"Build SOURCE using NODE and INPUTS.
The builder will remove Node.js packages listed in ABSENT-DEPENCENCIES from
the 'package.json' file's 'dependencies' and 'devDependencies' tables. This
mechanism can be used both avoid dependencies we don't want (e.g. optional
features that would increase closure size) and to work around dependencies
that haven't been packaged for Guix yet (e.g. test utilities)."
;; Before #:absent-dependencies existed, this scenario was often handled by
;; deleting the 'configure phase. Using #:absent-dependencies, instead,
;; retains the check that no dependencies are silently missing and other
;; actions performed by 'npm install', such as building native
;; addons. Having an explicit list of absent dependencies in the package
;; definition should also facilitate future maintenence: for example, if we
;; add a package for a test framework, it should be easy to find all the
;; other packages that use it and enable their tests.
