How to use npm packages in AWS Lambda

You cannot load NPM modules without uploading a .zip file.

In order to upload a .zip file, you need:

• Put a lamda function file in a separate directory
• Install necessary npm package(s)
• Make sure the function works locally with node lambdaFunc.js
• Go to the directory and compress the contents (How to create a Zip archive with CLI)
• Upload the function package:

aws lambda update-function-code --function-name poc --region us-east-2 --zip-file fileb://C:/Projects/git/SeasonedDeveloper/path-to-function/lambdaFunc.zip

You mayu need to:

• specify a region with the --region parameter
• configure AWS CLI with aws configure
  • create a user with AWS Access Key & Secret
