# Introduction
In this PR we've migrated `twenty-shared` from a `vite` app
[libary-mode](https://vite.dev/guide/build#library-mode) to a
[preconstruct](https://preconstruct.tools/) "atomic" application ( in
the future would like to introduce preconstruct to handle of all our
atomic dependencies such as `twenty-emails` `twenty-ui` etc it will be
integrated at the monorepo's root directly, would be to invasive in the
first, starting incremental via `twenty-shared`)

## How to test
In order to ease the review this PR will ship all the codegen at the
very end, the actual meaning full diff is `+2,411 −114`
In order to migrate existing dependent packages to `twenty-shared` multi
barrel new arch you need to run in local:
```sh
yarn tsx packages/twenty-shared/scripts/migrateFromSingleToMultiBarrelImport.ts && \
npx nx run-many -t lint --fix -p twenty-front twenty-ui twenty-server twenty-emails twenty-shared twenty-zapier
```
Note that `migrateFromSingleToMultiBarrelImport` is idempotent, it's atm
included in the PR but should not be merged. ( such as codegen will be
added before merging this script will be removed )

## Upcoming enhancement: ( in others dedicated PRs )
- 1/ refactor generate barrel to export atomic module instead of `*`
- 2/ generate barrel own package with several files and tests
- 3/ Migration twenty-ui the same way
- 4/ Use `preconstruct` at monorepo global level
## Conclusion
As always any suggestions are welcomed !
## Context
With the new permissions system, we now need to hide some items from the
settings navigation and gate some routes so they can't be accessed
directly.
To avoid having to set permission gates in all the component pages, I'm
introducing wrapper at the route level and in the Navigation. This is
not required and is mostly for pages that are strictly mapped to a
single permission, for the rest we still need to use the different hooks
manually but it should avoid a bit of boilerplate for most of the cases.
- currentUserWorkspaceState to access settingsPermissions
- SettingsProtectedRouteWrapper in the router that can take a
settingFeature or a featureFlag as a gate logic, if the currentUser does
not have access to the settingFeature or the featureFlag is not enabled
they will be redirected to the profile page.
- SettingsNavigationItemWrapper & SettingsNavigationSectionWrapper. The
former will check the same logic as SettingsProtectedRouteWrapper and
not display the item if needed. The later will check if all
SettingsNavigationItemWrapper are not visible and hide itself if that's
the case.
- useHasSettingsPermission to get a specific permission state for the
current user
- useSettingsPermissionMap to get a map of all permissions with their
values for the current user
- useFeatureFlagsMap same but for featureFlags
