feat: replace FontAwesome with Lucide icons - #589
Conversation
📝 WalkthroughWalkthroughThe application replaces Font Awesome with Lucide across dependencies, map markers, Svelte components, providers, error views, trip planning, and tests. Route marker SVG generation now serializes Lucide icon nodes. Search and trip-planning mounting behavior also changed. ChangesLucide icon migration
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to This change replaces FontAwesome icons across maps and trip-planning views, but some transport modes may be visually indistinguishable, directional arrows may render incorrectly in right-to-left layouts, and survey state may persist across survey changes for the same stop. The PR is mergeable with explicit owner awareness and follow-up on these localized UI correctness issues. Possibly related PRs

This is a genuinely well-executed migration, and a big one — 43 files, every FontAwesome call site converted, the @fortawesome/* packages and the unused flowbite-svelte-icons all dropped, and the CLAUDE.md styling line updated to match. A few things I checked specifically that held up:
generateRouteTypeSvgForDisplayserializing Lucide'sIconNodearrays into inline SVG is the right approach for the map vehicle markers, andstroke="inherit"resolves correctly against the parent<g stroke="${color}">ingenerateVehicleIcon.js.- Dropping FontAwesome's implicit
aria-hidden/focusable="false"is safe —@lucide/sveltesetsaria-hidden="true"by default. No accessibility attributes were removed anywhere in the diff, and two were added. - The
routeTypeIconslookup-table rewrite preserves the oldswitchsemantics including theUNKNOWN: 999default. - Extending
rotate-rtlto directional icons that never had it is scope creep, but it's correct scope creep — those arrows and chevrons should all mirror.
First, a correction to my earlier comment
My automated review comment on this PR overstated the caret problem. It said the carets sit "~5-8px away from the marker box instead of touching it" and that the new triangle is "about 40% of the old height." Both numbers are wrong, and the second compares the new triangle against the old element box rather than the old triangle. I worked the geometry out properly afterward. Sorry for the noise — here are the real numbers.
The direction carets did shift, but modestly
faCaretUp's viewBox is 320x512, and the drawn triangle occupies y=137.4 to y=320 of it — so at font-size: 20px with FA's height: 1em, the element box was 12.5x20px and the visible triangle inside it was 12.5x7.1px, sitting flush with the box's bottom-ish area with ~7.5px of empty space below it.
The replacement is a fixed 12x12 box whose polygon covers 20/24 x 16/24 of the viewBox, so the visible triangle is 10x8px with 2px of space below it.
Net effect against the unchanged .direction-arrow.{n,ne,...} offsets:
wayfinder/src/components/map/StopMarker.svelte
Lines 96 to 107 in 77b68b1
- The caret sits about 2.5px further from the marker than before (for
n, the gap goes from 7.5px to 10px). Worth knowing: the old caret never touched the marker either — that 7.5px gap was the design. - It's about 20% narrower (12.5px to 10px).
- The
e/wvariants barely move, since the rotation is about the box center and both boxes are near-square after rotating.
So it's a subtle drift rather than a detached-caret bug, and I'd have called it fit-and-finish if the fix weren't a one-liner. Giving the caret width: 12.5px; height: 20px (or width: 0.625em; height: 1em, which keeps it tied to the existing font-size: 20px) restores the old box and makes the eight offsets correct again without touching them.
Related and worth folding in while you're there: .bus-icon { font-size: 20px -> 24px } on line 216 is now inert. Nothing in that span reads font-size anymore — the route icon is sized by h-6 w-6 and the caret by its width/height attributes. Either drop the declaration or size the caret from it.
Two smaller things, take or leave
faClockRotateLeft became two different Lucide icons for the same concept: History on the Recents toggle in TripPlan.svelte, RotateCcwClock in RecentTripsList.svelte. Those render adjacent — the button and the list it opens — so I'd pick one.
RAIL/TRAIN and TRAM both resolve to TramFront now, where FA distinguished them. Your mapping table calls this out as deliberate, so I'll defer to you, but Lucide's TrainFront is the closer analog for rail if you want the distinction back.
Fix the caret sizing and I'll merge this. Nice piece of work — the mechanical parts of a 43-file swap are exactly where mistakes hide, and I didn't find any.
Address review feedback on the FontAwesome -> Lucide migration: - StopMarker: size the direction caret svg to 12.5x20 (the old faCaretUp element box at font-size 20px) so the eight positional offsets stay correct without retuning them - StopMarker: drop the now-inert .bus-icon font-size (route icon is sized by h-6 w-6, caret by its own width/height) - RecentTripsList: use History for the recents icon to match the Recents toggle in TripPlan (was RotateCcwClock), so the button and the list it opens share one icon for the same concept

The caret fix is right, and thanks for taking the two "take or leave" notes as well — 12.5 x 20 restores the old FA element box exactly, so the eight positional offsets keep working without retuning, the now-inert .bus-icon { font-size } is gone, and RecentTripsList matches TripPlan on History. The mechanical parts of a 43-file swap look careful: no aria-* attributes were dropped anywhere in the diff, no FontAwesome references linger in src/, and lint/build/tests are all green locally on cb67aa4.
There's one thing I need fixed before this can land, and it's not something the screenshots or CI would show you.
Every Lucide icon silently drops the first class you pass it
@lucide/svelte@1.30.0's Icon.svelte sets its class with the array form:
class={['lucide-icon lucide', globalProps.class, name && `lucide-${name}`, props.class]}Array/object class values landed in Svelte 5.16.0. package-lock.json on this branch pins svelte 5.2.8, where that array just gets stringified — commas and all. I rendered a real Lucide icon in this branch's own environment:
class="lucide-icon lucide,,lucide-bus-front,absolute -right-1 -top-1 h-6 w-6"
classList: ["lucide-icon", "lucide,,lucide-bus-front,absolute", "-right-1", "-top-1", "h-6", "w-6"]
The first class you pass gets fused into a junk token and is lost. Everything after it survives — which is exactly why this is easy to miss: most of your h-N w-N pairs still look fine because the surviving w-N plus the viewBox letterboxes the glyph back to roughly the right size.
Where it actually breaks:
TripDetailsPane.svelte:176—class="absolute -right-1 -top-1 rounded-full …"on the<Check>badge.absoluteis dropped, so the check lays out in flow instead of pinning to the corner of the bus marker.- RTL mirroring, everywhere —
rotate-rtlis the first class on nine icons (CollapsedSearchField,StopPageHeader,ServiceAlertsx2,ServiceAlertItem,LegDetailsx4,+error). None of them will ever mirror.CollapsedSearchFieldis a regression, not just a missed conversion: ondevelopit's<FontAwesomeIcon class="rotate-rtl …" />, and FA passesclassthrough as a plain string, so RTL works there today. TripPlanSearchField.svelte:55—size-5dropped; the clearXfalls back to Lucide's default 24px.TripPlanSearchField.svelte:74—mr-2dropped; no gap between the pin and the result text.+error.svelte:72—h-10dropped whilew-10survives, so the box is 40x24.
The fix
Bump the locked Svelte to 5.16.0 or newer. I tried it on your branch:
npm install svelte@5.16.0
- the class attribute comes out clean:
"lucide-icon lucide lucide-arrow-right rotate-rtl h-3.5 w-3.5 text-black" rotate-rtl/absolute/size-5all survive- full suite still green: 101 files, 1776 tests
Worth noting I also tried the latest (5.56.9) and one TripPlanModal test fails there, so 5.16.0 is the clean minimum — I'd go with that rather than latest in this PR, and leave a larger Svelte upgrade for its own change.
Not blocking, up to you
- Caret geometry, ~1.7px. The new
viewBoxis square (24x24) where faCaretUp's was 320x512, sopreserveAspectRatioletterboxes the triangle to 12.5x12.5 inside the 20px box. Net: the caret base sits 5.83px above the marker vs. the old 7.5px — it now slightly overshoots where it used to undershoot. Smaller than what I flagged last time, so I'm happy to call it done;viewBox="0 0 24 38.4"would make it exact if it bugs you. RAILandRAIL-adjacent both map toTramFront(routeConfig.js:38), so rail and tram render identically where FA distinguished them.TrainFrontis the closer analog. Your call — I raised this before and I'm still fine either way.
Ordering with #585
Your other open PR adds src/components/favorites/*, and those files import @fortawesome/* — which this PR deletes from package.json. Whichever lands second will fail to build, not merely conflict. #585 has one outstanding change request from me too, so the simplest path is: fix that one, I merge it, then you rebase this and convert the three favorites files to Lucide here. If you'd rather land this one first, tell me and I'll flip the order.
Ping me when the Svelte bump is in and I'll get straight back to this — the rest of the migration is in good shape.
Lucide's Icon.svelte passes class as an array; array/object class support landed in Svelte 5.16.0. The branch pinned 5.2.8, which stringified the array and fused/dropped the first class (absolute, rotate-rtl, size-5, mr-2, h-10). Bumping the locked svelte fixes all of these at once. Full suite green: 101 files, 1776 tests.
