`94-99`: _🛠️ Refactor suggestion_

**Incomplete error handling in catch block.**

The catch block updates the system info section and incognito status, but doesn't handle the new IP and geolocation sections when an error occurs.

Ensure all UI elements are updated in the error state:

```diff
 catch (error) {
     document.getElementById('result').textContent = 
         'Error: ' + error.message;
     document.getElementById('incognito-status').textContent = 
         'Error detecting';
+    document.getElementById('ip-info').textContent = 
+        'Error: Unable to retrieve IP information';
+    document.getElementById('geo-info').textContent = 
+        'Error: Unable to retrieve geolocation information';
 }
```

`47-116`: _🛠️ Refactor suggestion_

**Duplicate interface definitions that should be imported.**

The interfaces `IpInfo`, `GeolocationInfo`, and `SystemInfo` are defined here but also imported at the top of the file. This creates duplicate definitions which could lead to maintenance issues.

Remove the duplicate interface definitions and rely on the imported types instead. If these definitions are needed in this file as reference, add a comment indicating they are for reference only and are already imported.

```diff
- interface IpInfo {
-     ip: string;
-     network: string;
-     // ... rest of properties
- }
- 
- interface GeolocationInfo {
-     ip: string;
-     country_code: string;
-     // ... rest of properties
- }
- 
- interface SystemInfo {
-     incognito: boolean;
-     userAgent: string;
-     // ... rest of properties
- }
+ // These interfaces are imported from './types' and './geoip'
+ // and are shown here only for reference

<summary>🧹 Nitpick comments (12)</summary><blockquote>

<summary>src/index.ts (1)</summary><blockquote>

`6-17`: **Good implementation of async functionality with proper error handling.**

The updated `userInfo` function now correctly fetches IP and geolocation data asynchronously, with a well-structured try-catch block. This approach ensures that:

1. The function will attempt to gather all information
2. If any API calls fail, it gracefully falls back to returning basic system info
3. Errors are properly logged for debugging



Consider adding a more specific error message when logging failures to better identify which part of the data fetching failed:

```diff
- console.error('Error gathering user info:', error);
+ console.error('Error gathering user info:', error.message || error);
+ console.debug('Error details:', error);
```

</blockquote></details>
<details>
<summary>test/test.html (1)</summary><blockquote>

`83-93`: **Enhanced display logic with proper handling of unavailable data.**

The JavaScript now correctly handles cases where IP or geolocation data might not be available, providing a fallback message. The restructured display logic matches the updated JSON structure returned by the backend.


Consider adding more user-friendly error messages when data is not available:

```diff
- formatJSON(info.ipInfo || { status: 'Not available' });
+ formatJSON(info.ipInfo || { status: 'IP information unavailable', message: 'This might be due to network issues or privacy settings' });

- formatJSON(info.geolocation || { status: 'Not available' });
+ formatJSON(info.geolocation || { status: 'Geolocation unavailable', message: 'This might be due to network issues or privacy settings' });
```

</blockquote></details>
<details>
<summary>src/json.ts (1)</summary><blockquote>

`6-37`: **Well-structured JSON transformation with null-safety.**

The function properly handles transformation of IP and geolocation data, with appropriate null checks. The nested structure provides clear organization of the different data points.


Consider adding a version field to the generated JSON to facilitate future API versioning:

```diff
export function generateJSON(ipInfo: IpInfo | null, geolocationInfo: GeolocationInfo | null, systemInfo: SystemInfo) {
    return {
+       version: "2.0",
        ipInfo: ipInfo ? {
            // existing code
        } : null,
        // rest of the function
    };
}
```

</blockquote></details>

<summary>src/incognito.ts (2)</summary><blockquote>

`2-29`: **Well-implemented incognito detection with multi-browser support.**

The main `isIncognito` function follows a good pattern of running general checks first before falling back to browser-specific checks. The error handling is solid, ensuring the function always returns a boolean result even if detection fails.


Consider adding more descriptive comments for each browser detection strategy and adding a timeout to prevent potential hang situations:

```diff
export async function isIncognito(): Promise<boolean> {
+    // Set a timeout for the entire detection process
+    const timeoutPromise = new Promise<boolean>((_, reject) => {
+        setTimeout(() => reject(new Error('Incognito detection timed out')), 3000);
+    });

+    try {
+        // Run detection with timeout protection
+        return await Promise.race([detectIncognito(), timeoutPromise]);
+    } catch (e) {
+        console.error('Incognito detection error or timeout:', e);
+        return false;
+    }
}

// The main detection logic moved to a separate function
async function detectIncognito(): Promise<boolean> {
    // Run general checks first
    const storageAccess = await checkStorageAccess();
    const quotaLimit = await checkQuotaLimit();

    if (!storageAccess || quotaLimit) {
        return true;
    }

    // Browser-specific checks
    try {
        // Firefox detection
        if (typeof BroadcastChannel === 'undefined' && navigator.userAgent.includes('Firefox')) {
            return true;
        }

        // Safari detection
        if (navigator.vendor.includes('Apple') && (await checkSafariPrivate())) {
            return true;
        }

        // Chrome/Chromium detection
        return await checkChromePrivate();
    } catch (e) {
        console.error('Detection error:', e);
        return false;
    }
}
```

---

`54-67`: **Chrome private browsing detection implementation is thorough.**

The function correctly combines FileSystem API check and quota check for Chrome detection. The Promise-based approach with error handling is well-implemented.


Add explicit type casting for the `window.webkitRequestFileSystem` to avoid potential TypeScript errors:

```diff
async function checkChromePrivate(): Promise<boolean> {
    // Combine FileSystem API check and quota check
    const fsCheck = await new Promise<boolean>(resolve => {
-       const fs = window.webkitRequestFileSystem || (window as any).requestFileSystem;
+       // Explicitly cast the WebKit-specific API
+       const fs = (window as any).webkitRequestFileSystem || (window as any).requestFileSystem;
        if (!fs) return resolve(false);
        
        fs(window.TEMPORARY, 100,
            () => resolve(false),
            () => resolve(true)
        );
    }).catch(() => false);

    return fsCheck || (await checkQuotaLimit());
}
```

These interface definitions (`IpInfo`, `GeolocationInfo`, and `SystemInfo`) are duplicated in this file when they're already being imported from `./geo-ip.js`. Maintaining duplicate definitions can lead to inconsistencies and confusion.

`2-2`: **Fix import path to use TypeScript files directly**

The import statement is referencing the compiled JavaScript file (`./geo-ip.js`) rather than importing directly from the TypeScript source file.

`6-21`: **Consider adding null checks for ipInfo properties**

While you're checking if `ipInfo` itself is null, there's no validation if individual properties within `ipInfo` might be undefined or null before accessing them. This could lead to runtime errors if the API response is incomplete.


```diff

`105-112`: **Add timeout to fetch requests**

The fetch requests don't have a timeout specified, which could lead to hanging connections if the remote APIs are slow to respond or unavailable.


```diff
const response = await fetch(`${PROXY_URL}${GEOIP_URL}`, {
    'method': 'POST',
    'headers': {
        'Content-Type': 'application/json',
        'x-api-key': PROXY_API_KEY || ''
    },
-    'body': JSON.stringify({ ip: ipAddress })
+    'body': JSON.stringify({ ip: ipAddress }),
+    'signal': AbortSignal.timeout(10000) // 10 second timeout
});
```

Apply the same change to the fetch request in `fetchIPInfo`.

`4-4`: **Good improvement on type safety with specific interfaces**

You've replaced `any` types with specific interfaces (`IpInfo | null` and `GeolocationInfo | null`), which improves type safety and code maintainability.

</details>
<details>
<summary>src/geo-ip.ts (2)</summary>

`1-13`: **Good implementation of environment variable handling**

You've properly implemented environment variable configuration with:
- Appropriate default values for missing variables
- Warning messages when critical variables are missing
- Clear fallback URL for the IP API

This improves the robustness of the application in different environments.

---

`15-43`: **Well-defined interfaces for IP and geolocation data**

The interfaces for `IpInfo` and `GeolocationInfo` are now properly defined with all necessary properties, which addresses previous feedback. This improves type safety throughout the application.

**Type imports correctly defined for improved type safety.**

The import statement now correctly references the `IpInfo` and `GeolocationInfo` types from the geoip module, but there's a potential issue with the import path.

---

🏁 Script executed:

```shell
#!/bin/bash
# Check if the geoip module exists or if it should be geo-ip
fd "geo-?ip.(ts|js)" --type file
```

Length of output: 76

</details>

**Attention: Verify the Intended GeoIP Module**

- The type imports in `src/json.ts` are correctly set up for `IpInfo` and `GeolocationInfo`.
- Our search confirms that both `src/geoip.ts` and `src/geo-ip.ts` exist. The current import (`./geoip`) targets `src/geoip.ts`.
- Please double-check that `src/geoip.ts` is the intended source for these type definitions. If the correct module should be `src/geo-ip.ts`, update the import path accordingly.

**Quota limit check has a potential issue with the non-null assertion.**

The function uses a non-null assertion (`quota!`) which could be risky if `quota` is unexpectedly undefined.

Use a safer approach to check the quota value:

```diff
async function checkQuotaLimit(): Promise<boolean> {
    if (!navigator.storage?.estimate) return false;
    
    try {
        const { quota } = await navigator.storage.estimate();
-       // Consider quota < 120MB as incognito (primarily for Chrome)
-       return quota! < 120 * 1024 * 1024;
+       // Check if quota exists and is less than 120MB (primarily for Chrome)
+       return typeof quota === 'number' && quota < 120 * 1024 * 1024;
    } catch {
        return false;
    }
}
```

**Safari private browsing detection has a potential memory issue.**

The function creates a large 1MB string in memory which could be unnecessary and potentially cause issues on memory-constrained devices.

Use a more efficient approach with a smaller test string:

```diff
async function checkSafariPrivate(): Promise<boolean> {
    try {
        const key = 'safari_test';
-       const bigData = new Array(1024 * 1024).join('a'); // ~1MB
+       // Start with a smaller size and increase if needed
+       let testData = 'a'.repeat(100000); // ~100KB
+       
+       // Try to store increasingly larger strings until we hit a limit
+       for (let i = 0; i < 10; i++) {
+           localStorage.setItem(key, testData);
+           // If we can store more, double the size
+           testData = testData + testData;
+       }
+       
        localStorage.removeItem(key);
        return false;
    } catch (e) {
        // Clean up any partial data that might have been stored
+       try { localStorage.removeItem('safari_test'); } catch {}
        return true;
    }
}
```

**Properly define the IpInfo interface.**

The interface contains a placeholder comment rather than actual properties. Define the complete interface to ensure proper type safety.


```diff
export interface IpInfo {
    ip: string;
-    // ... keep other interface properties from geoip.ts
+    city?: string;

}
```

Note: The exact properties should match what's returned by the ipapi.co API.

**Improve error handling and use environment variables for the IP API URL.**

1. The API URL is hardcoded rather than using environment variables.
2. The error handling returns an empty object cast as IpInfo, which can cause runtime errors when properties are accessed.

        });
        if (!response.ok) {
            throw new Error('Geolocation API request failed');
        }
        const data = await response.json();
        return data;
    } catch (error) {
        console.error('Error fetching geolocation information:', error);
-        return {} as GeolocationInfo;
+        // Return a default object with required fields to prevent null references
+        return {
+            ip: ipAddress || 'unknown'
+        };
    }
}
```

Note: I also added a body parameter with the IP address, as it seems this would be needed for a geolocation lookup API.

body: _⚠️ Potential issue_

**Properly define the GeolocationInfo interface.**

The interface contains a placeholder comment rather than actual properties. Define the complete interface to ensure proper type safety.


```diff
export interface GeolocationInfo {
    ip: string;
-    // ... keep other interface properties from geoip.ts
+    continent?: string;
+    country?: string;
+    countryCode?: string;
+    region?: string;
+    regionName?: string;
+    city?: string;
+    district?: string;
+    zip?: string;
+    lat?: number;
+    lon?: number;
+    isp?: string;
+    org?: string;
+    as?: string;
}
```

Note: The exact properties should match what's returned by your geolocation API.

## Walkthrough
The pull request applies major rebranding and refactoring across the project. The README and package metadata have been updated to reflect a new project identity and dependency changes. Several core modules have been enhanced with asynchronous error handling, type safety via new interfaces, and environment-based configuration. The incognito detection logic has been extracted to a separate module, and the UI in the test HTML has been restructured with updated styles for clearer information display. Overall, the changes improve code modularity and robustness while redefining the project's presentation.

## Changes

| README.md, package.json                                          | Rebranding updates: Updated titles, descriptions, repository URLs, version numbers, and dependencies (removed "express" and added "dotenv"). Several documentation sections (Installation, Usage, etc.) have been removed or marked as under construction.                                                                                                  |
| src/geo-ip.ts, src/index.ts, src/json.ts                         | Data fetching and processing improvements: Updated asynchronous functions to return typed Promises using new interfaces (`IpInfo` and `GeolocationInfo`), added error handling for API calls, and restructured JSON generation to improve type safety and clarity.                                                                                           |
| src/incognito.ts, src/systemInfo.ts                             | Incognito detection refactor: Moved incognito checks into a new module (`src/incognito.ts`) with browser-specific and storage-based detection functions, and removed deprecated incognito helper functions from `src/systemInfo.ts` in favor of the new import.                                                                                           |
| test/test.html                                                  | UI update: Introduced new CSS classes to style information sections and updated the HTML structure to separately display Privacy Status, IP Information, Geolocation, and System Information with improved handling of missing data.                                                                                                                     |

> My little paws now spread good cheer.

> A rabbit’s delight in a garden so true.

### 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.
