Aspire.Npgsql library

Registers NpgsqlDataSource in the DI container for connecting PostgreSQL®* database. Enables corresponding health check, metrics, logging and telemetry.

Getting started

Prerequisites

  • PostgreSQL database and connection string for accessing the database.

Install the package

Install the .NET Aspire PostgreSQL Npgsql library with NuGet:

dotnet add package Aspire.Npgsql

Usage example

In the Program.cs file of your project, call the AddNpgsqlDataSource extension method to register a NpgsqlDataSource for use via the dependency injection container. The method takes a connection name parameter.

builder.AddNpgsqlDataSource("postgresdb");

You can then retrieve the NpgsqlDataSource instance using dependency injection. For example, to retrieve the data source from a Web API controller:

private readonly NpgsqlDataSource _dataSource;

public ProductsController(NpgsqlDataSource dataSource)
{
    _dataSource = dataSource;
}

Configuration

The .NET Aspire PostgreSQL Npgsql component provides multiple options to configure the database connection based on the requirements and conventions of your project.

Use a connection string

When using a connection string from the ConnectionStrings configuration section, you can provide the name of the connection string when calling builder.AddNpgsqlDataSource():

builder.AddNpgsqlDataSource("myConnection");

And then the connection string will be retrieved from the ConnectionStrings configuration section:

{
  "ConnectionStrings": {
    "myConnection": "Host=myserver;Database=test"
  }
}

See the ConnectionString documentation for more information on how to format this connection string.

Use configuration providers

The .NET Aspire PostgreSQL Npgsql component supports Microsoft.Extensions.Configuration. It loads the NpgsqlSettings from configuration by using the Aspire:Npgsql key. Example appsettings.json that configures some of the options:

{
  "Aspire": {
    "Npgsql": {
      "DisableHealthChecks": true,
      "DisableTracing": true
    }
  }
}

Use inline delegates

Also you can pass the Action<NpgsqlSettings> configureSettings delegate to set up some or all the options inline, for example to disable health checks from code:

    builder.AddNpgsqlDataSource("postgresdb", settings => settings.DisableHealthChecks = true);

AppHost extensions

In your AppHost project, install the Aspire.Hosting.PostgreSQL library with NuGet:

dotnet add package Aspire.Hosting.PostgreSQL

Then, in the Program.cs file of AppHost, register a Postgres database and consume the connection using the following methods:

var postgresdb = builder.AddPostgres("pg").AddDatabase("postgresdb");

var myService = builder.AddProject<Projects.MyService>()
                       .WithReference(postgresdb);

The WithReference method configures a connection in the MyService project named postgresdb. In the Program.cs file of MyService, the database connection can be consumed using:

builder.AddNpgsqlDataSource("postgresdb");
