feat: filter whitespace normalization tests, creator detail include c…

[Johnsmichael150]

Summary

Four focused improvements to the creator list and feed subsystems: test coverage for filter whitespace normalization, centralized include-field constants for creator detail reads, a validated cursor decode helper for the creator feed, and a configurable slow query warning log on the creator list path.

---

Changes

1. Filter whitespace normalization tests

src/modules/creators/creators.filter.test.ts

Added unit coverage for parseCreatorFilters whitespace handling:

• leading/trailing whitespace is trimmed
• internal whitespace collapses to a single space
• whitespace-only input is dropped (no key in result)
• unknown filter keys throw with a descriptive message
• combined verified + search cases

Also aligned parseCreatorFilters to collapse internal whitespace (/\s+/g → ' '), matching the behavior of normalizeCreatorListSearchTerm.

2. Centralized creator detail include-field constants

src/constants/creator-detail-include.constants.ts
src/modules/creator/creator-profile.service.ts

Defined CREATOR_DETAIL_DEFAULT_SELECT as a single source of truth for the Prisma select fields returned on every creator detail read. Applied it in getCreatorProfile to replace the previously implicit full-row fetch. Response shape is backward compatible.

---

3. Creator feed cursor decode helper

src/utils/creator-feed-cursor.utils.ts

Added decodeCreatorFeedCursor(raw) which wraps the existing decodeCursor utility and:

• returns a discriminated union { ok: true, payload } | { ok: false, error } so callers avoid try/catch
• validates that the decoded payload contains the required createdAt and id fields
• surfaces CursorChecksumError messages directly for consistent API error responses

---

4. Slow creator list query warning log

src/config.ts
src/modules/creators/creators.utils.ts

Added CREATOR_LIST_SLOW_QUERY_THRESHOLD_MS to the env config schema (default 500ms). When fetchCreatorList exceeds the threshold, a logger.warn fires with sanitized metadata:

{
  msg: 'Slow creator list query',
  durationMs,
  thresholdMs,
  sort,
  order,
  hasSearch,        // boolean — no raw search term logged
  hasVerifiedFilter,
  limit,
  offset
}

Override the threshold via environment variable:

CREATOR_LIST_SLOW_QUERY_THRESHOLD_MS=1000

Files Changed

File	Change
src/modules/creators/creators.filter.test.ts	new — whitespace normalization tests
src/modules/creators/creators.filter.ts	fix — collapse internal whitespace in search
src/constants/creator-detail-include.constants.ts	new — CREATOR_DETAIL_DEFAULT_SELECT
src/modules/creator/creator-profile.service.ts	refactor — use CREATOR_DETAIL_DEFAULT_SELECT
src/utils/creator-feed-cursor.utils.ts	new — decodeCreatorFeedCursor helper
src/config.ts	feat — CREATOR_LIST_SLOW_QUERY_THRESHOLD_MS config key
src/modules/creators/creators.utils.ts	feat — slow query warning log

---

Testing

Run existing test suite:

pnpm test

Run filter tests directly:

node_modules/.bin/jest --testPathPatterns="creators.filter.test" --no-coverage

---

Backward Compatibility

No breaking changes. All response shapes are preserved. The new config key has a safe default.
