Adding a Swagger UI to Your SAP Cloud Application Programming Model / Node.js ServiceAdding a Swagger UI to Your SAP Cloud Application Programming Model / Node.js ServiceThe problem stated from the other side of the wire: a CAP and HANA backend consumed by frontend developers with no SAP background, who said in the first meeting that they could not work from what the service offered. A browsable API page is the answer, and this is the post the Swagger UI plugin indexed here exists to serve.published 2020-01-23

Working with the Attachment plugin - Cloud Application ProgrammingWorking with the Attachment plugin - Cloud Application ProgrammingOne instalment of the author's own series working through the CAP plugins one at a time, and it reads as that: what the plugin does, how it does it, and how to put it in a service. Written from the plugin list in capire rather than from a problem, which makes it the plainest introduction here.published 2024-05-18

Performance Boost and Caching Strategy for Faster Data Access using "cds-caching" in SAP CAPPerformance Boost and Caching Strategy for Faster Data Access using "cds-caching" in SAP CAPSomebody else's account of using the plugin, which is the useful counterpart to its documentation. The case is specific: a master-data entity of more than a million rows, rarely written and constantly read, where the read-heavy shape is what makes caching worth the complexity rather than a general performance wish. Walks through integrating cds-caching into that application and what it changed.NaveenChandar, published 2025-03-04

PostgreSQL persistence adapter for CAP (Node.js)PostgreSQL persistence adapter for CAP (Node.js)The contradiction the adapter was built to resolve, stated plainly in 2020: CAP's core is open, non-intrusive and platform-agnostic, which is what would let it run outside SAP's world — except that HANA was the only officially supported production persistence and HANA exists only inside BTP. cds-pg is the answer to that, and this is the post that argues for it. Read now as the front end of a story whose other end is the 2023 post recording cds-pg's deprecation in favour of @cap-js/postgres.published 2020-08-20

Building Durable AI Agents - Announcing the cds-langgraph-persistence PluginBuilding Durable AI Agents - Announcing the cds-langgraph-persistence PluginThe announcement, and the argument behind it. Treating an agent as a software architecture rather than a model with tools makes a list of production requirements — identity, authn and authz, multitenancy, persistence, event-driven flows, scalability, observability, CI/CD — and the author's point is that CAP already answers most of them for BTP, which is what makes LangGraph inside CAP Node.js worth doing. The post then narrows to one of those requirements, durability, and the checkpointer that supplies it. Written from a year of building agents next to real business systems rather than as a framework tour.merbinjanselm, published 2026-07-15

CDS-TS-Dispatcher: Simplifying SAP CAP TypeScript DevelopmentCDS-TS-Dispatcher: Simplifying SAP CAP TypeScript DevelopmentThe first of a pair introducing the author's own libraries, and it states what it is reacting to: CAP derives OData services from a CDS model, but the communication between business logic, service and persistence layers is left to you, and the earlier attempt at the service-layer half, cds-routing-handler, appeared unmaintained against newer CAP. The dispatcher is the answer offered for that layer.published 2023-11-13

CDS-TS-Repository: Simplify SAP CAP Entity persistance with BaseRepositoryCDS-TS-Repository: Simplify SAP CAP Entity persistance with BaseRepositoryThe persistence half of the same pair, three days later: a BaseRepository putting entity access behind a typed repository rather than CQN written inline in a handler. Shares its opening argument with the dispatcher post — the layer between business logic and persistence is the part CAP leaves open — and the two are designed to be used together.published 2023-11-16

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
