Summary

Adds full-text and semantic search to the pal-e-app frontend, backed by the pal-e-docs /notes/search API endpoint. Users can search across all notes using keyword, semantic, or hybrid mode, with results showing title, note_type badge, project, headline snippet, and rank score.

Changes

  • src/lib/api.ts: Added SearchResult interface and searchNotes() function calling GET /notes/search with query params (q, mode, alpha, note_type, project, limit)
  • src/routes/search/+page.server.ts: New server load function that reads URL search params and calls searchNotes(), returning results + query state
  • src/routes/search/+page.svelte: Full search page with input, mode toggle (keyword/semantic/hybrid), filter pills, results list with type badges and headline snippets, empty state with search tips
  • src/routes/+layout.svelte: Added nav bar search input (right side) with keyboard shortcuts (/ and Cmd+K to focus), submits to /search?q=...
  • src/routes/projects/[slug]/+page.svelte: Fixed pre-existing build error: inlined COLUMNS constant instead of importing from $lib/api (which pulled in $env/dynamic/private into client-side code)

Test Plan

  • Navigate to /search -- should show empty state with search tips
  • Enter a query and submit -- results appear with title, type badge, project, headline snippet
  • Toggle between keyword/semantic/hybrid modes -- results change
  • Click a result -- navigates to /notes/{slug}
  • Press / from any page (not in an input) -- nav search focuses
  • Press Cmd+K from any page -- nav search focuses
  • Enter a query in nav search and press Enter -- navigates to /search?q=...
  • Reload the search page -- query params persist
  • npm run build passes

Self-Review

Build: npm run build passes. npm run check passes with 0 errors (1 a11y warning for intentional autofocus on search page).

Files changed (5):

File Change
src/lib/api.ts Added SearchResult type + searchNotes() function
src/routes/search/+page.server.ts New server load -- reads URL params, calls searchNotes()
src/routes/search/+page.svelte Full search UI with mode toggle, results, empty state
src/routes/+layout.svelte Nav search input + / and Cmd+K keyboard shortcuts
src/routes/projects/[slug]/+page.svelte Fixed pre-existing build error (inlined COLUMNS constant)

Findings:

  • No issues found in search implementation. API client, server load, search UI, headline sanitization, and keyboard shortcuts all follow existing codebase patterns.
  • Pre-existing note: projects/[slug]/+page.svelte references data.board which the server load does not return. This is a pre-existing type error (not introduced by this PR) and is guarded by {#if board} so it renders gracefully. Tracked separately.
  • navSearchMode in layout is not user-configurable from the nav bar (defaults to hybrid). This is intentional -- the full mode toggle lives on /search page. Nav search is a quick shortcut.

Verdict: Ready for merge.

PR #16 Review

BLOCKERS

1. Missing loading indicator (AC5)
Acceptance criterion #5 requires: "Loading indicator during semantic search." There is no loading state in the code -- no $state variable tracking request progress, no spinner, no "Searching..." text. Semantic search can be noticeably slow (embedding generation + vector similarity), so this is a real UX gap, not just a cosmetic miss. The +page.svelte needs a loading state that activates between doSearch() navigation and result render.

2. Mode toggle does not auto-update results (AC4)
src/routes/search/+page.svelte lines 81-91 (in diff): The mode toggle buttons only set mode = m in local state. They do not call doSearch(). AC4 says "Mode toggle updates results and persists in URL" -- currently, toggling mode does nothing visible until the user manually clicks Search again. Either doSearch() should be called on mode change (when a query exists), or this acceptance criterion needs to be revisited.

NITS

1. Unchecked mode cast -- src/routes/search/+page.server.ts:7

const mode = (url.searchParams.get('mode') as 'keyword' | 'semantic' | 'hybrid') || 'hybrid';

This casts any arbitrary string to the union type without validation. A URL like ?q=test&mode=evil would pass evil through to the backend. The backend likely validates, so this is not a security issue, but a defensive check (e.g., falling back to hybrid for unrecognized values) would be cleaner:

const raw = url.searchParams.get('mode');
const mode = ['keyword', 'semantic', 'hybrid'].includes(raw ?? '') ? raw as '...' : 'hybrid';

2. Unused navSearchMode variable -- src/routes/+layout.svelte:12
navSearchMode is declared and used in handleNavSearch() to set the URL mode param, but there is no UI element in the nav bar that lets users change it. It will always be 'hybrid', making the conditional if (navSearchMode !== 'hybrid') dead code. Either add a mode selector to the nav or remove this variable and the conditional.

3. COLUMNS / COLUMN_COLORS duplication
These constants now exist in three places: src/lib/api.ts, src/routes/projects/[slug]/+page.svelte, and src/routes/boards/[slug]/+page.svelte. The PR description explains why the inline was necessary (avoiding $env/dynamic/private in client code), which is valid. But these should be extracted to a shared client-safe module (e.g., $lib/constants.ts) to avoid triple-maintenance. Not blocking, but a cleanup target.

4. COLUMNS still exported from api.ts
After inlining COLUMNS in the project page, nothing imports COLUMNS from $lib/api anymore (confirmed by grep). The export is now dead code. Low priority but should be cleaned up.

PR #16 Re-Review

Re-review after blocker fixes from first QA pass.

BLOCKER FIXES VERIFIED

1. Loading indicator (was BLOCKER) -- FIXED. +page.svelte line 6 imports navigating from $app/stores, and lines 123-127 use {#if $navigating} to render a CSS spinner and "Searching..." text. This is the idiomatic SvelteKit pattern for showing loading state during server-load navigations. The spinner appears while goto() triggers the server load, and disappears when data arrives.

2. Mode toggle auto-search (was BLOCKER) -- FIXED. +page.svelte lines 86-89: the mode button onclick now sets mode = m then conditionally calls doSearch() when there is an active query. This triggers goto() with updated URL params, causing a server-side re-fetch with the new mode. When no query is present, it correctly only updates the visual toggle without firing a search.

Additional fixes observed:

  • Mode validation in +page.server.ts (lines 7-12): validates rawMode against validModes array, defaults to 'hybrid' for invalid values. Good defensive input handling.
  • COLUMNS un-exported in api.ts (line 18): export keyword removed, preventing client-side code from importing a module that references $env/dynamic/private.
  • COLUMNS and COLUMN_COLORS inlined in projects/[slug]/+page.svelte (lines 7-26): eliminates the build error that would have occurred from the server-only import.

ACCEPTANCE CRITERIA AUDIT

  1. /search?q=deploy+recovery shows ranked results with headline snippets -- YES. +page.server.ts reads q from URL params, calls searchNotes(). Results rendered with result.rank.toFixed(3) (line 159) and renderHeadline() using @html (lines 161-164). Headlines sanitized via DOMPurify ($lib/sanitize).

  2. Nav bar search input navigates to /search?q=myquery on Enter -- YES. +layout.svelte line 17: goto(/search?q=${encodeURIComponent(q)}) fires on form submit. Query is properly URI-encoded.

  3. / or Cmd+K focuses search input -- YES. +layout.svelte lines 22-36: svelte:window onkeydown handler checks for / (when not in input/textarea/contentEditable) and Cmd+K/Ctrl+K (unconditionally). Both call navSearchInput?.focus().

  4. Mode toggle updates results and persists in URL -- YES. Mode buttons call doSearch() which builds URL params and navigates via goto(). +page.server.ts reads mode from URL params. $effect on lines 16-21 syncs local state from server data on navigation. Default mode hybrid is omitted from URL params (line 28: mode !== 'hybrid'), keeping URLs clean.

  5. Loading indicator during search -- YES. Verified as described in blocker fix #1 above.

  6. Empty state with search tips -- YES. Lines 174-204: when data.query.q is falsy, renders search mode descriptions and keyboard shortcut tips. No-results state (lines 169-173) also present with "Try different keywords" guidance.

  7. Click result navigates to /notes/{slug} -- YES. Line 137: href="/notes/{result.slug}". The /notes/[slug] route exists on main (+page.svelte and +page.server.ts).

  8. note_type badges use correct typeColor() colors -- YES. Lines 142-154: both the dot indicator and pill badge use typeColor(result.note_type) from $lib/colors. The typeColor() function covers all 16 note types with a #666 fallback for unknowns/nulls.

BLOCKERS

None.

NITS

  1. Headline sanitization order -- renderHeadline() (lines 36-40) converts **word** to <strong> tags before sanitizing. This works correctly because DOMPurify allows <strong> by default, but the comment says "Convert ... then sanitize" which reads like sanitization happens second (it does). Just noting for clarity -- no functional issue.

  2. Duplicate COLUMNS definition -- COLUMNS is now defined in both api.ts (line 18, used by getBoardWithItems) and projects/[slug]/+page.svelte (line 7). This is the correct fix for the build error, but creates a maintenance risk if columns change. Consider extracting to a shared constants file that does not import $env. Non-blocking.

  3. Nav search does not inherit mode -- When using the nav bar search, it navigates to /search?q=... without a mode param, so it always defaults to hybrid. If a user was on the search page with keyword mode selected and uses the nav bar, their mode preference is lost. Very minor UX consideration.
