📝 Walkthrough

Walkthrough

This pull request introduces a complete Node.js/Express appointment booking API with MongoDB persistence. It establishes core application infrastructure, authentication/authorization flows, database configuration, logging, and nine modular domain features (auth, users, providers, services, appointments, availability, reviews, notifications, admin) each with models, controllers, services, routes, and validation layers.

Changes

Cohort / File(s)	Summary
Configuration & Setup .env.example, .gitignore, package.json, eslint.config.cjs	Project configuration including environment templates, Git ignore rules, npm dependencies/scripts, and linting setup.
Documentation docs/auth.md, docs/user.md	API endpoint documentation covering authentication (register, login, logout) and user operations (get, update, delete) with request/response examples.
Application Core src/app.js, src/server.js	Express app initialization with middleware stack (helmet, CORS, rate limiting, JSON parsing) and route mounting. Server entry point that connects to database before listening.
Configuration Modules src/shared/config/env.config.js, src/shared/config/db.config.js	Environment variable validation via Zod schema and MongoDB connection setup with Mongoose, connection event listeners, and graceful shutdown handlers.
Shared Utilities src/shared/utils/helpers.js, src/shared/utils/logger.js	Helper classes (ApiResponse, AppError, asyncHandler) and Winston logger with rotating file transports, process error handlers, and sensitive field redaction.
Authentication Middleware src/shared/middleware/auth.middleware.js, src/shared/middleware/error.middleware.js, src/shared/middleware/validate.middleware.js, src/shared/middleware/rateLimit.middleware.js, src/shared/middleware/index.js	JWT verification and role-based access control (protect, restrictTo), centralized error handling with development/production responses, request validation via Zod schemas, and in-memory rate limiting by IP address.
Auth Module src/modules/auth/auth.model.js, src/modules/auth/auth.controller.js, src/modules/auth/auth.service.js, src/modules/auth/auth.routes.js, src/modules/auth/auth.validation.js, src/modules/auth/index.js	User registration, login, token refresh, profile retrieval/update with bcrypt password hashing, JWT token generation, and credential verification. Routes for /register, /login, /refresh, /logout, and profile endpoints.
Users Module src/modules/users/user.model.js, src/modules/users/user.controller.js, src/modules/users/user.service.js, src/modules/users/user.routes.js, src/modules/users/user.validation.js, src/modules/users/index.js	User CRUD operations with self and admin views. /me endpoints for profile management; admin endpoints for user listing/updates/deletion with role enforcement.
Providers Module src/modules/providers/provider.model.js, src/modules/providers/provider.controller.js, src/modules/providers/provider.service.js, src/modules/providers/provider.routes.js, src/modules/providers/provider.validation.js, src/modules/providers/index.js	Provider profile management linked to users. Creation restricted to provider/admin roles. Includes approval workflow and provider-specific data (business name, specialty, location, approval status).
Services Module src/modules/services/service.model.js, src/modules/services/service.controller.js, src/modules/services/service.service.js, src/modules/services/service.routes.js, src/modules/services/service.validation.js, src/modules/services/index.js	Service catalog CRUD. Services linked to providers with name, description, category, duration, price, and active status. Provider-scoped management via req.user authorization checks.

Includes MongoDB transactions for state consistency, availability slot reservation, conflict detection, optional rescheduling, and notification triggers. Extensive service logic for complex workflows.
Availability Module src/modules/availability/availability.model.js, src/modules/availability/availability.controller.js, src/modules/availability/availability.service.js, src/modules/availability/availability.routes.js, src/modules/availability/availability.validation.js, src/modules/availability/index.js	Provider time-slot management with recurrence support, booking capacity tracking, and bulk operations.
