Serverless Plugin Conditional Functions

This plugin allows you to add a custom condition to each function in your serverless.yml, to toggle the deployment of your functions. Effectively, it allows a simple feature-flag per function.

For example, if you want to deploy a function for testing only, but don't want it in production, or vice-versa. The attribute supports simple true/false usage or more complex (see below) conditions.

Installation

npm i serverless-plugin-conditional-functions --save-dev
