DB UX Design System v3 🚂💖

DB UX Design System Version 3 provides robust HTML UI components, reusable visual styles, and powerful tooling to help developers,
designers, and content authors build, maintain, and scale best of class digital experiences.

We’re not designing pages anymore. We’re designing systems of components.

Packages

Package	Content	Version
foundations	CSS/SCSS/Tailwind styles and assets
components	CSS/SCSS styles for components
ngx-core-components	Native Angular components
react-core-components	Native React components
v-core-components	Native Vue 3 components
wc-core-components	Web Components

How to use

Install your preferred package via npm or yarn e.g. npm i @db-ux/react-core-components.

Afterwards you need to add the specific CSS or SCSS files to provide the styles of DB UX Design System (Version 3), as described in the “Styling Dependencies” of each packages README.
We even also provide some examples of integrations.

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).

Components

We maintain a status overview for all components.

Core principals

Consistent & Compliant

DB UX Design System Core Web is part of DB UX Design System,
that are the guidelines for any Personenverkehr Customer and Deutsche Bahn Enterprise website and web applications.

Accessible

DB UX Design System leverages semantic HTML, ARIA roles, states and properties to apply our styles wherever possible, thus
enforcing correct, accessible markup. And we’re quality checking this in partnership with
the Team Digital Accessibility.

Declarative

DB UX Design System uses declarative selectors instead of visual helpers to ensure our HTML class names and structure are human
read- and understandable, lean, performant and so much easier to update.

Evergreen

As DB UX Design System evolves, so does DB UX Design System version 3, meaning apps only need to keep their DB UX Design System Core Web package updated to ensure the latest look and feel.

Migration

From DB UI Core or DB UI Elements to DB UX Design System Core

We’re providing a detailed migration for each component next to the documentation of each component, like e.g.

FAQ

Unexpected “new” colors

We’ve updated to the stable version of DB UX Design System (v3) version >= 1.x, and now the colors that were supposed to be red, are colored in blue (514ec7).

Please have a look at the migration guide from version 0.6.x to version 0.7.x, you need to install and reference the DB Theme, if you’re building a website or web application for Deutsche Bahn.

Things to keep in mind

Developed for and driven by the community

This is mainly a platform providing the space and technology for a common basis of curated components; their development
is mainly driven by the community and adapted out of the work done in projects and through the huge amount of feedback
that we’re gaining out of the community. So please support us in any way possible, this is greatly appreciated!
