Turborepo CDKTF Microservices App

Monorepo using serverless microservices design with AWS Lambda and Amazon MQ (RabbitMQ) for backend, Vercel for frontend (Next.js) with Terraform CDK infrastructure.

What's inside?

This turborepo uses pnpm as a packages manager. It includes the following packages/apps:

Apps and Packages

• csv-to-pdf-microservice: a python microservice that converts csv to pdf with RabbitMQ & kombu (messaging library)
• aggregation: a Nestjs backend for frontend (Lambda function)
• web: Next.js app
• eslint-config-custom: eslint configurations (includes eslint-config-next and eslint-config-prettier)
• tsconfig: tsconfig.jsons used throughout the monorepo

Notes

• The infrastructure targets minimum cost (free) and does not include best practices for security. If you want to use it for large production you should create a VPC with private & public subnets with NAT Gateway (or VPC Endpoint PrivateLink) to establish a connection between API Gateway, Amazon MQ (set publicly accessible to false), STS, SecretsManager, and AWS Lambda. If you use VPC Endpoint (PrivateLink) for communication between these services, the traffic won't go on the public internet, it stays on AWS Network and this will help maximum security for your application.
• Besides requests between microservice and frontend, the file sharing between Lambdas is provided with a message queue. (we are working with files less than 100 KB, and for staying free tier) You should not use a message queue for sharing file binary in large production, instead, you should use a reference path. For a serverless (AWS Lambda) environment, you can use EFS or S3. You can find additional information in application code comments.

Utilities

This turborepo has some additional tools already setup for you:

• TypeScript for static type checking
• ESLint for code linting
• Prettier for code formatting
