IL.InMemoryCacheProvider 1.3.0

InMemory Cache Provider

• Basic implementation of generic in-memory cache provider, based on Microsoft.Extensions.Caching.Memory.
• Comes with set of useful thread safe extensions to get objects from cache or add them with factory.
• Introduces several not supported by default methods, like IEnumerable<string> GetAllKeys() or void DeleteAll().
• Supports tags on cache entries and eviction by tag.

Usage sample:

Register in DI with any container of your preference. Microsoft.Extensions.DependencyInjection will be used in this sample.

services.AddSingleton<ICacheProvider, InMemoryCacheProvider>();

class Test(ICacheProvider cacheProvider)
{

  void Foo(CancellationToken cancellationToken = default)
  {
    var cacheKey = "test";
    var cacheTags = ["test1", "test2"];
    var valueFromCache = cacheProvider.GetOrAdd(cacheKey,
                CacheValueFactory,
                tags: cacheTags,
                cacheCreationCondition: s => !string.IsNullOrEmpty(s),
                expirationOptions: new ExpirationOptions
                {
                    AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(1),
                    AbsoluteExpiration = DateTimeOffset.Now.AddMinutes(10),
                    SlidingExpiration = TimeSpan.FromSeconds(30)
                },
                cancellationToken: cancellationToken);
  }

  private string CacheValueFactory() => return "test value";

}
