Deploying a Web App with Azure App Service

Azure App Service is a fully-managed PaaS for hosting web apps and APIs, you push your code, Azure handles the servers, scaling, and patching.

az webapp up \
  --name kodstigen-demo-app \
  --resource-group kodstigen-rg \
  --runtime "NODE:20-lts"

az webapp up is a convenience command, it creates an App Service plan and web app if they don't exist yet, then deploys your current folder's code to it in one step.

Key concepts

• An App Service Plan defines the underlying compute (how much CPU/RAM, how many instances), think of it as the "size" of the box your app runs in.
• A Web App is the actual application running on that plan, you can run multiple web apps on one plan.
• Once deployed, your app is reachable at https://<app-name>.azurewebsites.net.

az webapp log tail --name kodstigen-demo-app --resource-group kodstigen-rg

log tail streams your app's live logs, the first thing to check when a deployment doesn't behave as expected.
