serverless-plugin-reducer
Reduce Node.js lambda package so it contains only lambda dependencies
Plugin for the Serverless Framework v2+
By default Serverless packages whole contents of service folder in which lambda was configured, it raises issues in projects where we maintain many functions under one service.
This plugin ensures that it is only dependencies of given lambda that are packaged and deployed to remote instance
Installation
$ npm install serverless-plugin-reducer
Configuration (within serverless.yml
)
- Ensure individual functions packaging by setting
individually: true
forpackage
group. (See Packaging functions separately)
package: individually: true
- Activate plugin in
serverless.yml
plugins: - serverless-plugin-reducer
- If there are some files that need to be included but escape automatic dependencies resolution (e.g. non Node.js module files, or modules required through dynamically resolved paths) they need to be included through
include
option as e.g.
functions: hello: handler: handler.hello package: include: - non-node-js-module.txt - required-through-dynamic-path.js
- If for some paths module files cannot be found, by default an informative error is thrown. Still if the cases are safe to ignore, you may silence those errors with:
custom: reducer: ignoreMissing: true
Tests
