📝 Walkthrough

Walkthrough

The documentation site adds @supabase/middleware as a v1 SDK reference. It registers navigation and metadata, adds generated-reference configuration and installation content, downloads the middleware specification, and includes the generated reference in full search indexing.

Changes

Middleware SDK reference

Layer / File(s) Summary
Reference registration and navigation
apps/docs/components/Navigation/NavigationMenu/*, apps/docs/content/navigation.references.ts, apps/docs/layouts/MainSkeleton.tsx
The Middleware SDK receives v1 reference metadata, a /reference/middleware menu entry, and a Middleware Reference v1.0 section label.
Reference pipeline and content
apps/docs/features/docs/Reference.constants.ts, apps/docs/internals/generate-reference-markdown.ts, apps/docs/package.json, apps/docs/spec/*, apps/docs/docs/ref/middleware/*
The new reference pipeline downloads middleware.json, processes middleware v1 configuration, and publishes installation and introduction pages.
Middleware reference search indexing
apps/docs/scripts/search/sources/index.ts
Full indexing loads generated Middleware TypeScript reference content and adds it to the aggregated search sources.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 3e425

The documentation build can leave an invalid specification file after a failed download, preventing automatic retry and potentially blocking regeneration. The PR is otherwise mergeable with explicit owner awareness or follow-up for this bounded build risk.

In `@apps/docs/spec/Makefile`:
- Line 58: Update the middleware spec fetch in the Makefile so the spec is
written atomically instead of redirecting directly to middleware.json. Download
with curl to a temporary file first, then move it into the
reference/middleware/v1/middleware.json path only after the download succeeds,
keeping the existing fetch target behavior intact.

In `@apps/docs/spec/reference/middleware/v1/partials/introduction.mdx`:
- Line 26: Update the opening sentence in the introduction partial so the
subject-verb agreement is correct by changing the middleware statement to use
the singular verb form. Keep the rest of the `getEnv` explanation unchanged.

Apply the same fix in `@apps/docs/docs/ref/middleware/introduction.mdx` at line
26: The same wording error appears in the documentation copy.

LGTM 🚀 except for this text from the reference that feels difficult to parse, maybe a bit too emdash happy, and seems overly wordy:

Maybe apply some judicious editing? (Reference content should be sparse, to the point, and well structured.)


`/review-the-docs verdict: Approve with nits

Check Result
Pipeline wiring (generate-reference-markdown.ts, Reference.constants.ts, Makefile, package.json, search sources) Matches the server-v1 precedent field-for-field; build-reference-content.ts is fully generic/directory-driven, no extra changes needed there
Nav wiring (NavigationMenu.constants.ts, .tsx, MainSkeleton.tsx, navigation.references.ts) Consistent with reference_server_v1 naming/level conventions; reuses the registered reference-javascript icon (same as server does)
End-to-end build Ran pnpm run codegen:references:new — pulled the live https://supabase.github.io/middleware/spec.json and generated 5 files, 23 functions across 4 categories matching config.json's categoryOrder
Reference markdown export pnpm build:reference-markdown → generated public/markdown/reference/middleware.md correctly, with working [@supabase/server](/docs/reference/server/introduction) cross-link (target file confirmed to exist, link format matches existing docs/ref/** precedent)
Typecheck pnpm typecheck --filter=docs passes
Prettier All changed files pass prettier --check
CI All checks green (typecheck, format, E2E, Docs E2E, CodeRabbit)

Verified:

  • The docs/ref/middleware/ MDX and spec/reference/middleware/v1/partials/ copies are intentionally duplicated (same non-syncing pattern as server), not a PR-introduced bug.
  • No dedicated "Alpha" nav badge exists in the codebase — MenuItem only supports boolean community/new props rendering fixed "Community"/"New" badges (GlobalNavigationMenu.tsx:182-183). Any nav-level alpha badge would be new code, not reuse of an existing mechanism.
  • No existing guide section for server-style SDKs; content/guides/ has no analogous bucket, so keeping concept material in the reference introduction is consistent with the only precedent that exists (server does the same).

Nits:

  • CodeRabbit's grammar catch is still unfixed in both copies: "Middleware read configuration through getEnv" → should be "Middleware reads configuration" (subject-verb agreement). Confirmed present in the built middleware.md output too.
    • apps/docs/spec/reference/middleware/v1/partials/introduction.mdx#L26
    • apps/docs/docs/ref/middleware/introduction.mdx#L26
  • CodeRabbit's Makefile atomic-write suggestion for download.middleware.v1 is not a regression — it mirrors download.server.v1 exactly, which already writes non-atomically. Fine to skip as out of scope.
