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/

Design Principles

  1. Language Agnostic: API contracts defined in YAML
  2. Security First: C++ daemon sandboxes database access
  3. Development Speed: TypeScript for rapid iteration
  4. Zero Trust: User code never touches DB credentials
  5. Capability-based: Adapters declare support (transactions, joins, etc.)
  6. Testable: Shared test vectors ensure behavioral consistency

  • 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

Key Integration Points

1. DBAL Integration with MetaBuilder

Import pattern:

import { getDBALClient } from '@/lib/dbal-client'

const client = getDBALClient(currentUser, session)

Usage:

// CRUD operations
const user = await client.users.create({ ... })
const users = await client.users.list({ filter: {...} })
await client.users.update(id, {...})
await client.users.delete(id)

2. Component Registration System

Components registered in package catalog with:

  • JSON configuration
  • Lua scripts for behavior
  • Property schema definitions
  • UI layout definitions

3. Workflow Engine

Workflows stored as JSON with:

  • Node definitions
  • Edge connections
  • Lua script integration
  • Execution context

4. Package System

Each package contains:

  • Seed data directory
  • Components (JSON + Lua)
  • Scripts and utilities
  • Static content (assets)
  • Manifest with metadata
