$ # Parse dependencies from source files (-e stands for entry file)
$ npx @redneckz/slice-node-modules -e some-package/lib/index.js
$ # or from package.json
$ npx @redneckz/slice-node-modules -p some-package/package.json

In case of monorepo (just for example):

$ npx @redneckz/slice-node-modules -e monorepo-root/packages/some-lambda/lib/index.js --exclude 'aws-*' --zip some-lambda.zip

AWS Lambda config (CloudFormation):

const logLambda = new Function(this, 'some-lambda', {
  code: new AssetCode('some-lambda.zip'),
  handler: 'monorepo-root/packages/some-lambda/lib/index.handler',
  runtime: Runtime.NODEJS_12_X
});
