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, especially where sequential deploys are necessary, i.e., where one serverless resource needs to be deployed before the rest.
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.
Example:
smartRun test
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 --deleteTagOnSuccess
to delete the previous tag on the successful execution of
the smart run. If there was no previous tag this has no effect.
Pass --runFirst
to run a package's script before any others. If multiple packages are passed
to this option, they're run in sequence as well. Supports glob patterns.
Pass --runLast
to run a package's script after any others. If multiple packages are passed
to this option, they're run in sequence as well. Supports glob patterns.
Pass --scope
if you want to run the command for a package even if it hasn't changed, but one of its
dependencies has.
Pass --ignore
if you want to ignore a package, but you still want to run the command for
any of its dependents if they've changed.
Special arguments
If --deleteTag
is passed, this simply looks for the most recent tag generated by this
package and deletes it. After which the script exists. Example:
smartRun --deleteTag
Disclaimer
This package is in an early, experimental stage, and is likely to change dramatically between different versions.
