Integrating components

Learn how to use any third-party component from npm in your Hilla applications.

To use 3rd-party components in Hilla, you first need to install the component from the npm package registry.

For example, the following command installs the latest version of the vanilla-colorful color picker component and adds the dependency in the package.json file in your project:

npm i vanilla-colorful

After installation, you can import and use the component in a view.

The following example shows the hex triplet of the selected color in a Text Field:

Open in a
new tab
import { html, LitElement } from 'lit';
import { customElement, query } from 'lit/decorators.js';

import '@vaadin/text-field';
import type { TextField } from '@vaadin/text-field';

import 'vanilla-colorful';

@customElement('color-picker-view')
export class ColorPickerView extends LitElement {
  @query('#hex')
  hex!: TextField;

  render() {
    return html`
      <vaadin-text-field id="hex" label="HEX" readonly></vaadin-text-field>
      <hex-color-picker @color-changed="${this.colorChanged}"></hex-color-picker>
    `;
  }

  colorChanged(e: CustomEvent) {
    this.hex.value = e.detail.value;
  }
}
