Pinqponq.Database.Mongo

A minimal MongoDB connection layer for .NET: registers a shared IMongoClient and the default IMongoDatabase resolved from configuration, plus a ready-made ping health check. Like the other Pinqponq.Database.* packages, it stops at connectivity — no repository base classes, no document mapping conventions, no query helpers beyond paging a find into the shared Pinqponq.Contracts paged response.

Install

dotnet add package Pinqponq.Database.Mongo

Requirements

  • .NET SDK: net8.0, net9.0, or net10.0
  • A reachable MongoDB server
  • MongoDB.Driver (pulled in transitively)

Quick start

using MongoDB.Driver;
using Pinqponq.Database.Mongo.DependencyInjection;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddPinqponqMongo(mongo =>
{
    mongo.ConnectionString = builder.Configuration.GetConnectionString("Mongo")!;
    mongo.DatabaseName = "myapp";
});

builder.Services.AddHealthChecks().AddPinqponqMongo();

var app = builder.Build();

app.MapGet("/users/{id}", async (string id, IMongoDatabase database, CancellationToken ct) =>
{
    var collection = database.GetCollection<MongoDB.Bson.BsonDocument>("users");
    var filter = MongoDB.Driver.Builders<MongoDB.Bson.BsonDocument>.Filter.Eq("_id", id);
    var document = await collection.Find(filter).FirstOrDefaultAsync(ct);
    return document is null ? Results.NotFound() : Results.Ok(document.ToJson());
});

app.Run();

Using the client or database from an injected service:

public sealed class AuditRepository(IMongoDatabase database)
{
    public Task InsertAsync(BsonDocument entry, CancellationToken ct) =>
        database.GetCollection<BsonDocument>("audit-log").InsertOneAsync(entry, cancellationToken: ct);
}

Paging a find

ToPagedResponseAsync counts the documents a find matches and reads only the requested page into a PagedResponseModel<T> of Pinqponq.Contracts, with the same rules as its ToPagedResponse (page size cap, page past the end, ArgumentException for a page number or size under 1). Sort the find first and leave its skip and limit unset.

using Pinqponq.Database.Mongo.Pagination;

var response = await logs.Find(filter)
    .SortByDescending(log => log.Date)
    .ToPagedResponseAsync(paging.Page, paging.Size, page => page.Select(ToDto).ToList(), LogPaging, cancellationToken);

The package references Pinqponq.Contracts for these types, which brings the ASP.NET Core shared framework (Microsoft.AspNetCore.App) with it.

Configuration

MongoOptions, configured through the Action<MongoOptions> delegate passed to AddPinqponqMongo:

Property Type Default Notes
ConnectionString string "" (required) Standard MongoDB connection string (mongodb://... or mongodb+srv://...).
DatabaseName string "" (required) The database resolved into the registered IMongoDatabase.

Options are validated at startup via ValidateOnStart() — both fields are required; a missing DatabaseName fails fast rather than surfacing later as a confusing "database not found" error.

Main types

Type Kind Purpose
AddPinqponqMongo(Action<MongoOptions>) DI extension (IServiceCollection) Registers a shared IMongoClient and the IMongoDatabase resolved from DatabaseName.
AddPinqponqMongo(...) DI extension (IHealthChecksBuilder) Adds a MongoDB ping command health check (name defaults to "mongodb").
MongoOptions Options Connection string and default database name.
MongoHealthCheck Implementation Registered by the health check extension; not usually referenced directly.

Notes / behavior

  • Two singletons, one client. AddPinqponqMongo registers IMongoClient as a singleton built from ConnectionString, and IMongoDatabase as a second singleton resolved via client.GetDatabase(DatabaseName) — both use TryAddSingleton, so an app-provided registration for either interface takes precedence if added first.
  • Health check is a real ping. MongoHealthCheck issues a single { ping: 1 } command against the resolved database via RunCommandAsync<BsonDocument> — it exercises the actual server round trip, not just client-side connection state.
  • No built-in retry policy on the connection layer itself. The MongoDB .NET driver has its own internal retry/reconnection behavior (retryable reads/writes, server discovery); this package does not layer an additional Polly pipeline on top of it, unlike Pinqponq.Database.Postgres and Pinqponq.Database.Mssql.
  • RetryCount was removed. An earlier revision of this package exposed a RetryCount option on MongoOptions; it has since been removed because it did not map cleanly onto the driver's own retry semantics. If you're upgrading from that version, drop the RetryCount assignment — it no longer exists.
  • No repositories, no entities. This package only resolves a client and a database handle. Collection access, document shape, and any ODM/mapping layer are the consuming application's responsibility.
