DatabentoDotNet.Extensions.Hosting

Databento for ASP.NET Core and the .NET generic host: IServiceCollection registration for the historical, reference and live clients, IConfiguration binding, and a hosted live-streaming service with bounded reconnection, an opt-in health check, and metrics.

0.10.0 is this package's first release, and it carries no promise. The four packages beside it spent 0.9.0 and 0.9.1 on nuget.org, installable and explicitly unpromised, and that is what earned them a 1.0. This one has had no such window yet, so it gets the same one rather than a SemVer guarantee on the day it appears. Pin the exact version, and if something here is awkward to call, an issue now is far cheaper than a major version later — that is what this release is for.

using DatabentoDotNet.Dbn;
using DatabentoDotNet.Extensions.Hosting;
using Microsoft.Extensions.Hosting;

var builder = Host.CreateApplicationBuilder(args);

builder.Services.AddDatabento();
builder.Services.AddDatabentoLive().AddRecordHandler<TradePrinter>();

using var host = builder.Build();
await host.RunAsync();

internal sealed class TradePrinter : ILiveRecordHandler
{
    public void OnRecord(scoped RecordRef record)
    {
        if (record.TryGet(out TradeMsg trade))
            Console.WriteLine($"{record.Header.InstrumentId} {trade.Price} x {trade.Size}");
    }

    public ValueTask OnFlushAsync(CancellationToken cancellationToken) => ValueTask.CompletedTask;
}

{
  "Databento": {
    "Live": {
      "Default": {
        "Dataset": "EQUS.MINI",
        "Subscriptions": [{ "Schema": "trades", "Symbols": ["AAPL", "MSFT"] }]
      }
    }
  }
}

No API key in that file — it comes from Databento:ApiKey, or from the DATABENTO_API_KEY environment variable if that key is left unset too.

Dependencies

The four core packages, all four reached transitively so that registering HistoricalClient alone still works with one package reference. Plus Microsoft.Extensions.Hosting.Abstractions, Microsoft.Extensions.Options.ConfigurationExtensions, Microsoft.Extensions.Http (the seam behind a pooled HistoricalClient), and Microsoft.Extensions.Diagnostics.HealthChecks (only reached by code if you call AddHealthCheck).

Documentation

The API reference is the XML documentation shipped inside this package. The full configuration shape, writing a handler, running more than one session, and reconnection are at jerbersoft.github.io/databentodotnet — start with Hosting and Dependency Injection.
