Build a custom construct based on an example in an AWS Blog post and use projen to publish to 5 language repositories, i.e., npm, PyPI, Central Maven, NuGet, and Go.

Architecture

This library constrcution is referred to the first example in this AWS blog, Introducing Amazon API Gateway service integration for AWS Step Functions written by Benjanmin Smith. After you deploy the stack with whatever programming language you like, i.e., Typescript, Python, Java, or C sharp, you'll get a view similar to the following diagram: image

How to utilize polyglot packages and deploy

TypeScript

$ cdk --init language typescript
$ yarn add projen-statemachine-example
import { StateMachineApiGatewayExample } from 'projen-statemachine-example';

 export class TypescriptStack extends cdk.Stack {
 constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
     super(scope, id, props);

     const stageName = 'default';
     const partPath = 'pets';
     const exampleConstruct = new StateMachineApiGatewayExample(this, 'KerKer', {
         stageName: stageName, partPath: partPath});

     new cdk.CfnOutput(this, 'OStateMachine', {
         value: exampleConstruct.stateMachine.stateMachineArn});
     new cdk.CfnOutput(this, 'OExecutionOutput', {
         value: exampleConstruct.executionInput, description: 'Sample input to StartExecution.'});
 }

Python

$ cdk init --language python
$ cat <<EOL > requirements.txt
aws-cdk.core
scotthsieh_projen_statemachine
EOL
$ python -m pip install -r requirements.txt
from aws_cdk import core as cdk
from scotthsieh_projen_statemachine import StateMachineApiGatewayExample

class PythonStack(cdk.Stack):
    def __init__(self, scope: cdk.Construct, construct_id: str, **kwargs) -> None:
         super().__init__(scope, construct_id, **kwargs)

         stage_name = 'default'
         part_path = 'pets'
         example_construct = StateMachineApiGatewayExample(
             self, 'PythonStatemachne', stage_name=stage_name, part_path=part_path,
         )

         cdk.CfnOutput(self, "OStateMachine",
             value=example_construct.state_machine.state_machine_arn
         )
         cdk.CfnOutput(self, "OExecutionOutput", value=example_construct.execution_input, description="Sample input to StartExecution.")
