azure-pipelines.yml

# This pipeline sets the build number using variables from a linked group,
# builds a Node.js application, publishes it, and then deploys it to an Azure Web App,
# updating an app setting with the generated build number.

# The 'name' property defines the format of the build number.
# It uses variables from the linked variable group and $(Rev:r) for a unique revision.
# IMPORTANT: Ensure 'ragfrontend-global-vars' contains MajorVersion, MinorVersion.
