This library is an abstraction to setup AWS layers on ServerlessJS framework.

Why use it?

There are some advantages and improvements which makes it more efficient if compared with native layers support.

• It attaches layers automatically for all functions.
• It checks if dependencies were changed before deployment.
  • If not changed, It skip creation of a new layer.
• It supports Python, Ruby and NodeJs.
• It installs and packs dependencies when changed (npm + zip + upload to S3).
• It deploys local folders/directory as a library:
  • It does a checksum hash of the local folders and stores the result on S3 which later on It's compared before a new deployment.
  • Very useful when you want to share a specific directory on your project as a layer shared with different functions.
