Front components are React components that render directly inside Twenty's UI. They run in an isolated Web Worker using Remote DOM — your code is sandboxed but renders natively in the page, not in an iframe.
Front components can render in two locations within Twenty:
The quickest way to see a front component in action is to register it as a command. Adding a command field with isPinned: true makes it appear as a quick-action button in the top-right corner of the page — no page layout needed:
import { defineFrontComponent } from 'twenty-sdk/define';
const HelloWorld = () => {
return (
<div style={{ padding: '20px', fontFamily: 'sans-serif' }}>
<h1>Hello from my app!</h1>
<p>This component renders inside Twenty.</p>
</div>
);
};
export default defineFrontComponent({
universalIdentifier: '74c526eb-cb68-4cf7-b05c-0dd8c288d948',
name: 'hello-world',
description: 'A simple front component',
component: HelloWorld,
command: {
universalIdentifier: 'd4e5f6a7-b8c9-0123-defa-456789012345',
shortLabel: 'Hello',
label: 'Hello World',
icon: 'IconBolt',
isPinned: true,
availabilityType: 'GLOBAL',
},
});
After syncing with yarn twenty dev (or running a one-shot yarn twenty dev --once), the quick action appears in the top-right corner of the page:
Click it to render the component inline.
| Field | Required | Description |
|---|---|---|
universalIdentifier | Yes | Stable unique ID for this component |
component | Yes | A React component function |
name | No | Display name |
description | No | Description of what the component does |
isHeadless | No | Set to true if the component has no visible UI (see below) |
command | No | Register the component as a command (see command options below) |
Beyond commands, you can embed a front component directly into a record page by adding it as a widget in a page layout. See the definePageLayout section for details.
Front components come in two rendering modes controlled by the isHeadless option:
Non-headless (default) — The component renders a visible UI. When triggered from the command menu it opens in the side panel. This is the default behavior when isHeadless is false or omitted.
Headless (isHeadless: true) — The component mounts invisibly in the background. It does not open the side panel. Headless components are designed for actions that execute logic and then unmount themselves — for example, running an async task, navigating to a page, or showing a confirmation modal. They pair naturally with the SDK Command components described below.
import { defineFrontComponent } from 'twenty-sdk/define';
import { useRecordId, enqueueSnackbar } from 'twenty-sdk/front-component';
import { useEffect } from 'react';
const SyncTracker = () => {
const recordId = useRecordId();
useEffect(() => {
enqueueSnackbar({ message: `Tracking record ${recordId}`, variant: 'info' });
}, [recordId]);
return null;
};
export default defineFrontComponent({
universalIdentifier: '...',
name: 'sync-tracker',
description: 'Tracks record views silently',
isHeadless: true,
component: SyncTracker,
});
Because the component returns null, Twenty skips rendering a container for it — no empty space appears in the layout. The component still has access to all hooks and the host communication API.
The twenty-sdk package provides four Command helper components designed for headless front components. Each component executes an action on mount, handles errors by showing a snackbar notification, and automatically unmounts the front component when done.
Import them from twenty-sdk/command:
Command — Runs an async callback via the execute prop.CommandLink — Navigates to an app path. Props: to, params, queryParams, options.CommandModal — Opens a confirmation modal. If the user confirms, executes the execute callback. Props: title, subtitle, execute, confirmButtonText, confirmButtonAccent.CommandOpenSidePanelPage — Opens a specific side panel page. Props: page, pageTitle, pageIcon.Here is a full example of a headless front component using Command to run an action from the command menu:
import { defineFrontComponent } from 'twenty-sdk/define';
import { Command } from 'twenty-sdk/command';
import { CoreApiClient } from 'twenty-sdk/clients';
const RunAction = () => {
const execute = async () => {
const client = new CoreApiClient();
await client.mutation({
createTask: {
__args: { data: { title: 'Created by my app' } },
id: true,
},
});
};
return <Command execute={execute} />;
};
export default defineFrontComponent({
universalIdentifier: 'e5f6a7b8-c9d0-1234-efab-345678901234',
name: 'run-action',
description: 'Creates a task from the command menu',
component: RunAction,
isHeadless: true,
command: {
universalIdentifier: 'f6a7b8c9-d0e1-2345-fabc-456789012345',
label: 'Run my action',
icon: 'IconPlayerPlay',
},
});
And an example using CommandModal to ask for confirmation before executing:
import { defineFrontComponent } from 'twenty-sdk/define';
import { CommandModal } from 'twenty-sdk/command';
const DeleteDraft = () => {
const execute = async () => {
// perform the deletion
};
return (
<CommandModal
title="Delete draft?"
subtitle="This action cannot be undone."
execute={execute}
confirmButtonText="Delete"
confirmButtonAccent="danger"
/>
);
};
export default defineFrontComponent({
universalIdentifier: 'a7b8c9d0-e1f2-3456-abcd-567890123456',
name: 'delete-draft',
description: 'Deletes a draft with confirmation',
component: DeleteDraft,
isHeadless: true,
command: {
universalIdentifier: 'b8c9d0e1-f2a3-4567-bcde-678901234567',
label: 'Delete draft',
icon: 'IconTrash',
},
});
Inside your component, use SDK hooks to access the current user, record, and component instance:
import { defineFrontComponent } from 'twenty-sdk/define';
import {
useUserId,
useRecordId,
useFrontComponentId,
} from 'twenty-sdk/front-component';
const RecordInfo = () => {
const userId = useUserId();
const recordId = useRecordId();
const componentId = useFrontComponentId();
return (
<div>
<p>User: {userId}</p>
<p>Record: {recordId ?? 'No record context'}</p>
<p>Component: {componentId}</p>
</div>
);
};
export default defineFrontComponent({
universalIdentifier: 'b2c3d4e5-f6a7-8901-bcde-f23456789012',
name: 'record-info',
component: RecordInfo,
});
Available hooks:
| Hook | Returns | Description |
|---|---|---|
useUserId() | string or null | The current user's ID |
useRecordId() | string or null | The current record's ID (when placed on a record page) |
useFrontComponentId() | string | This component instance's ID |
useFrontComponentExecutionContext(selector) | varies | Access the full execution context with a selector function |
Front components can trigger navigation, modals, and notifications using functions from twenty-sdk:
| Function | Description |
|---|---|
navigate(to, params?, queryParams?, options?) | Navigate to a page in the app |
openSidePanelPage(params) | Open a side panel |
closeSidePanel() | Close the side panel |
openCommandConfirmationModal(params) | Show a confirmation dialog |
enqueueSnackbar(params) | Show a toast notification |
unmountFrontComponent() | Unmount the component |
updateProgress(progress) | Update a progress indicator |
Here is an example that uses the host API to show a snackbar and close the side panel after an action completes:
import { defineFrontComponent } from 'twenty-sdk/define';
import { useRecordId } from 'twenty-sdk/front-component';
import { enqueueSnackbar, closeSidePanel } from 'twenty-sdk/front-component';
import { CoreApiClient } from 'twenty-sdk/clients';
const ArchiveRecord = () => {
const recordId = useRecordId();
const handleArchive = async () => {
const client = new CoreApiClient();
await client.mutation({
updateTask: {
__args: { id: recordId, data: { status: 'ARCHIVED' } },
id: true,
},
});
await enqueueSnackbar({
message: 'Record archived',
variant: 'success',
});
await closeSidePanel();
};
return (
<div style={{ padding: '20px' }}>
<p>Archive this record?</p>
<button onClick={handleArchive}>Archive</button>
</div>
);
};
export default defineFrontComponent({
universalIdentifier: 'c9d0e1f2-a3b4-5678-cdef-789012345678',
name: 'archive-record',
description: 'Archives the current record',
component: ArchiveRecord,
});
Adding a command field to defineFrontComponent registers the component in the command menu (Cmd+K). If isPinned is true, it also appears as a quick-action button in the top-right corner of the page.
| Field | Required | Description |
|---|---|---|
universalIdentifier | Yes | Stable unique ID for the command |
label | Yes | Full label shown in the command menu (Cmd+K) |
shortLabel | No | Shorter label displayed on the pinned quick-action button |
icon | No | Icon name displayed next to the label (e.g. 'IconBolt', 'IconSend') |
isPinned | No | When true, shows the command as a quick-action button in the top-right corner of the page |
availabilityType | No | Controls where the command appears: 'GLOBAL' (always available), 'RECORD_SELECTION' (only when records are selected), or 'FALLBACK' (shown when no other commands match) |
availabilityObjectUniversalIdentifier | No | Restrict the command to pages of a specific object type (e.g. only on Company records) |
conditionalAvailabilityExpression | No | A boolean expression to dynamically control whether the command is visible (see below) |
The conditionalAvailabilityExpression field lets you control when a command is visible based on the current page context. Import typed variables and operators from twenty-sdk to build expressions:
import { defineFrontComponent } from 'twenty-sdk/define';
import {
pageType,
numberOfSelectedRecords,
objectPermissions,
everyEquals,
isDefined,
} from 'twenty-sdk/front-component';
export default defineFrontComponent({
universalIdentifier: '...',
name: 'bulk-action',
component: BulkAction,
command: {
universalIdentifier: '...',
label: 'Bulk Update',
availabilityType: 'RECORD_SELECTION',
conditionalAvailabilityExpression: everyEquals(
objectPermissions,
'canUpdateObjectRecords',
true,
),
},
});
Context variables — these represent the current state of the page:
| Variable | Type | Description |
|---|---|---|
pageType | string | Current page type (e.g. 'RecordIndexPage', 'RecordShowPage') |
isInSidePanel | boolean | Whether the component is rendered in a side panel |
numberOfSelectedRecords | number | Number of currently selected records |
isSelectAll | boolean | Whether "select all" is active |
selectedRecords | array | The selected record objects |
favoriteRecordIds | array | IDs of favorited records |
objectPermissions | object | Permissions for the current object type |
targetObjectReadPermissions | object | Read permissions for the target object |
targetObjectWritePermissions | object | Write permissions for the target object |
featureFlags | object | Active feature flags |
objectMetadataItem | object | Metadata of the current object type |
hasAnySoftDeleteFilterOnView | boolean | Whether the current view has a soft-delete filter |
Operators — combine variables into boolean expressions:
| Operator | Description |
|---|---|
isDefined(value) | true if the value is not null/undefined |
isNonEmptyString(value) | true if the value is a non-empty string |
includes(array, value) | true if the array contains the value |
includesEvery(array, prop, value) | true if every item's property includes the value |
every(array, prop) | true if the property is truthy on every item |
everyDefined(array, prop) | true if the property is defined on every item |
everyEquals(array, prop, value) | true if the property equals the value on every item |
some(array, prop) | true if the property is truthy on at least one item |
someDefined(array, prop) | true if the property is defined on at least one item |
someEquals(array, prop, value) | true if the property equals the value on at least one item |
someNonEmptyString(array, prop) | true if the property is a non-empty string on at least one item |
none(array, prop) | true if the property is falsy on every item |
noneDefined(array, prop) | true if the property is undefined on every item |
noneEquals(array, prop, value) | true if the property does not equal the value on any item |
Front components can access files from the app's public/ directory using getPublicAssetUrl:
import { defineFrontComponent, getPublicAssetUrl } from 'twenty-sdk/define';
const Logo = () => ;
export default defineFrontComponent({
universalIdentifier: '...',
name: 'logo',
component: Logo,
});
See the public assets section for details.
Front components support multiple styling approaches. You can use:
style={{ color: 'red' }}twenty-sdk/ui (Button, Tag, Status, Chip, Avatar, and more)@emotion/reactstyled.div patternsimport { defineFrontComponent } from 'twenty-sdk/define';
import { Button, Tag, Status } from 'twenty-sdk/ui';
const StyledWidget = () => {
return (
<div style={{ padding: '16px', display: 'flex', gap: '8px' }}>
<Button title="Click me" onClick={() => alert('Clicked!')} />
<Tag text="Active" color="green" />
<Status color="green" text="Online" />
</div>
);
};
export default defineFrontComponent({
universalIdentifier: 'e5f6a7b8-c9d0-1234-efab-567890123456',
name: 'styled-widget',
component: StyledWidget,
});
