khentdev/DockerPracticeLearnings ? reverse-engineered prompt

Build me a simple todo app backend I can use to practice Docker.

I want a small TypeScript project that runs in containers and helps me understand the basics like building an image, starting the app with Docker Compose, using a volume for data, and making sure the app can talk to its database or storage properly. Keep it simple and practical, something like a basic todo API where I can create, read, update, and delete tasks.

Please make it easy to run from scratch with clear instructions, and set it up so I can learn by changing things and seeing what breaks. If you need to check current Docker or TypeScript docs online, go ahead. I mainly want a clean example that is realistic enough to teach me how containers, networking, and persistence work without being too complicated.
