Refactor Swagger Endpoint Validation and Implement Custom Options Handling #315
Conversation
…with service name for Consul and PollConsul types
…Points` method and commented the exception being thrown when Swagger endpoints are null. 2. Added MMLib.ServiceDiscovery.Consul project for Consul Auto discovery clients who don't use SwaggerEndpoints in their ocelot.json file 3. Updated `MMLib.SwaggerForOcelot` in `ServiceCollectionExtensions`: Modified `AddSwaggerForOcelot` method to include conditional logic for Consul integration. 4. ConsulSwaggerEndpointProvider added if type is Consul or PollConsul. It gets Endpoints from Consul
…Exception throwing block refactored using IEndPointValidator.cs 2. created custom OnChange instead of IOptionsMonitor.OnChange to monipulate with Options which added Programmatically and don't effect to config options. Both works well

3-5: Add meaningful documentation for the interface.The XML documentation comment for the interface is currently empty. Please add a description of the interface's purpose, any important details about its usage, and potentially an example if applicable. This will greatly improve the maintainability and usability of the code.
Here's a suggested structure for the documentation:
/// <summary> /// Provides a service for correcting Consul names. /// </summary> /// <remarks> /// This interface is used to standardize or modify names used in Consul operations, /// ensuring consistency and adherence to naming conventions. /// </remarks>
8-8: Add XML documentation for the CorrectConsulName method.The
CorrectConsulNamemethod is well-named and has a clear signature. However, it would benefit from XML documentation to provide more details about its purpose, parameters, and return value.Consider adding documentation like this:
/// <summary> /// Corrects the given Consul name according to predefined rules or conventions. /// </summary> /// <param name="name">The original Consul name to be corrected.</param> /// <returns>The corrected Consul name.</returns> string CorrectConsulName(string name);
1-9: Overall, good interface structure; documentation needs improvement.The
IConsulNameCorrectorServiceinterface is well-defined and follows .NET conventions. However, to improve code maintainability and usability, please add comprehensive XML documentation for both the interface and its method. This will provide clear guidance for developers implementing or using this interface in the future.src/MMLib.ServiceDiscovery.Consul/Services/Consul/IConsulConnectionService.cs (2)
3-7: Add a description to the interface's XML comment block.The XML comment block for the
IConsulConnectionServiceinterface is currently empty. Please add a description that explains the purpose of this interface and its role in managing Consul connections.Here's a suggested comment to add:
/// <summary> /// Defines a contract for services that manage connections to Consul. /// </summary>
8-11: Add a description to the Start() method's XML comment block.The XML comment block for the
Start()method is currently empty. Please add a description that explains the purpose of this method and its expected behavior.Here's a suggested comment to add:
/// <summary> /// Initiates the connection to the Consul service. /// </summary>src/MMLib.ServiceDiscovery.Consul/Services/Swagger/ISwaggerService.cs (3)
1-1: Remove unused import.The
Microsoft.OpenApi.Modelsnamespace is imported but not used in this file. Consider removing this import to keep the code clean and avoid potential confusion.-using Microsoft.OpenApi.Models;
5-8: Add meaningful XML comments for the interface.The XML comments for the
ISwaggerServiceinterface are currently empty. Consider adding a description of the interface's purpose and its role in the service discovery context. This will improve code documentation and make it easier for other developers to understand and use this interface.Example:
/// <summary> /// Defines a service for retrieving Swagger information in the context of service discovery. /// </summary> public interface ISwaggerService
15-16: Remove unnecessary blank line.There's an unnecessary blank line before the closing brace of the interface. Remove this line to adhere to the SA1508 style rule, which states that a closing brace should not be preceded by a blank line.

12-15: LGTM: Event declaration is appropriate. Consider enhancing XML documentation.The
OptionsChangedevent is well-named and its typeEventHandler<List<SwaggerEndPointOptions>>is suitable for its purpose. It allows for notifying subscribers about changes to multiple Swagger endpoint options simultaneously.Consider adding more detailed XML documentation for the event to describe its purpose and when it's triggered. For example:
/// <summary> /// Event triggered when the list of Swagger endpoint options changes. /// </summary>
7-9: Enhance XML documentation for better code understanding.The XML documentation comments for both the interface and the event are present but empty. To improve code documentation and maintainability, consider adding meaningful descriptions:
For the interface:
/// <summary> /// Defines a monitor for Swagger endpoints that notifies subscribers about changes in endpoint configurations. /// </summary>For the event (as mentioned in the previous comment):
/// <summary> /// Event triggered when the list of Swagger endpoint options changes. /// </summary>Also applies to: 12-14
src/MMLib.SwaggerForOcelot/Repositories/EndPointValidators/IEndPointValidator.cs (2)
15-15: LGTM: Method signature is well-defined. Consider returning validation results.The
Validatemethod signature is clear and usesIReadOnlyList<SwaggerEndPointOptions>, which is a good practice. However, consider returning a validation result instead of void. This could provide more flexibility in handling validation outcomes.You might want to consider changing the method signature to return a validation result:
- void Validate(IReadOnlyList<SwaggerEndPointOptions> endPoints); + ValidationResult Validate(IReadOnlyList<SwaggerEndPointOptions> endPoints);This would allow callers to handle validation failures more flexibly without relying solely on exceptions.
6-8: Add meaningful XML documentation comments.The XML documentation comments for both the interface and the
Validatemethod are present but empty. Please add meaningful documentation to improve code maintainability and usability.Here's a suggestion for the documentation:
/// <summary> /// Defines a contract for validating Swagger endpoints. /// </summary> public interface IEndPointValidator { /// <summary> /// Validates a list of Swagger endpoint options. /// </summary> /// <param name="endPoints">The list of Swagger endpoint options to validate.</param> /// <exception cref="ValidationException">Thrown when the endpoints are invalid.</exception> void Validate(IReadOnlyList<SwaggerEndPointOptions> endPoints); }Also applies to: 11-14
src/MMLib.ServiceDiscovery.Consul/Services/Consul/ConsulNameCorrectorService.cs (3)
3-6: Class declaration is correct, but XML documentation needs improvement.The class declaration follows proper naming conventions and correctly implements the
IConsulNameCorrectorServiceinterface. However, the XML documentation is empty and should be filled with a description of the class's purpose and functionality.Consider adding a description to the XML documentation, for example:
/// <summary> /// Provides functionality to correct Consul service names by removing specific prefixes. /// </summary>
8-16: Method implementation is correct, but XML documentation needs improvement.The
CorrectConsulNamemethod is well-implemented with proper null-handling. However, the XML documentation is incomplete and should be expanded to describe the method's purpose, parameters, and return value.Consider enhancing the XML documentation as follows:
/// <summary> /// Corrects the Consul service name by removing the "MS." prefix if present. /// </summary> /// <param name="name">The original Consul service name.</param> /// <returns>The corrected Consul service name, or null if the input is null.</returns>Additionally, consider adding a remark about the behavior when the input doesn't contain "MS.":
/// <remarks> /// If the input name doesn't contain "MS.", it will be returned unchanged. /// </remarks>
1-17: Overall, the implementation is sound, but documentation could be improved.The
ConsulNameCorrectorServiceclass and itsCorrectConsulNamemethod are well-implemented and follow good coding practices. The functionality aligns with the class's purpose of correcting Consul service names.To enhance the overall quality of the code:
- Improve XML documentation throughout the file as suggested in previous comments.
- Consider adding unit tests to verify the behavior of the
CorrectConsulNamemethod, including edge cases (e.g., null input, input without "MS." prefix).Would you like assistance in generating unit tests for this class?

6-8: Documentation needed: Add descriptive comments.The XML documentation comments for both the
ConsulEndPointValidatorclass and theValidatemethod are empty. Please add meaningful descriptions to improve code documentation. Include:
- A brief explanation of the class's purpose and its role in Consul endpoint validation.
- For the
Validatemethod, describe its functionality, the expected format of theendPointsparameter, and any side effects or exceptions it might throw.Example for the class:
/// <summary> /// Validates Swagger endpoints for Consul service discovery integration. /// </summary>Example for the method:
/// <summary> /// Validates the provided Swagger endpoints against Consul service registry. /// </summary> /// <param name="endPoints">A list of Swagger endpoints to validate.</param> /// <exception cref="ValidationException">Thrown when an endpoint fails validation.</exception>Also applies to: 11-14
src/MMLib.SwaggerForOcelot/Repositories/OptionsMonitor/IConsulEndpointOptionsMonitor.cs (3)
12-15: LGTM: Event declaration is appropriate. Consider enhancing the XML documentation.The
OptionsChangedevent is well-named and correctly typed. It effectively communicates when Swagger endpoint options have changed.Consider adding more detailed XML documentation for the event, explaining when it's triggered and what the event args represent. For example:
/// <summary> /// Event triggered when the list of SwaggerEndPointOptions changes. /// </summary> /// <remarks> /// The event provides the updated list of SwaggerEndPointOptions. /// </remarks> event EventHandler<List<SwaggerEndPointOptions>> OptionsChanged;
17-20: LGTM: Property declaration is clear. Consider using IReadOnlyList for better encapsulation.The
CurrentValueproperty is appropriately named and correctly typed. However, returning aList<T>might expose the internal collection to modifications.Consider using
IReadOnlyList<SwaggerEndPointOptions>instead ofList<SwaggerEndPointOptions>to prevent unintended modifications:IReadOnlyList<SwaggerEndPointOptions> CurrentValue { get; }This change would provide better encapsulation while still allowing enumeration and indexed access to the options.
7-9: Enhance XML documentation for better code understanding.While XML documentation tags are present, they lack content. Proper documentation is crucial for understanding the purpose and usage of the interface and its members.
Consider adding detailed XML documentation for the interface and its members. For example:
/// <summary> /// Monitors changes in Consul endpoint options for Swagger. /// </summary> /// <remarks> /// This interface provides mechanisms to track and respond to changes in SwaggerEndPointOptions, /// which may occur due to updates in Consul service discovery. /// </remarks> public interface IConsulEndpointOptionsMonitor { /// <summary> /// Event triggered when the list of SwaggerEndPointOptions changes. /// </summary> /// <remarks> /// Subscribers to this event will receive the updated list of SwaggerEndPointOptions. /// </remarks> event EventHandler<List<SwaggerEndPointOptions>> OptionsChanged; /// <summary> /// Gets the current list of SwaggerEndPointOptions. /// </summary> /// <remarks> /// This property provides read-only access to the most up-to-date list of SwaggerEndPointOptions. /// </remarks> List<SwaggerEndPointOptions> CurrentValue { get; } }Also applies to: 12-14, 17-19

7-11: Add documentation for the interface.The interface
IConsulServiceDiscoverylacks documentation. To improve code maintainability and assist developers who will implement or use this interface, please add a comprehensive XML documentation comment describing the interface's purpose, responsibilities, and any important notes about its usage.Here's a suggested documentation comment:
/// <summary> /// Defines methods for discovering Swagger endpoints using Consul service discovery. /// </summary> /// <remarks> /// This interface is used to retrieve Swagger endpoint options from Consul, /// either as a list of all available services or by a specific key. /// Implementations of this interface should handle the communication with Consul /// and return the appropriate SwaggerEndPointOptions. /// </remarks>
12-16: Add documentation for GetServicesAsync method.The
GetServicesAsyncmethod lacks documentation. To improve code maintainability and assist developers who will use this method, please add a comprehensive XML documentation comment describing the method's purpose, return value, and any important notes about its usage.Here's a suggested documentation comment:
/// <summary> /// Asynchronously retrieves all available Swagger endpoint options from Consul. /// </summary> /// <returns> /// A task that represents the asynchronous operation. The task result contains /// a list of SwaggerEndPointOptions representing all available Swagger endpoints. /// </returns> /// <remarks> /// This method queries Consul for all registered services that have Swagger endpoints /// and returns their configuration options. The returned list can be empty if no /// services with Swagger endpoints are found. /// </remarks>
18-23: Add documentation for GetByKeyAsync method.The
GetByKeyAsyncmethod lacks documentation. To improve code maintainability and assist developers who will use this method, please add a comprehensive XML documentation comment describing the method's purpose, parameter, return value, and any important notes about its usage.Here's a suggested documentation comment:
/// <summary> /// Asynchronously retrieves a specific Swagger endpoint option from Consul by its key. /// </summary> /// <param name="key">The unique identifier of the Swagger endpoint in Consul.</param> /// <returns> /// A task that represents the asynchronous operation. The task result contains /// a SwaggerEndPointOptions representing the Swagger endpoint for the specified key. /// </returns> /// <remarks> /// This method queries Consul for a specific service with the given key and returns /// its Swagger endpoint configuration options. If no service is found for the given key, /// the method may return null or throw an exception, depending on the implementation. /// </remarks>
10-24: LGTM: Well-designed interface with a suggestion for error handling.The
IConsulServiceDiscoveryinterface is well-designed and aligns with the PR objectives. It provides clear, asynchronous methods for retrieving Swagger endpoint options from Consul, supporting both bulk retrieval and specific key lookup. The design is concise and follows good practices for service discovery interfaces.As a minor suggestion, consider adding documentation about error handling, particularly for the
GetByKeyAsyncmethod. It would be helpful to specify whether the method throws an exception or returns null when a key is not found.src/MMLib.SwaggerForOcelot/Extensions/JsonExtensions.cs (2)
4-9: Add summaries for namespace and class.Consider adding meaningful summaries for the namespace and class to improve documentation. This will help other developers understand the purpose and usage of this extension class.
Here's a suggested improvement:
namespace MMLib.SwaggerForOcelot.Extensions; /// <summary> -/// +/// Provides extension methods for JSON-related operations. /// </summary> public static class JsonExtensions
11-17: Improve method documentation.The method lacks a proper summary and parameter descriptions. Adding these will enhance the usability of the extension method.
Here's a suggested improvement:
/// <summary> -/// +/// Attempts to parse a JSON string into a JObject. /// </summary> -/// <param name="obj"></param> -/// <param name="swaggerJson"></param> -/// <returns></returns> +/// <param name="swaggerJson">The JSON string to parse.</param> +/// <param name="jObj">When this method returns, contains the parsed JObject if parsing succeeded, or null if parsing failed.</param> +/// <returns>true if the JSON was successfully parsed; otherwise, false.</returns> public static bool TryParse(this string swaggerJson, out JObject jObj)src/MMLib.ServiceDiscovery.Consul/MMLib.ServiceDiscovery.Consul.csproj (1)
1-7: LGTM! Consider adding a LangVersion property.The project configuration looks good. Targeting both .NET 7.0 and 8.0 ensures broader compatibility. Enabling implicit usings and nullable reference types aligns with modern C# development practices.
Consider adding a
<LangVersion>latest</LangVersion>property to ensure you're always using the latest C# language features compatible with your target frameworks:<PropertyGroup> <TargetFrameworks>net7.0;net8.0</TargetFrameworks> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> + <LangVersion>latest</LangVersion> </PropertyGroup>src/MMLib.SwaggerForOcelot/Repositories/EndPointValidators/EndPointValidator.cs (2)
7-10: Add a description to the class documentation.The XML documentation comment for the
EndPointValidatorclass is currently empty. Please add a brief description of the class's purpose and functionality.Here's a suggested documentation:
/// <summary> /// Validates the provided Swagger endpoints to ensure they meet the required criteria. /// </summary>
12-16: Add XML documentation for the Validate method.The
Validatemethod is missing XML documentation. Please add a description of the method's purpose, parameters, and potential exceptions.Here's a suggested documentation:
/// <summary> /// Validates the provided Swagger endpoints. /// </summary> /// <param name="endPoints">The list of Swagger endpoints to validate.</param> /// <exception cref="InvalidOperationException">Thrown when the endpoints list is null or empty.</exception>demo/ConsulAutoDiscovery/ConsulApiGateway/Program.cs (4)
5-11: LGTM: Proper application setup with a suggestion for error handling.The application setup and configuration are well-structured, following best practices for .NET 6+ and Ocelot. The use of a separate
ocelot.jsonfile withreloadOnChange: trueis excellent for maintainability.Consider adding a try-catch block around the configuration loading to provide more informative error messages if the
ocelot.jsonfile is missing or malformed. This can help with troubleshooting during deployment or configuration updates.
13-17: LGTM: Proper service configuration with a suggestion for flexibility.The services are correctly configured, adding Ocelot with Consul integration and Swagger support. This setup provides a solid foundation for the API Gateway.
Consider extracting the service configuration into a separate extension method (e.g.,
AddApiGatewayServices) to improve readability and maintainability, especially if the service configuration grows more complex in the future. For example:public static class ServiceCollectionExtensions { public static IServiceCollection AddApiGatewayServices(this IServiceCollection services, IConfiguration configuration) { return services .AddOcelot(configuration) .AddConsul() .AddSwaggerForOcelot(configuration); } } // Usage in Program.cs builder.Services.AddApiGatewayServices(builder.Configuration);
19-22: LGTM: Correct middleware configuration with a suggestion for error handling.The application pipeline is configured correctly, with Swagger UI for Ocelot added before the Ocelot middleware. The use of
awaitwithUseOcelot()is appropriate.Consider adding error handling middleware to catch and log any unhandled exceptions in the Ocelot pipeline. This can help with debugging and improve the robustness of your API Gateway. For example:
app.UseExceptionHandler("/error"); app.UseSwaggerForOcelotUI(); await app.UseOcelot(); app.Map("/error", errorApp => { errorApp.Run(async context => { context.Response.StatusCode = 500; context.Response.ContentType = "application/json"; var error = context.Features.Get<IExceptionHandlerFeature>(); if (error != null) { var ex = error.Error; await context.Response.WriteAsync(new ErrorDto() { Code = context.Response.StatusCode, Message = "An unexpected error occurred." }.ToString()); } }); });
24-25: LGTM: Basic endpoint and application run configuration with suggestions for improvement.The root endpoint and application run configuration are set up correctly. The use of
WithOpenApi()is good for documentation.Consider the following improvements for better flexibility and configuration:
Use configuration for the port instead of hardcoding it:
var port = builder.Configuration.GetValue<int>("ApiGateway:Port", 7001); app.Run($"http://0.0.0.0:{port}");Enhance the root endpoint to provide useful information:
app.MapGet("/", () => new { Message = "Consul API Gateway", Version = "1.0", Timestamp = DateTime.UtcNow }).WithOpenApi();Add a health check endpoint for better monitoring:
app.MapHealthChecks("/health").WithOpenApi();These changes will make your application more configurable and provide better information for monitoring and debugging.
src/MMLib.ServiceDiscovery.Consul/DependencyInjection/ConfigureExtensions.cs (3)
1-5: Remove unused using statementThe
using Swashbuckle.AspNetCore.SwaggerUI;statement is not used in the current implementation. Consider removing it to keep the code clean.using Microsoft.AspNetCore.Builder; using Microsoft.Extensions.DependencyInjection; -using Swashbuckle.AspNetCore.SwaggerUI;
7-10: Add meaningful XML commentsThe XML comments for the class are currently empty. Please add meaningful descriptions to improve code documentation. For example:
/// <summary> /// Provides extension methods for configuring Swagger UI and Consul connection in an ASP.NET Core application. /// </summary>
30-36: Approved with suggestion for error handlingThe
ConfigureConsulConnectionmethod is well-implemented. It correctly retrieves theIConsulConnectionServiceand starts the connection if available. The use of the null-conditional operator is appropriate.To improve robustness, consider adding error handling:
public static IApplicationBuilder ConfigureConsulConnection(this IApplicationBuilder builder) { var consul = builder.ApplicationServices.GetService<IConsulConnectionService>(); if (consul == null) { // Log a warning or throw an exception // Example: throw new InvalidOperationException("IConsulConnectionService is not registered."); } else { try { consul.Start(); } catch (Exception ex) { // Log the exception or handle it appropriately // Example: logger.LogError(ex, "Failed to start Consul connection."); } } return builder; }This change would provide better feedback if the service is missing or fails to start.
src/MMLib.ServiceDiscovery.Consul/Services/Swagger/SwaggerService.cs (3)
11-14: Add a description to the class XML documentation comment.The XML documentation comment for the
SwaggerServiceclass is currently empty. Please add a meaningful description of the class's purpose and functionality to improve code documentation.
21-28: Add a description to the constructor XML documentation comment.The XML documentation comment for the constructor is currently empty. Please add a meaningful description of the constructor's purpose and its parameter to improve code documentation.
30-37: Add a description to theGetSwaggerInfo()method XML documentation comment.The XML documentation comment for the
GetSwaggerInfo()method is currently empty. Please add a meaningful description of the method's purpose and its return value to improve code documentation.src/MMLib.SwaggerForOcelot/Transformation/ISwaggerJsonTransformer.cs (1)
26-37: LGTM with a minor documentation improvement.The new
AddServiceNamePrefixToPathsmethod is well-defined and its purpose is clear. The documentation is comprehensive and explains the method's behavior, including edge cases.However, there's a minor inconsistency in the documentation:
The
versionparameter is included in the method signature but not documented. Consider adding a description for this parameter in the XML comments, explaining its purpose and usage.Here's a suggested addition to the documentation:
/// <param name="version">The version of the service or API to be included in the path prefix.</param>src/MMLib.SwaggerForOcelot/Repositories/EndPointProviders/SwaggerEndPointProvider.cs (1)
59-68: Approved: Concise syntax improvement with a minor suggestion.The refactoring of the
AddEndpointmethod improves code conciseness without altering its functionality. The use of an expression-bodied method and more compact object initialization aligns with modern C# practices.For consistency, consider using object initializer syntax for the
SwaggerEndPointConfigas well. Here's a suggested minor improvement:=> ret.Add($"/{key}", new SwaggerEndPointOptions() { Key = key, TransformByOcelotConfig = false, Config = new List<SwaggerEndPointConfig>() { - new SwaggerEndPointConfig() { Name = description, Version = key, Url = "" } + new SwaggerEndPointConfig { Name = description, Version = key, Url = "" } } });This change removes the unnecessary parentheses after
SwaggerEndPointConfig, making it consistent with theSwaggerEndPointOptionsinitialization.src/MMLib.SwaggerForOcelot/MMLib.SwaggerForOcelot.csproj (1)
34-34: Consider using more specific version ranges for OcelotThe changes to use wildcard versions (18., 19., 20.) for Ocelot across different .NET framework targets are generally good. This approach allows for automatic minor version updates, which can include bug fixes and non-breaking changes. However, it's worth considering using more specific version ranges (e.g., 18.0. or >= 18.0.0 and < 19.0.0) to have more control over updates and reduce the risk of unexpected breaking changes.
Would you like me to provide examples of more specific version ranges?

498-500: Clarify the purpose ofAddServiceNamePrefixToPathsmethodThe
AddServiceNamePrefixToPathsmethod has been added to theTestSwaggerJsonTransformerclass, but its implementation doesn't align with its name. It simply returns_transformedJsonwithout performing any transformation based on the input parameters.Consider the following options:
- If this is intentional for testing purposes, add a comment explaining why the method doesn't actually transform the input.
- If the method should perform a real transformation, implement the logic to add the service name prefix to the paths in the swagger JSON.
Example implementation for option 2:
public string AddServiceNamePrefixToPaths(string swaggerJson, SwaggerEndPointOptions serviceName, string version) { // Parse the swagger JSON var swagger = JObject.Parse(swaggerJson); // Add service name prefix to paths var paths = (JObject)swagger["paths"]; var newPaths = new JObject(); foreach (var path in paths) { var newPath = $"/{serviceName.Key}{path.Key}"; newPaths[newPath] = path.Value; } swagger["paths"] = newPaths; return swagger.ToString(); }This implementation would actually add the service name prefix to the paths in the swagger JSON, which aligns with the method name.

16-25: Provide meaningful XML documentation for private fieldsThe private fields
_optionsMonitorand_consulOptionsMonitorhave empty XML documentation comments. While it's not critical for private members, adding summaries can be beneficial for understanding the code, especially in complex classes.Consider adding brief descriptions:
/// <summary> -/// +/// Monitors the list of Swagger endpoint options from configuration. /// </summary> private readonly IOptionsMonitor<List<SwaggerEndPointOptions>> _optionsMonitor; /// <summary> -/// +/// Monitors the list of Swagger endpoint options from Consul. /// </summary> private readonly IConsulEndpointOptionsMonitor _consulOptionsMonitor;
31-43: Provide meaningful XML documentation for the constructorThe constructor lacks XML documentation. Describing the purpose of the constructor and its parameters enhances code clarity.

37-45: Consider adding logging for parsing and transformation failuresThe method returns the original
swaggerJsonin multiple failure cases, such as parsing errors or missing sections. Adding logging statements in these cases can aid in debugging by providing insights into why the transformation was not applied.Example of where logging could be added:

30-38: Provide meaningful XML documentation comments for public members.The XML documentation comments for the class, constructors, properties, and methods are currently empty. Adding descriptive summaries enhances code readability and aids other developers in understanding the purpose of each member.
For example, update the class summary:
/// <summary> -/// +/// Monitors changes in Consul service endpoints and raises events when changes occur. /// </summary> public class ConsulEndpointOptionsMonitor : IConsulEndpointOptionsMonitorSimilarly, provide summaries for other members:
/// <summary> -/// +/// Event triggered when the list of Swagger endpoint options changes. /// </summary> public event EventHandler<List<SwaggerEndPointOptions>> OptionsChanged; /// <summary> -/// +/// Gets the current list of Swagger endpoint options. /// </summary> public List<SwaggerEndPointOptions> CurrentValue { get; private set; } = new();
41-41: Make timer interval configurable for flexibility.The timer interval is hardcoded to 300 milliseconds. Making this value configurable allows for greater flexibility and easier adjustments without modifying the code.
Consider adding a configuration parameter or constant:
+ private const double DefaultTimerInterval = 300; public ConsulEndpointOptionsMonitor(IConsulServiceDiscovery service) { _service = service; - _timer = new Timer(300); + _timer = new Timer(DefaultTimerInterval); _timer.Elapsed += (s, e) => TimerElapsed(); _timer.Start(); }Alternatively, accept the interval as a parameter in the constructor.

7-7: Consul service discovery dependency includedThe addition of
using MMLib.ServiceDiscovery.Consul.DependencyInjection;integrates Consul for service discovery, which is appropriate given the objectives of enhancing options management and service registration.src/MMLib.ServiceDiscovery.Consul/Services/Consul/ConsulConnectionService.cs (1)
144-147: Validate health check configuration intervalsThe health check is configured with a
Timeoutof 5 seconds and anIntervalof 2 seconds. The interval should typically be larger than the timeout to prevent false positives in service health status. Review these settings to ensure they align with the intended monitoring strategy.src/MMLib.SwaggerForOcelot/DependencyInjection/ServiceCollectionExtensions.cs (1)
135-135:⚠️ Potential issueRemove unnecessary space in URI construction
There's an extra space at the beginning of the interpolated string when constructing the Consul address. This can lead to an
UriFormatExceptiondue to an invalid URI.Apply this diff to fix the issue:
-var consulAddress = new Uri($" {conf.Scheme}://{conf.Host}:{conf.Port}"); +var consulAddress = new Uri($"{conf.Scheme}://{conf.Host}:{conf.Port}");Likely invalid or redundant comment.

50-50: Confirm the null-conditional invocation of the event.The use of the null-conditional operator in:
OptionsChanged?.Invoke(this, options);is appropriate for event invocation when there may be no subscribers. Verify that this behavior aligns with the intended design, ensuring that it's acceptable if no handlers are attached to the event.

This pull request introduces key improvements and refactoring to enhance the functionality and maintainability of the SwaggerForOcelot library:
Refactor AddSwaggerEndPoints Validation
The AddSwaggerEndPoints method in BuilderExtensions.cs has been refactored to improve argument validation by leveraging a new IEndPointValidator interface. This change ensures a cleaner and more modular validation process for Swagger endpoints, reducing complexity within the method and making it more extendable.
Custom Options Change Handler
A custom change handler has been implemented to address a limitation in IOptionsMonitor.OnChange. Previously, OnChange only handled updates based on configuration file (JSON) changes and did not account for options added programmatically. The new custom handler now manages both configuration-based and programmatically added options, providing more flexibility and control over options management at runtime.
Both of these changes have been tested and are working well, providing better flexibility and robustness in handling Swagger endpoint registration and options management in Ocelot-based applications
