Maintenance: Remove `@types/node` from Lambda Layers

[dreamorosi]

Summary

Discussed in #1170

^{Originally posted by Muthuveerappanv November 16, 2022}

Layers when unzipped (6.0M)

The @types directory occupies 3.6M in the layers data, Since @types aren't used at runtime, they can be readily removed

Without @types (2.4 M)

I did rm -rf node_modules/@types

Using tools like node-prune

I have had much success with using node-prune as well, it takes away unused, files and reduces the size of node_modules by a good number, but has to be thoroughly tested.

Why is this needed?

Currently the Lambda layers are bundling what it appears to be @types/node which is 3.6MB:

Given that this is a devDependency it probably shouldn't be bundled there in the first place.

Which area does this relate to?

• This request meets Lambda Powertools Tenets
