pefi.persistence

A reusable .NET class library that provides a clean abstraction over MongoDB for PeFi projects. It wraps the MongoDB .NET driver behind a simple generic interface, supports dependency injection, and includes OpenTelemetry-compatible distributed tracing out of the box.

Requirements

  • .NET 9.0
  • A running MongoDB instance

Installation

dotnet add package pefi.persistence

or add a package reference directly:

<PackageReference Include="pefi.persistence" Version="*" />

Usage

Register the persistence layer in your Program.cs or Startup.cs:

// Option 1: direct connection string
builder.Services.AddPeFiPersistance("mongodb://localhost:27017");

// Option 2: fluent configuration
builder.Services.AddPeFiPersistance(options =>
{
    options.ConnectionString = "mongodb://localhost:27017";
});

The connection string can also come from your appsettings.json or any other .NET configuration provider.

Inject IDataStore wherever you need persistence:

public class MyService(IDataStore store)
{
    public Task<MyDoc> AddAsync(MyDoc doc) =>
        store.Add("mydb", "mydocs", doc);

    public Task<IEnumerable<MyDoc>> GetAllAsync() =>
        store.Get<MyDoc>("mydb", "mydocs");

    public Task<IEnumerable<MyDoc>> FindAsync(string name) =>
        store.Get<MyDoc>("mydb", "mydocs", d => d.Name == name);

    public Task RemoveAsync(string id) =>
        store.Delete<MyDoc>("mydb", "mydocs", d => d.Id == id);

    public Task<MyDoc?> UpdateAsync(string id, MyDoc updated) =>
        store.Update<MyDoc>("mydb", "mydocs", d => d.Id == id, updated);
}

API

IDataStore exposes five operations:

Method Description
Add<T>(database, collection, item) Inserts a document and returns it
Get<T>(database, collection) Returns all documents in a collection
Get<T>(database, collection, predicate) Returns documents matching a LINQ predicate
Delete<T>(database, collection, predicate) Deletes documents matching a LINQ predicate
Update<T>(database, collection, predicate, item) Replaces the first document matching a LINQ predicate and returns the updated document, or null if no match was found

All methods are async.

Distributed Tracing

MongoDB operations are automatically instrumented via DiagnosticsActivityEventSubscriber, which emits Activity events compatible with OpenTelemetry. No additional configuration is required.

Build

dotnet build

To produce a NuGet package (also runs automatically on build due to GeneratePackageOnBuild):

dotnet pack -c Release

The .nupkg will be written to bin/Release/.
