10-14: Consider adding validation and documentation.

A few suggestions to improve the robustness of this class:

  1. Add XML documentation to describe the purpose of the class and its properties
  2. Consider adding validation to ensure Id is not Guid.Empty after initialization

Here's a suggested improvement:

+ /// <summary>
+ /// Represents a session state for Fusion authentication.
+ /// </summary>
 public partial class FusionSession
 {
+    /// <summary>
+    /// Gets or sets the unique identifier for the session.
+    /// </summary>
     [Id(0)] public required Guid Id { get; set; } = Guid.Empty;
 
+    /// <summary>
+    /// Gets or sets whether the session is authorized.
+    /// </summary>
     [Id(1)] public required bool IsAuthorized { get; set; }
 }

10-14: Consider implementing immutability for security.

Since this class is used for session management and authorization, consider:

  1. Making properties immutable after initialization
  2. Implementing proper access control on setters
  3. Adding audit logging for state changes

Here's a suggested approach:

 public partial class FusionSession
 {
-    [Id(0)] public required Guid Id { get; set; } = Guid.Empty;
-    [Id(1)] public required bool IsAuthorized { get; set; }
+    [Id(0)] public required Guid Id { get; init; } = Guid.Empty;
+    [Id(1)] private bool isAuthorized;
+    
+    [Id(1)]
+    public bool IsAuthorized
+    {
+        get => isAuthorized;
+        set
+        {
+            // Add audit logging here
+            isAuthorized = value;
+        }
+    }

Documentation needed for browser launch settings

The change to disable automatic browser launch ("launchBrowser": false) in the launch settings is not documented anywhere in the repository. Since this affects the local development workflow, especially for authentication testing, it should be documented in a README.md or similar guide.

  • Create a README.md file in the repository root
  • Document the manual steps needed to test the API and authentication flows
  • Explain why automatic browser launch is disabled by default
🔗 Analysis chain

Line range hint 1-41: Consider documenting this change in README or contributing guidelines.

Since this changes the default developer experience, it would be helpful to document why browsers won't auto-launch and how developers should test the authentication flows.


Let me check if there are any documentation files in other common locations.

Line range hint 18-47: Consider adding integration tests and deployment documentation.

This PR introduces significant authentication changes with multiple components:

  1. JWT authentication
  2. RPC authorization middleware
  3. WebSocket communication
  4. Service context management

To ensure reliability:

  • Add integration tests covering the authentication flow
  • Document the JWT configuration requirements for different environments
  • Include WebSocket endpoint security considerations in deployment docs

35-36: Confirm necessity of [Alias("AuthorizeAsync")] attribute

Applying [Alias("AuthorizeAsync")] to the AuthorizeAsync method may be redundant if the method name hasn't changed. Ensure that this attribute is necessary for your application's serialization or versioning requirements.

If the attribute is not required, consider removing it to simplify the code:

-    [Alias("AuthorizeAsync")]
     ValueTask<bool> AuthorizeAsync(string token);

38-39: Confirm necessity of [Alias("GetState")] attribute

Similar to the previous comment, verify if the [Alias("GetState")] attribute is needed for the GetState method. If not required, removing it can reduce complexity.

Consider this change:

-    [Alias("GetState")]
     ValueTask<FusionSession> GetState();
src/Argon.Api/Features/Jwt/JwtOptions.cs (1)

15-15: Address the TODO: Use a certificate for signing in production

The comment indicates the need to replace the symmetric key with a certificate in the production environment. Using asymmetric keys enhances security by safeguarding the private key and facilitating key rotation without downtime.

Would you like assistance in implementing certificate-based signing for JWT tokens?

1-5: LGTM!

The namespace structure and imports are well-organized and follow C# conventions.


6-9: Verify the necessity of multiple serialization attributes.

The class uses three different serialization approaches. While each serves a purpose, please verify if all are required:

  • [GenerateSerializer] for Orleans
  • [Serializable] for .NET
  • [MemoryPackable] for MemoryPack
✅ Verification successful

Let me gather more information about the usage of these serialization attributes in the codebase.


Based on the gathered information, I can now provide the final response:

Multiple serialization attributes are correctly used and necessary

The combination of serialization attributes is a consistent pattern across all persistence state classes in the codebase and serves specific purposes in the Orleans-based architecture:

  • [GenerateSerializer] is required for Orleans serialization (Microsoft.Orleans.Sdk package)
  • [MemoryPackable] is used for high-performance serialization (MemoryPack package is referenced and used project-wide)
  • [Serializable] is needed for .NET serialization compatibility with Orleans
  • [Alias] provides consistent type mapping across the Orleans cluster

15-15: LGTM! Consistent browser launch settings across profiles.

The change to disable automatic browser launch across all profiles is appropriate for an authentication-focused PR, as it allows for more controlled testing of auth flows.

Also applies to: 25-25, 34-34

src/Argon.Api/Program.cs (3)

1-9: LGTM! Import statements are properly organized.

The new imports are relevant to the JWT authentication and RPC features being added.


27-33: Verify authorization middleware sequence.

The FusionAuthorizationMiddleware is added to the RPC pipeline, but we should ensure it runs after authentication.

Let's check the middleware implementation:

#!/bin/bash
# Description: Verify authorization middleware implementation
# Look for proper authentication checks in the middleware

# Check FusionAuthorizationMiddleware implementation
ast-grep --pattern 'class FusionAuthorizationMiddleware {
  $$$
}'

# Look for authentication checks
rg "IAuthenticationService|AuthenticateAsync" --type cs

43-44: Verify secure WebSocket configuration.

WebSocket support is enabled for RPC communication. Ensure secure WebSocket (wss://) is enforced in production.

Let's check the WebSocket security configuration:

✅ Verification successful

WebSocket security is properly configured

The application has appropriate security measures in place:

  • HTTPS redirection is enforced via UseHttpsRedirection()
  • Authentication and authorization are properly configured before WebSocket middleware
  • WebSocket setup follows the secure middleware pipeline order

This ensures WebSocket connections will be upgraded only over HTTPS (WSS), providing secure communication.

15-19: LGTM! MessagePipe configuration is correct.

The analyzer is properly configured with appropriate asset inclusions.


52-54: LGTM! Good feature organization.

The addition of a dedicated JWT feature folder follows good organizational practices.


20-38: Verify package version compatibility.

The package versions look consistent within families (Orleans, EF Core). However, let's verify there are no potential conflicts.

#!/bin/bash
# Check for potential package conflicts or inconsistencies
rg -g "*.csproj" "PackageReference.*Version" | sort | uniq -c | sort -nr

8-8: LGTM! Ensure secrets are properly managed.

The addition of UserSecretsId is appropriate for managing sensitive JWT configuration.

Let's verify if the secrets are properly configured:

✅ Verification successful

Let me verify if there are any secrets configuration files or documentation in the repository.


Secrets configuration is properly set up and follows best practices

The codebase shows a well-structured JWT configuration setup:

  • JWT settings are properly externalized in appsettings.json files
  • Sensitive values like JWT key are configured through user secrets (via the UserSecretsId)
  • JWT configuration is properly injected via environment variables in AppHost
  • The implementation follows security best practices with proper token validation

src/Argon.Api/Grains/FusionGrain.cs (2)

7-10: ⚠️ Potential issue

Fix syntax error in class declaration: Invalid constructor syntax

The class FusionGrain uses an invalid syntax for constructor parameters in its declaration. In C#, classes do not support primary constructors (parameters after the class name). Instead, you should define a constructor inside the class and initialize any dependencies there.

Apply this diff to correct the class declaration and constructor:

-public class FusionGrain(
-    [PersistentState("sessions", "OrleansStorage")]
-    IPersistentState<FusionSession> sessionStorage,
-    TokenValidationParameters JwtParameters) : Grain, IFusionSession
-{
+public class FusionGrain : Grain, IFusionSession
+{
+    private readonly IPersistentState<FusionSession> _sessionStorage;
+    private readonly TokenValidationParameters _jwtParameters;
+
+    public FusionGrain(
+        [PersistentState("sessions", "OrleansStorage")] IPersistentState<FusionSession> sessionStorage,
+        TokenValidationParameters jwtParameters)
+    {
+        _sessionStorage = sessionStorage;
+        _jwtParameters = jwtParameters;
+    }

Likely invalid or redundant comment.


33-40: Verify the usage of [Alias] attributes in the interface

The [Alias] attribute applied to the interface methods may not have the intended effect. In Orleans, method aliases are typically used for versioning and interoperability, but they need to be correctly configured.

Run the following script to check if the [Alias] attribute is properly defined and used:

✅ Verification successful

Let me verify if the Orleans.Core package is properly referenced and if the Alias attribute is correctly imported.


Let me check for the specific Orleans namespace that contains the Alias attribute and its usage pattern in the codebase.


Let me check for the actual implementation of the FusionGrain and its interface to verify the Alias attribute usage pattern.


Based on the gathered evidence, I can now provide a final response:

The [Alias] attribute usage in IFusionSession is consistent with Orleans patterns

The usage of [Alias] attributes in the IFusionSession interface follows the same pattern as seen in other Orleans grain interfaces in the codebase (e.g., IServerManager, IUserManager, IChannelManager). The attribute is consistently used for method naming across the entire codebase, and the implementation in FusionGrain correctly implements the interface with these aliased methods.

💡 Codebase verification

Security concern: JWT implementation needs improvements

The JWT configuration has several security considerations that need to be addressed:

  • There's a TODO comment indicating temporary use of a string key instead of certificates: // TODO use cert in production
  • The JWT configuration uses a symmetric key with HS256 algorithm, which may not be the best choice for all scenarios
  • The token validation parameters are properly configured with all necessary validations enabled, but the key management needs improvement
  • Custom header x-argon-token is used instead of the standard Authorization: Bearer header

Recommendations:

  • Replace the symmetric key with asymmetric keys (certificates) as noted in the TODO
  • Consider using RS256 instead of HS256 for better security in distributed systems
  • Implement proper key rotation mechanisms
  • Use standard Authorization header instead of custom header unless there's a specific requirement

🛠️ Refactor suggestion

Optimize state retrieval in GetState

In the GetState method, you are calling ReadStateAsync() every time the method is invoked. If the state is already loaded and hasn't changed, this may be unnecessary and could introduce latency.

Consider checking if the state is already loaded before reading it again:

 public async ValueTask<FusionSession> GetState()
 {
-    await sessionStorage.ReadStateAsync();
+    if (!_sessionStorage.RecordExists)
+    {
+        await _sessionStorage.ReadStateAsync();
+    }
     return _sessionStorage.State;
 }

This change checks if the state exists before reading it, which can improve performance by avoiding unnecessary I/O operations.

⚠️ Potential issue

Handle invalid GUIDs when parsing JWT ID

When converting jwt.Id to a Guid, using Guid.Parse can throw an exception if the Id claim is not a valid GUID string. To prevent this, use Guid.TryParse and handle the scenario where parsing fails.

Apply this diff to safely parse the JWT ID:

-    sessionStorage.State.Id = Guid.Parse(jwt.Id);
+    if (Guid.TryParse(jwt.Id, out var sessionId))
+    {
+        _sessionStorage.State.Id = sessionId;

⚠️ Potential issue

Add exception handling in AuthorizeAsync to handle token validation errors

In the AuthorizeAsync method, the call to ValidateToken can throw exceptions (e.g., SecurityTokenException, ArgumentException) if the token is invalid or malformed. It's important to handle these exceptions to prevent the grain from crashing and to provide a proper response when token validation fails.

Consider wrapping the token validation in a try-catch block and returning false if validation fails:

 public async ValueTask<bool> AuthorizeAsync(string token)
 {
     var tokenHandler = new JwtSecurityTokenHandler();
-    tokenHandler.ValidateToken(token, JwtParameters, out SecurityToken validatedToken);
+    SecurityToken validatedToken;

     var jwt = (JwtSecurityToken)validatedToken;
-    sessionStorage.State.Id = Guid.Parse(jwt.Id);
-    sessionStorage.State.IsAuthorized = true;
-    await sessionStorage.WriteStateAsync();
+    if (Guid.TryParse(jwt.Id, out var sessionId))
+    {
+        _sessionStorage.State.Id = sessionId;
+        _sessionStorage.State.IsAuthorized = true;
+        await _sessionStorage.WriteStateAsync();
+        return true;

+    else
+    {
+        // Invalid GUID in JWT ID
+        return false;
+    }
-    return true;
 }

This change also incorporates safe parsing of jwt.Id using Guid.TryParse to handle cases where the Id claim might not be a valid GUID.

⚠️ Potential issue

Handle exceptions from grain.GetState()

Ensure that exceptions thrown by grain.GetState() are appropriately handled to maintain application stability.

Consider adding exception handling:

try
{
    return await grain.GetState();
}
catch (Exception ex)
{
    // Handle exception, e.g., log the error and throw a custom exception
    throw new InvalidOperationException("Failed to retrieve session state.", ex);
}

🛠️ Refactor suggestion

Use Any() method for checking attribute existence

Improve readability by using Any() instead of comparing Count != 0.

Apply this diff to refactor the code:

-var existAttribute = call.MethodDef.Method.GetAttributes<AuthorizeAttribute>(true, true).Count != 0;
+var authorizeAttributeExists = call.MethodDef.Method.GetAttributes<AuthorizeAttribute>(true, true).Any();

⚠️ Potential issue

Fix the parameter assignment order in the Deconstruct method

The assignments in the Deconstruct method do not match the parameter order, which can lead to incorrect values when deconstructing the JwtOptions instance. Specifically, issuer and audience are assigned incorrectly.

Apply this diff to correct the assignment order:

 public void Deconstruct(out string issuer, out string audience, out string key)

⚠️ Potential issue

Avoid setting the response status code in the OnMessageReceived event

Modifying the response status code within the OnMessageReceived event is unnecessary and can interfere with the authentication middleware's default behavior. The middleware will automatically handle unauthorized responses when authentication fails.

Apply this diff to remove the manual status code assignment:

 OnMessageReceived = ctx =>
 {
     if (ctx.Request.Headers.TryGetValue("x-argon-token", out var value))
     {
         ctx.Token = value;
         return Task.CompletedTask;

🛠️ Refactor suggestion

Consider supporting the standard Authorization header alongside the custom header

To improve interoperability and adhere to HTTP standards, consider extracting the token from the standard Authorization header in addition to the custom x-argon-token header.

Update the OnMessageReceived event to check both headers:

 OnMessageReceived = ctx =>
 {
+    if (ctx.Request.Headers.TryGetValue("Authorization", out var authHeader))
+    {
+        var token = authHeader.ToString().Split(' ').Last();
+        ctx.Token = token;
+        return Task.CompletedTask;
+    }

     if (ctx.Request.Headers.TryGetValue("x-argon-token", out var value))
     {
         ctx.Token = value;
         return Task.CompletedTask;
     }

     return Task.CompletedTask;
