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.
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:
$ cdk --init language typescript
$ yarn add projen-statemachine-exampleimport { 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.'});
}$ cdk init --language python

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.")$ cdk init --language java
$ mvn package.
