# Introduction
closes https://github.com/twentyhq/core-team-issues/issues/591
Same than for `twenty-shared` made in
https://github.com/twentyhq/twenty/pull/11083.
## TODO
- [x] Manual migrate twenty-website twenty-ui imports
## What's next:
- Generate barrel and migration script factorization within own package
+ tests
- Refactoring using preconstruct ? TimeBox
- Lint circular dependencies
- Lint import from barrel and forbid them
### Preconstruct
We need custom rollup plugins addition, but preconstruct does not expose
its rollup configuration. It might be possible to handle this using the
babel overrides. But was a big tunnel.
We could give it a try afterwards ! ( allowing cjs interop and stuff
like that )
Stuck to vite lib app
Closed related PRs:
- https://github.com/twentyhq/twenty/pull/11294
- https://github.com/twentyhq/twenty/pull/11203
In this huge (sorry!) PR:
- introducing objectMetadataItem in contextStore instead of
objectMetadataId which is more convenient
- splitting some big hooks into smaller parts to avoid re-renders
- removing Effects to avoid re-renders (especially onViewChange)
- making the view prefetch separate from favorites to avoid re-renders
- making the view prefetch load a state and add selectors on top of it
to avoir re-renders
As a result, the performance is WAY better (I suspect the favorite
implementation to trigger a lot of re-renders unfortunately).
However, we are still facing a random app freeze on view creation. I
could not investigate the root cause. As this seems to be already there
in the precedent release, we can move forward but this seems a urgent
follow up to me ==> EDIT: I've found the root cause after a few ours of
deep dive... an infinite loop in RecordTableNoRecordGroupBodyEffect...
