## Summary
Completes the migration of the frontend styling system from **Emotion**
(`@emotion/styled`, `@emotion/react`) to **Linaria** (`@linaria/react`,
`@linaria/core`), a zero-runtime CSS-in-JS library where styles are
extracted at build time.
This is the final step of the migration — all ~494 files across
`twenty-front`, `twenty-ui`, `twenty-website`, and `twenty-sdk` are now
fully converted.
## Changes
### Styling Migration (across ~480 component files)
- Replaced all `@emotion/styled` imports with `@linaria/react`
- Converted runtime theme access patterns (`({ theme }) => theme.x.y`)
to build-time `themeCssVariables` CSS custom properties
- Replaced `useTheme()` hook (from Emotion) with
`useContext(ThemeContext)` where runtime theme values are still needed
(e.g., passing colors to non-CSS props like icon components)
- Removed `@emotion/react` `css` helper usages in favor of Linaria
template literals
### Dependency & Configuration Changes
- **Removed**: `@emotion/react`, `@emotion/styled` from root
`package.json`
- **Added**: `@wyw-in-js/babel-preset`, `next-with-linaria` (for
twenty-website SSR support)
- Updated Nx generator defaults from `@emotion/styled` to
`@linaria/react` in `nx.json`
- Simplified `vite.config.ts` (removed Emotion-specific configuration)
- Updated `twenty-website/next.config.js` to use `next-with-linaria` for
SSR Linaria support
### Storybook & Testing
- Removed `ThemeProvider` from Emotion in Storybook previews
(`twenty-front`, `twenty-sdk`)
- Now relies solely on `ThemeContextProvider` for theme injection
### Documentation
- Removed the temporary `docs/emotion-to-linaria-migration-plan.md`
(migration complete)
- Updated `CLAUDE.md` and `README.md` to reflect Linaria as the styling
stack
- Updated frontend style guide docs across all locales
## How it works
Linaria extracts styles at build time via the `@wyw-in-js/vite` plugin.
All expressions in `styled` template literals must be **statically
evaluable** — no runtime theme objects or closures over component state.
- **Static styles** use `themeCssVariables` which map to CSS custom
properties (`var(--theme-color-x)`)
- **Runtime theme access** (for non-CSS use cases like icon `color`
props) uses `useContext(ThemeContext)` instead of Emotion's `useTheme()`
# What
Fully deprecate old relations because we have one bug tied to it and it
make the codebase complex
# How I've made this PR:
1. remove metadata datasource (we only keep 'core') => this was causing
extra complexity in the refactor + flaky reset
2. merge dev and demo datasets => as I needed to update the tests which
is very painful, I don't want to do it twice
3. remove all code tied to RELATION_METADATA /
relation-metadata.resolver, or anything tied to the old relation system
4. Remove ONE_TO_ONE and MANY_TO_MANY that are not supported
5. fix impacts on the different areas : see functional testing below
# Functional testing
## Functional testing from the front-end:
1. Database Reset ✅
2. Sign In ✅
3. Workspace sign-up ✅
5. Browsing table / kanban / show ✅
6. Assigning a record in a one to many / in a many to one ✅
7. Deleting a record involved in a relation ✅ => broken but not tied to
this PR
8. "Add new" from relation picker ✅ => broken but not tied to this PR
9. Creating a Task / Note, Updating a Task / Note relations, Deleting a
Task / Note (from table, show page, right drawer) ✅ => broken but not
tied to this PR
10. creating a relation from settings (custom / standard x oneToMany /
manyToOne) ✅
11. updating a relation from settings should not be possible ✅
12. deleting a relation from settings (custom / standard x oneToMany /
manyToOne) ✅
13. Make sure timeline activity still work (relation were involved
there), espacially with Task / Note => to be double checked ✅ => Cannot
convert undefined or null to object
14. Workspace deletion / User deletion ✅
15. CSV Import should keep working ✅
16. Permissions: I have tested without permissions V2 as it's still hard
to test v2 work and it's not in prod yet ✅
17. Workflows global test ✅
## From the API:
1. Review open-api documentation (REST) ✅
2. Make sure REST Api are still able to fetch relations ==> won't do, we
have a coupling Get/Update/Create there, this requires refactoring
3. Make sure REST Api is still able to update / remove relation => won't
do same
## Automated tests
1. lint + typescript ✅
2. front unit tests: ✅
3. server unit tests 2 ✅
4. front stories: ✅
5. server integration: ✅
6. chromatic check : expected 0
7. e2e check : expected no more that current failures
## Remove // Todos
1. All are captured by functional tests above, nothing additional to do
## (Un)related regressions
1. Table loading state is not working anymore, we see the empty state
before table content
2. Filtering by Creator Tim Ap return empty results
3. Not possible to add Tasks / Notes / Files from show page
# Result
## New seeds that can be easily extended

/>
## -5k lines of code
## No more 'metadata' dataSource (we only have 'core)
## No more relationMetadata (I haven't drop the table yet it's not
referenced in the code anymore)
## We are ready to fix the 6 months lag between current API results and
our mocked tests
## No more bug on relation creation / deletion

# 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

1. Refactor guards to avoid duplicated queries: WorkspaceAuthGuard and
UserAuthGuard only check for existence of workspace and user in the

Current state:

I have some things im not really happy with right now:
* If I have different connections it would be weird to display a one_one
or many_one connection differently
* The edges overlay always at one hand at the source/target (also being
a problem with the 3 dots vs 1 dot)
* I would have to do 4 versions of the 3 dot marker variant as an svg
with exactly the same width as the edges wich is not as easy as it seems
:)
* The initial layout is not really great - I know dagre or elkjs could
solve this but maybe there is a better solution ...
If someone has a good idea for one or more of the problems im happy to
integrate them ;)
