@gentleduck/libs

The helpers every package shares

cn(), filteredObject, groupArray, parseDate, and the other small utilities gentleduck runs on. Each helper has its own subpath.

cn()
Merges class names with clsx and tailwind-merge. When Tailwind utilities conflict, the last one wins.
filteredObject
Picks or omits object keys with a typed result. A typed stand-in for lodash.pick and omit.
groupArray
Groups a list by key or by function and returns a record of matching items per group.
groupDataByNumbers
Buckets numbers into explicit ranges. Useful for histograms, charts, and ad hoc analytics on number arrays.
parseDate
Turns strings, numbers, or Date inputs into a real Date. Invalid input returns null, so you can return early.
Subpath imports
Every helper has its own entry point, like @gentleduck/libs/cn or /parse-date. No framework dependencies.

Install

Import each helper from its own subpath.
