zix99/snssqs-mock repository overview

⁠SNS-SQS Mock

This small application uses ElasticMQ + An express script to simulate the SNS-SQS interaction we see in a production or deployed environment.

⁠Using

docker run -it --rm -p 9325:9325 -p 9324:9324 zix99/snssqs-mock:latest

Two ports are exposed by the docker container:

• 9324: SQS Mock (ElasticMQ)
• 9325: SNS Mock

⁠Publishing to a topic

There are 3 ways to publish to a SNS topic:

• Publish to the REST endpoint with the topic in the route, eg http://localhost:9325/mytopic
• Public to the REST endpoint with a valid ARN in the SNS topic, which will be parsed and the topic found
• No topic will result in the topic undefined

⁠Topic and Queue Creation

By default, if a queue is not found for a given topic, a queue will automatically be generated with the topic name.

You can also export SNS_TOPIC_MAP in the following format on the docker run call:

-e SNS_TOPIC_MAP=topic1:queue1,topic1:queue2,topic2:queue3

Every time a topic is published to, it will route to one or more named queues. By defining the topic map, the topic will no longer follow the default logic of publishing to a queue by the topic name.
