Reference an SQS across stacks

cdk-sqs-share.ts

// At the top of the file define your queue name as an export
export const QUEUE_NAME = `membership-events-queue`;

// Create your SQS queue as normal:

export const composeMembershipEventsHandler = (
  stack: Stack,
  props: ComposeBackgroundEventProps
) => {
  const { env, tables } = props;

  /**
   * Create queues to handle the event data and trigger events
   */
  const dlq = new sqs.Queue(stack, `${env}-membership-events-dlq`, {
    queueName: `${env}-membership-events-dlq`,
    encryption: sqs.QueueEncryption.KMS_MANAGED,
    retentionPeriod: Duration.days(14),
  });
  tagComponent(dlq, "private");

  const queue = new sqs.Queue(stack, `${env}-${QUEUE_NAME}`, {
    queueName: `${env}-membership-events-queue`,
    encryption: sqs.QueueEncryption.KMS_MANAGED,
    deadLetterQueue: {
      maxReceiveCount: 2,
      queue: dlq,
    },
  });
  ...
  };
 
 // Now in your other stack, compose the ARN and import it:
 
 import { QUEUE_NAME } from "~/background-events-stack/membershipEvents";
 
 export const composeMembershipHandlerFunction = (
  stack: Stack,
  props: ComposeHandlerFunction
) => {
  const { env, tables } = props;

  /**
   * Find the queue responsible for handling class based events
   */
  const queueArn = `arn:aws:sqs:${stack.region}:${stack.account}:${env}-${QUEUE_NAME}`;
  const queue = sqs.Queue.fromQueueArn(
    stack,
    `${env}-class-handler-${QUEUE_NAME}`,
    queueArn
  );
...
};
