Every keystroke the filter rebuilt the lowercased + diacritic-stripped + soft-hyphen-stripped concat of name/description/tags per recipe. For a 200+ recipe catalogue that's a lot of regex work on the hot path. Cache the normalised string in a WeakMap keyed by the recipe object; first keystroke still pays the full cost, every subsequent one is a single indexOf per recipe. Picked client-side memoisation over the audit's suggested server-side `_searchKey` to avoid duplicating every recipe's text over the wire.

Perf (audit 2026-04-23)
Order = impact. Font items + app.html preload intentionally skipped.
- 1. Lucide subpath imports — convert
from '@lucide/svelte'barrel imports to@lucide/svelte/icons/<kebab-name>so Vite tree-shakes per-icon (current 748 KB shared chunk) - 2. Chart.js dynamic import in
FitnessChart.svelte(drop 244 KB from non-stats fitness routes) - 3. Recipe API endpoints — drop
JSON.parse(JSON.stringify(...))double-serialize (9 endpoints). Client-side shuffle / cache headers deferred (would require rethinking hero preload + hydration) - 4. Favorites page — drop unnecessary
all_brieffetch (verified Search usesfavoritesOnlysoallRecipeswas redundant) - 5. Replace redundant
locals.auth()withlocals.sessionacross all routes (68 files, 107 sites — loaders, actions, API endpoints) - 6. Stream fitness stats loader — muscleHeatmap, nutritionStats, periods, sharedPeriods now stream via
{#await}.statsstill awaited (too many chart $deriveds depend on it) - 7. Muscle-heatmap endpoint — add projection + O(1) bucket math. Overview already had a projection; set-subfield narrowing was attempted but reverted (returned malformed sets). Timeseries cap not feasible: totals are lifetime-scoped.
- 8. Calendar payload trim —
yearDaysnarrowed to{iso, color}(needle lookup only), new pre-filteredfeastDotsarray carries feast-specific metadata. Also fixed a stray doublelocals.session ?? (locals.session ?? …)in both calendar page loaders. - 9. History sessions endpoint — projection narrowed to exactly what SessionCard reads (drops notes, templates, mode, endTime, session-level gpsPreview); added
.lean(). - 10.
Cache-Controlheaders: 8 h public on the shuffled recipe list endpoints (all_brief,category/[c],tag/[t],icon/[i],in_season/[m]) — rand_array is seeded per UTC day, safe to share. 1 h public on distinct-value lists (category,tag,icon). 5 min public on recipe detail.private 1hon fitness/exercises/filters. Calendar page skipped (session serialised into layout HTML). - 11. Search — debounce was already 100 ms. Instead of a server-side
_searchKey(would duplicate text over the wire), memoise per-recipe normalized string in aWeakMapon the client — built lazily, reused across every subsequent keystroke.
Features
[x] on /fitness/measure, fill "Past measurements" in SSR only for the last 10 measurements. anything further should be fetched client side on mount to decreae initial page load time. use a "show more" button and paginate measurments. [x] on /fitness/measure (resp. their associated logging API routes), consolidate measurements by day. If we want to log another measurement, overwriting an old one, show a warning to indicate this. disparate measurements (e.g., weight and bodyfat) should not show this warning but simply be merged into one log entry for that day. [x] on /fitness/measure in the past measurments tab, show more than "Body measurements only" if we don't have Bodyweight logged. we can be a bit more elaborate in our syntax here tbh. [x] add a button on /fitness/measure/body-parts for each measurement directly below to say "Same value", instead of having to hit +, then - to lock in same number [x] BF graph (with trend line like weight graph) on /fitness/stats page. Emphasize relative changes, not absolute numbers in design (as we cannot trust those) (e.g., use start day of overview as 0% and then show +/- x % on the graph) [x] Workshop better names than "Measure" for the /fitness/measure route. It's about body data points (i.e., non-food related). What's a better, short name than "Measure" to capture the logging of weight, body composition, body part measurements, and period tracking? [x] on /fitness/stats/histoy/ for body measurement graphs, make the range reasonable. e.g., if we have 1 cm change, do not fill the entire y-height with 1 cm. Use reasonable padding for low ranges (i think we do something like htis already on the weight graph?) [ ] on /fitness/check-in, Make the Period ended button a lot more prominent in the period tracker component. [ ] swap heart emoji on recipe favorites to lucide icon [ ] coop and migros cards on shopping list for scanning [ ] login icon from lucide in header
Refactor Recipe Search Component
Refactor src/lib/components/Search.svelte to use the new SearchInput.svelte component for the visual input part. This will:
- Reduce code duplication between recipe search and prayer search
- Keep the visual styling consistent across the site
- Separate concerns: SearchInput handles the UI, Search.svelte handles recipe-specific filtering logic
Files involved:
src/lib/components/Search.svelte- refactor to use SearchInputsrc/lib/components/SearchInput.svelte- the reusable input component
