Smithy IDL

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

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://awslabs.github.io/smithy/quickstart.html#complete-example

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

Building Smithy models

The Smithy Gradle Plugin is the best way to get started with building a Smithy model. First, create a smithy-build.json file:

{
    "version": "1.0"
}

Then, apply the Smithy Gradle Plugin in your build.gradle.kts file and run gradle build:

plugins {
   id("software.amazon.smithy").version("0.5.3")
}

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

namespace com.example

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

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