Known Issues & Refactoring Needs ### High Priority #### 1. Component Size Violations - 8 components exceed 150 LOC architectural limit - 4,146 total LOC over limits - **Action**: Systematic refactoring with decomposition strategy - **Timeline**: 3 weeks, ~103 hours - **Impact**: Improved modularity, testability, maintainability #### 2. State Management Scatter - Business logic scattered across multiple useState hooks - Duplicated state management patterns - **Action**: Extract to custom hooks and database persistence - **Pattern**: One hook per major feature #### 3. Ephemeral State vs Persistent Data - Component state lost on page reload - Should be database-persisted for: - Editor content (LuaEditor, CodeEditor, SchemaEditor) - Workflow configurations - GitHub Actions cache - **Action**: Implement Prisma models for persistent storage #### 4. Hardcoded Configurations - Colors, column definitions, UI configs in components - **Action**: Move to JSON in database or seed files - **Benefit**: Runtime changes without code deployment ### Medium Priority #### 5. GitHub Actions Integration Complexity - GitHubActionsFetcher: 887 LOC with multiple responsibilities - Components: API fetching, polling, log aggregation, AI analysis - **Refactoring Strategy**: - Create custom hook: `useGitHubActions()` (~50 LOC) - Separate components for tabs/views (~65-85 LOC each) - Extract log aggregation to Lua script - Move analysis cache to Prisma model #### 6. IDE Implementation Incomplete - NerdModeIDE: 733 LOC, partial implementation - Missing: File tree, Git integration, test runner, debugging - **Strategy**: Componentize into smaller focused modules #### 7. Lua Editor Missing Features - LuaEditor: 686 LOC, lacks snippet system integration - No persistent script storage - **Action**: Create LuaSnippetLibrary organism, database models ### Low Priority #### 8. Package System Incomplete - Pre-built packages not implemented - Import/export needs UI polish - Asset handling incomplete --- ## Security Implementation ### Multi-Layer Security Architecture #### Layer 1: ACL (Access Control Layer) - **Role-based permissions**: user, admin, god, supergod - **Operation-level authorization**: create, read, update, delete, list - **Row-level security**: Users can only access their own data - **Configuration**: Pre-configured rules for all entities #### Layer 2: Audit Logging - **Event Logging**: All operations logged with: - User context and timestamp - Operation type and entity - Input parameters (sensitive data excluded) - Success/failure status - Error messages - **Compliance**: Audit trail for compliance requirements #### Layer 3: Credential Security - **SHA-512 Hashing**: All passwords stored as salted hashes - **Never Plaintext**: Credentials never logged or transmitted - **Token-based Sessions**: Secure session tokens for API access #### Layer 4: Input Validation - **Prisma**: Parameterized queries prevent SQL injection - **Schema Validation**: JSON schemas enforce data types - **Lua Sandboxing**: Lua scripts execute in sandboxed environment #### Layer 5: Error Handling - **Safe Failures**: Comprehensive error types - **User-Friendly**: Error messages don't expose internals - **Logging**: Errors logged for debugging ### Security Policies #### Password Requirements - Minimum length enforced - Hash comparison protected from timing attacks - Reset tokens with expiration #### Multi-Tenant Isolation - Automatic namespace scoping - Permission checks on all operations - Quota enforcement per tenant #### Blob Storage Security - Namespace-based isolation - Virtual root directories for path sandboxing - Size limits and file count limits #### Future Protections (Phase 3 - C++ Daemon) - Process isolation - User code never sees database credentials - Query validation and sanitization - Resource limits and quotas --- ## Documentation Index ### Core Documentation TODO: Core doc links below point to docs/reference; update to correct paths under docs/ (README, PRD, SECURITY). | File | Purpose | |------|---------| | [INDEX.md](INDEX.md) | Navigation hub for all documentation | | [README.md](README.md) | Project overview and quick start | | [PRD.md](PRD.md) | Product requirements and features (599 lines) | | [SECURITY.md](SECURITY.md) | Security policies and best practices | ### Implementation Guides | File | Purpose | |------|---------| | [implementation/ATOMIC_DESIGN.md](implementation/ATOMIC_DESIGN.md) | Component organization principles | | [implementation/MULTI_TENANT_SYSTEM.md](implementation/MULTI_TENANT_SYSTEM.md) | Multi-tenancy architecture (446 lines) | | [implementation/PRISMA_IMPLEMENTATION_COMPLETE.md](implementation/PRISMA_IMPLEMENTATION_COMPLETE.md) | Database layer implementation | | [implementation/COMPONENT_MAP.md](implementation/COMPONENT_MAP.md) | Complete component classification | | [implementation/DBAL_INTEGRATION.md](implementation/DBAL_INTEGRATION.md) | DBAL integration guide | ### Refactoring & Strategy | File | Purpose | |------|---------| | [REFACTORING_STRATEGY.md](REFACTORING_STRATEGY.md) | Comprehensive refactoring plan (858 lines) | | [REFACTORING_QUICK_REFERENCE.md](REFACTORING_QUICK_REFERENCE.md) | Quick refactoring guide (485 lines) | | [REFACTORING_CHECKLIST.md](REFACTORING_CHECKLIST.md) | Refactoring task checklist | ### Database & DBAL | File | Purpose | |------|---------| | [dbal/README.md](../dbal/README.md) | DBAL architecture and overview | | [dbal/QUICK_START.md](../dbal/QUICK_START.md) | DBAL 5-minute quick start | | [dbal/PROJECT.md](../dbal/PROJECT.md) | DBAL project structure | | [dbal/IMPLEMENTATION_SUMMARY.md](../dbal/IMPLEMENTATION_SUMMARY.md) | Phase 2 DBAL implementation summary | | [dbal/AGENTS.md](../dbal/AGENTS.md) | Agent development guide for DBAL | | [dbal/PHASE2_COMPLETE.md](../dbal/PHASE2_COMPLETE.md) | Phase 2 completion status | ### Development Guides | Directory | Contents | |-----------|----------| | [guides/](guides/) | Quick references and setup instructions | | [builds/](builds/) | C++ build and cross-platform compilation | | [deployments/](deployments/) | Docker, CI/CD, Nginx integration | | [troubleshooting/](troubleshooting/) | Debugging guides and diagnostics | | [migrations/](migrations/) | Data migrations and refactoring | ### Archive & Reference | Directory | Contents | |-----------|----------| | [archive/](archive/) | Completed phases and historical work | | [reference/](reference/) | API references and technical specs | | [database/](database/) | Database design and schemas | | [lua/](lua/) | Lua scripting documentation | | [packages/](packages/) | Package system documentation | --- ## Key Integration Points ### 1.
