HTML_WITH_UPPERCASE_SVG_ONLY so its test verifies uppercase .SVG suffix handling
independently of MIME filtering; leave the test and other fixtures unchanged.

For the last question, I don't think it is out of scope. |
Cover the common favicon cases described in the issue: case-insensitive `.svg` suffixes, `type="image/svg+xml"`, `sizes="any"`, and multiple `rel` tokens. Reset fetch-mock in an `afterEach` hook so the cleanup runs even when a test fails, keeping each test isolated from the others. Assisted-by: Claude Code:claude-opus-4-8
- Adds the `g` flag so every declared size is matched, not just the first. - Rewrites the size check to keep the icon when any single size is large enough. Assisted-by: Claude Code:claude-opus-4-8

- Line 185: Update the multi-size icon candidate in the test for getFaviconUrl
to use a URL distinct from the `/favicon.ico` fallback, and assert that the
result uses the corresponding absolute candidate URL so the test verifies
multi-size icon selection.

Looks good to me. The NodeInfo tests pass on Deno, Node.js, and Bun.
One small suggestion: remove type="image/svg+xml" from the uppercase .SVG fixtures, including the query/hash case, so those tests catch regressions in the URL suffix check independently of MIME filtering. This doesn't block approval.

Summary
Improve favicon selection by adding tests and detecting SVG favicons via the
typeattribute ingetFaviconUrl()(packages/cli/src/nodeinfo.ts).Related issue
fedify nodeinfo#893Changes
getFaviconUrl()covering multiplereltokens, SVG skipping (.svgsuffix, uppercase, query/hash, andtype="image/svg+xml"),sizes="any", and bitmap preference.mise run test:deno packages/cli/src/nodeinfo.test.ts, I noticed that when an earlier test fails, its trailingfetchMock.hardReset()never runs and leaks mock state into later tests. I added anafterEach()hook so each test stays isolated regardless of failures.getFaviconUrl()that detects SVG favicons declared via thetype="image/svg+xml"attribute.AI disclosure
Claude Code (
claude-opus-4-8) was used as an advisor: it reviewed my code and helped investigate behavior.Notes
getFaviconUrl()logic, when an icon declares multiple sizes (e.g., hackers.pub's16x16 32x32 … 256x256), only the first size is checked; if that one is too small, the icon is discarded even though a larger256x256is available, and the selector falls back to the next candidate (the apple-touch-icon, 180px).I'd like to fix this so it considers all declared sizes and does not skip the
256x256. Would this fix fit the scope of the current issue, or should I open a new issue for it?
