SqliteCache for ASP.NET Core

SqliteCache is a persistent cache implementing IDistributedCache for ASP.NET Core projects.

SqliteCache uses a locally stored SQLite database file (taking advantage of SQLite's battle-tested safe multi-threaded access features) to replicate persistent caching, allowing developers to mimic the behavior of staging or production targets without all the overhead or hassle of a traditional IDistributedCache implementation. You can read more about its design and inspiration in the official release post on the NeoSmart blog.

Why NeoSmart.Caching.Sqlite?

The currently available options for caching in ASP.NET Core projects are either all ephemeral in-memory cache offerings (IMemoryCache and co.) -- aka non-persistent -- or else have a whole slew of dependencies and requirements that require at the very least administrator privileges and background services hogging up system resources and needing updates and maintenance to requiring multiple machines and a persistent network configuration.

  • NeoSmart.Caching.Sqlite has no dependencies on background services that hog system resources and need to be updated or maintained (cough cough NCache cough cough)
  • NeoSmart.Caching.Sqlite is fully cross-platform and runs the same on your Windows PC or your colleagues' Linux, FreeBSD, and macOS workstations (unlike, say, Redis)
  • NeoSmart.Caching.Sqlite doesn't need administrator privileges to install - or even any installation for that matter (SQL Express LocalDB, this one is aimed at you)
  • NeoSmart.Caching.Sqlite is a fully contained IDistributedCache offering that is installed and updated alongside the rest of your packages via NuGet, Paket, or whatever other option you're already using to manage your dependencies.

Installation

SqliteCache is available via the NuGet, and can be installed in the Package Manager Console as follows:

Install-Package NeoSmart.Caching.Sqlite

Usage

Using SqliteCache is straight-forward, and should be extremely familiar for anyone that's configured an ASP.NET Core application before. Starting by adding a namespace import using NeoSmart.Caching.Sqlite makes things easier as the editor will pull in the correct extension methods.

If using SqliteCache in an ASP.NET Core project, the SQLite-backed cache should be added as an IDistributedCache type by adding the following to your ConfigureServices method, by default located in Startup.cs:

// using NeoSmart.Caching.Sqlite;

public void ConfigureServices(IServiceCollection services)
{
    ...

    // Note: this *must* come before services.AddMvc()!
    services.AddSqliteCache(options => {
        options.CachePath = @"C:\data\bazaar\cache.db";
    });

    services.AddMvc();

    ...
}

Afterwards, the SqliteCache instance will be made available to both the framework and the application via dependency injection, and can be imported and used via either the IDistributedCache abstract type or the concrete SqliteCache type:

// using Microsoft.Extensions.Caching.Distributed;
public class FooModel(DbContext db, IDistributedCache cache)
{
    _db = db;
    _cache = cache;

    cache.SetString("foo", "bar");
    Assert.AreEqual(cache.GetString("foo"), "bar");

    Assert.AreEqual(typeof(NeoSmart.Caching.Sqlite.SqliteCache),
                    cache.GetType());
}

Version 5.0:
- WAL mode and normal synchronization pragmas are set at startup, dramatically improving performance
- ILogger constructor parameter is now optional
- A separate SqliteConnection is used for each SqlCommand instance, fixing threading issues under UWP
- Makes it possible to inject SqliteCache directly (rather than only as IDistributedCache)
- Adds IAsyncDisposable implementation for .NET Core 3.1 and above
- Adds a bulk insert option to insert many key-value pairs quickly (credit to first-time contributor Elias Baumgartner aka @Rap22tor)
- Fixes an issue w/ incorrect handling of user-specified non-UTC expiration dates (credit to first-time contributor Ravindu Liyanapathirana, aka @ravindUwU)

Version 3.1:
- Added .netcoreapp3.1 target
- Switched to SQLitePCLRaw.bundle_e_sqlite3 (same as .NET Core 3.1 web projects)
- SqliteCache is now a sealed class to prevent dispose problems if derived
- Version number aligns with .NET Core semantic versioning
