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");
