18431efb25 fix(studio): TanStack post-merge fixes — Monaco loader, fonts, CSP (from #46424) (#47657)
Post-merge fixes for the TanStack Start migration (#46424) — things that
broke on the TanStack build as master evolved under the migration
branches. Kept on their own branch off master rather than piling onto
the E2E-matrix PR (#47119); all land on master and cascade up to S6 +
the big PR.

Common theme: a master PR changed something the Next pipeline handles
via `next/font` / `pages/_app.tsx` / `next.config.ts`, but the
hand-rolled TanStack equivalent (`routes/__root.tsx`,
`styles/fonts.css`, `vercel.ts`) wasn't updated to match — invisible on
the Next deploy, broken only on TanStack.

---

## 1. Monaco loader path (#47182)

#47182 re-nested the served Monaco assets from a flat
`public/monaco-editor/` layout into `public/monaco-editor/vs/` and
updated `pages/_app.tsx`, but `routes/__root.tsx` still pointed
`loader.config` at the old path, so `loader.js` 404'd and **no Monaco
editor mounted anywhere in the TanStack build**. Now mirrors the Next
config (`${origin}${BASE_PATH}/monaco-editor/vs`, window-guarded for
SSR). Was failing the whole `tanstack` E2E shard on #47119.

## 2. Inter + Manrope fonts (#47306)

#47306 renamed Tailwind's sans var `--font-custom` → `--font-sans` and
added `--font-heading` (Manrope), set via `next/font` on Next.
`fonts.css` still only set the now-ignored `--font-custom`, so the body
fell back to the theme's system chain (`Circular, custom-font,
Helvetica…`) at weight 450 — that's the "Inter weights look wrong".
Manrope was missing entirely.

- Wire `--font-sans` (Inter) + `--font-heading` (Manrope) to match
`next/font`.
- **Vendor all three families** (Inter, Manrope, Source Code Pro) via
`@font-face` so nothing depends on the Google Fonts CDN — matches
`next/font` self-hosting, and (see below) `font-src` doesn't allow
`fonts.gstatic.com` anyway.

Verified in-browser: computed `body` → `Inter`, headings → `Manrope`,
all loading from local `/assets/*.woff2`.

## 3. Security headers / CSP (next.config.ts `headers()`)

The Next build sets X-Frame-Options / X-Content-Type-Options / HSTS /
**Content-Security-Policy** / Referrer-Policy via `next.config.ts`. The
TanStack build never carried these over — `vercel.ts` only set
cache-control, so **the deployed TanStack dashboard shipped with no CSP
at all**.

The TanStack deploy serves a static shell (no server to attach headers),
so they go in the Vercel config:
- `security-headers.ts` — shared source of truth, reuses `getCSP()`,
env-gated exactly like next.config.
- `vercel.ts` — apply to every response (all base-path prefixes): full
`getCSP()` + HSTS on platform.
- `scripts/serve.js` — the non-platform set (`frame-ancestors 'none'`)
for the self-hosted server.

**Tested the policy in a real browser** (temporarily enforced it on the
TanStack build via /test-supabase-local): everything passed except one
real gap — `font-src` was missing `data:`, so GraphiQL's bundled Monaco
codicon font and Stripe's payment-element fonts (both data: URIs) were
blocked (37 violations on a cold load). Added `data:` to `font-src` in
`csp.ts` → violations drop to zero, SQL editor Monaco renders clean.
That gap affects the Next build too.

---

## 4. `node:path` import crashing `/project/[ref]/merge`

Found by a full-site click-through of the TanStack build (all product
areas, ongoing — see below). `useEdgeFunctionsDiff.ts` +
`EdgeFunctionsDiffPanel.tsx` did `import { basename } from 'path'` in
client code. Webpack (Next) polyfills `path` in the browser; Vite
externalizes it, so the whole `/merge` route crashed with "Module
\"path\" has been externalized for browser compatibility". Replaced the
two `basename` call sites with a string helper. Verified in-browser:
`/merge` renders.

## 5. URL shape — Next-style search-param semantics + shim fixes

The dashboard produced malformed URLs vs the Next build (strange query
params, trailing slashes, `##` hashes). Root cause + audit verified
empirically against `@tanstack/react-router@1.170.10`; all fixed with
unit tests and browser-verified:

- **`createRouter` used TanStack's default JSON search codec** —
`?flag=true` became `?flag=%22true%22` via links, repeated
`?filter=…&filter=…` collapsed into a JSON array (breaking
multi-filter/sort table-editor URLs and the account-page round-trip,
which double-encoded), and search values arrived as numbers/booleans
where the app expects strings. New `lib/router-search-params.ts`
(Next-style: strings in, strings out, repeated keys → string[]) wired
into the router.
- **Link shim** (`compat/next/link.tsx`): `URL.hash` includes the
leading `#` while TanStack's `hash` prop adds its own → every
`href="…#section"` navigated to `##section` (hash-scroll broke);
`Object.fromEntries(searchParams)` dropped repeated query params. Both
fixed.
- **Trailing slash injected before the query** on every `?`-only
relative navigation (`/auth/providers/?provider=…`): fixed in the compat
router (prefix current pathname) and via a custom nuqs adapter
(`lib/nuqs-tanstack-adapter.tsx`) replacing the stock tanstack-router
adapter, whose `navigate({ to: '?…' })` writes hit the same TanStack
behavior (123 files use nuqs).
- **Pathname-less `router.push({ query })` leaked path params** — Next
re-consumes `ref`/`id` from `query` into the path pattern; the shim
didn't, yielding
`/editor/17597?schema=public&ref=<ref>&id=17597&filter=…` from
table-editor filter/sort, linter panels, and advisor shortcuts. The shim
now defaults the pathname to the current route pattern and backfills
omitted params.
- **Redirects dropped query + hash** (Next's `redirects()` preserves
them): `__root.tsx` `matchRedirect` and `routes/index.tsx` now carry
incoming params/hash through (consumed rule params excluded,
destination's own params win). `/?next=new-project&projectName=zzz` →
`/new/new-project?projectName=zzz`; `/sql/quickstarts?template=x#frag` →
`/sql/examples?template=x#frag`.

Browser-verified post-fix: advisors `?preset=WARN`, providers
`?provider=Google`, `?schema=auth` — all clean (no `/?`, no leaks);
repeated `filter` params survive hydration; `=true` unquoted; single
`#`.

## 6. TanStack `navigate` corrupting query values (Logs Explorer SQL
newline loss)

TanStack router-core treats a query string embedded in `navigate({ to
})` as part of the *path*: `decodePath` percent-decodes it and
`sanitizePathSegment` strips control characters, silently deleting every
`%0A`. Logs Explorer's SQL (`s` param) lost its newlines on Run/reload —
`order by timestamp desc` / `limit 5` glued into `desclimit 5`, which
then failed the LIMIT lint. Pre-existing on the TanStack build (the
stock nuqs adapter had the same shape); Next unaffected.

Fixed by never embedding query strings in `to`: the nuqs adapter and the
compat `router.push`/`replace`/`prefetch` (plus the `next/navigation`
shim) now pass search as an object through the app codec
(`splitInternalUrl` hoisted to `lib/internal-url.ts`). Guard test drives
a real `createRouter` with multi-line SQL through both producers.
Browser-verified: newlines survive the full Run → reload → re-Run cycle.

## 7. Integration overview markdown never loaded (all integrations)

`MarkdownContent` used a template-literal dynamic import
(``import(`@/static-data/integrations/${id}/overview.md`)``) — webpack
builds a context module for that, Vite can't analyze it, so every
integration detail page threw `Failed to resolve module specifier` and
rendered no overview text. Fixed with an explicit lazy registry of
literal imports (`static-data/integrations/overviews.ts`, drift-guarded
by a test) plus an `mdRawLoader()` Vite plugin mirroring next.config's
turbopack raw-loader rule. Both runtimes keep working; md stays out of
the main bundle.

## 8. GraphiQL editor never mounted (`exports is not defined`)

Our `umdAmdShortCircuit()` Vite plugin (which disarms Monaco's global
AMD loader for deps like papaparse) rewrote `typeof define ===
'function' && define.amd` to `false` inside `monaco-editor`'s bundled
copy of marked — whose UMD relies on its own *local* `define` shim — so
the whole optimized monaco chunk failed to evaluate and GraphiQL's
editor pane stayed blank. The check now only short-circuits when
`define` is the global AMD loader. Browser-verified: all four GraphiQL
Monaco panes mount, queries execute. (Known follow-up: GraphiQL's Monaco
workers fall back to the main thread under Vite — functional, worker
wiring is Next-specific `setup-workers/webpack`.)

## 9. `@sentry/nextjs` bundling Next internals — built TanStack bundle
crashed (caught by E2E)

The E2E suite against the **built** TanStack bundle (not the dev server)
found lazy chunks like `table-editor-*.js` dead on arrival:
`@sentry/nextjs` (imported by ~25 client files) drags in
`next/dist/shared/lib/constants`, whose module scope evaluates
`process?.features?.typescript` — optional chaining doesn't guard an
undeclared `process` in the browser, so the whole chunk failed at load
with `ReferenceError: process is not defined`. Dev shims `process`,
which is why weeks of dev-server testing never saw it.

Fixed by aliasing `@sentry/nextjs` → `compat/sentry-nextjs.ts`
(re-exports `@sentry/react`, same deduped 10.59.0, plus explicit
stand-ins for the three Next-only APIs) in the Vite build only.
Verified: fresh build has zero Next-internals markers in any chunk;
table editor loads clean; full E2E suite run against the built bundle.

Note for the stack: `alaister/tanstack-start` / the E2E-matrix branch
already carried a different fix for the same crash (a `next/constants`
shim) that never made it to master — the cherry-pick onto those branches
keeps **both** (the shim covers any other transitive importer; the alias
keeps Next internals out of the client bundle entirely).

**Follow-up found while fixing:** Sentry is never *initialized* in the
TanStack runtime — `instrumentation-client.ts` /
`sentry.server.config.ts` are Next-convention files nothing imports
under TanStack, so `captureException` calls are silent no-ops. Needs an
`@sentry/react` init (+ `tanstackRouterBrowserTracingIntegration`) wired
into the TanStack client entry as its own PR.

## 10. GraphiQL Monaco workers + edge-function Deno typings (Vite-only
gaps)

- **GraphiQL's Monaco workers ran on the main thread** under Vite
("Could not create web worker(s)…" — `setup-workers/webpack`'s `new
URL(...)` form isn't rewritten by Vite). A `graphiqlViteWorkers()`
plugin resolves the import to graphiql's own `setup-workers/vite`
variant for client builds (SSR untouched, Next untouched); the
setup-workers chain is `optimizeDeps.exclude`d because the Rolldown
optimizer can't load `?worker` ids.
- **Edge-function editors silently lost their Deno typings** —
`AIEditor` loaded `public/deno/*.d.ts` via `/* @vite-ignore */` imports
that always failed at runtime under Vite. The `.md` raw loader is
generalized into `rawTextLoader` (exact-path allowlist for the two
typings files, served as virtual string modules so the dep scanner never
parses `.d.ts` syntax), and the imports are now static-analyzable
literals that both bundlers handle (turbopack's raw-loader rules match
them on the Next side).

## Split out for reviewability

App-level fixes that reproduce on the Next build too (DOM-nesting
hydration errors, the ghost deleted-snippet nav, the recurring pg-meta
`migrations` 400) moved to their own PR: #47667. Sentry initialization
for the TanStack runtime (captures were silent no-ops) is #47666,
stacked on this PR.

## Full-site test campaign

Drove every dashboard product area on the local TanStack build
(Playwright, human-style) hunting migration regressions:
redirects/404/catch-alls, org, account, project home/branches/merge,
table editor CRUD, SQL editor (Monaco/run/save/templates/AI), all
database pages, all auth pages, storage CRUD, edge functions + realtime,
logs/observability, advisors, settings, integrations hub incl. nested
routes, global UI (palette/connect/switchers/theme/fonts), and a
cross-cutting sweep (document titles, back/forward chain, hard-refresh
hydration on deep URLs, trailing-slash active state). Every failure
found is fixed above and re-verified in-browser; remaining console
quirks were cross-checked against the deployed Next build and are
pre-existing (tracked separately).

## To test

Most fixes are already browser-verified + covered by unit tests and the
self-hosted E2E suite; the last two landed after the final browser pass
and still need an in-browser check:

1. **GraphiQL Monaco workers** — restart the dev server (clear
`apps/studio/node_modules/.vite` once first — the optimizer cache may
hold a stale prebundle of the worker chain). Open
`/project/<ref>/integrations/graphiql/graphiql` with the console open:
the `Could not create web worker(s). Falling back to loading web worker
code in main thread` warning must be gone, and DevTools → Sources →
Threads shows the three workers (json, editor, graphql). Autocomplete in
the query editor stays responsive.
2. **Edge-function Deno typings** — `/project/<ref>/functions/new`: no
"Failed to load … typings" console error, and typing `Deno.` in the
editor offers typed completions (e.g. `Deno.env`).

Spot-checks for the rest (all previously verified):
- `/project/<ref>/merge` renders (no "Module path" crash).
- Multi-line SQL in Logs Explorer survives Run → reload (no `desclimit`
gluing, no LIMIT-lint false failure); `s` param keeps `%0A`.
- `/auth/providers` → open a provider → `?provider=…` with no trailing
slash before `?`; table-editor filter/sort URLs carry no leaked
`ref`/`id` params; `/?next=new-project&projectName=x` lands on
`/new/new-project?projectName=x`.
- Integration detail pages (cron/queues/vault/data_api) show their
overview prose; GraphiQL query editor mounts.
- Built bundle (`MODE=test vite build` + `start:tanstack`): table editor
loads with no `process is not defined`.
- `curl -sI` any page on a platform deploy: `X-Content-Type-Options:
nosniff` (was the invalid `no-sniff`).

### Review feedback: non-prod favicon (Joshen)

The TanStack `__root.tsx` hardcoded the prod favicon; local + hosted
staging now use the white staging favicon (`/favicon/staging`), matching
what `pages/_app.tsx` passes to `MetaFaviconsPagesRouter` for non-prod.
Rather than pull the pages-router component into the TanStack head, it
reuses the same synchronous `NEXT_PUBLIC_ENVIRONMENT` signal the file
already uses for `IS_DEV_TOOLBAR_ENABLED` (the `head()` route option
isn't a React component, so it can't run `_app`'s async CLI check — but
the env signal covers the reported local/staging case).

Supabase Studio E2E Tests

Set up

Prerequisites

For Self-Hosted Tests

  • Nothing is required, running with IS_PLATFORM=false should run the tests locally with a self hosted docker container

For Platform Tests

  1. Create a platform account - You can authenticate using either:
    • Email and password
    • GitHub OAuth (requires TOTP 2FA)
  2. Create an organization on the platform, this can be done if run locally through mise fullstack
  3. Generate a Personal Access Token (PAT) for API access
  4. Configure the environment variables below (see Authentication section for details on email vs GitHub auth)

Configure Environment

Choose the appropriate example file based on your testing scenario:

For self-hosted tests:

cp .env.local.self-hosted.example .env.local

For platform tests with email authentication:

cp .env.local.email.example .env.local

For platform tests with GitHub authentication:

cp .env.local.github.example .env.local

Edit .env.local and set the appropriate values based on your test environment (see Environment Variables section below).

Install the playwright browser

⚠️ This should be done in the e2e/studio directory

cd e2e/studio

pnpm exec playwright install

Environment Variables

Configure your tests by setting the following environment variables in .env.local. We have examples of what required on self hosted and platform:

Core Configuration

  • STUDIO_URL: The URL where Studio is running (default: http://localhost:8082)
  • API_URL: The Supabase API endpoint (default: https://localhost:8080)
  • IS_PLATFORM: Set to true for platform tests, false for self-hosted (default: false)
    • When true: Tests run serially (1 worker) due to API rate limits
    • When false: Tests run in parallel (5 workers)

Authentication (Required for Platform Tests)

⚠️ Before running platform tests, you must create an account and organization on the platform you're testing.

Authentication is automatically enabled when either email/password OR GitHub credentials are configured.

Email Authentication
  • EMAIL: Your platform account email
  • PASSWORD: Your platform account password
  • PROJECT_REF: Project reference (optional, will be auto-created if not provided)

When both EMAIL and PASSWORD are set, the tests will authenticate using email/password. HCaptcha is mocked during test setup. Note this only works on local and staging environments

GitHub Authentication
  • GITHUB_USER: Your GitHub username
  • GITHUB_PASS: Your GitHub password
  • GITHUB_TOTP: Your GitHub TOTP secret for 2FA (required, as GitHub enforces 2FA)

When GITHUB_USER, GITHUB_PASS, and GITHUB_TOTP are all set, the tests will authenticate using GitHub OAuth with TOTP-based 2FA. The authentication flow handles:

  • Clicking "Sign In with GitHub" button
  • Filling GitHub credentials
  • Generating and submitting TOTP codes
  • Handling GitHub authorization prompts
  • Automatic retry on failure (up to 3 attempts)

Getting your GitHub TOTP secret: When setting up 2FA on GitHub, you'll see a QR code. Click "enter this text code instead" to reveal the secret key. This is the value to use for GITHUB_TOTP.

Platform-Specific Variables (Required when IS_PLATFORM=true)

  • ORG_SLUG: Organization slug (default: default)
  • SUPA_REGION: Supabase region (default: us-east-1)
  • SUPA_PAT: Personal Access Token for API authentication (default: test)
  • BRANCH_NAME: Name for the test branch/project (default: e2e-test-local)

Optional Variables

  • OPENAI_API_KEY: Required for the AI Assistant test (assistant.spec.ts). Without this variable, the assistant test will be skipped.
  • VERCEL_AUTOMATION_BYPASS_SELFHOSTED_STUDIO: Bypass token for Vercel protection (default: false)

Setup Commands Based on Configuration

The test setup automatically runs different commands based on your environment:

  • Platform + Localhost (IS_PLATFORM=true and STUDIO_URL=localhost): Runs pnpm run e2e:setup:platform
  • Platform + Remote (IS_PLATFORM=true and remote STUDIO_URL): No web server setup
  • Self-hosted (IS_PLATFORM=false): Runs pnpm run e2e:setup:selfhosted

Running the tests

Check the package.json for the available commands and environments.

pnpm run e2e

With Playwright UI:

pnpm run e2e -- --ui

Tips for development

  • Read Playwright Best Practices
  • Use pnpm run e2e -- --ui to get the playwright UI.
  • Add the tests in examples/examples.ts to Cursor as context.
  • Add messages to expect statements to make them easier to debug.

Example:

await expect(page.getByRole('heading', { name: 'Logs', exact: true }), {
  message: 'Logs heading should be visible',
}).toBeVisible()
  • Use the test utility instead of playwrights test.
import { test } from '../utils/test'
  • Use the PWDEBUG environment variable to debug the tests.
PWDEBUG=1 pnpm run e2e -- --ui

What should I test?

  • Can the feature be navigated to?
  • Does the feature load correctly?
  • Can you do the actions (filtering, sorting, opening dialogs, etc)?

API Mocks

Read here: https://playwright.dev/docs/mock#mock-api-requests

Example:

await page.route(`*/**/logs.all*`, async (route) => {
  await route.fulfill({ body: JSON.stringify(mockAPILogs) })
})
