Node.js is a JavaScript runtime for building web applications. This guide shows you how to containerize a TypeScript Node.js application with a React frontend and PostgreSQL database.
The sample application is a modern full-stack Todo application featuring:
- Backend: Express.js with TypeScript, PostgreSQL database, and RESTful API
- Frontend: React.js with Vite and Tailwind CSS 4

What will you learn?
In this guide, you will learn how to:
- Containerize and run a Node.js application using Docker.
- Run tests inside a Docker container.
- Set up a development container environment.
- Configure GitHub Actions for CI/CD with Docker.
- Deploy your Dockerized Node.js app to Kubernetes.
To begin, you’ll start by containerizing an existing Node.js application.
Prerequisites
Before you begin, make sure you're familiar with the following:
- Basic understanding of JavaScript and TypeScript.
- Basic knowledge of Node.js, npm, and React for modern web development.
- Understanding of Docker concepts such as images, containers, and Dockerfiles. If you're new to Docker, start with the Docker basics guide.
