Let's suppose you want to create an asynchronous messaging application on aws, then you need to create a SQS and a DLQ to store your processing errors.
Queues can be great in scenarios where your application needs
something done but doesn’t need it done now, or doesn’t even care
about the result. Instead of calling a web service and waiting for it
to complete, you can write the message to a queue and let the same
business logic happen later.
It's show time
Our stack is:
- aws-cdk v2
- typescript ### Instalations
npm i -D @aws-cdk/assert ts-node ts-node-dev typescript aws-cdk
npm i aws-cdk-lib constructs
Before of all we need to bootstrap our project with the command bellow:
npx cdk bootstrap aws://ACCOUNT-NUMBER/REGION
Bootstrapping is the deployment of a AWS CloudFormation template to a specific AWS environment (account and region). The bootstrapping template accepts parameters that customize some aspects of the bootstrapped resources (see Customizing bootstrapping).
Now you can create your Queue and DLQ following the example bellow:
Create SQS is a piece of cake xD
If you want to see a real world project structure example, please take a look at the bottom of this post, is a link to my cdk repository with some examples
