This AWS Solutions Construct implements an Amazon S3 bucket connected to an AWS Step Function.

Here is a minimal deployable pattern definition:

const { S3ToStepFunction, S3ToStepFunctionProps } = require('@aws-solutions-constructs/aws-s3-step-function');

const startState = new stepfunctions.Pass(stack, 'StartState');

const props: S3ToStepFunctionProps = {
    stateMachineProps: {
      definition: startState
    }
};

new S3ToStepFunction(stack, 'test-s3-step-function-stack', props);

Initializer

new S3ToStepFunction(scope: Construct, id: string, props: S3ToStepFunctionProps);

Parameters

• scope Construct
• id string
• props S3ToStepFunctionProps

Pattern Construct Props
