Guide for setting up serverless-offline-sqs + serverless-lift + localstack sqs about serverless-plugins

[serg06]

@luismir15 This is my script

# scripts/patch-serverless-offline-sqs.sh

root='.'  # Project root
lib="${root}/node_modules/serverless-offline-sqs/src/sqs.js"

if grep -q patched "$lib"; then
  echo sqs.js already patched
else
  echo sqs.js is missing the patch, applying...
  sed -i "s|const sqsEvent = new SQSEventDefinition|// patched\n    const {queueName} = this.options;\n\n    if (queueName) rawSqsEventDefinition.queueName = queueName;\n\n    const sqsEvent = new SQSEventDefinition|" "$lib"
  echo done
fi

And my package.json has this:

"scripts": {
  "postinstall": "bash scripts/patch-serverless-offline-sqs.sh"
}

@serg06 this guide has been very helpful, so thank you for that. Also, I wanted to ask: how would you apply the patch in a postintall script?

thanks @serg06! I wanted to point out that I was getting an error while running the script

sed: 1: "node_modules/serverless ...": extra characters at the end of n command

I'm in macos so the only work around was to add an empty string in the sed command
sed -i "" "s|const sqsEvent = new SQSEventDefinition|// patched\n const {queueName} = this.options;\n\n if (queueName) rawSqsEventDefinition.queueName = queueName;\n\n const sqsEvent = new SQSEventDefinition|" "$lib"
