Custom Interfaces

Custom Interfaces allow you to create new ways of viewing or interacting with field data on the Item Detail page. Learn more about Interfaces.

Extension Entrypoint

The entrypoint of your interface is the index file inside the src/ folder of your extension package. It exports a configuration object with options to configure the behavior of your interface. When loading your interface, this object is imported by the Directus host.

Example of an entrypoint:

import InterfaceComponent from './interface.vue';

export default {
	id: 'custom',
	name: 'Custom',
	icon: 'box',
	description: 'This is my custom interface!',
	component: InterfaceComponent,
	options: null,
	types: ['string'],

Available Options

  • id — The unique key for this interface. It is good practice to scope proprietary interfaces with an author prefix.
  • name — The human-readable name for this interface.
  • icon — An icon name from the material icon set, or the extended list of Directus custom icons.
  • description — A short description (<80 characters) of this interface shown in the App.
  • component — A reference to your interface component.
  • options — The options of your interface. Can be either an options object or a dedicated Vue component.
  • types — An array of supported types.
  • localTypes — An array of local types. Accepts standard, file, files, m2o, o2m, m2m, m2a, presentation, translations and group. Defaults to standard.
  • group — The group this interface is shown at when creating a field. Accepts standard, selection, relational, presentation, group or other. Defaults to other.
  • relational — A boolean that indicates if this interface is a relational interface.
  • recommendedDisplays — An array of display names which are recommended to be used with this interface.

Interface Component

The interface component is the part of your extension that will be rendered by the Directus App whenever your interface should be used to input some value into a field. This interface component has to be Vue component. The most straightforward way to write a Vue component is to use the Vue Single File Component syntax.

Example of an interface component using the Vue SFC syntax:

	<input :value="value" @input="handleChange($" />

export default {
	props: {
		value: {
			type: String,
			default: null,
	emits: ['input'],
	setup(props, { emit }) {
		return { handleChange };

		function handleChange(value) {
			emit('input', value);

The current value of the field is provided to the component via the value prop. If the value was changed inside your component, it should be emitted to the Directus App by using the input emit.

Available Props

  • value — The value of the field.
  • width — The layout width of the field. Either half, half-right, full, or fill.
  • type — The type of the field.
  • collection — The collection name of the field.
  • field — The key of the field.
  • primaryKey — The current item's primary key.

Available Emits

  • input — Update the value of the field.
  • setFieldValue - Used to set the value of other fields.

Other than this simple API to communicate with the Directus App, the interface component is a blank canvas, allowing you to create anything you need.

Vue Version

The Directus App uses Vue 3. There might be 3rd party libraries that aren't yet compatible with Vue 3.

Accessing Internal Systems

To access internal systems like the API or the stores, you can use the useApi() and useStores() composables exported by the @directus/extensions-sdk package. They can be used inside a setup() function like this:

import { useApi, useStores } from '@directus/extensions-sdk';

export default {
	setup() {
		const api = useApi();

		const { useCollectionsStore } = useStores();
		const collectionsStore = useCollectionsStore();

		// ...

Vue Options API

If you prefer to use the Vue Options API, you can inject the api and stores properties directly.
