serverless-plugin-include-dependencies

This is a Serverless plugin that should make your deployed functions smaller.

It does this by enabling you to add your node_modules folder to the exclude list, then it individually adds each module that your handler depends on.

Usage Example

serverless.yml

service: sample

package:
  exclude:
    - node_modules/** # no need to add this yourself, this plugin does it for you

plugins:
  - serverless-plugin-include-dependencies

functions:
  foo:
    handler: src/handler/foo.handler
  bar:
    handler: src/handler/bar.handler

For even smaller function packages, you can also set:

package:
  individually: true

But be warned: Smaller individual functions can still mean a larger overall deployment. (10 functions that are 3 MB each is more net data tranfer and storage than 1 function that is 6 MB)

New In 2.0 - Exclusion Support

Rather than including module folders (e.g. node_modules/foo/**, it now includes a list of actual files (e.g. node_modules/foo/package.json, node_modules/foo/index.js) and uses the serverless package exclude to filter these files. Excludes must start with node_modules to be considered by this plugin.

The following examples would filter files of your module dependencies:

These would not:

Even though normal matching libraries would match these rules, this library ignores them so that there’s no chance of local excludes conflicting with node_modules excludes.

Unless you know exactly where dependencies will be installed (e.g. several things could depend on aws-sdk) you probably want a rule more like node_modules/**/aws-sdk/** (which will exclude all instances of aws-sdk) and not node_modules/aws-sdk/** (which would only exclude a top-level aws-sdk)
