simple-todo

A very simple todo app, with styles from todomvc.com. Created as a tool for demonstration of deployment capabilities, specifically with Kubernetes.

Design

simple-todo is a very basic Express app, with a Mysql backend and some basic jquery to facilitate the single-page frontend. The UI allows you to:

• Enter a new todo
• Mark a todo as complete
• Delete a todo

If connected to a mysql database, the app will load todos on page load. The app will sync todos with the mysql database each time you change the data in the UI.

simple-todo has been designed specifically to work seamlessly without a database connection. The user will notice errors in the browser console, marking attempts to sync with the database. Without a database connection, refreshing the page will also erase all todos.

To Run Locally

$ npm i

Start the mysql database (and an adminer instance):

Using Docker

Build the app image:
