@db-ux/ngx-core-components

An Angular library containing all styles & components of DB UX Design System (technical components).

Note: Find more information about specific components here

Install

npm i @db-ux/ngx-core-components

Note: This will install @db-ux/core-foundations and @db-ux/core-components as well which contains the css/scss files

Styling Dependencies

Import the styles in scss or css. Based on your technology the file names could be different.

• Default (relative): points to ../assets
• Rollup (rollup): points to @db-ux/core-foundations/assets
• Webpack (webpack): points to ~@db-ux/core-foundations/assets

// styles.scss
@forward "@db-ux/core-components/build/styles/rollup";

/* styles.css */
@import "@db-ux/core-components/build/styles/rollup.css";

Note: The relative file contains optional and all components styles. If you consider performance issues see @db-ux/core-components for more information.

Resolve assets

The current default development config in angular.json doesn't use output hashing. This may cause an issue loading the fonts. Look at this for more information.

As a solution add "outputHashing": "media" to configurations/development inangular.json.

DB Theme

In case that you're building a website or application for Deutsche Bahn, you'll additionally have to install the DB Theme via the @db-ux/db-theme node package (even also available as an inner source node package, as described within that packages README).

Usage

//app.component.ts
import { DBButton } from '@db-ux/ngx-core-components';

@Component({
	// ...
	imports: [
		// ...,
		DBButton
    ],
	standalone: true
	// ...
})

<!-- app.component.html -->
<db-button variant="brand">Button</db-button>

Events

There are 3 ways to use Events in Angular:

ngModel

<db-input
	label="Inputfield"
	name="input-name"
	[(ngModel)]="inputModel"
></db-input>

FormControl

<db-input
	label="Inputfield"
	name="input-name"
	[formControl]="inputControl"
></db-input>

change

<db-input
	label="Inputfield"
	name="input-name"
	(change)="inputModel = $event.target.value"
></db-input>

For developers using AI coding assistants like GitHub Copilot or Amazon Q, we provide the @db-ux/agent-cli tool that automatically adds DB UX Design System documentation to your repository.
