This repository contains examples for integrating microservices:

• Integration of frontend components via a micro-frontend approach
• Integration of backend data via Apache Kafka based events

The example consists of the following services:

• composer - a basic frontend composition engine
• product-detail-page - a simple product detail page
• header-footer - a service serving a header and a footer
• product-information - a backend for managing product data

To run the example, each project can be build using the latest maven version:

mvn clean install

All projects can be build via ./build.sh - this will build jars and docker images for all services.

All services together can be started via docker-compose up -d.

Locally, the services will run on the following ports:

• composer: 8000
• product-detail-page: 8080
• header-footer: 8081
• product-information: 8082

When started via docker-compose, the services run on

• composer: 9500
• product-detail-page: 9080
• header-footer: 9081
• product-information: 9082

To test the setup, go to http://localhost:9500/p/2670536 to see a product detail page including a header and a footer. To acess the product detail page directly, go to http://localhost:9080/products/2670536.
