📝 Walkthrough

Walkthrough

The changes extend database schema with optional columns for categories and asset filters, introduce comprehensive API type definitions, implement DELETE routes for repositories and releases with transactional cleanup, update URL-building logic to handle existing version prefixes, enhance the header with responsive mobile navigation and state-driven text wrapping detection, improve the AI config panel with testing capabilities and prompt management, and adjust responsive layout breakpoints and styling across multiple UI components.

Changes

Cohort / File(s)	Summary
Database Schema Extensions server/src/db/schema.ts	Added optional columns (description, color, sort_order) to categories table and (description, platform, sort_order) to asset_filters table with corresponding ALTER TABLE migrations.
API Type Definitions server/src/types/api.ts	Introduced new TypeScript interfaces for database row models (RepositoryRow, ReleaseRow, CategoryRow, AIConfigRow, WebDAVConfigRow, AssetFilterRow, SettingsRow), API envelope types (ApiResponse<T>, PaginatedResponse<T>), and sync request payloads for repositories, releases, AI configs, WebDAV configs, and settings.
Server Routes — Deletion Operations server/src/routes/releases.ts, server/src/routes/repositories.ts	Added DELETE route handlers: /api/releases/:id with validation and error handling, and /api/repositories/:id with transactional deletion of related releases and the repository itself.
URL Building Logic server/src/routes/proxy.ts, src/services/aiService.ts	Updated buildApiUrl() in both files to detect version segments in baseUrl (matching /v\d+ with optional alpha/beta) and strip duplicate version prefixes from composed endpoint paths.
Frontend Component Layout & Responsiveness src/components/Header.tsx, src/components/RepositoryCard.tsx, src/components/RepositoryList.tsx, src/components/SearchBar.tsx	Refactored Header with React hooks, mobile dropdown menu, and ResizeObserver-based text wrapping detection; adjusted RepositoryCard drag-handle visibility to hidden on small screens; updated RepositoryList grid breakpoints (md:grid-cols-2, lg:grid-cols-3); clarified SearchBar AI button tooltip and added help popover explaining local ranking behavior.
AI Configuration UI & Testing src/components/settings/AIConfigPanel.tsx	Enhanced with state for form testing, default prompt display, notifications, and memoized prompt comparison; added "Test Connection" button with loading state, prompt restoration with confirmation, custom/default prompt toggle logic, and metadata display for custom prompts.
Frontend Services & Styling src/services/backendAdapter.ts, src/index.css	Added isFullSync: true field to repository sync request payload; added responsive CSS rule disabling drag behavior on screens below 1024px.

🐰 Hopping through schemas and routes so neat,
Building menus where mobile and desktop will meet,
AI prompts tested, drag zones refined,
Type definitions and versions aligned—
A pull request bundled with care, I'd say! ✨

Inline comments:
In `@server/src/routes/releases.ts`:
- Around line 182-185: The handler currently uses parseInt(req.params.id) which
accepts partial/decimal inputs; change the validation around the parse step in
the DELETE release route (the code using parseInt and req.params.id) to only
accept a strictly positive integer string (e.g. test req.params.id against a
/^\d+$/ pattern or verify String(req.params.id) ===
String(Number(req.params.id)) and Number.isInteger) before calling
parseInt/Number; if the check fails respond with 400 and code
'INVALID_RELEASE_ID' so inputs like "1abc" or "1.9" are rejected.

In `@server/src/routes/repositories.ts`:
- Around line 258-264: The transaction currently throws an Error when
repoResult.changes === 0 which causes the catch to map it to a 500; instead,
detect "not found" outside the transaction so you can return a 404. Change the
flow around deleteAll/db.transaction: have the transaction perform
deleteReleases.run(id) and deleteRepo.run(id) and return the repoResult (or
number of changes) from the transaction, then after the transaction completes
check the returned repoResult.changes (or changes count) and if it's 0 send a
404 with code REPOSITORY_NOT_FOUND; do the same adjustment for the other delete
block that uses deleteRepo/deleteReleases so not-found is handled outside the
transaction rather than by throwing inside it.
- Around line 248-251: The current parseInt(req.params.id) allows partial/float
inputs like "1abc" or "1.9" to become 1 — change validation to strictly accept
only positive integer strings (e.g. using a regex like /^\d+$/ or
Number.isInteger on the parsed value after confirming the string is all digits),
reject any non-matching req.params.id with the same 400/INVALID_REPOSITORY_ID
response, and only then convert the validated string to a Number to use as the
id in the delete transaction (ensure references to parseInt(req.params.id) and
the id variable in the delete handler/transaction are replaced with this
validated conversion).

In `@server/src/types/api.ts`:
- Around line 15-22: The DTO/row interface defines several properties as plain
string while the DB schema marks them nullable; update the interface fields
(topics, ai_summary, ai_tags, ai_platforms, analyzed_at, analysis_failed,
custom_description, custom_tags) to reflect DB nullability (use string | null
for nullable text columns and preserve number type for numeric columns but allow
null if schema marks them nullable), and apply the same fixes to the other row
interfaces referenced in the comment (the occurrences at the other locations
noted) so all shared row types match the schema nullability.

In `@src/components/Header.tsx`:
- Around line 177-217: The icon-only buttons (repositories, releases, settings)
render without accessible labels when isTextWrapped is true; update each
<button> that uses setCurrentView and icons (Search, Calendar, Settings) to
include an aria-label and title when isTextWrapped is true (e.g., use the
existing t('仓库','Repositories') / t('发布','Releases') / t('设置','Settings')
strings) so the icon-only fallback remains accessible and provides the same
localized label as the visible text.

In `@src/components/SearchBar.tsx`:
- Around line 803-820: The UI copy claims "Not actually calling LLM, uses local
intelligent ranking algorithm" but the search path in SearchBar.tsx still calls
aiService.searchRepositoriesWithReranking via handleAISearch when an active AI
config exists; either make the code truly local by removing/guarding calls to
aiService.searchRepositoriesWithReranking (use the local ranking function
instead) or update the copy and tooltip strings (the title and "关于AI搜索"/"This
feature..." text) to accurately state that the feature may call the configured
AI service when present; locate handleAISearch and
aiService.searchRepositoriesWithReranking to implement the chosen fix and update
the displayed text keys shown around the Bot and AlertCircle UI.

In `@src/components/settings/AIConfigPanel.tsx`:
- Around line 164-179: The test is using a fake id ('temp-test') so
AIService.requestText falls back to backend.proxyAIRequest when
backend.isAvailable && config.id, which can cause backend lookup of a saved
config instead of testing the current unsaved form; update the test flow in
AIConfigPanel.tsx to ensure testConnection uses the actual unsaved form values
by either (A) calling AIService.testConnection with a config that has no id
(remove or set id to undefined/null) so backend.proxyAIRequest is not triggered,
or (B) implement/route to a dedicated backend proxy that accepts the full temp
config payload; modify the code that constructs tempConfig (AIConfig) and the
AIService invocation (new AIService(tempConfig, language).testConnection()) so
backend.isAvailable && config.id does not resolve the request to a saved-config
lookup.
- Around line 42-45: The current showNotification in AIConfigPanel schedules a
new timeout each call which allows an older timer to clear a newer notification;
update showNotification to cancel any existing timer before creating a new one
by storing the timeout id in a ref (e.g., notificationTimerRef) and calling
clearTimeout(notificationTimerRef.current) prior to setTimeout, set
notificationTimerRef.current to the new id, and also clear the ref and timer on
component unmount (useEffect cleanup); reference the showNotification function,
setNotification state, and the new notificationTimerRef when making the change.
