Description

This PR addresses multiple frontend issues related to Accessibility, Internationalization (i18n), and UI consistency.

Key Changes:

  • Accessibility:
    • Added missing id, name, and autoComplete attributes to various input fields (Transformation Dialog, Notebook Dialog, etc.) to resolve accessibility warnings and improve screen reader support.
    • Fixed missing label associations for the MarkdownEditor component by introducing a textareaId prop.
    • Added DialogDescription to dialogs to satisfy Radix UI accessibility requirements.
  • Internationalization (i18n):
    • Added missing translation keys for podcastProfiles in all locale files (en-US, zh-CN, zh-TW).
    • Updated GeneratePodcastDialog to use these translated strings.
    • Fixed a duplication issue in the Language Menu where "Traditional Chinese" appeared twice due to an incorrect translation string in zh-TW (Corrected common.chinese to "简体中文").
  • UI & Code Quality:
    • Resolved a "Collapsible is changing from uncontrolled to controlled" warning in SettingsForm by correctly initializing state.
    • Fixed various linting errors (e.g., DialogDescription import, @ts-expect-error usage).

<file name="frontend/src/components/layout/__tests__/AppSidebar.test.tsx">

<violation number="1" location="frontend/src/components/layout/__tests__/AppSidebar.test.tsx:45">
P1: Test is incomplete - clicks the toggle button but never asserts that `toggleCollapse` was called. Add an assertion like `expect(toggleCollapse).toHaveBeenCalled()` after the click event.</violation>

<violation number="2" location="frontend/src/components/layout/__tests__/AppSidebar.test.tsx:62">
P2: Incorrect text pattern - the first test uses `/Open Notebook/i` as the app name, but this test checks for `/AppName/i`. The assertion will always pass for the wrong reason. Should check for the actual app name.</violation>
</file>

<file name="frontend/src/components/common/ConnectionGuard.tsx">

<violation number="1" location="frontend/src/components/common/ConnectionGuard.tsx:20">
P1: Re-entry prevention logic is ineffective. The condition guards only the state update, but the function continues executing all async operations regardless. To actually prevent re-entry, add an early return when already checking.</violation>
</file>

<file name="frontend/src/app/(dashboard)/sources/page.tsx">

<violation number="1" location="frontend/src/app/(dashboard)/sources/page.tsx:280">
P2: String splitting by `.` will fail for Chinese locales which use `。` (full-width period). This will display the full description instead of just the first sentence. Consider adding a separate translation key for the short description (e.g., `t.sources.noSourcesShortDesc`) rather than manipulating translated strings.</violation>
</file>

<file name="frontend/src/app/(dashboard)/transformations/components/TransformationPlayground.tsx">

<violation number="1" location="frontend/src/app/(dashboard)/transformations/components/TransformationPlayground.tsx:60">
P2: Using `.replace(&#39;s&#39;, &#39;&#39;)` to derive singular form from a translation is an i18n anti-pattern. In Chinese, `navigation.transformations` = &quot;转换&quot; has no &#39;s&#39; to remove. Create a dedicated translation key like `t.transformations.singular` or `t.navigation.transformation` for the singular form.</violation>

<violation number="2" location="frontend/src/app/(dashboard)/transformations/components/TransformationPlayground.tsx:81">
P2: Using `t.settings.embeddingOptionPlaceholder` (&quot;Select embedding option&quot;) is semantically incorrect here since this is a language model selector (`modelType=&quot;language&quot;`). Consider creating a more generic translation key like `t.transformations.selectModel` or use a model-specific placeholder.</violation>
</file>

<file name="frontend/src/components/common/CommandPalette.tsx">

<violation number="1" location="frontend/src/components/common/CommandPalette.tsx:47">
P2: Concatenating translated strings is an i18n anti-pattern. In Chinese, this will produce &quot;新建 来源&quot; with an unnatural space. Use dedicated translation keys like `common.newSource`, `common.newNotebook`, `common.newPodcast` that can be properly localized for each language.</violation>
</file>

<file name="frontend/next.config.ts">

<violation number="1" location="frontend/next.config.ts:7">
P1: Disabling ESLint and TypeScript error checks during builds is a dangerous practice that allows broken code to be deployed. These flags mask errors rather than fix them, which contradicts the PR&#39;s stated goal of fixing issues.

If there are legitimate build errors, they should be fixed at the source. If certain rules need temporary exceptions, use inline comments (e.g., `// eslint-disable-next-line`) for specific cases rather than project-wide suppression.

Please remove these flags and fix any underlying ESLint/TypeScript errors instead.</violation>

P2: Pluralization is lost: will show &quot;Used by 1 episodes&quot; instead of &quot;Used by 1 episode&quot;. Consider using react-i18next&#39;s built-in pluralization with `_one`/`_other` suffixes, or add separate singular/plural translation keys.</violation>

<violation number="1" location="frontend/src/components/podcasts/GeneratePodcastDialog.tsx:733">
P2: Locale handling for `zh-TW` is incorrect. Traditional Chinese users will see English date formatting instead of Chinese. The ternary only checks for `zh-CN`, causing `zh-TW` to fall through to `en-US`.</violation>
</file>

<file name="frontend/src/app/(dashboard)/notebooks/components/NotebookHeader.tsx">

<violation number="1" location="frontend/src/app/(dashboard)/notebooks/components/NotebookHeader.tsx:115">
P1: The `.replace(&#39;{time}&#39;, ...)` calls will have no effect because the translation strings `t.common.created` and `t.common.updated` don&#39;t contain a `{time}` placeholder. The locale file has `created: &quot;Created&quot;` and `updated: &quot;Updated&quot;` without placeholders, so the formatted time will not be displayed.

The translation strings should be updated to include the placeholder, e.g., `created: &quot;Created {time}&quot;` and `updated: &quot;Updated {time}&quot;`.</violation>
</file>

<file name="frontend/src/app/(dashboard)/notebooks/components/SourcesColumn.tsx">

<violation number="1" location="frontend/src/app/(dashboard)/notebooks/components/SourcesColumn.tsx:165">
P2: Incorrect translation key used: the dropdown menu item was originally &#39;Add New Source&#39; but now uses the same key as the button (&#39;Add Source&#39;). Use `t.sources.addNew` instead to preserve the original distinction.</violation>
</file>

<file name="frontend/src/app/(dashboard)/transformations/components/TransformationCard.tsx">

<violation number="1" location="frontend/src/app/(dashboard)/transformations/components/TransformationCard.tsx:91">

P1: Translation keys `t.notebooks.archived`, `t.notebooks.archive`, `t.notebooks.unarchive`, `t.notebooks.deleteNotebook`, and `t.notebooks.deleteNotebookDesc` do not exist in the locale files. The notebooks section only defines `title`, `newNotebook`, and `searchPlaceholder`. These missing keys need to be added to all locale files.</violation>

<violation number="1" location="frontend/src/components/source/MessageActions.tsx:23">
P2: Using generic `t.common.error` (&quot;Error&quot;) instead of specific error messages loses important context for users. The original message &quot;Cannot save note: notebook ID not available&quot; was much more informative. Consider creating a specific translation key like `t.sources.cannotSaveNoteNoNotebook` to preserve the helpful error context.</violation>

Configuration:
- Remove ignoreDuringBuilds flags from next.config.ts

Testing:
- Fix AppSidebar.test.tsx regex pattern and add missing assertion

Logic:
- Fix ConnectionGuard.tsx re-entry prevention logic

Internationalization (I18n) - Translations:
- Add missing keys: notebooks.archived, common.note/insight, accessibility keys
- Add specific keys: sources.allSourcesDescShort, transformations.selectModel
- Add singular/plural keys: podcasts.usedByCount_one/other, common.note/notes
- Add common.created/updated with {time} placeholder

Internationalization (I18n) - Usage:
- SourcesPage: use allSourcesDescShort instead of string splitting
- TransformationPlayground: use navigation.transformation and selectModel
- CommandPalette: use dedicated keys instead of string concatenation
- GeneratePodcastDialog: fix zh-TW date locale handling
- NotebookHeader: correctly interpolate {time} placeholder
- TransformationCard: use common.description instead of undefined key
- ChatPanel/SpeakerProfilesPanel: implement proper pluralization
- SystemInfo: correctly interpolate {version} placeholder
- LanguageLoadingOverlay: use t.common.loading instead of hardcoded string
- MessageActions: use specific error key cannotSaveNoteNoNotebook

Other:
- Fix SessionManager.tsx exhaustive-deps warning

@MisonL wow.. this is such a great work. I am really excited to push this change to production, but we had a lot of new pushes to the codebase after the PR was created. Do you mind refreshing your branch with the latest main version and going through the conflicts so we can test and approve this PR? I promise to be quick once you do it :)

Comprehensive Improvements: i18n, Accessibility, and Backend Remediation

This PR provides a full internationalization (i18n) framework, extensive accessibility (A11y) fixes, and critical architectural remediations based on recent code review findings.

Key Changes

1. Internationalization (i18n) & Localization

  • Multi-language Support: Full support for zh-CN (Simplified Chinese) and zh-TW (Traditional Chinese) with restructured locale indices.
  • Robust Hook Implementation: Introduced a custom useTranslation hook with a proxy-based safety mechanism to prevent infinite rendering loops and ensure thread safety during language switching.
  • UI Components: Added LanguageToggle and LanguageLoadingOverlay for seamless switching between 100% localized frontend pages.

2. Accessibility (A11y) & UI Consistency

  • Label Associations: Resolved over 20 instances of unassociated labels by correctly mapping htmlFor and unique id attributes across dialogs and forms.
  • Enhanced Form Attributes: Added missing name, autoComplete, and DialogDescription attributes to comply with Radix UI and screen reader standards.
  • UI Polish: Optimized sidebar hover effects and improved the language matching logic for flexible region highlighting (e.g., matching both zh-Hans and zh-CN).

3. Backend Architecture & Security (PR Remediations)

  • Security Sanitization: Replaced raw internal exceptions with generic, secure error messages in all API routers to prevent data leakage.
  • Async I/O Refactor: Converted the version check in /api/config to use an asynchronous httpx client, eliminating 10s blocking I/O calls that were previously freezing the event loop.
  • FastAPI Standards: Fixed dependency injection in auth.py and ensured the custom exception handler correctly merges existing headers (e.g., WWW-Authenticate) with CORS headers.

4. DevOps, Build & Testing

  • Docker Optimization: Introduced .dockerignore and optimized multi-stage builds. Frontend dependencies are now cached separately, and image size is significantly reduced by excluding build tools from the runtime stage.
  • Frontend Testing: Integrated Vitest for unit testing. Added comprehensive test coverage for hooks (use-translation, use-modal-manager), configuration priority, and localized UI components.
  • Engineering Standards: Applied Ruff formatting and resolved multiple TypeScript type conflicts and IDE resolution errors in tsconfig.json.

Verification Status

  • All 37 PR findings from the AI review bot addressed and verified.
  • Full i18n coverage tested across all core business modules.
  • Accessibility score improved; console warnings resolved.
  • Docker build and deployment verified.

This is an absolutely amazing contribution. I am very grateful for your help. I made some comments here that should be pretty straightforward to address. Can we make these changes?

I am concerned that removing upgrade could expose the app to vulnerability. Why did you propose this? Any special reason?

Mock of useTranslation is different from the one used in ConfirmDialog.test.tsx - inconsistency. Risk: Global mocks can mask bugs (tests pass but real code fails)

Suggestion: simplify to just one effect.

  export function useVersionCheck() {
    const { t } = useTranslation()
    const hasChecked = useRef(false)

    useEffect(() => {
      if (hasChecked.current) return
      hasChecked.current = true

      getConfig()
        .then(config => {
          if (!config.hasUpdate || !config.latestVersion) return

          const dismissKey = `version_notification_dismissed_${config.latestVersion}`
          if (sessionStorage.getItem(dismissKey)) return

          toast.info(t.advanced.updateAvailable.replace('{version}', config.latestVersion), {
            description: t.advanced.updateAvailableDesc,
            duration: Infinity,
            closeButton: true,
            action: {
              label: t.advanced.viewOnGithub,
              onClick: () => window.open('https://github.com/lfnovo/open-notebook', '_blank'),
            },
            onDismiss: () => sessionStorage.setItem(dismissKey, 'true'),
          })
        })
        .catch(() => {}) // Silently fail
    }, [t]) // t ainda é dependência mas só executa uma vez pelo ref guard
  }

Benefits:

  • A single useEffect, linear flow easy to follow
  • No need for state (useState) - less re-renders
  • hasChecked.current guarantees single execution even if t changes
  • Less code (~30 lines vs ~50 lines of PR)

Accepted trade-off: Toast does not update language in real time (not a real problem).

- Docker: consolidate SURREAL_URL to docker.env, add single-container override
- Security: restore apt-get upgrade in Dockerfile and Dockerfile.single
- Create centralized getDateLocale helper (lib/utils/date-locale.ts)
- Refactor 7 files to use getDateLocale helper
- Revert config/route.ts to origin/main version
- Move test files to co-located pattern (3 files)
- Remove local useTranslation mock from ConfirmDialog.test.tsx
- Simplify use-version-check to single useEffect pattern
- Fix test import paths after moving to co-located pattern
- Add apt-get upgrade -y to Dockerfile.single backend-builder stage
- Refactor ChatColumn.test.tsx: use 'as unknown as ReturnType<typeof hook>' instead of 'as any'
- Use toBeInTheDocument() assertions instead of toBeDefined()

PR #371 Review Feedback - Changes Summary

1. Docker Environment Consolidation ✅

  • Moved SURREAL_URL from inline environment: blocks to docker.env
  • docker.env now defaults to ws://surrealdb:8000/rpc (multi-container mode)
  • Added override in docker-compose.single.yml for single-container mode (ws://localhost:8000/rpc)

2. Security: Restored apt-get upgrade

  • Dockerfile: Restored apt-get upgrade -y in runtime stage
  • Dockerfile.single: Added apt-get upgrade -y in both backend-builder and runtime stages
  • Removed misleading "upgrade removed" comment

3. Centralized Date-Locale Helper ✅

  • Created frontend/src/lib/utils/date-locale.ts with getDateLocale(language) function
  • Refactored 7 files to use the helper (eliminates repetitive ternary expressions):

Note on apt-get upgrade: I apologize for initially removing it. The reason was that Docker builds were taking nearly 20 minutes on my local environment, and I wanted to speed up the development iteration cycle. I understand this is not acceptable from a security perspective, and I have now restored apt-get upgrade -y in both Dockerfile and Dockerfile.single.

Thank you so much! I really saw the potential of this project and wanted my friends—who aren't as comfortable with English—to be able to enjoy a smooth experience. That's what motivated me to contribute this PR.

I should also give credit to Antigravity and Codex, which were incredibly helpful throughout the process.

Oh, and I don't have a Reddit account, so no need to mention me there—haha! 😄

Thanks again for the warm welcome! 🙏
