# 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
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

This PR introduces a Profiling feature for our story book tests.
It also implements a new CI job : front-sb-test-performance, that only
runs stories suffixed with `.perf.stories.tsx`
## How it works
It allows to wrap any component into an array of React Profiler
components that will run tests many times to have the most replicable
average render time possible.
It is simply used by calling the new `getProfilingStory` util.
Internally it creates a defined number of tests, separated by an
arbitrary waiting time to allow the CPU to give more stable results.
It will do 3 warm-up and 3 finishing runs of tests because the first and
last renders are always a bit erratic, so we want to measure only the
runs in-between.
On the UI side it gives a table of results :

On the programmatic side, it stores the result in a div that can then be
parsed by the play fonction of storybook, to expect a defined threshold.
```tsx
play: async ({ canvasElement }) => {
await findByTestId(
canvasElement,
'profiling-session-finished',
{},
{ timeout: 60000 },
);
const profilingReport = getProfilingReportFromDocument(canvasElement);
if (!isDefined(profilingReport)) {
return;
}
const p95result = profilingReport?.total.p95;
expect(
p95result,
`Component render time is more than p95 threshold (${p95ThresholdInMs}ms)`,
).toBeLessThan(p95ThresholdInMs);
},
```
