Strip API Surface

Strip API Surface

Strip is a Fiber HTTP server that renders Templ pages and serves HTMX-style JSON fragments. It has no direct DB writes for domain entities — every business read or mutation is forwarded to sirloin over gRPC.

Topology

flowchart LR
  Browser -->|HTTPS| Strip[Strip Fiber<br/>:8080]
  Strip -->|Clerk SDK / cookie| Clerk[(Clerk)]
  Strip -->|gRPC| Sirloin[(sirloin StripService<br/>v5)]

See apps/strip/cmd/app/main.go startFiberServer (line 330+).

Middleware Stack (in order)

Registered in cmd/app/main.go:

1. requestid.New() — request ID for trace correlation.
2. recover.New(EnableStackTrace: true) — panic recovery, returns 500.
3. helmetMiddlewareForStage — security headers (CSP varies by stage).
4. limiter.New (globalRateLimitMax) — IP-keyed global rate limit. Asset paths (/assets, /assets/...) are skipped via shouldSkipGlobalRateLimit.
5. compress.New — gzip/brotli on dynamic responses.
6. Static file serving for /assets.

A stricter authLimiter is layered onto /login, /auth/refresh, and /auth/clerk/callback.

Auth Surface

Auth is enforced by two middlewares (apps/strip/internal/app/middleware/):

• AuthMiddleware.RequireAuth — verifies a Clerk session cookie or __session token; populates c.Locals("userId" | "userEmail" | "sessionToken").
• AuthorizationMiddleware.RequirePermission(perm) — RBAC, fails with 403. HTMX requests get a JSON body + HX-Reswap: none, otherwise the forbidden Templ page.

Two dev-only bypass paths exist and emit SECURITY WARNING logs:

• X-Auth-Bypass: <uuid> header (or ?auth=<uuid>) matching STRIP_AUTH_BYPASS_UUID.
• Stage == development with clerkService == nil.

Permission catalog (internal/app/authorization/authorization.go): view:dashboard, view:users, manage:credits, view:characters, create:character, update:character, delete:character, manage:nsfw, manage:approved_celebrity, view:media, delete:media, view:audit_logs, view:dataset, view:examples, view:payments, create:users, manage:roles, manage:admins.

Templ Pages

Templ files render every protected page above. They live under apps/strip/internal/app/strip/templates/ and are compiled by templ generate into *_templ.go siblings. The strip Fiber handlers call templates.<Page>(...).Render(ctx, c) rather than c.Render. See services/strip-datatable/ and services/strip-filters/ for the shared render primitives.

Downstream gRPC Calls

Strip embeds the generated client at apps/strip/internal/pkg/pb/sirloin/v5/. The proto contract is proto/sirloin/v5/strip.proto, service sirloin.v5.StripService. RPCs called by handlers include:

• StripListUsers, StripUpdateUser
• StripListCharacters, StripCreateCharacter, StripUpdateCharacter, StripDeleteCharacter, StripBypassCharacterOnboardingChecks
• StripListMedia, StripFailMedia
• StripListPopularExamples, StripListPopularCategories
• StripListDatasetImages
• StripLogAudit, StripListAuditLogs, StripGetAuditLog
• StripGetUserRole, StripListUserRoles, StripSetUserRole, StripDeleteUserRole (proto/sirloin/v5/strip.proto:33-36)
• StripCreateClerkUser (proto/sirloin/v5/strip.proto:39)
• StripFoxy360CreateThread, StripFoxy360SendMessage, StripFoxy360GetRun, StripFoxy360ListMessages, StripFoxy360ListArtifacts (proto/sirloin/v5/strip.proto:42-46)
• StripGetDashboardStats, StripGetSchema, StripRunReadonlyQuery (proto/sirloin/v5/strip.proto:28-30)
• StripGetPaymentsDashboard (proto/sirloin/v5/strip.proto:47) — the aggregated renewal, cohort and decline series behind /payments
• StripListAvailableCharacters (proto/sirloin/v5/strip.proto:49). Credits surface as fields on StripListUsers / character responses (credits_min, remaining_credits, standard_credits, full_access_credits) — no dedicated credits RPC.

The keepalive client is created in cmd/app/main.go (grpcKeepaliveTime=30s, grpcKeepaliveTimeout=10s) and reused for the process lifetime.
