Everything in the atlas

Event roundtrips and visual fidelity stay with a live run: the documentation leaves those to the project's MCP server and to [abap2UI5 for VS Code](artifact:abap2ui5-vscode-extension). A class that builds view parts in helper methods without the handle idiom cannot be statically reconstructed, and the render gate is then skipped with a notice while the property gate runs on what was reconstructed. A screenshot is not a preview of the app: nothing round-trips, no event reaches ABAP, and a table filled by a SELECT photographs empty unless a mock JSON file sits beside the source.

Every gate here runs off-system, so what the class does on a real system and what the view does on the oldest UI5 release it has to serve are what the `pitfalls` catalogues carry and no local run can see. It runs abap2UI5 app classes, so ABAP that is not one has nothing here to deploy into. In system mode the sandbox tools are not offered, and an `app_act` event runs on the system as the configured user.

What adt-ls cannot do headless the maintainer puts out of scope, so a consumer that needs an ADT call the language server does not expose is back to speaking ADT itself. The README states the current runtime compatibility as verified on macOS arm64, against adt-ls 1.1.2 as the minimum and `1.1.2.202608131517` as the version tested. An Eclipse installation does not supply that runtime: SAP versions the two separately, so the VS Code extension has to be installed even where nobody opens VS Code.

It is a bundle, not a plugin with one job. Depending on it for one feature brings the rest.

If you need sub-second fan-out to external consumers this is the wrong layer — reach for [Event Mesh](artifact:btp-event-mesh) or Kafka. Without [Redis](external:redis), periodic processing still works but instant dispatch degrades to polling.

If document versions are required, [@cap-js/sdm](artifact:cap-js-sdm) excludes versioned repositories in its [documented restrictions](https://raw.githubusercontent.com/cap-js/sdm/ad13b61f21816ebead2d08264a74521cfb75846c/README.md).

The manifest calls it a dummy library exposing custom CDS annotations, but the published contents are a one-line README, a single exported barrier() whose body is throw Error("not yet implemented"), and no .cds file at all — there is nothing to import and nothing to annotate with. No repository, one release, May 2025.

Neither the package manifest nor the repository tree declares a licence.

The metadata is inconsistent: the declared repository is github.com/acme/search-vocab and the README installs @acme/search-vocab, neither of which matches the published name. One release, November 2025.

It writes and it administers — ETL extraction and database user management are not read operations, and the same connection that profiles a column can move data out of the tenant. Masking is only as good as the configuration naming the fields, so an unlisted sensitive column is an unmasked one.

The README is one line and the package carries no licence field. Last released July 2023. The repository the package declares has been deleted — verified against the GitHub API, not just a failed fetch. The package is still on npm, so it installs; the source it was published from is no longer readable, which is a harder thing to discover than a stale version number.

Release and repository quiet for 39 months.

Tied to a specific training repository and last released August 2023. The repository the package declares has been deleted — verified against the GitHub API, not just a failed fetch. The package is still on npm, so it installs; the source it was published from is no longer readable, which is a harder thing to discover than a stale version number.

There is no repository and no README: what the eight commands do is only readable from the compiled dist that ships in the package. Three of them — npmrc, install, project — are written for "SimpleMDG" projects rather than for CAP generally, so the reusable part is bind-local, run-local and debug. Seven releases up to July 2026. Its binding step writes the resolved VCAP_SERVICES into default-env.json in the project, where [@sap/cds-dk](artifact:sap-cds-dk) keeps only the place the credentials can be fetched from, so a project using it needs that file kept out of version control.

There is nothing to run: it is published for a generator or a script to call, not for a developer to invoke in a project, and it declares Node.js 22 or later.

Its own account of itself is local running and tests: the DCN it writes serves as input for running an application using AMS on the DCL bundle locally. It carries the SAP Developer License Agreement rather than an open-source licence, and the repository named in its package metadata is an internal SAP host, so the npm page is the only thing to read.

A library a VS Code extension calls, not something installed and run on its own; there is no documented standalone CLI. No public repository either, so what it does is read from its own README rather than checked against source.

Specific to MDK metadata projects — nothing here builds or deploys a CAP service or a plain Fiori app. Closed-source, under SAP's own developer licence rather than a public repository.

Not in a project whose dependencies must all carry an open-source licence: KAEV is proprietary software, its licence page states that downloading or viewing the npm package does not by itself grant permission to use, copy, modify, redistribute, sublicense, sell, host or create derivative works, and the LICENSE file shipped with the package carries the controlling terms. Not as the last word on whether a UI5 application is secure: its rule reference states that a heuristic finding is not proof of a vulnerability, and its documentation puts professional security review beside it rather than under it.

Lowercase HTML tags such as `<div>` typecheck but throw: the default renderer constructs UI5 controls, and the HTML-aware renderer plugin is described as planned. `withScope` restores the previous scope on a synchronous return only, so an `await` inside its callback leaks the scope on runtimes without `AsyncLocalStorage`. A view that has to stay adaptable through UI5 flexibility has no path here yet: the project's [Devtoberfest session](content:devtoberfest-2026-ui5-views-type-safe-tsx) states that flexibility support is not built in yet.

It shows the wiring and a converted view pair, not the runtime's API surface; the directives, the plugin SPI and the binding forms are demonstrated in [@ui5-community/jsx-runtime-showcase](artifact:ui5-community-jsx-runtime-showcase) instead.

Its views are not a template for application code: every showcase view overrides `getController()` to return itself so a sample stays readable in one file, and the gotchas page says not to ship that in production, where a view keeps a separate `*.controller.ts`. Routing from a sample, an `ODataModel` v2 or v4, `sap.ui.mdc.Table`, forms and custom control authoring in TSX are absent by decision and documented as deferred.

It reads a UI5 project and the framework's own documentation, not a running system or a backend: a question about the service behind the app is answered somewhere else. Node.js v20.17 or v22.9 and above.

The declared repository is archived.

Not where the UI library itself is expected to bind data: the documentation leaves binding a component's content and events to the host framework. Not from a CDN script tag: the project publishes none, so it assumes a build step.

Quiet No published releases; repository quiet for 41 months.

Functional boundary Not in a production environment yet: the maintainer puts abaK in beta, says its API can still change and more tests are needed, and asks that a non-beta release be waited for.

Nothing to choose here and nothing to install: it is what an ABAP Cloud system gives you. It shares a name and a lineage with CAP's CDS but is a different language in a different runtime, and a model does not move between them.

On a system below ABAP 7.51, or one without a connected HANA database, the client-based mode does not run, and the server-based mode is only available where the abap-code-search-tools backend is installed in the system.

It is an Eclipse install. A development object that is not native-integrated in Eclipse opens in the SAP GUI that is installed locally with the client.

On a system where the abap-search-tools backend is not installed: the plugin lists it as a precondition, and the beta update site expects that backend's dev branch in particular.

In beta by its own page's account, where conversion bugs may occur and not all functions and variants are supported yet. The shapes named as not yet supported are sub selects, FOR ALL ENTRIES, functions such as count and sum, and the IN operator with a value list, so a statement built on one of those is outside what the converter sets out to do.

Quiet No published releases; repository quiet for 27 months.

Functional boundary It binds to the .abap and .ABAP file extensions inside Visual Studio Code, so it does nothing for ABAP opened in another editor, or for source read from a system over ADT instead of from a file on disk.

No published releases; repository quiet for 28 months.
