Alaister YoungandAlaister Young 3bac7165bd chore(studio): move the TanStack Start deploy onto Nitro (#50030)
Moves the Studio TanStack Start build off the hand-rolled Vercel setup
(an `api/server.js` function shim, rewrites in `vercel.ts`, a custom
`?dpl=` skew-protection Vite plugin, and `scripts/serve.js` for
self-hosted) and onto Nitro, which TanStack Start documents as its
deployment path. Documents are served from the static SPA shell on the
CDN; only `/api/*` and `/_serverFn/*` invoke the function.

**Removed:**
- `api/server.js`, `scripts/serve.js`, `scripts/smoke-server.mjs`
- The `skewProtectionDpl` Vite plugin, `renderBuiltUrl`, and the
`vite:preloadError` reload backstop in `router.tsx` (TanStack Router
already reloads once on a failed lazy import)
- Rewrites, `functions`, `outputDirectory`, and `cleanUrls` from
`vercel.ts` (redirects and headers stay)
- `magic-string` and `@jridgewell/remapping` devDependencies, the
`preview` script

**Added:**
- `nitro` plugin in `vite.config.ts`. Preset is auto-detected:
`.vercel/output` on Vercel, a self-contained node server in `.output`
everywhere else. `vercel.immutableStaticFiles` puts hashed chunks under
`/_vercel/immutable/` so tabs opened before a redeploy keep loading
their chunks; `functions.maxDuration: 300` carries over the old function
timeout
- `scripts/vercel-spa-routes.ts`: Nitro module that rewrites the
generated Build Output routes (documents -> `_shell.html`, allow-list ->
`__server`, missing chunk -> 404, base-path prefixes), with a unit test
- `server.ts`: TanStack Start server entry that initializes Sentry
before the route tree loads and wraps the handler with
`wrapFetchWithSentry`

**Changed:**
- `start:tanstack` runs `.output/server/index.mjs` directly with Node's
`--env-file-if-exists` for the `.env` cascade. Node doesn't expand
`$VAR` references, so `scripts/generateLocalEnv.js` now writes literal
values into `.env.test`
- Dockerfile's TanStack stage copies `.output` instead of running `pnpm
deploy`; the `server.js` shim loads `.env` and imports the Nitro server
- `NEXT_PUBLIC_BASE_PATH` (the platform's `/dashboard`) only sets the
router basepath; Vite's `base` stays at the root so chunks can use the
immutable store. The routes module emits prefixed rules for
`/dashboard/api/*` and `/dashboard/_serverFn/*` and rewrites `public/`
files requested under the prefix back to the root
- Self-hosted security headers come from a Nitro `routeRules` entry; on
Vercel they stay in `vercel.ts`
- `tslib` is inlined for the build only: Nitro's dev runner has no
interop for its CJS wrapper
- Monaco's worker chunks follow the client assets dir so they land in
the immutable store too

Verified on the `studio-staging` preview (`STUDIO_FRAMEWORK=tanstack` is
scoped to this branch there): documents come back as the static shell,
`/dashboard/api/*` hits the function, `public/` files resolve under the
prefix, a missing immutable chunk 404s. Across two deployments of this
branch, the older deployment's chunks still load from the immutable
store and requests carrying its `__vdpl` cookie are answered by that
deployment. Self-hosted path covered by the TanStack E2E job and the
Docker build job.

## To test

- On the `studio-staging` preview: `/dashboard/project/<ref>` should
show `content-disposition: inline; filename="_shell.html"` and a
single-region `x-vercel-id`; `/dashboard/api/get-utc-time` a two-region
id
- Sign in and click through a few pages, including one that opens Monaco
(SQL editor) so the worker chunks load
- After the next deploy, a tab left open on the previous one should
still navigate (lazy chunks) and call the API without errors
- Self-hosted: `STUDIO_FRAMEWORK=tanstack pnpm --filter studio build &&
pnpm --filter studio start`, then check `/api/platform/profile` and that
responses carry the security headers

## Summary by CodeRabbit

* **New Features**
* Production TanStack deployments now run on Nitro’s self-contained
server output.
* Vercel routing serves static pages first while directing API and
server-function requests appropriately.
* Server-function requests can include deployment identification for
consistent handling.
* Local environment generation now writes resolved configuration values.

* **Bug Fixes**
  * Improved handling of missing static assets and SPA fallback routing.
* Server-side error monitoring now captures request errors in the new
runtime.

* **Refactor**
* Replaced the legacy production server and smoke-test workflow with
Nitro-based startup.
  * Removed automatic reload handling for stale client assets.

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=
