It also walks through an @open entity that accepts properties the model never declared, and reading temporal dataTemporal dataKeeping every version of a record that was valid for a period, and reading the one that held at a given moment — the assignment somebody had on the first of March, not the one they have now — without the application filtering time slices by hand.SAP only defined with CAP's temporal aspect, where a plain read returns only what is valid now and a custom handler is needed to retrieve every time slice.Generators

DRY CAP – Making Sustainable Solutions Through PluginspublishedA Devtoberfest 2026 building-apps session on packaging the things you would otherwise write twice, from in-house API clients and shared data models to validation logic, as a CAP plugin. The presenter builds one live: a cds-plugin.js next to package.json is what makes CAP notice the plugin at all, an index.cds carries a reusable user context and service that the consuming application projects into its own and protects there, and the plugin registers an Express middleware at a chosen step of the bootstrap to put user properties on the request. A feature-flagging plugin his team already uses closes it, and the whole walkthrough is the edge to Plugin authoringPlugin authoringWriting a package that extends a framework or runtime rather than an application that uses it — a reusable extension loaded by its host, and the question you arrive at once solving a problem twice makes you want to solve it once for everyone.SAP only.Plugin authoring

@dxfrontier/cds-ts-dispatcherprovides[typescript-patterns] revisedThe edge said only that the package answers the capability. It now says what it contributes — decorators binding handlers, the three layers its documentation recommends, injection between them and the draft decorators — and states the four comparison facets the capability declares, each on the README sentence it rests on.TypeScript patterns
@dxfrontier/cds-ts-repositoryprovides[typescript-patterns] revisedThe edge carried no sentence. It now says which half of the arrangement the package answers, names the two ways its own documentation shows it being used, and states the persistence value of the capability's layers facet. draft_events is left unstated on purpose: BaseRepositoryDraft reads and writes the draft entity, which is not a place to handle the draft events, and stating the flag here would make the two look like the same fact.TypeScript patterns
@neoimpulse/cap-js-bootstrapprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge was a bare reference: the one capability this package answers carried no sentence and no source, which rule 10 does not allow. The package's own npm text names what it starts, cds watch per service and the router through cds bind --exec, and is quoted in its own language. Read through registry.npmjs.org because npmjs.com refuses the fetcher.Local development
@sang2x/captoolsprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. Its own command description states that it writes the resolved VCAP_SERVICES into default-env.json, which is the documented difference against cds bind, where only the place the credentials can be fetched from is stored on the machine. Stated as a fact about the file, with the consequence for a project named in when_not_to_use rather than as a judgement on the tool.Local development

@sap/cds-dkprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge named the hybrid profile without naming cds bind, and the capability's new comparison columns need the sourced answers here: the parts of the local stack this starts, that it binds cloud services, and that only the location of the credentials is stored on the machine, which is the difference against a helper that writes them into a file.Generators
cap-handler-frameworkprovides[typescript-patterns] revisedThe edge carried no sentence while the artifact's own description carried the detail. It now says what the package contributes to this capability — method names as the binding, the generated index the service reads, the separate draft hooks and the shared context — and states handler_binding, dependency_injection and draft_events on the README sentences they rest on. The layers facet is left unstated: the feature list read today names no layer above the handlers.TypeScript patterns
cds-plugin-handlersprovides[typescript-patterns] revisedThe edge carried no sentence. It now says how the plugin decides where a handler goes, which is by folder and file name rather than by a decorator, and states the handler_binding and layers values of the capability's comparison, each on the README sentence it rests on. dependency_injection and draft_events are left unstated: the README mentions neither.TypeScript patterns
cds-plugin-typescriptprovides[typescript-patterns] revisedThe edge carried no sentence. It now says what the plugin does at build time and that it says nothing about the arrangement of the code it compiles. Whether the edge belongs on typescript-patterns is an open editorial question recorded with the capability's review: capire now ships a cds build task for TypeScript in @cap-js/cds-typer, which puts this plugin beside the core's toolchain answer rather than beside the arrangement options. No facet values are stated, because the capability's four facets ask about the arrangement and the README answers none of them.TypeScript patterns
cds-routing-handlersprovides[typescript-patterns] revisedThe edge carried no sentence. It now says what the package binds and where it stops, and states the handler_binding and layers values of the capability's comparison on the README sentences they rest on. No lifecycle field was added: the README read today carries no statement by its maintainer about the package's end, and the predecessor sentence in the one-liner is another author's reading, already attributed as such.TypeScript patterns
cds2typeslifecycle, provides[typescript-patterns] revisedThe edge carried no sentence. It now says what the tool produces and that it says nothing about the arrangement of the code around it. Whether this edge belongs on typescript-patterns at all is an open editorial question recorded with the capability's review: generating types from a model is the typing concern, and this pass does not move the edge.TypeScript patterns
com.sap.cds:cds-maven-pluginprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge said the goal rebuilds and restarts and left out that whether it restarts or reloads depends on Spring Boot Devtools, and that on Windows it does not work without them, which is the difference a reader on this flavor meets first.Generators
dev-approuterprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The capability now compares its options by the part of the local stack each one starts, and this package's own description states the part. Nothing was entered for the two flags: the registry page carries no README, so whether it resolves a cloud binding itself is not stated anywhere read here.Local development
Local developmentcore coverage, coverage by flavor, framing by flavor, facets revisedNine options answered this capability with nothing to compare them by, and they are not variants of one tool: the first question a reader has is which part of the local stack an option starts. The two flags separate the hybrid-testing helpers, where cds bind states that only the location of the credentials is stored on the machine and @sang2x/captools states that it writes the resolved VCAP_SERVICES into default-env.json.Local development

How to build reusable plugin components for CAP Java applicationspublishedA companion to Daniel SchlachterDaniel Schlachtercreated 9 pieces, contributed to 10 entriessap official's Reusable components for CAP with cds-pluginReusable components for CAP with cds-pluginThe post that taught the mechanism, and it teaches it by picking a requirement small enough to be absurd: every string a service returns should end in a random emoji. Working through that on the bookshop example leaves nothing to argue about except the plumbing, which is the point — what a cds-plugin is, where it hooks in, and why packaging it beats copying it into the next project. Vinícius Barrionuevo credits this post as the thing that gave him the idea for sap-cap-sdm-plugin, and it is hard to read the plugin ecosystem in this graph without it.published 2023-04-30, showing the same mechanism on CAP Java: a plugin ships as its own Maven artifact with an event handler and a
CdsRuntimeConfiguration implementation, registered through the JDK's ServiceLoader rather than any CAP-specific wiring. The walkthrough builds a cds-emoji-plugin-java jar that decorates @emoji-annotated fields on read, installs it to the local Maven repository, and adds it as a runtime dependency to a cds init --add java bookshop application. It argues the plugin mechanism was not new to CAP Java, just previously undocumented.Plugin authoringSAP Cloud Application Programming Model（CAP）：概要およびデモ - Part 1publishedIntroduces SAP Cloud Application Programming Model@sap/cdsThe CAP Node.js runtime, which compiles the CDS model, serves the services declared in it, answers generic requests before any handler runs, and loads every cds-plugin.sap official, cap as an open, opinionated framework that shoulders OData plumbing and database-specific code so a domain is modelled once in CDS, then builds a small bookshop project to show it: @sap/cds-dk@sap/cds-dkThe command line client and development toolkit for CAP projects, with the commands cds build, cds deploy, cds watch and cds add among them.sap official, cap's

SAP AI Services - DOX - Gen AI with SAP CAP Plugin - Part 3publishedBuilding on Reusable components for CAP with cds-pluginReusable components for CAP with cds-pluginThe post that taught the mechanism, and it teaches it by picking a requirement small enough to be absurd: every string a service returns should end in a random emoji. Working through that on the bookshop example leaves nothing to argue about except the plumbing, which is the point — what a cds-plugin is, where it hooks in, and why packaging it beats copying it into the next project. Vinícius Barrionuevo credits this post as the thing that gave him the idea for sap-cap-sdm-plugin, and it is hard to read the plugin ecosystem in this graph without it.published 2023-04-30 by Daniel SchlachterDaniel Schlachtercreated 9 pieces, contributed to 10 entriessap official, this part walks through a custom CAP plugin — a
cds-plugin.js plus a lib_cap_dox.js helper — that authenticates against SAP's Document Information Extraction (DOX) service and calls its schema and job-status APIs to fill an entity from extracted document fields. It covers reading the service key from Cloud Foundry (cf service-key) for the OAuth token endpoint, and dynamically mapping DOX's header and line-item output onto CAP entity properties.Plugin authoringTue 22

COMMIT WORK with the action approve_project written in EML in local mode, and rebuild the freestyle UI5 JavaScript app once in UI5 TypeScript and once as a Fiori elements list report and object page driven by metadata extensions. What the published transcripts add is how the agent got there: it found the generated MPC class names and the custom logic in DPC_EXT only by reading the system, the skills made it print the extracted model and stop for confirmation before writing, and @ui5/mcp-server, mcp-sap-docs and @sap-ux/fiori-mcp-server each had their own job beside it. The demo is small on purpose, and the post says a productive SEGW service that calls BAPIs, carries custom authorisation logic or supports deep inserts is not solved with one prompt.published 2026-05-11, from SAPUI5 1.84.59 to 1.147.2, the diff range held 985 deprecations and 961 What's New entries, and the lintingLintingCatching in the editor what would otherwise be caught at deploy time, or not at all — problems in source code and models and in the project's configuration, found by rules rather than by review.SAP and community, narrow by design and manifest validation narrowed that to findings in this app, among them jQuery.sap.require, synchronous bootstrap, the sap_belize theme, sap.m.MessagePage and an old manifest _version.

Documentationcoverage by flavor revisedThe only UI5-ecosystem artifact that states web-components in its flavors is ui5-webcomponents-mcp-server, sap-official, and no other UI5-ecosystem provider of this capability names the flavor at all — core-only per the reading rule. framing_by_flavor was left unset: framing_by_ecosystem.ui5 already describes this same artifact, and it already reads as the web-components flavor's own paragraph rather than a cross-flavor one, so a second copy would restate it rather than say something different.Documentation

How we could potentially have nestjs as runtime for SAP CAPpublishedA proof-of-concept that swaps @sap/cds@sap/cdsThe CAP Node.js runtime, which compiles the CDS model, serves the services declared in it, answers generic requests before any handler runs, and loads every cds-plugin.sap official, cap's ApplicationService and ODataAdapter dispatch for NestJS controllers, providers and interceptors, built by the author to learn NestJS rather than to ship a runtime. It works through CAP's run-dispatch-handle loop and AsyncLocalStorage-based transaction boundaries in detail before mapping them onto NestJS dependency injection and interceptors — one community answer to the controller-service-repository layering question core TypeScript support leaves open. The author's own conclusion is that the result reimplements CAP Java in Node.js, and they do not plan to take it further.TypeScript patterns

Add useful Extensions to Dev spaces in SAP Business Application StudiopublishedStarts from the point capire makes — that CAP is editor-agnostic and BAS is the preconfigured option — and then does the thing that undoes preconfiguration: adds two extensions to a dev space for initialising data in a CAP application, with the uninstall procedure as well as the install.

Avoiding Data Loss When Loading Initial Data with CSV Files in CAPpublished
cds add tiny-sample gives you a CSV in db/data and it loads on deploy, which looks like a way to seed a productive application.

Streamlining CAP Development with CDS Graphical Modeler in SAP Business Application StudiopublishedThe case for the graphical modeller stated as a scale problem rather than a preference: a model held only as code gets hard to keep in your head once it is large, and the diagram is a second view of the same file. The most recent write-up of the tool here, and the one that treats it as an everyday working aid rather than as a new feature.Editor support
Taking CAP to the next level - with TypeScriptpublishedThe author's own two packages introduced together, and they are two halves of one idea: cds2typescds2typesA command-line tool that generates TypeScript interfaces from a CDS model, written before @cap-js/cds-typer existed.independent, cap generates TypeScript from the CDS model, cds-routing-handlerscds-routing-handlersDecorator-based routing of CAP service handlers in TypeScript, from before the core had an opinion — the framework the CDS-TS-Dispatcher post names as its unmaintained predecessor.independent, cap arranges the handlers that use them. Published in 2020, years before cds-typer, which makes it the earliest answer in the graph to a question the core answered later.TypeScript patterns
Testing your CAP HANA Artifacts with jest – including multitenancy, hdbprocedure and hdbviewpublished
cds.test covers the service; this covers what is underneath it, where the artifact is an hdbprocedure or an hdbview that CDS never sees. That means a real HDI container, so most of the post is about where to get one and how to give CAP access to it — the tests are the easy part once that is true.TestingThe CAPstone Project: A Journey from Component to CloudpublishedA React and Vite front end on a CAP backend, written for two readers at once — the React developer curious about SAP, and the CAP developer wondering about modern front ends. Predates CAP's own React and Vue support.Reference apps
Tips and Tricks for Working with Annotations in CAP Projects using Language Server Protocol (LSP) capabilitiespublishedFour settings, from somebody who works on the annotation language server. The premise is the interesting part: CAP's annotation syntax is looser than ABAP CDSABAP CDSThe modelling layer of ABAP Cloud — view entities, projections and annotations defined above database tables, delivered with the platform rather than installed.sap official, abap or EDMX — a record can be written with or without an explicit type — so the completion has to guess how verbose you want it, and this is where you tell it. Then filtering the completion list, reading the icons, ordering diagnostics by severity, and turning i18n problems on only when you want them.Editor support
TypeScript Sheriff: How can I use TypeScript in the SAP ecosystem? (Part 2 of 3)publishedThe middle part of three, and the one about SAP: where TypeScript is supported across a side-by-side extension on BTP, as of July 2023. It says the SAP Cloud SDK already generates OData clients as .ts files and UI5 ships types for its controls and modules, the ground of TypeScript supportTypeScript supportWriting apps and libraries in TypeScript — the type definitions, the module syntax the loader expects, and the build step that gets from one to the other.SAP and community, narrow by design in UI5, while CAP offers standard types and the new @cap-js/cds-typer@cap-js/cds-typerGenerates TypeScript types from a CDS model.sap official, cap generates types for a service, which is typingTypingMaking the model visible to the compiler — generated types for entities and events so a rename breaks the build rather than production.SAP and community, unassessed, with the caveat that running cds-ts commands could overwrite what cds-typer generated.Typing
UI5ers Buzz #56: New full-stack UI5 sample app featuring CAP + OData V4 + draft modepublishedA sample app published as code rather than described — SAPUI5 over a CAP service with OData V4 and draft mode — and the note that it was built on what the team learned from an application written in March 2020 to help the German Foreign Office repatriate citizens. That provenance is unusual and worth keeping.Reference apps
Use Tasks in Visual Studio Code to start a cds service, an approuter and launch a browser in one gopublished
cds watch serves the service and the app folder but not the approuter, so anything needing a JWT means a second terminal started by hand. This replaces that with a VS Code task definition — the tasks.json is in the post — so the whole local stack comes up on one command.Local developmentUse TypeScript with the SAP Cloud Application Programming ModelpublishedWritten 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.TypeScript patterns

A Fiori Launchpad Sandbox for all your CAP-based projects - OverviewpublishedWhere cds-launchpad-plugincds-launchpad-pluginIndexes every SAPUI5 application in a workspace into one sandbox launchpad served by the CDS server, so all of them can be opened from a single page while developing.independent, cap came from, told as a learning exercise: the author wanted a real problem to teach himself TypeScript on, and picked the thing he kept redoing in every CAP project — a launchpad to see all the UI applications in one place. The origin post for an entry whose 2023 update is also indexed here.Testing
A Fiori Launchpad Sandbox for all your CAP-based projects – Sample project setuppublishedThe hands-on half published the same day as the overview: the launchpad module wired into the CAP sample repository, step by step from a global cds-dk install.

Avoid design time CAP server restarts when maintaining local data filespublishedcds watch restarting on every file change is the feature; this is the case where it is not.

A small friction most people work around silently rather than fix.Local development

cds-launchpad-plugin supercharged & ready for the future - CAP Plugin, UI5 Tooling support & Async LaunchpadpublishedThe maintainer on a set of changes rather than on the plugin's original purpose, which is indexing every SAPUI5 project in a workspace into one sandbox launchpad so all of them can be tested together. What moved: it became a CAP plugin, gained UI5 Tooling support, and moved to the async launchpad — each framed as keeping pace with where SAPUI5 itself is going rather than as a feature.Testing
CDS-TS-Dispatcher: Simplifying SAP CAP TypeScript DevelopmentpublishedThe 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.TypeScript patterns
CDS-TS-Repository: Simplify SAP CAP Entity persistance with BaseRepositorypublishedThe 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.TypeScript patterns
debug a CAP app with UI5 TypeScript UI component with VS CodepublishedDebugging both runtimes at once — the CAP server and a UI5 component written in TypeScript, the latter stepped through in its own sources rather than in the transpiled output. Written when TypeScript for UI5 had just become possible, and the combination it sets up is the one CAP's app folder invites.Debugging
Develop CAP Project with Lazyvim in DockerpublishedA Docker image running Lazyvim with language server support for CDS, TypeScript and JSON, so a CAP project can be developed with an editing experience comparable to VS Code without leaving the keyboard.

Develop SAP CAP apps inside a VS Code Docker ContainerpublishedA VS Code dev container configuration with everything a CAP project needs already in it, published as a repository rather than as instructions.

A setup walkthrough rather than an argument about typing, and it stops at the point where the application works on a laptop; deployment is part two.Typing
Exploring the TypeScript Ecosystem with @cap-js/cds-typer, cds-ts, and node-ts Part - 2publishedPart two takes the TypeScript project from part one to Cloud Foundry: cds add mta, then the parts of the generated descriptor the author singles out as needing attention for a TypeScript build rather than a JavaScript one. The pair together is the whole path — typed model locally, then deployed — which is where a typing walkthrough usually stops short.Typing

Introducing eslint-plugin-better-cap-config an ESLint plugin to improve CAP configurationpublishedThe author's own announcement, and precise about scope: today it catches deprecated key/value entries in CAP's JSON configuration, and the ambition is that it grows into best practices, suggestions and autofixes the way any ESLint plugin does. The implementation detail worth knowing is that it uses modern ESLint's JSON language support rather than a generic parser, which is what makes linting a configuration file rather than source code work at all.Linting
ISO content for common CAP typespublishedThe npm package that supplies ISO-standard content — countries, languages, currencies, timezones — for CAP's common types, and how it works underneath.

SAP CAP: Controller - Service - Repository architecturepublishedThe 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.
