DB UI Mono (Alpha) 🚂💖

DB UI Mono 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. Stephen Hay. Citated in a talk by Brad Frost at beyond tellerrand conference.

Packages

Package	Content	Version
foundations	CSS/Scss/Tailwind styles and assets
components	CSS/Scss styles for components
ngx-components	Native Angular components
react-components	Native React components
v-components	Native Vue components

How to use

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

Afterwards you need to add the specific css or scss files to provide the styles of DB UX System. For a detailed overview look at our examples.

Core principals

Consistent & Compliant

DB UI Mono is based on the DB UX Design System, that are the guidelines for any Personenverkehr Customer and Deutsche Bahn Enterprise website and web applications.

Accessible

DB UI Mono 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 UI Mono 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 UI Mono, meaning apps only need to keep their DB UI Mono package updated to ensure the latest look and feel.

More information

Additionally we'll provide some more information over time regrading the whole ecosystem:

• DB UX Design System documentation within the DB Marketingportal (german)
• Confluence / Base Wiki - "Technische Umsetzung des Enterprise UI Design Systems" (german, only available internally)
• Confluence - Web UI Component Library (only available internally)
• Changelog
• Architectural Decision Records
• DB UI Mono 1.x Gitlab repository (only accessible internally)

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!

How to start develop / contribute

npm install
npm run build
npm run start

Please mind the conventions for git commits.

Give us your feedback!

This is only the first version of our framework and we really want your feedback - either within the DB UI Channel by Web Dev Community in Microsoft Teams (only available DB internally), or directly at [email protected]. We're particularly keen to add as many examples to the behaviours as possible, to further clarify them.

Deutsche Bahn brand

As we'd like to perfectly support our users and customers on their digital journey, the usage of Deutsche Bahn brand and trademarks are bound to clear guidelines and restrictions even when being used with the code that we're providing with this product; Deutsche Bahn fully reserves all rights and ownership regarding the Deutsche Bahn brand, even though that we're providing the code of DB UI products free to use and release it under the Apache 2.0 license. Please have a look at our brand portal at https://marketingportal.extranet.deutschebahn.com/ for any further questions and whom to contact on any brand issues.

For any usage outside of Deutsche Bahn websites and applications you must remove or replace any Deutsche Bahn brand and design assets as well as protected characteristics and trademarks. We're even also planning to provide a neutral theme that would make it much easier for you to use our product without the trademarks by Deutsche Bahn.
