## What kind of change does this PR introduce? Bug fix, docs update ## What is the current behavior? - The breadcrumb component docs at `/design-system/docs/components/breadcrumb` reference six `ComponentPreview` demos, but the example components were never implemented and their registry entries were commented out. The page rendered without working previews. Unrelated but snuck in: - The “responsive” Admonition example is a H2 instead of H3 like the others. - The design system ⌘K command switcher grows to the full height of its nav items instead of scrolling within a bounded list. Closes DEPR-607 Closes DEPR-608 ## What is the new behavior? - Adds six breadcrumb example components (`breadcrumb-demo`, `breadcrumb-separator`, `breadcrumb-dropdown`, `breadcrumb-ellipsis`, `breadcrumb-link`, `breadcrumb-responsive`) under `apps/design-system/registry/default/example/` - Re-enables the corresponding entries in `registry/examples.ts` and rebuilds `__registry__/index.tsx` - Fixes invalid nested `<li>` markup in the responsive breadcrumb demo that caused a hydration error Also includes two small unrelated fixes: - Caps the ⌘K switcher `CommandList` at `max-h-[300px]` so it scrolls instead of stretching - Corrects the admonition fragment docs header type ## Additional context Test plan: - [ ] Run `pnpm dev:design-system` and open `/docs/components/breadcrumb` - [ ] Confirm all six breadcrumb previews render - [ ] Confirm no hydration warnings in the browser console for the responsive example - [ ] Open the ⌘K switcher and confirm the list scrolls within a bounded height <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added multiple Breadcrumb demos to the design system gallery, including link, dropdown, ellipsis, separator, and responsive variants. * Enabled these Breadcrumb demos in the examples registry. * **Documentation** * Updated the “Responsive” docs heading level. * **Style** * Constrained the command menu list height inside the dialog for improved fit. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Supabase Design System
Design resources for building consistent user experiences at Supabase.
Getting started
First, make a copy of .env.local.example and name it env.local. Then install any required packages and start the development server:
cd apps/design-system
pnpm i
pnpm dev:full
The dev:full command runs both the Next.js development server and Contentlayer concurrently, which is recommended for most development workflows.
Alternative commands
You can also run the development server and content watcher separately:
# Run only the Next.js development server
pnpm dev
# Run only the content watcher (in a separate terminal shell)
pnpm content:dev
Or run the development server from the root directory:
pnpm dev:design-system
To run both the development server and content watcher from the root directory, you can use:
# Run the development server
pnpm dev:design-system
# Run the content watcher (in a separate terminal shell)
pnpm --filter=design-system content:dev
Open http://localhost:3003 in your browser to see the result.
Watching for MDX changes
The dev:full command automatically watches for changes to MDX files with hot reload. If you're running the pnpm dev separately, you'll need to run pnpm content:dev in a separate terminal shell to watch for content changes.
Adding components
The design system references components rather than housing them. That’s an important distinction to make, as everything that follows here is about the documentation of components. You can add or edit components in one of these two places:
packages/ui: basic UI componentspackages/ui-patterns: components which are built using NPM libraries or amalgamations of components frompatterns/ui
There are several parts of this design system that need to be manually updated after components have been added or removed (from documentation). These include:
config/docs.ts: list of components in the sidebarcontent/docs: the actual component documentationregistry/examples.ts: list of example componentsregistry/fragments.ts: list of fragment componentsregistry/charts.ts: list of chart componentsregistry/default/example/*: the actual example components
You will need to rebuild the design system’s registry after making new additions:
cd apps/design-system
pnpm build:registry
