docs(middleware): site-wide HTTP Basic Auth example - #3709
Conversation
Document the built-in gate first (VERYFRONT_BASIC_USER/PASS operator env vars or security.auth.basic in veryfront.config — constant-time comparison, orchestrator probe paths stay reachable) and then a custom root-middleware variant for cases the built-in does not cover, reading credentials from c.env with a process.env fallback and failing closed when none are configured. Both variants verified against a running dev server: 401 for missing, wrong, and malformed credentials; 200 with the demo pair; /healthz and /readyz exempt from the built-in gate.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe middleware guide now documents built-in and custom site-wide HTTP Basic Auth. It covers credential loading, header validation, malformed requests, unauthorized responses, curl verification, and platform bypass behavior. ChangesBasic Auth documentation

In `@docs/guides/middleware.md`:
- Around line 259-283: Update the “Custom Basic Auth middleware” documentation
to state that project-supplied middleware is supported only in local, dedicated,
or self-hosted deployments; clarify that shared hosted deployments reject custom
middleware and should use the built-in authentication gate instead. Apply the
same scope clarification to the related guidance near the later middleware
example.
- Around line 286-287: Update the authorization header check to compare the
authentication scheme case-insensitively, while preserving the existing
rejection of non-Basic schemes and the current unauthorized response.
- Around line 268-273: Update unauthorized() credential handling to decode the
Base64-decoded bytes as UTF-8 with TextDecoder using fatal validation before
comparing credentials, preserving the existing rejection behavior for invalid
encoding; alternatively, explicitly document that credentials are ASCII-only.

The public-docs validator rejects em dashes; docs:public:check now passes across all 123 files.
- Read the config secret through getEnv from veryfront: the hosted declarative config evaluator rejects process.env as a forbidden capability, and an unset password fails config validation (safe failure). - Accept a case-insensitive authentication scheme per RFC 7235. - Decode the base64 credential bytes as UTF-8 (fatal) before comparing, so non-ASCII credentials work as the charset="UTF-8" challenge promises. - Distinguish the root middleware.ts file, which the shared hosted runtime compiles and runs, from the middleware.custom config option, which hosted runtimes reject. Revised example re-verified against a running dev server: 401 for missing, wrong, and malformed credentials; 200 for a UTF-8 username through both 'Basic' and 'basic' schemes.

Description
Adds a worked site-wide HTTP Basic Auth section to the middleware guide, in two parts:
VERYFRONT_BASIC_USER/VERYFRONT_BASIC_PASSoperator env vars, orsecurity.auth.basicinveryfront.config. This was previously undocumented. It compares credentials in constant time and keeps the orchestrator's probe paths (/healthz,/readyz) reachable.MiddlewareHandler,c.request), reading credentials fromc.envwith aprocess.envfallback (the shared hosted runtime delivers project env viac.env; local dev and dedicated servers expose it asprocess.env— verified empirically,c.envis empty in local dev), and failing closed when no credentials are configured.Both variants were verified against a running dev server before documenting: 401 for missing/wrong/malformed credentials, 200 with the demo pair, and
/healthz//readyzexempt from the built-in gate while the site 401s. Credentials in all examples are neutral placeholders (demo-user/demo-pass).Type of Change
