# Introduction
Avoid having multiple `isDefined` definition across our pacakges
Also avoid importing `isDefined` from `twenty-ui` which exposes a huge
barrel for a such little util function
## In a nutshell
Removed own `isDefined.ts` definition from `twenty-ui` `twenty-front`
and `twenty-server` to move it to `twenty-shared`.
Updated imports for each packages, and added explicit dependencies to
`twenty-shared` if not already in place

Something changed, which affected the Favorite folder picker checkbox
styles -- fixed it!
Cleaned up code in `CurrentWorkspaceMemberFavoritesFolders` - removed
redundant filtering since favorites are already filtered in
`usePrefetchedFavoritesData`.
Regarding issue #8569 - I am not sure what to do in this case. Since
Folders data is gated by a feature flag, we can't use it in
`CurrentWorkspaceMemberFavoritesFolders` to ensure the favorite section
renders with empty folders. Currently, the section only appears when at
least one favorite exists - may be leave this section open at all times
or fix this bug after removal of the feature flag?
