GitHub quietly sneaked out a new feature in the last few weeks: Composite Actions. This solves one of my biggest issues with GH Actions which is that yaml workflow steps couldn't be re-used. This means I have lots of repos with the exact same yaml workflow, or roughly the same workflow with slight variations. For example these 3 repos (and others) currently use the exact same workflow for CI:

• datapackage-to-datasette
• commitment
• datasette-mailto-links

Composite actions essentially allows yaml workflow steps to be packaged and re-used in the same way that javascript actions or docker actions can be, so I can package this up as a shared action and use it in lots of repos. This is a feature I have been hoping would be added to Actions for some time and I'm looking forward to DRYing up my workflows across repos over the coming weeks.
