Conditional Logic

Component Library Authentication

Check parameter: include_component_library

If "yes": Replace {{COMPONENT_LIBRARY_AUTH}} with:

RUN --mount=type=secret,id=vite_access_token \
export VITE_ACCESS_TOKEN=$(cat /run/secrets/vite_access_token) && \
echo "@RoyalAholdDelhaize:registry=https://npm.pkg.github.com" > .npmrc && \
echo "//npm.pkg.github.com/:_authToken=${VITE_ACCESS_TOKEN}" >> .npmrc

If "no": Replace {{COMPONENT_LIBRARY_AUTH}} with empty string (remove lines)

Note: RUN npm install is always present after the placeholder, regardless of component library choice.

Key Features

• Base image: Ubuntu Node.js 22 LTS from Azure Container Registry
• Quality checks: Runs lint, stylelint, and unit tests during build
• Nginx: Installs and configures nginx for serving static files
• Security: Runs as non-root user (nodejs_svc)
• Port: Exposes 8080
• Optimization: Cleans apt cache to reduce image size

Notes

• All configuration values are production-ready defaults
• Build fails if quality checks don't pass
• Component library authentication uses Docker secrets for security
• References nginx configuration files created by nginx skills
