## Description by Korbit AI

### What change is being made?

Add API Key validation for user authentication, restricting editing features to authenticated users.

### Why are these changes being made?

These changes enhance the application's security by ensuring that only authenticated users can perform critical actions such as creating, editing, or deleting bookmarks and folders. API Key validation is introduced to switch between read-only and full-access modes, emphasizing security and integrity of user data management.

body: Hey @guibranco - I've reviewed your changes - here's some feedback:

**Overall Comments**:
- Consider extracting the API key validation logic into a separate utility function for better reusability and testability.
- The read-only mode indicators are a nice touch, but ensure they don't hinder the user experience for those who don't need the write functionality.

Since this is adding a new property to an existing interface, consider making it optional to ensure backward compatibility with existing code that may not provide this property yet.

<details>
<summary>.vscode/settings.json (1)</summary>

`5-6`: **Good addition for enabling GitHub code scanning integration.**

Adding the SARIF viewer setting is a positive step for integrating security scanning with GitHub, which aligns well with the authentication features being added in this PR.

</details>
<details>
<summary>src/types.ts (1)</summary>

`27-30`: **Well-structured authentication state interface.**

The AuthState interface clearly defines the authentication model with both the boolean flag and the apiKey, which is a good approach for managing authentication across the application.

</details>
<details>
<summary>src/components/BookmarkCard.tsx (5)</summary>

`2-2`: **Appropriate icon import for authentication state indication.**

Adding the Lock icon is a good visual indicator for the unauthenticated state.

---

`9-9`: **Good addition of authentication state prop.**

This new prop enables conditional rendering based on authentication status, which is essential for the API key validation feature.

---

`33-37`: **Well-implemented conditional styling based on authentication.**

The conditional class names provide clear visual feedback to users about the disabled state when not authenticated.

---

`39-39`: **Good accessibility and UX practice with disabled attribute.**

Properly disabling the button when not authenticated prevents user interaction and improves accessibility.

---

`41-47`: **Clear visual indication of authentication state.**

The conditional rendering between Star and Lock icons provides excellent visual feedback to users about the authentication requirements.

</details>
<details>
<summary>src/components/BookmarkList.tsx (4)</summary>

`2-2`: **Appropriate icon import for authentication state indication.**

The Lock icon import is consistent with the approach used in BookmarkCard.

---

`9-9`: **Good addition of authentication state prop.**

Adding the isAuthenticated prop maintains consistency with other components and supports the API key validation feature.

---

`104-104`: **Good accessibility practice with disabled attribute.**

Properly disabling the button when not authenticated prevents user interaction and improves accessibility.

---

`106-112`: **Clear visual indication of authentication state.**

The conditional rendering between Star and Lock icons provides excellent visual feedback to users about authentication requirements, consistent with BookmarkCard implementation.

</details>
<details>
<summary>src/components/Sidebar.tsx (4)</summary>

`2-2`: **Lock icon added for read-only mode indicator.**

The Lock icon import is appropriately added to support the new read-only mode indicator shown to unauthenticated users.

---

`11-11`: **Interface correctly extended for authentication state.**

The `isAuthenticated` boolean property is properly added to the `SidebarProps` interface to support conditional rendering based on authentication status.

---

`158-163`: **Clear read-only mode notification implemented.**

The read-only mode notification provides a clear visual indicator to users when they're not authenticated, with appropriate styling and a lock icon that matches the authentication flow.

---

`231-242`: **Folder creation properly restricted to authenticated users.**

The "Add folder" button is correctly rendered only when the user is authenticated, preventing unauthorized folder creation while maintaining the UI structure.

</details>
<details>
<summary>src/components/BookmarkDetails.tsx (7)</summary>

`2-2`: **Lock icon added for read-only mode indication.**

The Lock icon import is appropriately added to support the new read-only mode indicator.

---

`11-11`: **Interface correctly extended with authentication property.**

The `isAuthenticated` boolean property is properly added to the `BookmarkDetailsProps` interface to support conditional rendering based on authentication status.

---

`100-105`: **Clear read-only mode notification implemented.**

The read-only mode notification provides users with clear feedback about their authentication status, using consistent styling with the sidebar implementation.

---

`118-119`: **Form fields properly disabled for unauthenticated users.**

All input fields are appropriately disabled when the user is not authenticated, with consistent visual styling (reduced opacity and not-allowed cursor) to indicate their disabled state. This is essential for enforcing the read-only behavior.



Also applies to: 134-135, 158-159, 173-174, 199-200, 219-220

---

`225-231`: **Tag addition button properly handled for authentication state.**

The "Add" button for tags is correctly styled based on authentication status, visually indicating when the functionality is disabled.

---

`242-250`: **Tag removal properly restricted to authenticated users.**

The tag removal buttons are correctly only rendered when the user is authenticated, preventing unauthorized modification of bookmarks.

---

`256-275`: **Save and delete actions properly restricted to authenticated users.**

The save and delete buttons are correctly only rendered when the user is authenticated, which is critical for preventing unauthorized modifications or deletions.

</details>
<details>
<summary>src/components/ConfigModal.tsx (6)</summary>

`2-2`: **Key icon added for API key section.**

The Key icon import is appropriately added to provide visual context for the new API key configuration section.

---

`13-13`: **Error state added for API key validation.**

The `apiKeyError` state variable is added to properly track and display validation errors for the API key input.

---

`22-26`: **Error clearing implementation for API key input.**

The error message is appropriately cleared when a user modifies the API key, providing a good user experience during form interaction.

---

`28-32`: **API key validation function implemented.**

The validation function checks that the API key meets minimum length requirements. While this is a basic validation, it's sufficient for the current implementation and the comment indicates that more comprehensive validation would be appropriate in a production environment.

---

`35-40`: **Form submission correctly handles API key validation.**

The `handleSave` function now properly validates the API key before saving the configuration, preventing submission of invalid API keys.

---

`124-148`: **API key configuration UI implemented.**

The API key configuration section is well-implemented with appropriate input field, error message display, and instructional text. The UI maintains consistency with the rest of the application.

---

`39-42`: **Authentication state management implemented.**

The authState state variable is properly implemented to track authentication status and store the API key.

---

`72-80`: **Authentication validation effect added.**

The effect hook appropriately validates the API key length when configuration changes and updates the authentication state accordingly.

---

`124-127`: **User actions properly gated behind authentication checks.**

All bookmark and folder management functions correctly check for authentication before proceeding, redirecting unauthenticated users to the config modal. This is essential for enforcing the application's security model.

---

`355-377`: **Clear authentication warning banner implemented.**

The warning banner for unauthenticated users clearly explains the read-only mode and provides a direct action to add an API key. The design is consistent with other notification elements in the application.

---

`383-391`: **Empty state actions properly restricted based on authentication.**

The "Add Bookmark" button in the empty state is correctly only rendered for authenticated users, maintaining consistency with the application's permissions model.

---

`401-401`: **Authentication state properly passed to child components.**

The isAuthenticated property is correctly passed to all relevant components that need to adapt their UI based on authentication status.

body: **suggestion:** Extract repeated authentication checks into a helper.

The authentication validation (i.e. checking authState.isAuthenticated and invoking setShowConfigModal) is repeated in multiple functions (handleAddBookmark, updateBookmark, deleteBookmark, toggleFavorite, handleAddFolder, createFolder). Consider abstracting this into a dedicated helper or higher-order function to reduce code duplication and improve maintainability.

Suggested implementation:

```typescript
  // Other hooks and component code...

  // Helper function to check authentication and show config modal if not authenticated.
  const requireAuth = (): boolean => {
    if (!authState.isAuthenticated) {
      setShowConfigModal(true);
      return false;
    }
    return true;
  };

```

```typescript
  const handleAddBookmark = () => {
    if (!requireAuth()) return;

```

```typescript
  const updateBookmark = (updatedBookmark: BookmarkType) => {
    if (!requireAuth()) return;

```

Repeat similar refactoring for the following functions: deleteBookmark, toggleFavorite, handleAddFolder, createFolder.
Each of these functions should replace the following pattern:
  if (!authState.isAuthenticated) {
    setShowConfigModal(true);
    return;
  }
with:
  if (!requireAuth()) return;

body: **issue (complexity):** Consider abstracting the repeated ternary logic into a helper function to generate the class name for the disabled state, reducing complexity and improving maintainability

```markdown
Consider abstracting the repeated ternary logic into helper functions or a dedicated component to generate the class name for disabled state. For example, you could create a helper function:

```tsx
const getFieldClasses = (baseClasses: string, isAuthenticated: boolean) =>
  `${baseClasses} ${!isAuthenticated ? 'opacity-75 cursor-not-allowed' : ''}`;
```

Then, update your input (and similar) fields like this:

```tsx
<input
  type="text"
  id="title"
  name="title"
  value={editedBookmark.title}
  onChange={handleChange}
  className={getFieldClasses(
    "w-full px-3 py-2 border border-gray-300 dark:border-gray-600 rounded-md shadow-sm focus:outline-none focus:ring-blue-500 focus:border-blue-500 dark:bg-gray-700", 
    isAuthenticated
  )}
  disabled={!isAuthenticated}
/>
```

This centralizes the disabled styling logic, reducing inline ternaries and overall complexity while keeping functionality intact.

<details>
  <summary>Tell me more</summary>

###### What is the issue?
The API key validation is only checking for length >= 8 characters, which doesn't validate the authenticity of the key.

###### Why this matters
Without proper API key validation against a backend service, any string of 8+ characters would be accepted as valid, potentially allowing unauthorized access to protected features.

###### Suggested change ∙ *Feature Preview*
Implement proper API key validation by making an async call to verify the key with the backend:
```typescript
const validateApiKey = async (apiKey: string): Promise<boolean> => {
  try {
    const response = await fetch('/api/validate-key', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ apiKey })
    });
    return response.ok;
  } catch (error) {
    console.error('API key validation failed:', error);
    return false;
  }
}
```

<details>
  <summary>Tell me more</summary>

###### What is the issue?
The AuthState interface redundantly stores the apiKey that's already present in AppConfig, which could lead to synchronization issues if the values differ.

###### Why this matters
Having the same data (apiKey) in two different states increases the risk of inconsistency where one state might be updated while the other isn't, potentially causing authentication validation failures.

###### Suggested change ∙ *Feature Preview*
Remove apiKey from AuthState and reference it from AppConfig when needed:
```typescript
export interface AuthState {
  isAuthenticated: boolean;
}
```

###### What is the issue?
Delete button directly calls onDelete without confirmation dialog, which could lead to accidental bookmark deletions.

###### Why this matters
Users might accidentally click the delete button and immediately lose their bookmark data without any way to undo the action.

###### Suggested change ∙ *Feature Preview*
Restore the confirmation dialog before deletion:
```typescript
onClick={() => {

    onDelete();
  }
}}
```

## Reviewer's Guide by Sourcery

This pull request introduces API key validation to the bookmark manager application. It adds an API key field to the configuration, validates the key, and restricts bookmark management features to authenticated users. The UI is updated to reflect the authentication status, disabling actions and displaying warnings when the user is not authenticated.

#### Sequence diagram for adding a bookmark with API key validation

```mermaid
sequenceDiagram
    participant User
    participant App
    participant ConfigModal

    User->>App: Clicks 'Add Bookmark'
    alt not authState.isAuthenticated
        App->>ConfigModal: Show ConfigModal
        ConfigModal-->>App: Returns
    else authState.isAuthenticated
        App->>App: Creates new bookmark
        App->>App: Updates bookmarks state
    end
```

#### Updated class diagram for AppConfig and AuthState

```mermaid

    class AppConfig {
        showSidebar: boolean
        darkMode: boolean
        viewMode: string

    }
    class AuthState {
        isAuthenticated: boolean
        apiKey: string
    }
```

## Walkthrough

This pull request introduces a new configuration setting in the VSCode settings and integrates an authentication mechanism across the application. A new API key validation is added, with components adapting their UI elements and interactions based on the user's authentication status. Several components now conditionally disable features such as bookmark management, folder addition, and detail editing when the user is not authenticated. The changes also update TypeScript interfaces to support the new authentication state.

## Changes

| File(s) | Change Summary |
|---------|----------------|
| `.vscode/settings.json` | Added new configuration setting `"sarif-viewer.connectToGithubCodeScanning": "on"`. |
| `src/App.tsx` | Introduced authentication mechanism with `authState`, API key validation, updated `defaultConfig` with `apiKey`, and conditional execution of bookmark/folder functions. |
| `src/components/BookmarkCard.tsx`, `src/components/BookmarkDetails.tsx`, `src/components/BookmarkList.tsx`, `src/components/Sidebar.tsx` | Added new property `isAuthenticated` to component props to conditionally render buttons, icons, and input fields; Sidebar additionally displays a "Read-only mode" message when not authenticated. |
| `src/components/ConfigModal.tsx` | Integrated API key input field with error handling (`apiKeyError`) and a new `validateApiKey` function to enforce a minimum length. |
| `src/types.ts` | Updated `AppConfig` interface to include an `apiKey` property and added a new `AuthState` interface with `isAuthenticated` and `apiKey` properties. |

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
- Add `@coderabbitai` anywhere in the PR title to generate the title automatically.

### CodeRabbit Configuration File (`.coderabbit.yaml`)

- You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository.
- Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information.
- If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json`

### Documentation and Community

- Visit our [Documentation](https://docs.coderabbit.ai) for detailed information on how to use CodeRabbit.
- Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback.
- Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
