Aspire.Hosting.Nats

NATS hosting integration

Use this integration to model, configure, and orchestrate a NATS resource in an Aspire solution.

Getting started

Add the integration

From your AppHost directory, add the Aspire.Hosting.Nats integration with the Aspire CLI:

aspire add Aspire.Hosting.Nats

Usage example

In the AppHost, add a NATS resource and reference it from another resource with either C# or TypeScript:

C#

var nats = builder.AddNats("nats");

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

TypeScript

const nats = await builder.addNats("nats");

const myService = await builder.addNodeApp("myService", "../my-service", "server.js")
                       .withReference(nats);

Connection Properties

When you reference a NATS resource using WithReference, the following connection properties are made available to the consuming project:

NATS server

The NATS server resource exposes the following connection properties:

Aspire exposes each property as an environment variable named [RESOURCE]_[PROPERTY]. For instance, the Uri property of a resource called nats becomes NATS_URI.
