How to share my own custom fucntions on AWS lambda nodejs

Question

I Currently have a project in AWS with several lambda functions, most of the functions in NodeJS, I want to know if is there a way to create a lambda layer with my own code functions that I use in different lambdas without publish it in npm, I already search in old questions in stack question-1 question-2, but these were not answered

Thanks for help!

Yes, you can create a layer with your common code and share it between your functions. There is official AWS documentation about how to do this: docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html — Ervin Szilagyi

create a folder in your local machine called nodejs
put your "shared" logic in that folder like /nodejs/shared.js
you can zip this nodejs folder and upload as a layer
in your lambda code require the shared.js as const shared = require('/opt/nodejs/shared.js')
