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.
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)
Rather than including module folders (e.g.
node_modules/foo/**, it now includes a list of actual files (e.g.
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)
