lerna-smart-run v0.0.1

lerna-smart-run

Lerna add-on for only running npm scripts for packages changed since previous tag

Background

This package is a glorified wrapper around ordinary lerna run <script> commands, but it implements a system to control the order of execution and an automated, opionated tagging system (based on git branches) that takes advantage of lerna's --since option.

This package is intended for use in CI and CD pipelines.

Usage

Invoke with smartRun <npm script>, where <npm script> is a script from the scripts section of the package.json of one of your lerna packages.

Optional arguments

Pass --tagOnSuccess to generate a tag from the successful execution of the smart run. This tag will be used on the following execution.

Pass --runFirst <package-name> to run the named package before the rest. This is useful for serverless monorepos where the deployment of some services rely on the finished deployment of another resource.

Disclaimer

This package is in an early, experimental stage, and is likely to change dramatically between different versions.
