Given the difficulty of finding a job, I decided to embark on a new project that we will explore here on the site. The goal is to incorporate all my learning in TypeScript, React, Node, CI/CD, AWS, Docker, Terraform, CA, SOLID, and DDD into a simple yet comprehensive project, making it easier to review each part of the code.

Project Organization

• Monorepo Structure:

  • Utilize Turborepo to manage all project requirements.

• Backend:

  • Use Nest.js for building the server-side application.

• Frontend:

  • Use Next.js along with Shadcn/ui to streamline the project setup, avoiding the need to reinvent the wheel.

• Domain Layer:

  • Create an isolated domain layer containing entities, use cases, and interfaces for repositories and services.
  • Implement these components later in the infrastructure layers following the Dependency Inversion Principle (DIP) of SOLID.
  • Adhere to Test-Driven Development (TDD) to ensure the code is testable and secure from the outset.

• Testing:

  • Use Vitest and Playwright for comprehensive testing.
  • Orchestrate all tests, leveraging the benefits of a monorepo setup, both during development and in CI/CD pipelines using GitHub Actions.

• Containerization and Deployment:

  • Containerize the entire application with Docker.
  • Publish Docker images to Docker Hub and AWS Elastic Container Registry (ECR).
  • Deploy applications to AWS App Runner.

• Infrastructure as Code (IaC):

  • Orchestrate all AWS infrastructure directly from the IaC package within the monorepo.
  • Use Terraform to provision AWS resources such as ECR, App Runner, database, and Redis for cache management and rate limiting.

The choice of a simple Todo App project allows the focus to remain on the development methodology and architecture rather than the complexity of the application itself, with a significant emphasis on the CI/CD pipeline.

Follow along with the evolution of this project. This post was a summary of what will be built, and future posts will cover each stage of the project's construction in detail.
