AWS CDK SQS Construct with alarms and dead letter queue

What it does

Creates:

• two queues, one main and one dead letter. Dead letter has added suffix "--dead-letter" to name passed in queueSettings.queueName
• SNS topic with target configured to email from alarmEmail parameter
• alarms for both queues
  • for main queue: message age, passed as alarmWhenMessageOlderThanSeconds parameter
  • for dead letter: alarm triggered if there is any message

Alarms are configured to be sent as fast as possible. Note that SQS report values to CloudWatch every 5 mins.

export class SampleAppStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
      super(scope, id, props);
      
      new lib.MonitoredQueue(this, 'q1', {
          alarmEmail: 'your-email@test.com',
