Smithy Typescript

Smithy code generators for TypeScript.

Generating a client

This repository builds TypeScript declarations and JavaScript clients from Smithy models.

The smithy-typescript-codegen-test package in this repos is an example of how to build a TypeScript client. The steps needed to build a TypeScript client are as follows:

  1. Create a new directory for your package. For example, "foo-client".

  2. Create a build.gradle.kts file with the following contents:

     buildscript {
     repositories {
         mavenCentral()
     }
     dependencies {
         "classpath"("software.amazon.smithy:smithy-cli:[1.33.0,1.34.0[")
     }
 }

 plugins {
     id("software.amazon.smithy").version("0.6.0")
 }

 repositories {
     mavenLocal()
     mavenCentral()
 }

 dependencies {
     implementation("software.amazon.smithy:smithy-model:[1.33.0,1.34.0[")
     implementation("software.amazon.smithy.typescript:smithy-typescript-codegen:0.18.0")
 }

  3. Create a smithy-build.json file with the following contents, substituting "smithy.example#ExampleService" with the name of the service to generate and "smithyexample" with the name of the TypeScript package to create.:

     {
     "version": "1.0",
     "plugins": {
         "typescript-codegen": {
             "service": "smithy.example#ExampleService",
             "targetNamespace": "SmithyExample",
             "package": "smithyexample",
             "packageVersion": "0.0.1",
             "packageJson": {
                 "license": "Apache-2.0"
             }
         }
     }
 }

  4. Create a directory named model. This is where all of your Smithy models will go.

  5. Create a file in the model directory named main.smithy with the following contents:

    $version: "2"

namespace smithy.example

service ExampleService {
    version: "2022-01-01"
    operations: [Echo]
}

operation Echo {
    input := {
        message: String
    } 
    output := {
        message: String
    }
}

  6. Run gradle build (alternatively, you can use a Gradle wrapper).

  7. The generated client can be found in build/smithyprojections/foo-client/source/typescript-codegen.

See the Smithy documentation for more information on build Smithy projects with Gradle.

Steps to build

This repo is under heavy development. You will need to use unreleased features to build.

First, build software.amazon.smithy.* packages and publish them to Maven local:

  • git clone https://github.com/awslabs/smithy.git
  • cd smithy
  • ./gradlew publishToMavenLocal
  • cd ..
  • git clone https://github.com/awslabs/smithy-typescript.git
  • cd smithy-typescript
  • ./gradlew build

If you're consuming smithy or smithy-typescript and have already published locally, run the following command to publish the newest contents in your local repository:

  • ./gradlew clean publishToMavenLocal

You can find the build artifacts of the test package at: build/smithyprojections/smithy-typescript-codegen-test/source/typescript-codegen

Troubleshooting

Many Gradle issues can be fixed by stopping the daemon by running ./gradlew --stop
