This Serverless-offline plugin emulates AWS λ and SQS queue on your local machine by using ElasticMQ. To do so, it listens SQS queue and invokes your handlers.
First, add @0xc/serverless-offline-aws-sqs
to your project:
yarn add @0xc/serverless-offline-aws-sqs
Then inside your project's serverless.yml
file, add following entry to the plugins section before serverless-offline
(and after serverless-webpack
if presents): @0xc/serverless-offline-aws-sqs
.
plugins:
- serverless-webpack
- "@0xc/serverless-offline-aws-sqs"
- serverless-offline
Ths configuration of function of the plugin follows the serverless documentation.
functions:
mySQSHandler:
handler: handler.default
events:
- sqs:
queueName: MyQueue
arn:
Fn::GetAtt:
- MyQueue
- Arn
resources:
Resources:
MyQueue:
Type: AWS::SQS::Queue
Properties:
QueueName: MyQueue
Inside your functions you could use a wrapper to switch between local and (aws) production environment.
const AWS = require("aws-sdk");
let options = {};
// connect to local ElasticMQ if running offline
if (process.env.IS_OFFLINE) {
options = {
apiVersion: "2012-11-05",
region: "localhost",
endpoint: "http://0.0.0.0:9324",
sslEnabled: false
};
}
const client = new AWS.SQS(options);
export default client;
The configuration of aws.SQS
's client of the plugin is done by defining a custom: serverless-offline-sqs
object in your serverless.yml
with your specific configuration.
You could use ElasticMQ with the following configuration:
custom:
"@0xc/serverless-offline-aws-sqs":
apiVersion: "2012-11-05"
endpoint: http://0.0.0.0:9324
region: eu-west-1
accessKeyId: root
secretAccessKey: root
skipCacheInvalidation: false
Before you start your serverless functions you ElasticMQ needs to run.
docker run -it -p 9324:9324 s12v/elasticmq:latest
Queues will be automatically created.
PLEASE HELP ME TO GET THIS DONE! EVERY PR IS WELCOME.
