## Summary
This PR improves Linaria/WYW pre-build speed and continues the migration
of `twenty-ui` components away from runtime `ThemeContext` reads toward
static CSS variables and theme constants.
### Linaria/WYW profiling plugin improvements (`twenty-shared`)
- **Babel JIT warmup**: added a `buildStart` warmup step that triggers
WYW's Babel JIT compilation before the real build starts, so the first
real file doesn't pay the cold-start penalty
- **`configResolved` hook**: detects dev vs prod mode and resolves the
correct warmup file path relative to `config.root`
- **Dev-only per-file logging**: slow file warnings are now gated behind
`isDevMode`, keeping production/CI build output clean
- **`closeBundle` summary**: moved the final top-slow-files report to
`closeBundle` for accurate end-of-build reporting
- **Removed noisy progress interval logging** in favor of the warmup log
+ final summary
### Migration from `ThemeContext` to static CSS variables / constants
Across `twenty-ui`, replaced runtime `useTheme()` reads with:
- `themeCssVariables` CSS custom properties (colors, spacing)
- Hard-coded design-system constants (`ICON.size.md` → `16`,
`ICON.stroke.sm` → `1.6`) so components no longer need a React context
at render time — enabling Linaria static extraction
**Components migrated:**
- `Button`, `AnimatedButton`, `LightButton`, `LightIconButton`,
`AnimatedLightIconButton`, `ButtonIcon`, `ButtonSoon`
- `ProgressBar` (Framer Motion width animation → CSS `transition`)
- `Info`, `HorizontalSeparator`, `LinkChip`
- `MenuPicker`, `MenuItemLeftContent`, `MenuItemIconWithGripSwap`,
`NavigationBarItem`
- `JsonArrow`, `JsonNestedNode`
- `ModalHeader`
### Other
- Added `aria-valuenow` to `ProgressBar` for accessibility
- `VisibilityHidden` component updated to inline accessibility styles
## Summary
- Move Modal UI components (`Modal`, `ModalContent`, `ModalHeader`,
`ModalFooter`, `ModalBackdrop`) from `twenty-front` to `twenty-ui` as
stateless, reusable components
- Create `ModalStatefulWrapper` in `twenty-front` that connects Jotai
state (`isModalOpenedComponentState`) to the stateless `Modal` via an
`isOpen` prop
- Rename `modalVariant` prop to `overlay` with clearer values: `'dark'`
(default), `'light'` (in-container), `'transparent'` (invisible panel).
Remove unused `'medium'` overlay
- Rename `modalId` to `modalInstanceId` across the entire modal zone
(~30 consumer files)
- Extract `ModalProps` to its own file in
`twenty-ui/types/ModalProps.ts`; extract `ModalStatefulWrapperProps` to
its own file using `Pick<ModalProps, ...>` for shared props
- Extract `ModalBackdrop` to its own file and export from `twenty-ui`;
use it in `UserOrMetadataLoader` instead of a local styled component
- Use `ModalFooter` in `StepNavigationButton` and `ModalHeader` in
`SpreadsheetImportStepperContainer` instead of duplicated `styled.div`
definitions
- Remove unused `onClose` prop from stateless `Modal`; fix `typeof
document` guard in `ModalStatefulWrapper`
- Split shared types into individual files: `ModalSize.ts`,
`ModalPadding.ts`, `ModalOverlay.ts`
- Extract wyw profiling instrumentation from `vite.config.ts` into
reusable `createWywProfilingPlugin` with parametrized threshold and
improved logging
- Delete old `Modal.tsx`, `Modal.styles.ts`, `ModalContent.tsx`,
`ModalHeader.tsx`, `ModalFooter.tsx` from `twenty-front`
- Add comprehensive Storybook stories in `twenty-ui` covering Default,
Confirmation, Small, ExtraLarge, Closed, and Interactive variants
## 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
## Video Demo
https://github.com/user-attachments/assets/c2ed67cf-6a15-4896-9fec-e83fac0e862b
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.
## Summary
This PR adds the `lingui/no-unlocalized-strings` ESLint rule to detect
untranslated strings and fixes translation issues across multiple
components.
## Changes
### ESLint Configuration (`eslint.config.react.mjs`)
- Added comprehensive `ignore` patterns for non-translatable strings
(CSS values, HTML attributes, technical identifiers)
- Added `ignoreNames` for props that don't need translation (className,
data-*, aria-*, etc.)
- Added `ignoreFunctions` for console methods, URL APIs, and other
non-user-facing functions
- Disabled rule for debug files, storybook, and test files
### Components Fixed (~19 files)
- Object record components (field inputs, pickers, merge dialogs)
- Settings components (accounts, admin panel)
- Serverless function components
- Record table and title cell components
## Status
🚧 **Work in Progress** - ~124 files remaining to fix
This PR is being submitted as draft to allow progressive fixing of
remaining translation issues.
## Testing
- Run `npx eslint "src/**/*.tsx"` in `packages/twenty-front` to check
remaining issues
# 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.
# 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

# 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 )
## Misc
- related opened issue preconstruct
https://github.com/preconstruct/preconstruct/issues/617
## Closed related PR
- https://github.com/twentyhq/twenty/pull/11028
- https://github.com/twentyhq/twenty/pull/10993
- https://github.com/twentyhq/twenty/pull/10960
## 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

Issue #6976
@FelixMalfait
I could not do
```
import { Banner } from 'twenty-ui';
const StyledBanner = styled(Banner)
display: flex;
align-items: center;
padding: ${({ theme }) => theme.spacing(8)};
position: absolute;
border-radius: 8px;
&:hover {
background-color: ${({ theme }) => theme.accent.primary};
}
;
```
The styles wont get overridden for Banner, so for now I styled a new
banner in `UnmatchColumnBanner` which is inconsistent.
I couldnt figure out why css properties are not being overridden, need
help!
@Bonapara
Question -
Should the click work on entire banner or just cheveron? For now it just
on cheveron click.
