What is the best way to track and increment the versions of serverless framework based projects

I'd been looking for a way to track the version of each serverless microservice individually. Here's a plugin I wrote using some references: https://github.com/simrankadept/serverless-ssm-version-tracker

NPM package:

https://www.npmjs.com/package/serverless-ssm-version-tracker

The version format supported is YYYY.MM.DD.REVISION

Hope this helps.
