Containerized development with NestJS and Docker

Creating a new NestJS application is simplified with its CLI, which generates a ready-to-go setup with a single command. However, as applications grow in complexity and require external services like Postgres or Redis, setting up a consistent development environment across different machines can become challenging. Docker containerization is recommended to ensure applications run consistently across various environments by automatically setting up these dependencies during startup. Using Docker's multi-stage build feature helps keep the production image slim by separating development dependencies, while docker-compose further enhances local development by coordinating services such as Redis and Postgres. The integration of Visual Studio Code's debugger with this setup can enhance developer productivity by offering live debugging capabilities.
