Query Cookbook

The Cookbook

npm query uses a CSS-like syntax for selecting packages within your project's dependency tree.

This is an informal space for documenting "useful" queries that we've come across or developed.

Not In Engine Spec

Finds production dependencies that do not meet an engine spec. There are entire npx tools that do this. (rsubset coming soon)

npm query '.prod:attr(engines, [node]):not(:semver(^14.17.0 || ^16.13.0 || >=18, :attr(engines, [node]), rsubset))'
