# 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 !
## Introduction
Added coverage on the `useDeleteOneRecord` hooks, especially its
optimistic behavior feature.
Introduced a new testing tool `InMemoryTestingCacheInstance` that has
builtin very basic expectors in order to avoid future duplication when
covering others record hooks `update, create, destroy` etc etc
## Notes
Added few comments in this PR regarding some builtin functions I've
created around companies and people mocked object model and that I think
could be cool to spread and centralize within a dedicated "class
template"
Also put in light that unless I'm mistaken some tests are running on
`RecordNode` and not `RecordObject`
Took few directions on my own that as I always I would suggestion nor
remarks on them !
Let me know
## Misc
- Should we refactor `useDeleteOneRecord` tests to follow `eachTesting`
pattern ? => I feel like this is inappropriate as this hooks is already
high level, the only plus value would be less tests code despite
readability IMO
