-# EonaCat.gRPC
+# 🚀 EonaCat.gRPC
 
-EonaCat.gRPC
+A modern .NET 10 gRPC solution built with:

+
+# Requirements
+
+* .NET 10 SDK
+* SQL Server
+* Visual Studio 2022+ or Rider
+
+# Installation
+
+Clone the repository:
+
+```bash
+git clone https://github.com/your-org/EonaCat.gRPC.git
+cd EonaCat.gRPC
+```
+
+Restore packages:
+
+```bash
+dotnet restore
+```
+
+Build:
+
+```bash
+dotnet build
+```
+
+Run API:
+
+```bash
+dotnet run --project EonaCat.gRPC.Api
+```
+
+# Configuration
+
+## appsettings.json
+
+```json
+{
+  "ConnectionStrings": {
+    "DefaultConnection": "Server=.;Database=GrpcDb;Trusted_Connection=True;"
+  },
+
+  "Jwt": {
+    "Secret": "your-super-secret-key"
+  }
+}
+```
+
+# Dependency Injection
+
+Services are registered automatically during startup.
+
+```csharp
+builder.Services.AddTransient<IUserService, UserService>();
+
+builder.Services.AddScoped<IUserRepository, UserRepository>();
+
+builder.Services.AddScoped(typeof(IBaseRepository<>),
+                          typeof(BaseRepository<>));
+```
+
+# gRPC Service Registration
+
+```csharp
+builder.Services.AddGrpc(options =>
+{
+    options.Interceptors.Add<LoggerInterceptor>();
+    options.Interceptors.Add<ExceptionInterceptor>();
+});
+
+builder.Services.AddCodeFirstGrpc();
+builder.Services.AddGrpcReflection();
+builder.Services.AddGrpcSwagger();
+builder.Services.AddGrpc().AddJsonTranscoding();
+```
+
+# User Service Contract
+
+```csharp
+[ServiceContract]
+public interface IProtoUserService
+{
+    ValueTask<BaseResponse<string>> Create(
+        UserCreateRequest request);
+
+    Task<BaseResponse<UserResponse?>> GetByIdAsync(
+        string id);
+
+    Task<BaseResponse<List<UserResponse>?>> GetAsync();
+}
+```
+
+# Creating a User
+
+## Request
+
+```csharp
+var request = new UserCreateRequest
+{
+    FirstName = "John",
+    LastName = "Doe",
+    Email = "john@example.com"
+};
+```
+
+## Client Call
+
+```csharp
+var response = await client.Create(request);
+
+Console.WriteLine(response.Data);
+```
+
+# Getting a User
+
+```csharp
+var response = await client.GetByIdAsync("1");
+
+Console.WriteLine(response.Data?.FirstName);
+```
+
+# Getting All Users
+
+```csharp
+var users = await client.GetAsync();
+
+foreach (var user in users.Data)
+{
+    Console.WriteLine(user.Email);
+}
+```
+
+# Client Example
+
+```csharp
+using Grpc.Net.Client;
+
+using var channel =
+    GrpcChannel.ForAddress("http://localhost:5227");
+
+var client =
+    channel.CreateGrpcService<IProtoUserService>();
+
+var users = await client.GetAsync();
+```
+
+# JSON Transcoding
+
+Because JSON Transcoding is enabled, services can be accessed through standard HTTP requests.
+
+Example:
+
+```http
+GET /users
+```
+
+```http
+GET /users/1
+```
+
+This allows browsers, Postman, mobile apps, and JavaScript applications to consume your gRPC services.
+
+# Authentication
+
+JWT Authentication is configured using:
+
+```csharp
+builder.Services
+    .AddAuthentication()
+    .AddJwtBearer(options =>
+    {
+        options.TokenValidationParameters =
+            new TokenValidationParameters
+            {
+                ValidateIssuerSigningKey = true
+            };
+    });
+```
+
+Add your token:
+
+```http
+Authorization: Bearer YOUR_TOKEN
+```
+
+# Logging
+
+EonaCat.LogStack is integrated throughout the solution.
+
+```csharp
+builder.AddEonaCatLogging();
+```
+
+Client logging:
+
+```csharp
+LoggerFactory.Create(builder =>
+{
+    builder.AddEonaCatLogging();
+    builder.SetMinimumLevel(LogLevel.Debug);
+});
+```
+
+# Interceptors
+
+## Logging Interceptor
+
+```csharp
+options.Interceptors.Add<LoggerInterceptor>();
+```
+
+Provides:
+
+* Request logging
+* Response logging
+* Execution timing
+* Diagnostics
+
+## Exception Interceptor
+
+```csharp
+options.Interceptors.Add<ExceptionInterceptor>();
+```
+
+Provides:
+
+* Global exception handling
+* Consistent error responses
+* Centralized logging
+
+# Swagger Support
+
+Swagger UI is automatically enabled.
+
+Navigate to:
+
+```text
+https://localhost:<port>/swagger
+```
+
+You can:
+
+* Browse endpoints
+* Test requests
+* Inspect schemas
+* View authentication requirements
+
+# Reflection Support
+
+Reflection is enabled for tools such as:
+
+* grpcurl
+* Postman
+* BloomRPC
+* Kreya
+
+```csharp
+app.MapGrpcReflectionService();
+```
+
+# Example grpcurl Commands
+
+List services:
+
+```bash
+grpcurl localhost:5227 list
+```
+
+Describe service:
+
+```bash
+grpcurl localhost:5227 describe IProtoUserService
+```
+
+Call endpoint:
+
+```bash
+grpcurl \
+-d '{"id":"1"}' \
+localhost:5227 \
+IProtoUserService/GetByIdAsync
+```
