Shared Resources Extensions
Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com
To create your own Shared Resource Extensions, you define a module with the methods in the app/shared/extensions folder. Here’s a simple example:
app/shared/extensions/sqs_extension.rb
module SqsExtension
def sqs_queue(logical_id, props={})
defaults = { message_retention_period: 120 }
props = defaults.merge(props)
resource(logical_id, "AWS::SQS::Queue", props)
output(logical_id)
end
end
After the module is defined, you can use the method in your Shared Resource like so:
app/shared/resources/list.rb
class List < Jets::Stack
sqs_queue(:fastpass, receive_message_wait_time_seconds: 20)
end
The code above creates an SQS Queue with a message_retention_period of 120 seconds and a receive_message_wait_time_seconds of 20 seconds. By creating your own resource extensions, you can shorten your code and remove duplication.
Note: The sqs_queue is an example and is actually already implemented by Jets. We’re using it for demonstrative purposes.
