loggedIn.value always false
I'm actually new to Nuxt. I tried the tutorial for authentication, and it works well on my computer with docker. When I try to deploy it on my vps, I have an issue with it. loggedIn.value is always false. I check my authentication api, and it doesn't throw an error. I check the server side of nuxt and there is no error too. I can provide code if needed. I'm really confused now.

Hi @Endeau.pro. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in the knowledge sources, I can offer some insights and suggestions regarding your issue with
loggedIn.value always being false in your deployed Nuxt application.
1. First, it's important to note that authentication state can be tricky to manage, especially when deploying to a different environment. The fact that it works locally but not on your VPS suggests there might be some environment-specific issues.
2. The loggedIn value is typically managed by the useUserSession composable provided by the nuxt-auth-utils module. Make sure you have this module properly installed and configured in your production environment. Docs > Guide > Recipes > Sessions and Authentication provides information on setting this up.
3. Check if you have properly set the NUXT_SESSION_PASSWORD environment variable on your VPS. This is crucial for encrypting session cookies. As mentioned in the Docs > Guide > Recipes > Sessions and Authentication > Cookie Encryption Key, you need to add this environment variable to your production environment before deploying.
4. Ensure that your login API route is working correctly on the server. The setUserSession function should be called successfully after validating credentials. You can add some logging in your API route to verify this.
5. If you're using client-side middleware to check authentication status, make sure it's properly implemented. The Docs > Guide > Recipes > Sessions and Authentication > Protect App Routes shows an example of how to do this.
6. Consider using the refreshCookie function if you're setting cookies on the server and need to update the client-side state. As mentioned in the Docs > Api > Utils > refreshCookie, this can be useful for updating the useCookie ref when you know the new cookie value has been set in the browser.
7. If you're still having issues, you might want to add some debugging code. For example, you could log the value of loggedIn in various parts of your application to see where it's being set or changed.
If you've checked all these points and are still experiencing issues, it would indeed be helpful to see your code, particularly your authentication API route and how you're using the useUserSession composable in your components.
Remember, when dealing with authentication, it's crucial to ensure that your server-side routes are also protected. The client-side checks are mainly for user experience, but server-side protection is essential for security.
If you continue to face problems, you might want to consider asking for help in the Nuxt GitHub Discussions, as suggested in the Docs > Community > Getting Help. The Nuxt community is generally very helpful and might be able to provide more specific guidance based on your particular setup.

Thank you for providing your
login.post.ts code. I'll analyze it and provide some insights based on the knowledge sources available.
Your code seems to be implementing a login endpoint that validates the request body, forwards the authentication request to a backend service, and sets a user session upon successful authentication. However, there are a few points to consider:
1. Body Validation: You're using Zod for request body validation, which is good practice. However, you're using readBody instead of readValidatedBody. The Examples > Validate Body suggests using readValidatedBody for a more streamlined approach:
This would simplify your code and remove the need for the manual safeParse check.
2. Session Handling: You're using setUserSession, which is correct according to the Docs > Guide > Recipes > Sessions and Authentication > Login API Route. However, you're setting a static user object instead of using the data from the backend response.
3. Error Handling: Your error handling looks good, but you might want to consider passing the error message from the backend to provide more specific feedback.
4. Logging: While logging is helpful for debugging, make sure to remove or disable console logs in production, especially those containing sensitive information.
5. Backend URL: Ensure that the URL '<http://laura-s-website-backend:3000/api/auth/login'> is correct and accessible from your server environment.
To address the issue of loggedIn.value always being false, consider the following:
1. Verify that the setUserSession call is actually being reached. Add a log statement right before and after this call to ensure it's executed.
2. Check if the cookie is being set correctly. You can inspect the response headers in your browser's network tab to see if the Set-Cookie header is present.
3. On the client side, after login, you might need to refresh the session data. The Stack Overflow Post > How do I access useState inside middleware in Nuxt 3? suggests using:
You could adapt this to update your authentication state after a successful login.
4. If you're using middleware to check authentication status, ensure it's correctly implemented and not running on the server side if it's not meant to. The Stack Overflow Post > How to use Nuxt VueFire Session Cookie with App Check and browser key restrictions? Part 4 shows an example of how to skip middleware on the server or initial client load.
If you're still experiencing issues after these adjustments, you might want to check your server logs for any errors related to cookie setting or session management. Also, ensure that your VPS environment has all the necessary configurations, including the NUXT_SESSION_PASSWORD as mentioned in the previous response.

@kapa.ai I have set-cookie with nuxt-session=...
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on the information you've provided and the knowledge sources available, it appears you're dealing with session cookies in your Nuxt application. The presence of a
nuxt-session cookie suggests that you're using Nuxt's built-in session management, likely through the nuxt-auth-utils module or a similar authentication setup.
Here are some key points to consider:
1. Cookie Presence: The fact that you see a set-cookie header with nuxt-session indicates that your server is attempting to set a session cookie. This is a good sign and suggests that your authentication process is at least partially working.
2. Cookie Encryption: As mentioned in the Docs > Guide > Recipes > Sessions and Authentication > Cookie Encryption Key, make sure you have set the NUXT_SESSION_PASSWORD environment variable in your production environment. This is crucial for properly encrypting and decrypting the session cookie.
3. Cookie Refresh: If you're setting the cookie on the server but not seeing the updated value on the client, you might need to manually refresh the cookie. The Docs > Api > Utils > refreshCookie utility can help with this:
4. Server-Side Cookie Handling: If you're setting cookies in server-side API routes, make sure you're properly handling them. The Docs > Getting-started > Data Fetching > Passing Headers and Cookies provides an example of how to pass cookies from server-side API calls to the SSR response:
5. Client-Side Session Management: On the client side, you can use the useUserSession composable to manage the session state. Make sure you're correctly updating this state after successful authentication.
If you're still experiencing issues with your session management or authentication process, it would be helpful to know more about:
- Where exactly you're setting this cookie (e.g., in a login API route, middleware, etc.)
- How you're trying to access or use the session data on the client side
- Any specific errors or unexpected behaviors you're encountering
Remember, while client-side checks are important for user experience, always ensure that your server-side routes are properly protected for security. If you continue to face difficulties, consider reaching out to the Nuxt community through their official channels for more specific assistance.

Thank you for providing your login view page code. I'll analyze it based on the knowledge sources available and provide some insights.
Your login view implementation looks generally correct and follows the structure suggested in the Docs > Guide > Recipes > Sessions and Authentication > Login Page. However, there are a few points to consider:
1. Middleware: You're using a
not-authenticated middleware, which is not a standard Nuxt middleware. Make sure you have defined this middleware correctly to prevent authenticated users from accessing the login page.
2. Session Management: You're correctly using the useUserSession composable to manage the user session. This is in line with the recommended approach.
3. Login Function: Your login function is structured correctly, making a POST request to /api/login and then refreshing the session on success.
4. Error Handling: You're catching errors, but you might want to provide more specific error messages to the user instead of just alerting the error object.
5. Navigation: After successful login, you're navigating to '/dashboard'. Ensure that this route exists and is protected for authenticated users only.
To address potential issues with loggedIn.value always being false, consider the following:
1. Verify that the refreshSession function is working as expected. You can add a console log right after calling it to check if the session state is updated:
2. If the session isn't refreshing properly, you might need to manually update the state. As suggested in the Stack Overflow Post > How do I access useState inside middleware in Nuxt 3?, you could try:
Add this after the successful login and before navigation.
3. Make sure your API is correctly setting the session cookie. In your API route, after successful authentication, you should have something like:
4. If you're still having issues, you might want to use the refreshCookie utility as mentioned in the Docs > Api > Utils > refreshCookie:
5. Lastly, ensure that your server-side authentication logic is correctly setting the session cookie. Check your server logs for any errors related to cookie setting or session management.
If you continue to face issues after implementing these suggestions, it would be helpful to see your server-side authentication code (like the /api/login endpoint) to provide more specific guidance.

@kapa.ai I have the log : "Logged in: false" and my api in a nestjs api. The code is : "@HttpCode(HttpStatus.OK)
@Post('login')
@Public()
signIn(@Body() authDto: AuthDto): Observable<{ access_token: string }> {
return this.authService.signIn(authDto.email, authDto.password).pipe(

return of(token);
}),
);
}"
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on the information you've provided and the knowledge sources available, it seems that there might be a disconnect between your NestJS API and your Nuxt frontend in terms of session management. Let's analyze the situation:
1. NestJS API: Your NestJS login endpoint is returning an access token, which is a common approach for JWT-based authentication. However, this doesn't automatically set up a session that Nuxt can recognize.
2. Nuxt Session: The
loggedIn: false log suggests that the Nuxt session is not being properly set after login. This is likely because the nuxt-auth-utils module expects a specific session setup, which your current API doesn't provide.
To resolve this issue, you need to align your NestJS API with what Nuxt expects for session management. Here are some steps you can take:
1. Modify your NestJS API:
Instead of just returning an access token, you should set a session cookie. You might need to use a library like cookie-session in NestJS to achieve this. Your login endpoint should set a secure, HTTP-only cookie with the session information.
2. Update your Nuxt login handler:
In your Nuxt login view, after receiving a successful response from the API, you need to ensure that the session is properly set. The Docs > Guide > Recipes > Sessions and Authentication > Login API Route shows an example of how this should be done on the Nuxt side:
3. Ensure cookie handling:
Make sure your Nuxt app is configured to send and receive cookies with your API. You might need to adjust your fetch options or Axios config (if you're using Axios) to include credentials.
4. Check CORS settings:
If your API and Nuxt app are on different domains, ensure that your CORS settings allow credentials and that the correct origin is set.
5. Verify environment variables:
Double-check that your NUXT_SESSION_PASSWORD is correctly set in your production environment, as mentioned in the Docs > Guide > Recipes > Sessions and Authentication > Cookie Encryption Key.
If you implement these changes and still face issues, you might need to dig deeper into how the session is being managed on both the NestJS and Nuxt sides. Consider using browser developer tools to inspect the cookies and network requests to ensure the session cookie is being set and sent correctly.
Remember, the nuxt-auth-utils module expects a specific session setup, so you might need to adjust your authentication flow to match what this module expects. If you continue to face difficulties, you might want to consider using a different authentication strategy that aligns better with your NestJS backend, or seek further assistance from the Nuxt and NestJS communities.

@HttpCode(HttpStatus.OK)
@Post('login')
@Public()
signIn(@Body() authDto: AuthDto): Observable<{ access_token: string }> {
return this.authService.signIn(authDto.email, authDto.password).pipe(
switchMap((token: { access_token: string }) => {

}),
);
}
@kapa.ai Ok I understand, so can you provide me the code to use my access_token ?
Let me check the knowledge base for you again. One moment! :books:
----------------------
Certainly! I can provide you with an example of how to use the
access_token returned by your NestJS API in your Nuxt application. This approach will differ slightly from the session-based authentication we discussed earlier, as we'll be using JWT (JSON Web Token) authentication instead.
Here's how you can modify your Nuxt code to use the access_token:
1. First, let's update your login function in the Nuxt login view:
2. Next, create a plugin to add the token to all API requests. Create a new file plugins/api.ts:
3. Update your useUserSession composable. Create a new file composables/useUserSession.ts:
4. In your nuxt.config.ts, make sure to register the API plugin:
This setup will:
- Store the access_token in a secure cookie after successful login
- Add the token to all API requests automatically
- Provide a useUserSession composable that manages the user's logged-in state and session data
Remember to adjust your server-side routes to validate the JWT token for protected routes. Also, ensure that your NestJS API is set up to validate JWT tokens in the Authorization header.
This approach aligns with the JWT authentication strategy your NestJS backend is using. However, keep in mind that storing JWTs in cookies can have security implications, so make sure to implement proper security measures like using HTTPS, setting secure and httpOnly flags on cookies, and implementing CSRF protection.
