This AWS Solutions Construct implements an AWS Lambda function connected to an AWS Step Function.

Here is a minimal deployable pattern definition in Typescript:

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from aws_solutions_constructs.aws_lambda_step_function import LambdaToStepFunction
import aws_cdk.aws_stepfunctions as stepfunctions

start_state = stepfunctions.Pass(stack, "StartState")

LambdaToStepFunction(self, "LambdaToStepFunctionPattern",
    lambda_function_props=FunctionProps(
        runtime=lambda_.Runtime.NODEJS_12_X,
        handler="index.handler",
        code=lambda_.Code.from_asset(f"{__dirname}/lambda")
    ),
    state_machine_props=StateMachineProps(
        definition=start_state
    )
)
```

## Initializer

```text
new LambdaToStepFunction(scope: Construct, id: string, props: LambdaToStepFunctionProps);
```

*Parameters*

* scope [`Construct`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_core.Construct.html)
* id `string`
* props [`LambdaToStepFunctionProps`](#pattern-construct-props)

## Pattern Construct Props

| **Name**     | **Type**        | **Description** |
|:-------------|:----------------|-----------------|
|existingLambdaObj?|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Existing instance of Lambda Function object, if this is set then the lambdaFunctionProps is ignored.|
|lambdaFunctionProps?|[`lambda.FunctionProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.FunctionProps.html)|User provided props to override the default props for the Lambda function.|
|stateMachineProps|[`sfn.StateMachineProps`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-stepfunctions.StateMachineProps.html)|User provided props for the sfn.StateMachine.|

## Pattern Properties

| **Name**     | **Type**        | **Description** |
|:-------------|:----------------|-----------------|
|lambdaFunction|[`lambda.Function`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-lambda.Function.html)|Returns an instance of the Lambda function created by the pattern.|
|stateMachine|[`sfn.StateMachine`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-stepfunctions.StateMachine.html)|Returns an instance of StateMachine created by the construct.|
|stateMachineLogGroup|[`logs.LogGroup`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-logs.LogGroup.html)|Returns an instance of the LogGroup created by the construct for StateMachine|
|cloudwatchAlarms|[`cloudwatch.Alarm[]`](https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-cloudwatch.Alarm.html)|Returns a list of alarms created by the construct.

## Default settings

Out of the box implementation of the Construct without any override will set the following defaults:

### AWS Lambda Function

* Configure least privilege access IAM role for Lambda function
* Enable reusing connections with Keep-Alive for NodeJs Lambda function
* Enable X-Ray Tracing

### AWS Step Function

* Enable CloudWatch logging for API Gateway
* Deploy best practices CloudWatch Alarms for the Step Function
