Deploy and Run the Incident Management Application in the SAP BTP, Kyma Runtime with a Mock ServerDeploy and Run the Incident Management Application in the SAP BTP, Kyma Runtime with a Mock ServerBuilds the Incident Management CAP service and its HTML5 UI deployer as container images with the pack CLI's Cloud Native Buildpacks, then deploys both to SAP BTP, Kyma runtime with a Helm chart, wiring in the mock-server destination and productive cds build --production output set up in the prerequisite tutorials. Marked out of maintenance in favour of the newer "Develop a Side-by-Side CAP-Based Extension Application" mission in SAP Discovery Center, but the build-and-deploy mechanics it walks through — buildpacks, image tags, a Helm chart — are what deployment still covers for Kyma.published 2024-12-06

Speed up deployment for CAP using TurborepoSpeed up deployment for CAP using TurborepoImpatience as a method: minutes of waiting on MBT and cf deploy sent the author looking for alternatives. It is fair to MBT first — a wrapper doing the whole deployment in one go, creating services and applications along the way — before showing what Turborepo changes about the build half. The trade it makes is explicit rather than assumed.published 2024-12-06

SQLite as database for a multi-target (/productive) CAP ApplicationSQLite as database for a multi-target (/productive) CAP ApplicationOpens with "Not recommended but possible", and then names the two cases where it is the right call anyway: a showcase, and a landscape with no HANA Cloud available. The caveat is the content.Christopher_Ketzler, published 2024-07-05

Seed dataCommunity only
Avoid design time CAP server restarts when maintaining local data filesAvoid design time CAP server restarts when maintaining local data filescds watch restarting on every file change is the feature; this is the case where it is not. Editing a CSV seed file mid-edit restarts the server against half-finished data, and the post is about suppressing that without giving up the watch loop. A small friction most people work around silently rather than fix.published 2024-04-26

ISO content for common CAP typesISO content for common CAP typesThe npm package that supplies ISO-standard content — countries, languages, currencies, timezones — for CAP's common types, and how it works underneath. The author flags the length and the reason for it up front, having followed the mechanism further than the question required, which is what makes it worth reading rather than a package announcement.published 2024-03-14

SAP CAP: Controller - Service - Repository architectureSAP CAP: Controller - Service - Repository architectureThe pattern the author's two libraries exist to support, set out as a whole rather than one package at a time: a controller layer receiving the request, a service layer holding business logic, and a repository layer owning persistence — the separation CAP leaves to the developer once a model has produced an OData service. Read after the dispatcher and repository posts, or before them as the argument for both.published 2024-04-22

Use TypeScript with the SAP Cloud Application Programming ModelUse TypeScript with the SAP Cloud Application Programming ModelWritten from the position of someone who avoided JavaScript for years and then had to cover CAP, which gives it a useful angle: what TypeScript buys a person arriving from a typed language, and where to start rather than how to finish. Ends on a worked example rather than a survey.KevinR, published 2024-06-24
