Phase 26 Plan 02: Discovery HTTP Routes and React Query Hooks Summary

One-liner: Three public GET endpoints at /api/discovery/{setups,items,categories} with browseTier rate limiting, wired to discovery service from plan 01, plus matching React Query hooks with typed interfaces.

What Was Built

Task 1: Discovery routes, server registration, and route tests

Created src/server/routes/discovery.ts with three Hono GET handlers following the exact pattern of global-items.ts:

• GET /setups — calls getPopularSetups(db, limit, cursor), default limit 6, max 50
• GET /items — calls getRecentGlobalItems(db, limit, cursor), default limit 8, max 50
• GET /categories — calls getTrendingCategories(db, limit), default limit 12, max 50

Updated src/server/index.ts:

• Added discoveryRoutes import
• Added browseTier rate limiting for GET /api/discovery/*
• Added auth skip: if (c.req.path.startsWith("/api/discovery") && c.req.method === "GET") return next()
• Registered app.route("/api/discovery", discoveryRoutes)

Created tests/routes/discovery.test.ts with 10 tests covering:

• Response shape validation for all three endpoints
• Empty state handling
• Limit param enforcement
• Cursor-based pagination for items endpoint
• Public-only filter for setups

Task 2: Client-side React Query hooks

Created src/client/hooks/useDiscovery.ts with three named hook exports:

• useDiscoverySetups(limit = 6) — queryKey ["discovery", "setups", limit], staleTime 2min
• useDiscoveryItems(limit = 8) — queryKey ["discovery", "items", limit], staleTime 2min
• useDiscoveryCategories(limit = 12) — queryKey ["discovery", "categories", limit], staleTime 5min

Exported interfaces: DiscoverySetup, DiscoveryCategory.

Verification

• bun test tests/routes/discovery.test.ts — 10 pass, 0 fail
• bun run build — clean build, no TypeScript errors
• Full test suite: 285 pass, 15 pre-existing failures in unrelated modules (storage.service.ts export issue in setups/items/profiles/threads routes tests)

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed cursor pagination test with simultaneous timestamps

• Found during: Task 1 test writing
• Issue: Two globalItems inserted in quick succession in PGlite got the same defaultNow() timestamp, making pagination impossible to test
• Fix: Inserted items with explicit createdAt values (2024-01-01 and 2024-06-01) to ensure distinct timestamps for pagination test
• Files modified: tests/routes/discovery.test.ts
• Commit: 0323e0c

Known Stubs

None — all endpoints return live database data from the discovery service.
