# Redis

Redis cache provides own configuration properties. For configuration details please [visit](https://docs.eiffel.dev/features/caching/api/rediscacheoptions).

You can configure values from appsettings.json file

```json
{
    "Caching": {
        "Source": "Redis",
        "Redis": {
            "Hosts": [
                "localhost:6379",
            ],
            "Username": "admin",
            "Password": "your+str0ng_Password!"
        }
    }
}
```

If you need to advanced configuration or configure cache service without appsettings.json file. You can use extension method.\
\
AddCaching method initally read values from appsettings.json file afterwards applies configuration from action method.

```csharp
// Program.cs (.NET5 and above)
public static async Task Main(string[] args)
{
    var builder = WebApplication.CreateBuilder(args);
    
    // Add with configuration instance
    var cacheOptions = new RedisCacheOptions();
    cacheOptions.Hosts = new [] { "localhost:6379" };
    cacheOptions.UserName = "admin";
    cacheOptions.Password = "your+str0ng_Password!";
    builder.AddCaching(x => x.Redis(cacheOptions));

    // Add with inline action method
    builder.AddCaching(x => x.Redis(x => x.BacklogPolicy = StackExchange.Redis.BacklogPolicy.FailFast));
 
    var app = builder.Build();
    app.Run();
}
```
