Getting Started Todo App

This project provides a sample todo list application. It demonstrates all of the current Docker best practices, ranging from the Compose file, to the Dockerfile, to CI (using GitHub Actions), and running tests. It's intended to be a well-documented to ensure anyone can come in and easily learn.

Application architecture

This sample application is a simple React frontend that receives data from a Node.js backend.

When the application is packaged and shipped, the frontend is compiled into static HTML, CSS, and JS and then bundled with the backend where it is then served as static assets. So no... there is no server-side rendering going on with this sample app.

During development, since the backend and frontend need different dev tools, they are split into two separate services. This allows Vite to manage the React app while nodemon works with the backend. With containers, it's easy to separate the development needs!

Development

To spin up the project, simply install Docker Desktop and then run the following commands:

git clone https://github.com/docker/getting-started-todo-app
cd getting-started-todo-app
docker compose up -d

You'll see several container images get downloaded from Docker Hub and, after a moment, the application will be up and running! No need to install or configure anything on your machine!

Simply open to http://localhost to see the app up and running!

Any changes made to either the backend or frontend should be seen immediately without needing to rebuild or restart the containers.

To help with the database, the development stack also includes phpMyAdmin, which can be access at http://db.localhost (most browsers will resolve *.localhost correctly, so no hosts file changes should be required).

Tearing it down

When you're done, simply remove the containers by running the following command:

docker compose down
