Public AWS Lambda Function Layers

While migrating some AWS Lambda Functions between AWS accounts, I had to do the inevitable: re-create the Layers for the respective functions. While doing so, I remembered that there are a handful of public layers that I used in production environments in the past (e.g. chrome-aws-lambda, wkhtmltopdf) that I never had to compile, add to AWS, etc.

This got me thinking that the layers I'm using for my functions might be useful for others. So I'm going to list them below (along with their public ARN so that anyone can use them). You'll also find a bit of context when required (e.g. object instantiation instructions).

I'll try and maintain this page as I add more NPM libraries to my AWS Lambda Functions, or if I use other public Layers.

Command to share layer:

Below is a sample bash command to share a Layer (I couldn't find the option in the AWS console to do so). You may need to change /usr/bin/aws to aws or something similar.

AWS_ACCESS_KEY_ID={{key}} AWS_SECRET_ACCESS_KEY={{secret}} /usr/bin/aws lambda add-layer-version-permission \
  --layer-name {{layerName}} \
  --principal '*' \
  --action lambda:GetLayerVersion \
  --version-number {{layerVersion}} \
  --statement-id public \
  --region {{region}}
