Smithy Go

Smithy code generators for Go and the accompanying smithy-go runtime.

The smithy-go runtime requires a minimum version of Go 1.20.

WARNING: All interfaces are subject to change.

Can I use the code generators?

In order to generate a usable smithy client you must provide a protocol definition, such as AWS restJson1, in order to generate transport mechanisms and serialization/deserialization code ("serde") accordingly.

The code generator does not currently support any protocols out of the box other than the new smithy.protocols#rpcv2Cbor, therefore the useability of this project on its own is currently limited. Support for all AWS protocols exists in aws-sdk-go-v2. We are tracking the movement of those out of the SDK into smithy-go in #458, but there's currently no timeline for doing so.

Plugins

This repository implements the following Smithy build plugins:

ID	GAV prefix	Description
go-codegen	software.amazon.smithy.go:smithy-go-codegen	Implements Go client code generation for Smithy models.
go-server-codegen	software.amazon.smithy.go:smithy-go-codegen	Implements Go server code generation for Smithy models.

NOTE: Build plugins are not currently published to mavenCentral. You must publish to mavenLocal to make the build plugins visible to the Smithy CLI. The artifact version is currently fixed at 0.1.0.

go-codegen

Configuration

GoSettings contains all of the settings enabled from smithy-build.json and helper methods and types. The up-to-date list of top-level properties enabled for go-client-codegen can be found in GoSettings::from().

Setting	Type	Required	Description
service	string	yes	The Shape ID of the service for which to generate the client.
module	string	yes	Name of the module in generated.json (and go.mod if generateGoMod is enabled) and doc.go.
generateGoMod	boolean		Whether to generate a default go.mod file. The default value is false.
goDirective	string		Go directive of the module. The default value is the minimum supported Go version.

Supported protocols

Protocol	Notes
smithy.protocols#rpcv2Cbor	Event streaming not yet implemented.

Example

This example applies the go-codegen build plugin to the Smithy quickstart example created from smithy init:

{
  "version": "1.0",
  "sources": [
    "models"
  ],
  "maven": {
    "dependencies": [
      "software.amazon.smithy.go:smithy-go-codegen:0.1.0"
    ]
  },
  "plugins": {
    "go-codegen": {
      "service": "example.weather#Weather",
      "module": "github.com/example/weather",
      "generateGoMod": true,
      "goDirective": "1.20"
    }
  }
}

go-server-codegen

This plugin is a work-in-progress and is currently undocumented.
