Build Status

Smithy defines and generates clients, services, and documentation for any protocol.

Smithy IDL

Smithy models define a service as a collection of resources, operations, and shapes.

$version: "2"

namespace example.weather

service Weather {
    version: "2006-03-01"
    resources: [City]
    operations: [GetCurrentTime]
}

resource City {
    identifiers: { cityId: CityId }
    read: GetCity
    list: ListCities
    resources: [Forecast]
}

// See the full example at https://smithy.io/2.0/quickstart.html#complete-example

Find out more about modeling a service with Smithy in the Quick Start guide.

Building Smithy models

[!IMPORTANT]
Before you proceed, make sure you have the Smithy CLI installed.

The Smithy CLI is the easiest way to get started with building Smithy models. First, create a smithy-build.json file:

{
    "version": "1.0",
    "sources": ["model"]
}

Next, create your first model model/main.smithy:

$version: "2"

namespace com.example

service ExampleService {
    version: "2020-05-27"
}

Finally, run smithy build to build the model with the Smithy CLI.

Find out more about building artifacts of your Smithy model in the Building Smithy Models guide. For more examples, see the examples repository
