There are three different and super simple microservices in this system and they are chained together in the following sequence:

customer → preference → recommendation

Local Development

Tested with Node.js v18.9.

# Clone the repository locally
git clone git@github.com:redhat-scholars/istio-tutorial.git
cd istio-tutorial

# Install antora dependencies
npm install

# Performs an initial build, then watches adoc files
# and rebuilds the site when they are modified
npm run dev

Open the gh-pages/index.html to see the site. You can refresh to see your changes if you modify adoc files, since the npm run dev script will automatically rebuild the site when it detects changes.
