Aspire.Hosting.Nats 13.5.0
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:
| Property Name | Description |
|---|---|
Host |
The hostname or IP address of the NATS server |
Port |
The port number the NATS server is listening on |
Username |
The username for authentication |
Password |
The password for authentication |
Uri |
The connection URI with the format nats://{Username}:{Password}@{Host}:{Port} |
Aspire exposes each property as an environment variable named [RESOURCE]_[PROPERTY]. For instance, the Uri property of a resource called nats becomes NATS_URI.
