Shared Library

Redis Services

Provides various Redis functionalities for microservices.

Caching Functionality

The ICacheService interface provides caching operations:

public interface ICacheService
{
    Task<T?> GetAsync<T>(string key);
    Task<bool> SetAsync<T>(string key, T value, TimeSpan? expiration = null);
    Task<bool> RemoveAsync(string key);
    Task<bool> ExistsAsync(string key);
    Task<bool> SetExpirationAsync(string key, TimeSpan expiration);
    Task<TimeSpan?> GetTimeToLiveAsync(string key);
}

Queue Functionality

The IQueueService interface provides queue operations:

public interface IQueueService
{
    Task EnqueueAsync<T>(string queueName, T item);
    Task<T?> DequeueAsync<T>(string queueName);
    Task<long> GetLengthAsync(string queueName);
    Task<T?> PeekAsync<T>(string queueName);
    Task ClearAsync(string queueName);
}

Dependency Injection Setup

1. Configuration

Add Redis configuration to your appsettings.json:

{
  "Redis": {
    "ConnectionString": "localhost:6379",
    "DatabaseId": 0,
    "ConnectTimeout": 60000,
    "SyncTimeout": 60000,
    "ConnectRetry": 3,
    "ReconnectRetryPolicy": 3
  }
}

2. Service Registration

In your Program.cs or Startup.cs:

using SharedLibrary.Cache.ServiceCollectionExtensions;

// Add Redis connection
builder.Services.AddRedis(configuration);

// Add Redis cache service
builder.Services.AddRedisCache(configuration);

// Add Redis queue service
builder.Services.AddRedisQueue(configuration);
