Size of the aws-xray-sdk-core package dependencies (i.e. the bundle)

[Ignacio Larrañaga]

Hi guys, I'm trying to reduce the size of my bundle in a lambda and discovered that the dependencies added by the aws-xray-sdk-core sum a lot, being specific, a project just with this dependency:

{
  "name": "sample",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "aws-xray-sdk-core": "^3.5.0"
  }
}

Has 5.9M in the node_modules:

724K	@aws-sdk
3.8M	@types
252K	async-hook-jl
 32K	atomic-batcher
396K	aws-xray-sdk-core
144K	cls-hooked
 28K	emitter-listener
 24K	lru-cache
256K	semver
 44K	shimmer
108K	stack-chain
112K	tslib
 32K	yallist

Is there a way to prune some of this context?, e.g. @aws-sdk (which is already packaged in the lambda context), @types, semver?

Can I prune it manually for example to just include aws-xray-sdk-core?

Thanks in advance.

For @aws-sdk it could be removed since AWS Lambda NodeJs Runtime has it. But the others we are not sure, since AWS Lambda does not provide a full list of dependencies by default(and it might be changed without notice?), we cannot guarantee whether XRay SDK work in Lambda after pruning something. So, please prune the dependencies based on your experience if required.
