## What
Lets app **front components** localize the strings they render,
extending the
existing application-translation pipeline (which today only covers
manifest
labels) to component source. App authors mark strings with a small,
familiar
API; the build extracts and bakes them; the runtime resolves them for
the
user's locale.
```tsx
import { Trans, t, msg, useTranslate } from 'twenty-sdk/front-component';
<Trans>Loading postcard…</Trans>
<Trans context="card-title">Untitled</Trans> // disambiguation
const empty = t('No content yet…'); // works outside JSX
<p>{t('Saved {count} cards', { count })}</p> // interpolation
const STATUSES = [{ id: 'draft', label: msg('Draft') }]; // lazy descriptor
```
## How
- **Runtime** (`twenty-sdk/front-component`): `t()` (eager, usable
anywhere —
event handlers, helpers, module scope), `msg()` (lazy descriptor),
`<Trans>`
(reactive JSX), `useTranslate()` / `useLocale()`. Source-string
fallback,
`{name}` interpolation, and `context` disambiguation. No build-time
macro —
these are plain runtime functions.
- **Extraction**: a `ts-morph` scan collects `t()`/`msg()`/`<Trans>`
strings
from component source into the same `locales/*.json` catalogs the
manifest
pipeline already writes (`twenty dev:translations-extract`).
- **Delivery**: `twenty dev:build` bakes the compiled per-locale catalog
into
each front-component bundle via an esbuild banner, so the runtime
resolves
with **no server or renderer changes**. Locale comes from the execution
context that already flows to the worker.
The catalog key and `generateMessageId` hashing are shared between the
node
extractor and the browser runtime; `<Trans>` text whitespace is
normalized
identically on both sides so multi-line elements resolve.
## Design notes
- Reuses the existing `extract → compile → manifest.translations`
contract and
`generateMessageId`, so component strings flow through the same
machinery as
manifest labels.
- Self-contained in `twenty-sdk` + a shared pure helper; the server is
untouched.
## Scope / follow-ups
- `twenty dev` (watch) does not bake catalogs yet — preview shows source
strings; use `twenty dev:build` (documented). Wiring the watcher is a
follow-up.
- Usage is documented in twenty-docs under **Apps → Translations**
(`developers/extend/apps/translations`).
## Tests
Unit tests for the catalog-key/interpolation helpers, the runtime
resolver
(hit/miss/context/fallback/interpolation), and the ts-morph extractor
(static `t`/`msg`/`<Trans>`, dynamic-skip, dedup, multi-line
whitespace), plus a
compile test for context→messageId. Verified with an adversarial review
pass.

## Summary
**PR 2/4** of the app-metadata-translations stack. Gives app developers
the authoring side, as part of the normal manifest build — and it stays
out of the way of developers who don't translate.
- `twenty-sdk` CLI i18n pipeline: collect translatable strings from the
manifest, generate value-as-key message ids (`sha256(value)` truncated,
byte-identical to the server's `generateMessageId`), a `dev
i18n-extract` command to scaffold per-locale catalog files, and a
compile step folded into `build` that emits `manifest.translations`.
- Opt-in: no `locales/` dir → `compileApplicationTranslations` returns
`undefined` → manifest is unchanged.
- Adds an optional `locale` to the front-component execution context so
components can translate against the host locale.
## Stack
Stacks on #22235 (PR 1/4). Base branch:
`claude/app-translation-1-runtime-resolution`.
## Tests
Unit (vitest): extract/compile round-trip + message-id determinism.
## Verification note
`yarn install` could not complete in the remote dev environment, so
typecheck/lint/tests were not run locally — **CI is the source of
truth**.

## Why
Front components (apps) could `navigate()` to a record's **full page**,
but there was no way to open a specific record in the **side panel**.
More generally, `openSidePanelPage` could navigate to a `SidePanelPages`
enum page but couldn't pass the context most pages need.
## What
`openSidePanelPage`'s params are now a **discriminated union keyed on
`page`**, so each page declares its own typed payload (instead of a flat
bag of optionals whose validity silently depends on `page`). This is
also safer: pages that can't render without context can't be "opened"
into a broken panel.
Wired the param-bearing pages host-side, each bridging to its existing
internal hook:
| `page` | Params | Bridges to |
|---|---|---|
| `ViewRecord` | `recordId`, `objectNameSingular`,
`resetNavigationStack?` | `useOpenRecordInSidePanel` (full-page fallback
on mobile / unsupported objects) |
| `EditRichText` | `recordId`, `objectNameSingular`, `fieldName?` |
`useOpenRichTextInSidePanel` |
| `ComposeEmail` | `connectedAccountId`, `threadId?`, `defaultTo?`,
`defaultSubject?`, `defaultInReplyTo?`, `pageTitle?`, `pageIcon?` |
`useOpenComposeEmailInSidePanel` |
| `ViewFrontComponent` | `frontComponentId`, optional
`recordId`+`objectNameSingular`, `pageTitle`, `pageIcon?`,
`resetNavigationStack?` | `useOpenFrontComponentInSidePanel` |
| *(any other page)* | `pageTitle`, `pageIcon?`,
`shouldResetSearchState?` | `navigateSidePanel` |
`CommandOpenSidePanelPage` now takes the union directly, so headless
command-menu items can open any of these. Threaded through `twenty-sdk`
→ `twenty-front-component-renderer` → host
(`useFrontComponentExecutionContext`), with unit tests per page and the
mobile/unsupported fallbacks.
## Deliberately deferred: `MergeRecords`
`useOpenMergeRecordsPageInSidePanel` takes `objectNameSingular` /
`objectRecordIds` at **hook-init** (it calls `useObjectMetadataItem` /
`useLazyFindManyRecords` at render), so it can't be driven by runtime
app params without refactoring that hook + its current caller. Left out
of this PR — better as its own change.
## Worth a second look (reviewers)
- **`ViewFrontComponent`** lets an app open a front component by id.
Within an app that's clean composition; whether an app should be able to
target *another* app's component is a scoping/security question. The
render still runs under the app's access token, so cross-app fetches
would fail auth — but flagging it explicitly.
## Security note
Side-panel record/page views render natively under the **user's**
session/Apollo client, not the app's scoped token — RLS/field
permissions are enforced as if the user opened it themselves. Same trust
model as `navigate(AppPath.RecordShowPage, …)`.
## Follow-up
A separate PR will centralize the mobile + `canOpenObjectInSidePanel`
guard inside `useOpenRecordInSidePanel` (currently duplicated across
callers, missing in others).
## Validation
> [!NOTE]
> Dependencies wouldn't install in this environment (flaky network
during `yarn install`), so lint / typecheck / jest weren't run locally —
relying on CI. The diff was reviewed manually for type-consistency,
including the discriminated-union narrowing in the host switch.

Reorganizes `twenty-ui`'s component organization to follow how the best
UI libraries (MUI, Mantine, Base UI, Polaris) structure their source,
now that the package has stabilized.
**Taxonomy** — dissolves the meaningless `components/` junk-drawer and
the 107-file `display/` mega-category. New domains/subpaths:
`data-display`, `typography`, `icon`, `surfaces`; `feedback` and
`layout` absorb the rest (banners/callout/info + placeholders →
feedback; modal/card → surfaces; motion + separators → layout).
**Per-component layout** — every component is now
`<domain>/<ComponentName>/<ComponentName>.tsx` with colocated
styles/stories/types, `internal/` for private helpers and `parts/` for
re-exported compound sub-parts. The redundant inner `/components/` is
gone. `icon` and `json-visualizer` are kept as cohesive subsystems.
**Also:** adds a tree-shakeable root barrel (`import { Button } from
'twenty-ui'`), the generator now owns `individual-entry.ts`, and a real
barrel-leak bug is fixed (private `internals/` parts were leaking into
the public API).
Consumer imports (~1.2k files) and the `twenty-sdk` UI aggregator were
updated by codemod. The change is **export-neutral** except 16
intentionally-removed private internals symbols (all verified
unconsumed). Gates green: typecheck, lint, build, size-limit, storybook.

Migrates `twenty-front`, `twenty-sdk`, and
`twenty-front-component-renderer` from `twenty-ui-deprecated` to
`twenty-ui` (mechanical import swap — the packages have API parity) and
deletes the deprecated package along with its workspace/CI/config
wiring.
Also adds `@linaria/react`/`@linaria/core` as direct deps of
`twenty-front` (it used them transitively via the deprecated package).
Note: move the required status check from `ci-ui-status-check` to
`ci-new-ui-status-check`.
Argos: the Storybook box-model/button-reset baseline shift (the bulk of
the visual diffs) is isolated in #21665 — Storybook now loads
twenty-ui's global `reset.scss`, which the production app already ships.
Once #21665 merges and this branch is rebased, the remaining Argos diffs
are component-level visual-parity items only.
## Description
Promotes the next-gen UI library (formerly `twenty-new-ui`) to the name
**`twenty-ui`** (v0.1.0, publishable) and renames the old package to
**`twenty-ui-deprecated`**. Rewrites ~1,730 `twenty-ui` imports →
`twenty-ui-deprecated`, updates all configs/CI/Docker/deps, and migrates
twenty-front's `Toggle` to the new package (first consumer) as a
drop-in.
## Next steps
- Wire the `ui/v*` publish dispatch (`cd-deploy-tag.yaml` +
`.yarnrc.yml`), then tag `ui/v0.1.0` to publish.
- Continue migrating components from `twenty-ui-deprecated` →
`twenty-ui`.
Follow-up to #20525, picks up the clipboard + mouse/pointer events asks
from the "Allow to copy to clipboard in front-component" Slack thread.
`navigator.geolocation` and `getBoundingClientRect` are intentionally
out of scope until we have a permission model.
### `copyToClipboard` host API
New SDK function `copyToClipboard` (in `twenty-sdk/front-component`)
that goes through the host bridge to `useCopyToClipboard` in
`twenty-front`:
```ts
import { copyToClipboard } from 'twenty-sdk/front-component';
await copyToClipboard('hello');
```
Host-side hardening (front-component code is untrusted):
- Drops anything that isn't a non-empty string
- Caps payload at 64KB
- Throttles to 1 call/sec per front-component instance
- Snackbar shows a truncated preview so the user can spot a mismatch
between the affordance they clicked and what actually got copied
### `mousemove` and pointer events
Added to `COMMON_HTML_EVENTS` (and the React mapping) so they fire on
every HTML tag the renderer ships: `mousemove`, `pointerdown/up/move`,
`pointerover/out/enter/leave/cancel`. Generator rerun for
`remote-elements.ts` and `remote-components.ts`.
`SerializedEventData` now also forwards pointer geometry: `pointerId`,
`pointerType`, `pressure`, `tangentialPressure`, `tiltX/Y`, `twist`,
`width/height`, `isPrimary`. Existing positional fields are unchanged.
### Coverage
- New Storybook stories: `HostApi/CopyToClipboard` and
`HtmlTag/Grouping/Div/Events::PointerMove`
- `useFrontComponentExecutionContext` unit tests cover the API call,
preview truncation, type guard, length cap, and rate limit
- Renderer Storybook suite 227 → 229, prebuild bundle count 219 → 221
# Introduction
Support multiple selected record ids for headless front components
### Changes
**Added:**
- `recordIds: string[]` field to `FrontComponentExecutionContext`
- `useRecordIds()` hook to get all selected record IDs
**Deprecated:**
- `recordId` field - use `recordIds` instead
- `useRecordId()` hook - use `useRecordIds()` instead
Backward compatibility is preserved
## Summary
- `SettingsApplicationCustomTab` renders `FrontComponentRenderer` which
calls `useFrontComponentExecutionContext` →
`useLayoutRenderingContext()`, but the settings page never provided a
`LayoutRenderingProvider`
- Every other render site (side panel, command menu, record pages) wraps
`FrontComponentRenderer` with this provider — it was just missed here
- Opening the "Custom" tab in Settings → Applications crashes with:
`LayoutRenderingContext Context not found`
- Fix: wrap with `LayoutRenderingProvider` using `DASHBOARD` layout type
and no target record, matching the pattern used in
`SidePanelFrontComponentPage`
## Test plan
- [ ] Open Settings → Applications → any app with a custom settings tab
- [ ] Click the "Custom" tab — should render the front component without
crashing

- Makes engineComponentKey non-nullable on CommandMenuItem. Adds two new
engine component keys: TRIGGER_WORKFLOW_VERSION and
FRONT_COMPONENT_RENDERER to cover the former standalone cases.
- Unifies the previously separated engine, front component and workflow
runners into a single `CommandRunner` component with a unified
`useMountCommand` hook that handles all command types.
Introduces a progress indicator for command menu items (both engine
commands and front components). When a command is running, the menu item
now displays a percentage alongside the loader spinner instead of just a
spinner.
- Added `commandMenuItemProgressFamilyState` to track per-item progress
and `CommandListItemLoader` to render it
- Exposed `updateProgress` in the twenty-sdk public API so front
components can report execution progress back to the host
- Wired progress reporting into `ExportMultipleRecordsCommand` as the
first consumer, showing CSV export progress
- Progress state is cleaned up on unmount for both engine commands and
headless front components
- Refactor
## Description
- Introduces a new engine command execution model that replaces the
previous approach of mapping `EngineComponentKey` to React components.
Instead, engine commands are now mounted headlessly via
`HeadlessEngineCommandMountRoot`, with their execution context populated
synchronously before mounting.
- Creates new headless command components
- Moves error handling from the SDK layer to the host app by wrapping
all mounted commands with a new `CommandMenuItemErrorBoundary`
The new flow works as follows:
- When a command menu item with an `engineComponentKey` is clicked,
`useCommandMenuItemFrontComponentCommands` calls
`useMountEngineCommand`, which synchronously reads the current context
store (object metadata, selected records, filters, view ID, etc.) and
writes a `MountedEngineCommandContext` into
`mountedEngineCommandsState`.
- The command is then mounted into `mountedEngineCommandsState`, which
triggers `HeadlessEngineCommandMountRoot` to render the corresponding
headless component from `ENGINE_COMPONENT_KEY_HEADLESS_COMPONENT_MAP`,
wrapped in `CommandMenuItemErrorBoundary`,
`ContextStoreComponentInstanceContext.Provider`, and
`EngineCommandComponentInstanceContext.Provider`.
- Each command component reads its execution context and delegates to
one of the 4 execution patterns: `HeadlessEngineCommandWrapperEffect`
(simple actions), `HeadlessConfirmationModalEngineCommandEffect`
(destructive actions needing confirmation),
`HeadlessNavigateEngineCommand` (GO_TO_* commands), or
`HeadlessOpenSidePanelPageEngineCommand` (SEARCH_RECORDS, ASK_AI,
VIEW_PREVIOUS_AI_CHATS).
- After execution, the command self-unmounts via
`useUnmountEngineCommand`, which removes the entry from
`mountedEngineCommandsState` and stops rendering the component.
actions are being renamed to command menu item, they will be migrated to
server and will be served as headless front components

## PR description
- Adds `enqueueSnackbar` to the front component host communication API,
allowing front components to display snack bar notifications (success,
error, info, warning) to the user.
- Introduces `frontComponentId` to the `FrontComponentExecutionContext`
and a `useFrontComponentId` hook, enabling front components to identify
themselves (used for dedupe keys).
- Wires error/success notifications into the `Action`, `ActionLink`, and
`ActionOpenSidePanelPage` SDK components -> actions now catch errors and
display them as snack bars, and `Action` supports an optional
`notifyOnEnd` prop for success feedback.

## Description
- Add `isHeadless` field to `FrontComponent` entity so front components
can run without rendering UI in the command menu
- Introduce headless front component mounting logic:
`HeadlessFrontComponentMountRoot` at the application root,
`useMountHeadlessFrontComponent`, and `useUnmountHeadlessFrontComponent`
hooks to mount/unmount headless components
- Expand the SDK with new action components (`Action`, `ActionLink`,
`ActionOpenSidePanelPage`) and host communication functions
(`openSidePanelPage`, `unmountFrontComponent`)
- Move `CommandMenuPages` type to twenty-shared so the SDK can reference
it for side panel navigation

## Split twenty-sdk build into separate Node and browser targets
The SDK was bundling Node.js code (CLI, SDK API) and browser code (UI
components, front-component renderer) through a single Vite config. This
caused incorrect externalization — Node builtins leaked into browser
bundles and browser-specific chunking logic applied to CLI output.
This PR splits the build into `vite.config.node.ts` and
`vite.config.browser.ts` so each target gets the right externals and
output format.
Also includes a few housekeeping renames:
- `front-component` export path → `front-component-renderer` (matches
what it actually is)
- `front-component-common` merged into `front-component-api` (was a
needless extra module)
## PR Description
This PR:
- Introduces a `FrontComponentHostCommunicationApi`, which allows us to
pass functions to be executed from the worker
- Exposes a navigate function from the host to the front component
remote workers, enabling SDK components to trigger in-app navigation
- Gets rid of `useSyncExternalStore` and makes the execution context
reactive without it
- Refactors and improves the `esbuild` plugin system
