How to use the @aws-cdk/core.Duration.minutes function in @aws-cdk/core

To help you get started, we’ve selected a few @aws-cdk/core examples, based on popular ways it is used in public projects.

Secure your code as it's written. Use Snyk Code to scan source code in minutes - no build needed - and fix issues immediately.

      if: item => DynamoDB.attribute_not_exists(item.id)
    });
    newCount = 1;
  }
  return newCount;
});

// call the incrementer function from another Lambda Function
Lambda.schedule(stack, 'Caller', {
  depends: incrementer.invokeAccess(),
  schedule: Schedule.rate(Duration.minutes(1)),
}, async (_, incrementer) => {
  const newCount = await incrementer.invoke({
    id: 'id'
  });
  console.log(`new count of 'id' is ${newCount}`);
