Danny White facc2df09e chore(design-system): generate and ignore registry output (#49290)
## What kind of change does this PR introduce?

Chore. Stops committing generated design-system registry output
([DEPR-647](https://linear.app/supabase/issue/DEPR-647/generate-and-ignore-design-system-registry-output)).

## What is the current behavior?

`apps/design-system/__registry__` is build output from `registry/`, but
the chart snapshots and index are committed. That makes reviews noisy,
and a forgotten `build:registry` leaves `master` out of date until
someone else regenerates it.

## What is the new behavior?

`pnpm dev` and `pnpm typecheck` generate `__registry__` automatically.
The directory is gitignored, and the previously tracked snapshots are
removed. `pnpm build` still generates it as before.

## To test

- From the repo root, run `pnpm --filter=design-system
generate:registry` and confirm
`apps/design-system/__registry__/index.tsx` is created locally and is
untracked.
- Run `pnpm dev:design-system`, open
[http://localhost:3003](http://localhost:3003), and open any component
docs page with a live preview (for example Charts). Previews and source
panels should still load.

## Summary by CodeRabbit

* **Documentation**
* Clarified when the component registry is generated and how to
regenerate it.
* Expanded component documentation guidance, including content sources
and generated-file editing restrictions.

* **Chores**
* Improved registry generation across development, type checking,
builds, and cleanup.
* Generated registry files are now excluded from version control and
linting.
* Improved reliability when creating and refreshing generated registry
files.

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

The dev command generates __registry__, then runs the Next.js development server and Contentlayer together. That is the recommended workflow.

Alternative commands

You can also run the development server and content watcher separately. Generate the registry first, because dev:next and dev:content do not:

pnpm generate:registry

# Run only the Next.js development server
pnpm dev:next

# Run only the content watcher (in a separate terminal shell)
pnpm dev:content

From the repo root, pnpm dev:design-system runs the same dev script, so it also generates __registry__. If you split the watchers from the root, generate first:

pnpm --filter=design-system generate:registry
pnpm --filter=design-system dev:next
pnpm --filter=design-system dev:content

Open http://localhost:3003 in your browser to see the result.

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:

After you add or remove documented components, update these source files:

  • config/docs.ts: list of components in the sidebar
  • content/docs: the component documentation
  • registry/examples.ts: example components
  • registry/fragments.ts: fragment components
  • registry/charts.ts: chart components
  • registry/copy-writing.ts: copywriting examples
  • registry/default/example/*: the example component implementations
  • registry/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 generate:registry
