## Summary by CodeRabbit

- **New Features**
	- Introduced an authentication enhancement that controls access to sensitive pages. Public pages remain easily accessible, while protected areas now automatically redirect unauthenticated users to the login page, ensuring secure navigation across the app.
	- Added an `AuthProvider` component to provide authentication context to all child components.
	- Introduced new environment variables for site and redirect URLs to enhance configuration.

`33-41`: **Consider simplifying the matcher configuration.**

The current matcher includes both specific routes and a complex catch-all regex pattern, which could lead to confusion and maintenance challenges.


Consider one of these approaches:
1. Separate static asset exclusions from route protection logic
2. Use a more modular approach for defining protected routes

```diff
export const config = {
  matcher: [
    "/board/:path*",
    "/profile",
    "/api/user/:path*",
-   // Add other protected routes here
-   // Exclude authentication paths with negative lookahead
-   "/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)",
+   // Exclude Next.js internal routes and static assets
+   "/((?!_next/static|_next/image|favicon.ico).*)",
  ],
};
```

Alternatively, consider extracting your public and protected paths to constants:

```typescript
// At the top of the file
const PUBLIC_PATHS = ["/", "/api/auth", "/api/kinde-webhook"];
const PROTECTED_PATHS = ["/board/:path*", "/profile", "/api/user/:path*"];
const STATIC_ASSETS_PATTERN = "/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)";

// Then use these constants in your code
export const config = {
  matcher: [...PROTECTED_PATHS, STATIC_ASSETS_PATTERN],
};
```

---

`5-30`: **Consider adding logging for authentication events.**

Adding logging for authentication attempts, successes, and failures would help with debugging and monitoring.


```diff
export async function middleware(request: NextRequest) {
  // Get the pathname of the request
  const path = request.nextUrl.pathname;
+ console.log(`Processing request for path: ${path}`);

  // Exclude public paths from authentication check
  const isPublicPath = [
    "/",
    "/api/auth/:path*",
    "/api/kinde-webhook",
    // Add other public paths here
  ].includes(path);

  if (isPublicPath) {
+   console.log(`Allowing public path: ${path}`);
    return NextResponse.next();
  }

  const { isAuthenticated } = getKindeServerSession();
  if (!(await isAuthenticated())) {
+   console.log(`Unauthenticated request to protected path: ${path}`);
    // Redirect to login page
    const url = request.nextUrl.clone();
    url.pathname = "/api/auth/login";
    return NextResponse.redirect(url);
  }
  
+ console.log(`Authenticated request allowed: ${path}`);
  return NextResponse.next();
}
```

`1-3`: **Imports look good.**

The imports correctly include the necessary Kinde authentication library and Next.js server utilities required for the middleware implementation.

---

`1-43`: <details>
<summary>✅ Verification successful</summary>

**Verify Kinde configuration and integration.**

The middleware relies on the Kinde authentication service. Ensure that Kinde is properly configured in your application and that it's initialized correctly before this middleware runs.

```shell
#!/bin/bash

```

</details>

**Kinde Configuration Verified**

The Kinde integration has been confirmed. The shell scripts verified that:

- Kinde configuration code exists in multiple parts of the codebase.
- The `getKindeServerSession` function is properly referenced outside of the middleware.
- The necessary dependencies are present in `package.json`.
- Relevant Kinde environment variables are defined (e.g., in `.env.example`).

No further changes are required.

`40-40`: <details>
<summary>✅ Verification successful</summary>

**Verify the complex regex pattern.**

The negative lookahead regex pattern is complex and might be difficult to maintain. Ensure it correctly excludes all necessary static assets and Next.js internal routes.

```

Length of output: 940

</details>

**Regex verification passed – No changes required.**

I executed additional tests using a Python script that applies the regex pattern to a variety of paths. The results confirmed that:

- Paths starting with `/_next` (e.g. `/_next/static/chunks/main.js`, `/_next/image?url=test.jpg`) and files with static asset extensions (e.g. `/favicon.ico`, `/images/logo.png`, `/styles.css`, `/script.js`) are correctly excluded.
- Routes like `/api/auth/login`, `/api/kinde-webhook`, `/board/123`, and `/profile` are allowed.
- Noticeably, `/document.pdf` is allowed because the exclusion list only comprises the explicitly listed extensions. If public access to PDFs is not desired, consider updating the exclusion list accordingly.

The regex pattern is working as intended based on the current requirements.

`1-6`: _⚠️ Potential issue_

**Add error handling for authentication middleware and address unused parameter warning.**

While the `withAuth` middleware simplifies implementation, there's no error handling for authentication failures, and the ESLint warning about the unused parameter should be addressed.



```diff
-export default withAuth(async function middleware(_: NextRequest) {}, {
+export default withAuth(async function middleware(request: NextRequest) {
+  try {
+    // Your additional middleware logic here if needed
+    return undefined; // Continue with the request
+  } catch (error) {
+    console.error("Authentication middleware error:", error);
+    // Redirect to login or error page
+    return Response.redirect(new URL("/api/auth/login", request.url));
+  }
+}, {
  publicPaths: ["/", "/api/kinde-webhook"],
});

`5-5`: _⚠️ Potential issue_

**Improve public path handling for more flexible matching.**

The current implementation only handles exact matches for public paths. It should be updated to handle pattern matching for paths that might include dynamic segments or wildcards.



```diff
-  publicPaths: ["/", "/api/kinde-webhook"],
+  publicPaths: (path: string) => {
+    // Check if the path is in the list of public paths
+    return path === "/" || 
+           path === "/api/kinde-webhook" || 
+           path.startsWith("/api/auth/");
+  },
```

This function-based approach allows for more flexible path matching logic, including prefix matching and pattern recognition.

`12-14`: **Minor stylistic change to dynamic imports.**

The dynamic imports for `SpeedInsights` and `VercelToolbar` have been reformatted with template literals. This is a stylistic change that doesn't affect functionality.


For consistency, consider using the same import style throughout the codebase.

```

This enhancement provides fallbacks for local development environments, ensuring the application works correctly during development without relying on Vercel-specific environment variables.

<summary>components/common/AuthProvider.tsx (1)</summary>

`1-7`: **Good implementation of the authentication provider wrapper.**

The `AuthProvider` component correctly wraps the application with the `KindeProvider` from `@kinde-oss/kinde-auth-nextjs`, ensuring authentication context is available to all child components. The component is properly set up as a client component with the "use client" directive, and it correctly types the children prop using ReactNode.

</details>
<details>
<summary>app/layout.tsx (1)</summary>

`1-1`: **Good integration of the AuthProvider in the root layout.**

The `AuthProvider` component is correctly imported from the local components directory and properly wraps the entire application layout, ensuring authentication is available throughout the application hierarchy.

`8-12`: **Good use of matcher pattern to exclude static assets and internal routes.**

The matcher pattern effectively excludes Next.js internal routes and static assets from middleware processing, which is a good practice for performance.

Please add a dedicated section in your documentation (such as the README) explaining the purpose, expected values, and configuration details for the following variables:

- **KINDE_SITE_URL**
- **KINDE_POST_LOGOUT_REDIRECT_URL**
- **KINDE_POST_LOGIN_REDIRECT_URL**

This will help new developers configure the application correctly.

## Walkthrough
A new middleware function has been introduced in a Next.js application to manage authentication. It checks if a request's pathname is public; if so, it allows the request to proceed. For non-public paths, the middleware verifies the authenticated session using a helper function. If the session is absent, it redirects the user to the login page. Additionally, an `AuthProvider` component has been added to wrap the layout, providing authentication context to all child components. Environment variables for site URLs and redirect URLs have also been defined in the configuration.

## Changes
| File(s)                            | Change Summary                                                                                                                                               |
|------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `middleware.ts`                    | Added a new `middleware` function that handles route authentication by differentiating public and non-public paths, and added an exported `config` object. |
| `app/layout.tsx`                   | Introduced an `AuthProvider` component wrapping the layout to provide authentication context; reformatted dynamic imports for consistency.                    |
| `components/common/AuthProvider.tsx` | Created a new `AuthProvider` component that wraps its children with `KindeProvider` for authentication context.                                             |
| `next.config.js`                   | Added an `env` object with new environment variables: `KINDE_SITE_URL`, `KINDE_POST_LOGOUT_REDIRECT_URL`, and `KINDE_POST_LOGIN_REDIRECT_URL`.             |

## Sequence Diagram(s)
```mermaid

        MW->>Req: NextResponse.next()
    else Request is non-public
        MW->>Auth: getKindeServerSession(request)
        alt Session found
            Auth-->>MW: Session Info
            MW->>Req: NextResponse.next()
        else No session found
            Auth-->>MW: No session
            MW->>LP: Redirect to login
        end
    end
```

## Poem
> I'm just a bunny in the code warren,  
> Hopping through routes with a clever plan,  
> Checking paths with carrot-eyed precision,  
> Redirecting lost ones with swift decision,  
> Happy to nibble on middleware magic—yum! 🥕🐇  
> Hop-hop hooray for our fresh new addition!

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=DW225/ree-board&utm_content=200):

- 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.
