Alaister YoungandAlaister Young 2c76bb371b chore(studio): gate dead code with knip in CI (#49721)
Makes knip a CI gate for Studio so dead files and unused dependencies
fail the PR instead of piling up. Third PR in the stack, on top of
#49719 (dead code) and #49720 (unused deps), which get Studio to a clean
run.

**Changed:**
- knip `pnpx knip@~5.50.0` → root devDependency `knip@6.32.3`, `pnpm
knip` now runs it. The old `pnpx` form was actually broken: it resolved
knip's `typescript` peer to TS 7 and crashed with
`ts.getDefaultLibFilePath is not a function`. (6.33.0 is newer but
blocked by `minimumReleaseAge`.)
- `knip.jsonc` rewritten for v6 with a `workspaces["apps/studio"]`
block. Framework-convention files (`router.tsx`, `start.ts`,
`routes/**`, `compat/**`, `api/server.js`) are `entry` rather than
`ignore` — an ignored file's imports aren't traced, which is how
`ShellFallback.tsx` (only imported from `routes/__root.tsx`) was being
reported as dead. knip 6's Next.js plugin already covers
`instrumentation*.ts`, `proxy.ts`, `pages/**`; its tanstack-router
plugin only looks under `src/`, hence the manual entries. Narrow
`ignoreIssues` for graphql-codegen output and the `CONSTRAINT_TYPE`
enum; `ignoreDependencies` for the five implicit deps from #49720, each
with a comment; `ignoreBinaries: ["vercel"]`.
- `apps/studio/CLAUDE.md`: one bullet on the gate and where framework
files go.

**Added:**
- `.github/workflows/studio-knip.yml` — path-filtered to
`apps/studio/**` + knip/pnpm config, mirrors `studio-lint-ratchet.yml`'s
setup (no sparse checkout: knip needs every workspace's `package.json`
to resolve the graph). Runs `pnpm knip --workspace apps/studio
--reporter symbols --reporter github-actions` so findings show up as
inline PR annotations. ~5s locally.

Scope notes: the gate is Studio-only — the full-monorepo run still has
~400 dead files in `www`/`docs`/`blocks`, which is a separate effort.
`exclude: ["types", "exports"]` is kept, so unused exports aren't gated
yet, but `enumMembers`/`duplicates` are (they caught real things in
#49719).

## To test

- `pnpm knip --workspace apps/studio` exits 0 on this branch
- The `Studio Dead Code (knip)` workflow runs on this PR and is green
- Sanity-check the gate bites: add a throwaway
`apps/studio/lib/unused.ts`, run `pnpm knip --workspace apps/studio` →
reports it and exits 1

## Summary by CodeRabbit

* **CI**
* Added automated dead-code and unused-dependency checks for the Studio
workspace on relevant pushes and pull requests.
* Results appear in workflow summaries and as inline pull request
annotations.

* **Maintenance**
  * Improved analysis of framework-convention files and Studio code.
* Standardized the local code-quality check and updated its
configuration support.

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=
