Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe change adds pipe discovery through a new RPC, a Pipes inspector tab and dashboard card, and a Pipes example page. The example uses pure, impure, and NgModule-declared pipes. The app also updates shared tab types and the extension UI bundle reference. ChangesPipe discovery and examples

- Around line 217-233: Add a catch block in PipesInspector.refresh() to handle
rejected get-pipes RPC calls and prevent unhandled rejections when refresh() is
invoked without awaiting it. Keep the existing finally block so loading is reset
after either success or failure.
- Around line 193-209: Update the file-path comparison in the filtered signal’s
effect so it lowercases p.file before checking whether it includes the
lowercased query q; leave the other filter comparisons unchanged.
In `@src/app/examples/pipes/truncate.pipe.ts`:
- Line 7: Update the truncation logic in the pipe’s transform method so results
including the ellipsis never exceed limit; when truncation is needed, reserve
one character of the limit for the ellipsis, including for small limits.

Lowercase the file path before filtering.
filter() is lowercased, but p.file is compared unchanged. A scanned path with uppercase characters can fail to match a lowercase query.

+ p.file.toLowerCase().includes(q),📝 Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Handle get-pipes failures in refresh().
refresh() has try/finally but no catch. The effect at Line 211-214 and the Refresh button call refresh() without awaiting it. If the RPC call rejects, the rejection is unhandled. The UI then shows "No pipes found." with no error indication. The other inspectors catch RPC failures (see di-inspector.ts loadSourceProviders). Add a catch block and optionally show an error state.

Keep the ellipsis within limit.
The aria label promises truncation to 24 characters. The current pipe keeps 24 source characters and then appends …, so the displayed result can contain 25 characters. Reserve one character for the ellipsis, including when limit is small.

Nice one, works well locally. Format, typecheck, tests and build all pass.
One thing will fail CI once it runs: the committed extension/ui is stale. A fresh build gives index-DSjzy8zx.js, the PR has index-DgmJxXkW.js. Run pnpm extension:build && pnpm devtools:build-pkg and commit the result.
Also worth fixing CodeRabbit's 3 small comments, especially the missing error handling for get-pipes in refresh().
|
Idea for a follow-up: add runtime data from the running app, since the source scan only shows what exists, not what runs.
All of this relies on internal Angular details and only works in dev mode, so it needs feature detection and a quiet fallback. |
