## Overview

CAP SFLIGHT is a flight-and-travel management sample with Node and Java CAP service implementations, processor and analytics UIs, and Azure DevOps pipeline examples. The user-facing workflow centers on maintaining travel records and bookings through the processor, with service-side validation and price/status actions; analytics is a separate documented UI branch. The repository also presents reusable CI/CD pipeline patterns, including performance testing and CTMS upload. Some UI, CDS, and pipeline internals are unsampled, so their connections are omitted where the evidence does not establish them.

Main entry points: [`srv/travel-service.js`](https://github.com/jasper07/cap-sflight-devops/blob/main/srv/travel-service.js) (Travel service), [`karma-cap-middleware.js`](https://github.com/jasper07/cap-sflight-devops/blob/main/karma-cap-middleware.js) (CAP test middleware), [`srv/src/main/java/com/sap/cap/sflight/processor/CreationHandler.java`](https://github.com/jasper07/cap-sflight-devops/blob/main/srv/src/main/java/com/sap/cap/sflight/processor/CreationHandler.java) (Travel creation), [`app/travel_processor/webapp/Component.js`](https://github.com/jasper07/cap-sflight-devops/blob/main/app/travel_processor/webapp/Component.js) (Travel processor)
