Anthony Lio b13d6c2878 feat(chore): add a lint ratchet for shadcn rules (#51014)
## 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`

## Review instructions

1. run `pnpm --filter ./apps/www run lint:ratchet`
2. add `p-[13px]` to a `className` in any www component and run it
again. it fails with `shadcn/no-arbitrary-values` and the file name with
`(+1)`
3. revert change
4. run `pnpm --filter eslint-config-supabase test` and see 6 tests pass
5. in ci, check `Ratchet studio lint checks` and the `ratchet (<app>)`
jobs for the apps this pr touches

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
