## Problem shadcn lint rules has been soft landed in #50676 and are now on as warnings in every app, but nothing stops a PR from adding new violations linear: FE-4473 ## Solution - moved the ratchet script and its tests from `apps/studio/scripts` to `packages/eslint-config-supabase` so every app runs one copy - added a shared rule list, `packages/eslint-config-supabase/ratchet-rules.json` with the shadcn rules - www, docs, design-system, ui-library and learn get `lint-ratchet.yml` with one job per changed app (triggered by the app, `packages/**` or the lockfile) + a weekly `lint-ratchet-decrease.yml` (as for studio ratchet) - package tests run in `eslint-config-supabase-tests.yml` <!-- ## Preview links If relevant, include links to changed pages for easy review access.

Supabase Design System
Design resources for building consistent user experiences at Supabase.
Getting started
From the repo root:
# Copy local env vars (sets NEXT_PUBLIC_BASE_PATH for asset URLs)
cp apps/design-system/.env.local.example apps/design-system/.env.local
# Move into the design-system app
cd apps/design-system
# Install dependencies
pnpm i
# Build the registry and Velite content, then start the dev servers
pnpm dev
Or from apps/design-system:
# Copy local env vars (sets NEXT_PUBLIC_BASE_PATH for asset URLs)
cp .env.local.example .env.local
# Install dependencies
pnpm i
# Build the registry and Velite content, then start the dev servers
pnpm dev
The dev command builds the registry and Velite content, then runs the Next.js dev server and Velite watcher in parallel.
Open http://localhost:3003/design-system in your browser to see the result.
Doc pages load compiled MDX from .velite/codes/*.json per document. Metadata lives in the smaller allDocs.json index (~367KB instead of ~27MB), so content edits only reload the changed doc's code.
Alternative commands
You can also run the development server and content watcher separately. Build the registry and content first, because dev:next and dev:content do not:
pnpm build:registry
pnpm build:content
# Run only the Next.js development server
pnpm dev:next
# Run only the Velite content watcher (in a separate terminal shell)
pnpm dev:content
From the repo root, pnpm dev:design-system runs the same dev script. If you split the watchers from the root, build first:
pnpm --filter=design-system build:registry
pnpm --filter=design-system build:content
pnpm --filter=design-system dev:next
pnpm --filter=design-system dev:content
Watching for MDX changes
The dev command watches MDX files and hot-reloads them. If you are running pnpm dev:next on its own, also run pnpm dev:content in another terminal.
Adding components
The design system references components rather than housing them. That distinction matters: everything below is about documenting components, not implementing them. Add or edit the components themselves in one of these two places:
packages/ui: basic UI componentspackages/ui-patterns: components built from libraries or frompackages/ui
After you add or remove documented components, update these source files:
config/docs.ts: list of components in the sidebarcontent/docs: the component documentationregistry/examples.ts: example componentsregistry/fragments.ts: fragment componentsregistry/charts.ts: chart componentsregistry/copy-writing.ts: copywriting examplesregistry/default/example/*: the example component implementationsregistry/default/block/*: chart block implementations, when you add a chart
Do not edit __registry__. pnpm dev, pnpm typecheck, and pnpm build generate it from the files above, and it is gitignored. If you add registry entries while the app is already running, regenerate it:
cd apps/design-system
pnpm build:registry
