cd34776be1 fix(studio): honor MAINTENANCE_MODE in the TanStack runtime (#48616)
## What kind of change does this PR introduce?

Bug fix.

## What is the current behavior?

Fixes #48559 (diagnosed by @ayaangazali)

The TanStack Start runtime never applies maintenance mode.

`matchRedirect` in `apps/studio/redirects.shared.ts` takes a
`maintenanceMode`
flag, and both other consumers wire it from the environment:

- `apps/studio/next.config.ts` — `process.env.MAINTENANCE_MODE ===
'true'`
- `apps/studio/vercel.ts` — same

The TanStack call site in `apps/studio/routes/__root.tsx` passed only
`pathname`, `search`, `isPlatform` and `hash`, so `maintenanceMode` fell
back
to its `= false` default. With `MAINTENANCE_MODE=true` on a TanStack
deploy
that produced two wrong behaviors:

1. No path redirected to `/maintenance` — the app served normally during
   maintenance.
2. Because the flag read false, the "not in maintenance" branch still
applied
and sent `/maintenance` → `/`, making `routes/maintenance.tsx`
unreachable.

Mainly affects self-hosted / Node-server TanStack deploys; the platform
deploy
is covered by the Vercel edge layer, which does wire the flag.

## What is the new behavior?

The TanStack runtime honors `MAINTENANCE_MODE` the same way the Next
runtime
and the edge config do.

**Design note.** The issue asked whether this needs a new `NEXT_PUBLIC_`
variable or server-side plumbing, since both would change deployment
configuration for self-hosters. Neither is needed. `MAINTENANCE_MODE` is
already a *build-time* variable in both existing consumers — Next bakes
`redirects()` into `routes-manifest.json` during `next build`, and
`vercel.ts`
reads it while emitting `vercel.json`. Toggling maintenance has always
required
a rebuild, never just a server restart. And `vite.config.ts` isn't bound
by
Next's "only `NEXT_PUBLIC_`" rule: it controls `define` directly, and
already
re-exposes unprefixed `VERCEL_*` vars the same way. So the existing
unprefixed
variable is inlined at build time, giving exact parity with **no new env
var
and no config change for self-hosters**.

Three changes:

1. `vite.config.ts` — inline `process.env.MAINTENANCE_MODE` into the
bundle.
Falls back to `''` rather than being left undefined, so the browser
bundle
never ends up with a bare `process.env` reference (the failure mode the
file
   already guards against for the Sentry vars).
2. `routes/__root.tsx` — read it into `IS_MAINTENANCE_MODE` and pass it
to
   `matchRedirect`.
3. `redirects.shared.test.ts` — 4 tests for the maintenance branches of
   `matchRedirect`, which had no coverage at all.

`turbo.jsonc` already lists `MAINTENANCE_MODE` under the build task's
`env`, so
cache invalidation is correct for the Vite build too — no change needed.
No
README or docs change either, since the env contract is unchanged.

## Additional context

Verified end-to-end, not just by unit test.

**Browser repro** — built SPA served via `scripts/serve.js`, driven in
headless
Chromium:

| `MAINTENANCE_MODE=true` | lands on | |
| --- | --- | --- |
| `/project/default` | `/maintenance` | fixes behavior 1 |
| `/` | `/maintenance` | |
| `/maintenance` | `/maintenance` | fixes behavior 2 |

The maintenance page renders real content ("Under Maintenance — We are
currently improving our services…"), so the route is genuinely
reachable.

| control, var unset | lands on | |
| --- | --- | --- |
| `/project/default` | `/project/default` | normal routing intact |
| `/` | `/project/default` | root redirect intact |
| `/maintenance` | `/project/default` | correctly bounces away |

**Bundle inspection** — the flag compiles to a literal `true` with the
variable
set and `false` without it, confirming the define reaches the client.

**Shell prerender** — checked explicitly, since the maintenance-on rule
is a
catch-all. Builds with `MAINTENANCE_MODE=true` prerender the SPA shell
and pass
the post-build smoke test; the prerenderer crawls `/` and the root
`beforeLoad`
redirect does not fire during shell generation, so no guard is required.

**Checks** — 20 unit tests pass, typecheck 8/8, ESLint ratchet passes,
Prettier
clean.

7fd7ace118 feat(studio): add Infrastructure replica detail route and redirects (#49045)
## What kind of change does this PR introduce?

Feature. Stack 3 of 5 for
[PIPE-1007](https://linear.app/supabase/issue/PIPE-1007/move-read-replicas-out-of-replication-into-infrastructure).

## What is the current behavior?

Replica detail lives at `/database/replication/replica/:id`.

## What is the new behavior?

Detail moves to `/settings/infrastructure/replica/:id`. Old URLs
redirect. List and diagram View/Manage replica links follow.

## Additional context

Stacked on [#49044](https://github.com/supabase/supabase/pull/49044).
Please review, but do not merge. Merge 2→5 in succession once they are
all reviewed, so users never sit on a split create/list vs detail path.

Replication still lists and creates replicas until
[#49046](https://github.com/supabase/supabase/pull/49046).

## To test

`infrastructure:read_replicas` is an enabled-feature, on by default.
There is no Feature Preview or ConfigCat switch. You should already see
the Infrastructure Read replicas section. If you do not, your profile
lists `infrastructure:read_replicas` in `disabled_features`.

From
[Infrastructure](https://studio-staging-git-danny-pipe-1007-03-detail-redirects-supabase.vercel.app/dashboard/project/_/settings/infrastructure),
open View replica on a row. Confirm you land on
`/settings/infrastructure/replica/:id`. If you have an old bookmark,
`/database/replication/replica/:id` should redirect there.

ad203ae277 Merge compute and disk into Infrastructure (#48370)
## Summary

This is the final step in merging compute and disk with infrastructure
to become a single place to manage everything. This moves everything
we've done in compute and disk over to infrastructure along with
redirects.

- Makes Infrastructure canonical for the completed compute and disk
configuration and usage charts.
- Moves Service Versions to General Project Settings.
- Removes the legacy Infrastructure activity implementation and
constants.
- Updates settings navigation, shortcuts, banners, billing links,
warning CTAs, usage pages, support suggestions, and other internal entry
points.
- Adds the permanent `/settings/compute-and-disk` redirect, removes its
Next and TanStack routes, regenerates the route tree, and updates the
migration checklist.
- Preserves query parameters and legacy metric anchors, including
`#cpu`.

## Stack

1. #48368
2. #48369
3. #48370 (this PR)

## How to test

1. Check out `chore/infra-compute-3-cutover`.
2. Test the Next implementation with `pnpm dev:studio`, then stop it and
test TanStack with `STUDIO_FRAMEWORK=tanstack pnpm dev:studio`.
3. In each implementation, open
`/project/<ref>/settings/infrastructure`. Confirm the page contains the
usage charts and the Scaling, Compute, Disk, and Advanced configuration
sections.
4. Open `/project/<ref>/settings/general`. Confirm Service Versions
appears there with its existing name, content, and styling, and no
longer appears on Infrastructure.
5. Open `/project/<ref>/settings/compute-and-disk?upgrade=micro#disk`.
Confirm it permanently redirects to
`/project/<ref>/settings/infrastructure?upgrade=micro#disk`, preserving
the query string and hash.
6. Confirm the settings menu exposes Infrastructure and no longer
exposes Compute and Disk. Repeat with platform and self-hosted settings.
7. Follow representative entry points from billing usage, resource
warning CTAs, upgrade banners, shortcuts, and support suggestions.
Confirm they land on Infrastructure and preserve any query parameters or
metric anchors such as `#cpu`.
8. Smoke-test compute and disk updates from Infrastructure, including
validation, the sticky review footer, and warning/critical chart states.

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).
