AzureTodo

a proof of concept todo app using Azure SWA, Container Apps, and Cosmos Database.

Architecture

This application utilizes both GitHub actions and Azure Cloud for hosting and CI/CD.

Azure Static Web Apps

This hosts the static web application (react app using vite: see /packages/todo-website/), user authentication system, and as an API proxy to our Azure Container App.

The static web app system seems to put a reverse proxy in-front of the static web app to provide both the authentication layer (/.auth/**/* handles sessions, headers, etc.) and the API (/api/**/* is routed to the connected backend.) all from the same host.

Azure Container App / Azure Container Environment

This hosts our API (node.js web server using express.js: see /packages/todo-api). Azure Container Apps uses Kubernetes and a number of other services under the hood to function.

The app will scale up/down as needed and can actually scale all the way down to 0 (aka no running app when usage is low over time) to save costs.

Azure Container Registry

This hosts our containers and makes them callable

Azure Cosmos Database

This is used to store data for the application in a cost efficient, geographically distributed, and fast.

Development

start the API
- open /packages/todo-api/
- run npm run start to start the server (TODO: dev server via nodemon)
start the Website
- open /packages/todo-websites
- run npm run azure:dev to the start the Azure SWA emulator & CLI
