Welcome to PretWorks.Helpers.Cache

Easy to use helper for your basic caching needs.
It’s a wrapper around the IMemoryCache that will help with the basic tasks of null checking.

Basic installation

Getting the package:

Install-Package PretWorks.Helpers.Cache

Setup:

Register the cache helper in startup.cs

services.AddTransient(typeof(ICachehelper), typeof(InMemoryCacheHelper));

Register the cache provider in startup.cs

(for example the MemoryCache from the nuget package Microsoft.Extensions.Caching.Memory)

services.AddMemoryCache();

Basic usage:

You can now inject the ICacheService into your code and use it for example:

 public class TestService
 { 
    private readonly ICachehelper _cachehelper;
    private readonly IHttpClientFactory _clientFactory;
    public TestService(ICachehelper cachehelper, IHttpClientFactory clientFactory)
    {
        _cachehelper = cachehelper;
        _clientFactory = clientFactory;
    }
    private async Task<string> GetAsync()
    {
        return await _cachehelper.GetOrAddAsync(
        "MyCacheKey",  // Cache Key
        async () =>
        {
            var client = _clientFactory.CreateClient("Get");
            var response = await client.GetAsync(new Uri("https://www.google.com"));
            if (response.IsSuccessStatusCode)
            {
                return await response.Content.ReadAsStringAsync();
            }
            return null;
        }, // Call to get data
        300 // Time in seconds to cache
        );
    }
}
