Installation

Install via nuget

PM> Install-Package Carter.Cache

This library depends on Carter to properly work, you can install Carter using the following command:

PM> Install-Package Carter

Sample usage

  1. Add carter caching to your Program.cs:
var builder = WebApplication.CreateBuilder(args);

//The rest of your Program.cs configuration ....

//It is recommended to always provide a caching max size limit
builder.Services.AddCarterCaching(new CachingOption(2048));
builder.Services.AddCarter();
  1. Define a Configuration usage
var app = builder.Build();

//The rest of your configuration usage ....

app.UseCarterCaching();
app.MapCarter();

app.Run();

  1. Add the Cacheable clause to your module:
    public class HomeModule : ICarterModule
    {
        public void AddRoutes(IEndpointRouteBuilder app)
        {
            app.MapGet("/", (HttpContext ctx) =>
            {
                ctx.AsCacheable(10); //In Seconds

                ctx.Response.StatusCode = 200;
                return ctx.Response.WriteAsync("Hello world");
            });
        }
    }

The default configuration does use the Microsoft.Extensions.Caching.Memory library as a default caching mechanism. Note: By default memory caching can put lots of pressure on the memory of your system, please refer to the following microsoft in-memory cache docs for basics on usage.

Customization

You can easily define a custom Store by implementing the ICacheStore interface with the following signature:

    public interface ICacheStore
    {
        bool TryGetValue(string key, out CachedResponse cachedResponse);

        void Set(string key, CachedResponse response, TimeSpan expiration);

        void Remove(string key);
    }

Also a custom Key can be easily defined by implementing the ICacheKey interface:

    public interface ICacheKey
    {
        string Get(HttpRequest request);
    }

Redis store

A redis store which includes the dependency on StackExchange.Redis and can be used as a replacement of the memory store.

Firstly, install the library using .net cli dotnet add package Carter.Cache.Redis or using Package Manager Install-Package Carter.Cache.Redis. The usage requires the following configurations on the Startup.cs file:

//The rest of your Program.cs ....

builder.Services.AddSingleton<ICacheStore>(new RedisStore("127.0.0.1:6379"));
builder.Services.AddSingleton(provider => new CachingOption()
{
    Store = provider.GetRequiredService<ICacheStore>()
});

IServiceProvider serviceProvider = builder.Services.BuildServiceProvider();

builder.Services.AddCarterCaching(serviceProvider.GetRequiredService<CachingOption>());
builder.Services.AddCarter();

As part of the redis definition, you can optionally provide a json serializer definition to be used for the serialization of the cached response. This uses the System.Text.Json library.

//The rest of your Program.cs ....

var jsonOptions = new System.Text.Json.JsonSerializerOptions() { AllowTrailingCommas = true };

builder.Services.AddSingleton<ICacheStore>(new RedisStore("127.0.0.1:6379", jsonOptions));
builder.Services.AddSingleton(provider => new CachingOption()
{
    Store = provider.GetRequiredService<ICacheStore>()
});

IServiceProvider serviceProvider = builder.Services.BuildServiceProvider();

builder.Services.AddCarterCaching(serviceProvider.GetRequiredService<CachingOption>());
builder.Services.AddCarter();

Memcached store

Alternatively, a memcached store can also be included as an alternatively, using a dependency on the library EnyimMemcachedCore.

To install, using .net cli dotnet add package Carter.Cache.Memcached or using Package Manager Install-Package Carter.Cache.Memcached. The usage requires the following reconfigurations on the ConfigureServices method of Startup:

//The rest of your Program.cs ....

//Point to the server / port desired
builder.Services.AddEnyimMemcached(options => options.AddServer("127.0.0.1", 11211));

//Resolve the IMemcachedClient dependency using EnyimMemcached
builder.Services.AddSingleton<ICacheStore>(provider => new MemcachedStore(provider.GetRequiredService<IMemcachedClient>()));

//Define Caching options using the store configured
builder.Services.AddSingleton(provider => new CachingOption()
{
    Store = provider.GetRequiredService<ICacheStore>()
});

IServiceProvider serviceProvider = services.BuildServiceProvider();

//Pass it as a dependency to the add
services.AddCarterCaching(serviceProvider.GetRequiredService<CachingOption>());
