## 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()`
## Migrate twenty-ui from Emotion to Linaria
Completes the migration of all `twenty-ui` components from Emotion
(runtime CSS-in-JS) to Linaria (zero-runtime, CSS extracted at build
time).
- Replaced `@emotion/styled` with `@linaria/react` across ~170 files
- Removed all Emotion dependencies from `twenty-ui`
- Introduced a CSS custom properties-based theme system:
`themeCssVariables` where every leaf is a `var(--t-xxx)` reference,
injected onto `document.documentElement` by
`ThemeCssVariableInjectorEffect`
- No more `theme` prop threading — styled components reference
`themeCssVariables.x.y` directly at build time
- Updated `twenty-front` consumers to remove `theme={theme}` prop
passing
**Before / After:**
```tsx
// Emotion
color: ${({ theme }) => theme.font.color.primary};
padding: ${({ theme }) => theme.spacing(4)};
// Linaria
color: ${themeCssVariables.font.color.primary};
padding: ${themeCssVariables.spacing[4]};
```
### Theme architecture
Two build-time utilities produce the theme system:
- **`buildThemeReferencingRootCssVariables`** — walks the theme object
and builds a nested mirror where every leaf is a `var(--t-xxx)` string
(evaluated at build time by wyw-in-js)
- **`prepareThemeForRootCssVariableInjection`** — walks the runtime
theme and collects flat `[--css-variable-name, value]` pairs, injected
onto `document.documentElement` by `ThemeCssVariableInjectorEffect`
Both share naming conventions (`camelToKebab`, `SPACING_VALUES`,
`formatSpacingKey`) and are unit tested.
### Spacing cleanup
Spacing scale now uses integers 0–32 (generated via loop), with `0.5`
and `1.5` as the only fractional exceptions. All other fractional
spacing usages (`0.25`, `0.75`, `1.25`, `2.5`, `3.5`) were replaced with
literal pixel values across ~20 twenty-front files.
### Framer Motion integration
Linaria doesn't support `styled(motion.div)` — wrapping a motion element
with `styled()` causes the component body to be stripped at build time.
Instead, we define the styled component first, then wrap it with
`motion.create()`:
```tsx
const StyledBarBase = styled.div`
background-color: ${themeCssVariables.font.color.primary};
height: 100%;
`;
const StyledBar = motion.create(StyledBarBase);
```
### Block interpolations
Linaria doesn't support interpolations that return multiple CSS
declarations (Linaria wraps the entire block in a single `var()`,
producing invalid CSS). These were split into individual property
interpolations:
```tsx
// Emotion — single interpolation returning multiple declarations
border-left: ${({ divider, theme }) => {
const border = `1px solid ${theme.border.color.light}`;
return divider ? `border-${divider}: ${border}` : '';
}}
// Linaria — one interpolation per property
border-left: ${({ divider }) =>
divider === 'left' ? `1px solid ${themeCssVariables.border.color.light}` : 'none'};
border-right: ${({ divider }) =>
divider === 'right' ? `1px solid ${themeCssVariables.border.color.light}` : 'none'};
```
### Dynamic styles via CSS variables
When a component needs to compute styles from multiple props with
complex branching logic (e.g. `Button` combining `variant`, `accent`,
`inverted`, `disabled`, `focus`, `position`), Linaria's prop
interpolations become unwieldy. In those cases we use a
`computeDynamicStyles` function that returns a `CSSProperties` object
injected via `style={}`, referenced from the static CSS with `var()`:
```tsx
const StyledButton = styled.button`
background: var(--btn-bg);
border-color: var(--btn-border-color);
&:hover { background: var(--btn-hover-bg); }
`;
const dynamicStyles = useMemo(() => {
const s = computeButtonDynamicStyles(variant, accent, ...);
return { '--btn-bg': s.background, '--btn-hover-bg': s.hoverBackground } as CSSProperties;
}, [variant, accent, ...]);
return <StyledButton style={dynamicStyles} />;
```
### CSS var + unit concatenation
CSS custom properties can't be concatenated with unit suffixes directly
(`var(--x)px` is invalid). Values that need units use `calc()`:
```tsx
// Broken
transition: background ${themeCssVariables.animation.duration.instant}s ease;
// Fixed
transition: background calc(${themeCssVariables.animation.duration.instant} * 1s) ease;
```
## PR description
This PR:
- Creates a TypeScript-based extractor that discovers all exported
twenty-ui components by scanning barrel files, extracting
props/slots/events via ts-morph type analysis, and generating the remote
DOM bindings automatically.
- Adds a new ESLint rule which enforces all *Props types in twenty-ui
components to be exported, which is required for the extractor to
discover component prop types. Existing twenty-ui components are updated
to comply with this rule.
- Extends the remote DOM generation to support slots, per-component
events, forwardRef wrappers, and richer property types (array, object,
function)
## Edge cases to fix in another PR
- Icons cannot be rendered inside buttons
- IconButtons throw an error when mounted
- MenuItems are not displayed correctly
- MenuItemNavigate throws on click

How it works
- `manifest.json` files are now committed when apps are published to our
repo
- to display available apps, from the server, we read into our github
repo, using a pod-scoped cache
- feature flagged
- app installation will be behind permission gate MARKETPLACE_APPS
Limitations and what is yet to develop
- content and settings tabs
- installed apps tab
- app installation
- test and potentially fix reading from .manifest.json once [Reshape
manifest
structure](https://github.com/twentyhq/core-team-issues/issues/2183) is
done. additional work is expected on assets notably. (couldnt properly
do it here as manifest.json will only be committed after this pr)
- we only read in community/ folder for now - we may want tochange that
- the cache is rather artisanal for now and scoped by pod - we may want
to change that
Upgraded from 8.6.15 to 9.1.17 in two steps:
- 8.6.15 -> 9.0.0
- 9.0.0 -> 9.1.17
I had to disable `storybook-addon-cookie` since it is not supported for
Storybook 9. However, I do intend to upgrade to Storybook 10 when this
is merged, so we can replace the aforementioned add-on with this fork
specifically created to support Storybook 10 and above:
https://www.npmjs.com/package/@storybook-community/storybook-addon-cookie.
Additionally, once we upgrade to Version 10 successfully, I will start
looking into integrating the official Vitest add-on.
# Complete color refactoring
Closes https://github.com/twentyhq/core-team-issues/issues/1779
- Updated all colors to use Radix colors with P3 color space allowing
for brighter colors
- Created our own gray scale interpolated on Radix's scale to have the
same values for grays as the old ones in the app
- Introduced dark and light colors as well as there transparent versions
- Added many new colors from radix that can be used in the tags or in
the graphs
- Updated multiple color utilities to match new behaviors
- Changed the computation of Avatar colors to return only colors from
the theme (before it was random hsl)
These changes allow the user to use new colors in tags or charts, the
colors are brighter and with better contrast. We have a full range of
color variations from 1 to 12 where before we only had 4 adaptative
colors.
All these changes will allow us to develop custom themes for the user
soon, where users can choose their accent colors, background colors and
there contrast.
Closes#12571
~~## What’s broken?~~
~~Toggling a feature flag in the admin panel re-renders the entire table
and uses a Framer Motion slide animation for the knob. Each animation
frame forces a layout recalculation all the way up, causing the page to
“jump.”~~
~~## What’s the fix?~~
~~Swap out the Framer Motion toggle for a pure-CSS version:~~
~~- Container is position: relative~~
~~- Knob is position: absolute and moves via left~~
~~- A transition: left 0.3s ease + will-change: left hint runs on the
compositor layer~~
~~This keeps the smooth slide effect but never triggers parent layout
reflows.~~
~~No changes to the public <Toggle> API or behavior.~~
~~TODO: test all toggles in app and stories if any~~

# 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
Removed redundant handleSave and handleSubmit props in domain settings.
Integrated form submission logic directly into form components, ensuring
consistent behavior and reducing complexity. Updated button components
to explicitly support the "type" attribute for improved accessibility
and functionality.

## Context
Adding a defaultRole to each workspace, this role will be automatically
added when a member joins a workspace via invite link or public link
(seeds work differently though).
Took the occasion to refactor a bit the frontend components, splitting
them in smaller components for more readability.
## Test

/>
## Context
Introducing the "Permissions" tab in the role page
Next: Need to address some css improvements, some components might be
reusable and it still does not fully match the figma (icon missing for
permission types for example). We decided to merge like this for now so
we have something functional and I will update the code in an upcoming
PR

## Summary
This pull request addresses a minor issue reported in the #8171 , which
was causing misalignment in the content and overall theme spacing.
Fixes#8171
## Fix
> Removed the 5px padding based on the check if its non hoverable, the
current gap between the checkbox and the icon is 8px as expected.
> For the small variant the total size of the non hoverable component is
14x14 as mentioned in the design, for hoverable its 24x24
> For the Large variant the total size of the non hoverable component is
20x20 as mentioned in the design, for hoverable
its 32x32
> checked for the hoverable checkbox component as well working as
expected
