Build a custom construct based on an example in an AWS Blog post and use [projen](https://github.com/projen/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*](https://aws.amazon.com/tw/blogs/compute/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:
# How to utilize polyglot packages and deploy
## TypeScript
```bash
$ cdk --init language typescript
$ yarn add projen-statemachine-example
```
```typescript
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
```bash
$ cdk init --language python
$ cat < requirements.txt
aws-cdk.core
scotthsieh_projen_statemachine
EOL
$ python -m pip install -r requirements.txt
```
```python
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.")
```
## Java

$ mvn package

StateMachineApiGatewayExample exampleConstruct = new StateMachineApiGatewayExample(this, "KerKer",
StateMachineApiGatewayExampleProps.builder()
.stageName(stageName)
.partPath(partPath)
.build());

.build());
new CfnOutput(this, "OExecutionOutput", CfnOutputProps.builder()
.value(exampleConstruct.getExecutionInput())
.description("Sample input to StartExecution.")
.build());
}
}
```
## C#
```bash
$ cdk init --language csharp
$ dotnet add src/Csharp package Projen.Statemachine --version 2.0.474
```
```cs
using Amazon.CDK;
using ScottHsieh.Examples;
namespace Csharp
{
public class CsharpStack : Stack
{
internal CsharpStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props)
{
string stageName = "default";
string partPath = "pets";
var exampleConstruct = new StateMachineApiGatewayExample(this, "KerKer", new StateMachineApiGatewayExampleProps
{
StageName = stageName,
PartPath = partPath
});
new CfnOutput(this, "OStateMachine", new CfnOutputProps
{
Value = exampleConstruct.StateMachine.StateMachineArn
});
new CfnOutput(this, "OExecutionOutput", new CfnOutputProps
{
Value = exampleConstruct.ExecutionInput,
Description = "Sample input to StartExecution."
});
}
}
}
