The main purpose of this project is to dockerize a simple NodeJS application and establish a development/production workflow using Docker and NodeJS.
git clone https://github.com/quan0401/node_with_docker
cd node_with_docker
npm run dev # If NodeJS is already installedIf NodeJS is not installed, consider installing it, as we aim to learn Docker and NodeJS together.
