Custom Displays

Displays are small inline components that allow you to create new ways of viewing field values throughout the App. Learn more about Displays.

1. Setup the Boilerplate

Every display is a standalone "package" that contains at least a metadata file and a Vue component. We recommend using the following file structure:

src/
	index.js
	display.vue

src/index.js

import DisplayComponent from './display.vue';

export default {
	id: 'custom',
	name: 'Custom',
	description: 'This is my custom display!',
	icon: 'box',
	handler: DisplayComponent,
	types: ['string'],
};

• id — The unique key for this display. It is good practice to scope proprietary displays with an author prefix.
• name — The human-readable name for this display.
• description — A short description (<80 characters) of this display shown in the App.
• icon — An icon name from the material icon set, or the extended list of Directus custom icons.
• handler — A function, or reference to your Vue component.
• types — A CSV of supported types.

::: tip

See the TypeScript definition for more info on what can go into this object.

:::

src/display.vue

<template>
	<div>My Custom Display</div>
</template>

<script>
export default {};
</script>

The props you can use in an display are:

• value — The value of the parent field.
• interface - The interface of the parent field.
• interface-options - The options for the parent field's interface.
• type — The type of the parent field.
• collection — The collection name of the parent field.
• field — The key of the parent field.

---

Alternatively, you can specify a function for the handler. This allows you to make simple displays that don't need a full component rendered:

export default {
	id: 'custom',
	name: 'Custom',
	description: 'This is my custom display!',
	icon: 'box',
	handler: function (value) {
		return value.toLowerCase();
	},
	types: ['string'],
};

2. Install Dependencies and Configure the Buildchain

Set up a package.json file by running:

npm init -y

To be read by the Admin App, your custom display's Vue component must first be bundled into a single index.js file. We recommend bundling your code using Rollup. To install this and the other development dependencies, run this command:

npm i -D rollup rollup-plugin-commonjs rollup-plugin-node-resolve rollup-plugin-terser rollup-plugin-vue@5.0.0 @vue/compiler-sfc rollup-plugin-vue@next

You can then use the following Rollup configuration within rollup.config.js:

import { terser } from 'rollup-plugin-terser';
import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import vue from 'rollup-plugin-vue';

export default {
	input: 'src/index.js',
	output: {
		format: 'es',
		file: 'dist/index.js',
	},
	plugins: [terser(), resolve(), commonjs(), vue()],
};

3. Develop Your Custom Display

The display itself is simply a function or a Vue component, providing a blank canvas for creating anything you need.

4. Build and Deploy

To build the display for use within Directus, run:

npx rollup -c

Finally, move the output from your display's dist folder into your project's /extensions/displays folder. Keep in mind that the extensions directory is configurable within your env file, and may be located elsewhere.
