• See samples

In your local environment (PC or else)

  cd samples/
  npm install
  npm run zip ## create app.zip
  

• Create a Node-RED flow

  export S3_BUCKET=XXXXXX
  export AWS_LAMBDA_FUNCTION_NAME=YYYYYYY   ## this must be the same as the lambda function name on AWS.
  npm run dev
  

  access the URL http://localhost:1880 , and create and deploy a flow using the lambda nodes.
  Flow files save in S3.
