Package Exports

@rooks/use-did-update

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@rooks/use-did-update) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@rooks/use-did-update

Note: Future updates to this package have moved to the main package rooks. All hooks now reside in a single package which you can install using

npm install rooks

yarn add rooks

Rooks is completely treeshakeable and if you use only 1 of the 50+ hooks in the package, only that hook will be bundled with your code. Your bundle will only contain the hooks that you need. Cheers!
