Implement GraphQL API alongside REST API

Summary

This PR implements a comprehensive GraphQL API that runs alongside the existing REST API, providing flexible data queries, real-time subscriptions, and enhanced developer experience.

Features Implemented

🚀 Core GraphQL Features

  • Complete Schema: All REST endpoints covered with GraphQL equivalents
  • Query Resolvers: Vaults, beneficiaries, claims, and admin operations
  • Mutation Resolvers: Full CRUD operations with validation
  • Real-time Subscriptions: Live updates for vault changes, claims, and withdrawals
  • Apollo Server Integration: WebSocket support for subscriptions

🔐 Security & Performance

  • Authentication Middleware: Role-based access control (admin/user/public)
  • Rate Limiting: Operation-specific limits with role-based tiers
  • Input Validation: Comprehensive error handling and validation

📚 Documentation & Testing

  • Migration Guide: Step-by-step guide from REST to GraphQL
  • Schema Documentation: Complete API documentation with examples
  • Test Suites: Comprehensive tests for resolvers and subscriptions
  • GraphQL Playground: Interactive testing interface

🔧 Technical Implementation

  • Dependencies: Added Apollo Server, GraphQL, and supporting packages
  • Integration: Seamless integration with existing Express app
  • Backward Compatibility: REST API continues to work unchanged

Files Added/Modified

New GraphQL Implementation

  • src/graphql/schema.ts - Complete GraphQL schema
  • src/graphql/resolvers/ - Query and mutation resolvers
  • src/graphql/subscriptions/ - Real-time subscription handlers
  • src/graphql/middleware/ - Authentication and rate limiting
  • src/graphql/server.ts - Apollo Server setup and integration

Documentation

  • docs/graphql/migration-guide.md - REST to GraphQL migration guide
  • docs/graphql/schema-documentation.md - Complete schema documentation

Testing

  • src/graphql/tests/resolvers.test.ts - Resolver tests
  • src/graphql/tests/subscriptions.test.ts - Subscription tests

Configuration

  • package.json - Added GraphQL dependencies
  • src/index.js - Integrated GraphQL server with Express

Acceptance Criteria Met

GraphQL Query Efficiency: Returns requested data efficiently
Real-time Subscriptions: Live updates delivered via WebSocket
Interactive Testing: GraphQL Playground available at /graphql
Authentication: Respects user permissions and roles
Migration Guide: Comprehensive REST to GraphQL transition guide
Rate Limiting: Prevents abuse with operation-specific limits
Testing: All GraphQL features thoroughly tested

How to Test

  1. Start the server: npm start
  2. Visit GraphQL Playground: http://localhost:3000/graphql
  3. Try sample queries from documentation
  4. Test real-time subscriptions with WebSocket clients

Breaking Changes

None - this is additive functionality. REST API remains fully functional.
