Serverless Param Validate

A simple serverless v1.x plugin to give you a checking & validation capabilities to prevent unwanted execution!

This plugin allows a conditional input that will go through Eval function and if the result doesn't satisfy the condition, it will exit your serverless deployment to avoid unwanted mistakes.

• I'm building this plugin following my needs so i won't update the plugin if i don't need to, but feel free to open a PR if you think this plugin need enhancement.
• I'm not an expert JS developer, so feel free to open PR if there are some codes that can be optimized.

Installation

npm install --save-dev serverless-param-validate

Usage

custom:
  validate:
    deploy:
      - cond: '"${self:provider.region}" == "ap-southeast-1"'
        error: Region must be ap-southeast-1
      - cond: '"${ssm:/architecture-type, ""}" == "verycool"'
        error: Infra type must be very cool. Please change it by fully delete and and redeploy the serverless again
    remove:
      - cond: '"${self:provider.region}" == "ap-southeast-1"'
        error: Region must be ap-southeast-1

Will give result such as:

❯ sls deploy --verbose --region=ap-southeast-1

Start param validation...
  CONDITION_0 - PASSED - "ap-southeast-1" == "ap-southeast-1"
✖ Validation error ("" == "verycool"): Infra type must be very cool. Please change it by fully delete and and redeploy the serverless again
