Event Management Platform

A modern, scalable event management platform built with microservices architecture on AWS.

🏗️ Architecture Overview

This platform follows a microservices architecture with the following services:

• User Management Service - Authentication, user profiles, and role management
• Event Management Service - Event CRUD operations and management
• Booking Service - Ticket reservations and capacity management
• Payment Service - Payment processing with Stripe integration
• Notification Service - Email, SMS, and push notifications
• Search Service - Event discovery and search functionality
• Analytics Service - Business intelligence and reporting

Technology Stack

• Backend: Node.js, TypeScript, AWS Lambda
• Database: Amazon DynamoDB (NoSQL)
• API Gateway: AWS API Gateway v2
• Authentication: Amazon Cognito
• File Storage: Amazon S3 + CloudFront
• Caching: Amazon ElastiCache Redis
• Search: Amazon OpenSearch
• Monitoring: CloudWatch, X-Ray
• Infrastructure: AWS CDK (Infrastructure as Code)

🚀 Quick Start

Prerequisites

• Node.js 18+ and npm
• AWS CLI configured with appropriate permissions
• AWS CDK CLI installed globally: npm install -g aws-cdk

Installation

1. Clone the repository

   git clone <repository-url>
   cd event-management-platform

2. Install dependencies

   npm install

3. Set up environment variables

   cp .env.example .env
   # Edit .env with your configuration

4. Build the project

   npm run build

5. Deploy to AWS

   # Bootstrap CDK (first time only)
   cdk bootstrap
   
   # Deploy all stacks
   npm run cdk:deploy

📋 Development Setup

Local Development

1. Install dependencies

   npm install

2. Set up local environment

   # Copy environment template
   cp .env.example .env.local
   
   # Edit with your local settings
   nano .env.local

3. Run tests

   npm test
   npm run test:coverage

4. Lint and format code

   npm run lint
   npm run format

Environment Configuration

The platform uses AWS Systems Manager Parameter Store for configuration management. For local development, you can use environment variables:

# Required environment variables
AWS_REGION=us-east-1
ENVIRONMENT=dev
JWT_SECRET=your-jwt-secret-here
ENCRYPTION_KEY=your-encryption-key-here
STRIPE_SECRET_KEY=sk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...
