# Task 1 implementation report: backend directory contract and query
|
|
|
|
## Files changed
|
|
|
|
- `myteamwallet_backend/src/users/dto/user-directory-query.dto.ts` — page, limit, and optional search input validation.
|
|
- `myteamwallet_backend/src/users/dto/user-directory-response.dto.ts` — explicit safe directory, admin, assignment, team, and reference response DTOs.
|
|
- `myteamwallet_backend/src/users/users.service.ts` — scoped directory query, search, pagination, deduplication, and explicit entity-to-DTO mapping.
|
|
- `myteamwallet_backend/src/users/users.controller.ts` — authenticated `GET /api/v1/users/directory` endpoint, declared before `:id`.
|
|
- `myteamwallet_backend/src/users/users.service.spec.ts` — focused contract coverage.
|
|
|
|
## RED test evidence
|
|
|
|
Command:
|
|
|
|
```powershell
|
|
npm test -- users/users.service.spec.ts --runInBand
|
|
```
|
|
|
|
Result: failed as expected, 7/7 tests failed with `TypeError: service.findDirectory is not a function`. This proved the missing directory-query behavior before implementation.
|
|
|
|
## GREEN verification
|
|
|
|
Commands and results:
|
|
|
|
```powershell
|
|
npm test -- users/users.service.spec.ts --runInBand
|
|
```
|
|
|
|
Passed: 1 suite, 7 tests. Covers cross-team isolation, non-admin email/secret redaction, inactive visibility, admin visibility, deduplication before pagination, search, and pagination metadata.
|
|
|
|
```powershell
|
|
.\node_modules\.bin\eslint.cmd src\users\users.service.ts src\users\users.controller.ts src\users\users.service.spec.ts src\users\dto\user-directory-query.dto.ts src\users\dto\user-directory-response.dto.ts --max-warnings=0
|
|
```
|
|
|
|
Passed with no warnings or errors.
|
|
|
|
```powershell
|
|
npm run build
|
|
```
|
|
|
|
Passed: Nest build completed successfully.
|
|
|
|
```powershell
|
|
git diff --check
|
|
```
|
|
|
|
Passed with no whitespace errors.

## Design notes
|
|
|
|
- `findDirectory(requester, query)` returns `{ data, page, limit, total, hasNextPage }`.
|
|
- A non-admin's shared-team set is derived from their active player assignments. Only users with an assignment in that set are included, and each returned assignment is filtered to that same set.
|
|
- Inactive target users and inactive assignments remain visible when their team is shared.
|
|
- Admins receive all non-deleted users and every linked player assignment. Their records extend the safe base summary with `email` and the existing `{ id, name }` role shape.
|
|
- The query maps selected DTO fields explicitly. It never serializes a `User` or `Player` entity, so passwords, hashes, social IDs, providers, and other authentication fields cannot leak through this endpoint.
|
|
- User IDs are ordered before search/pagination for deterministic pages. Users are the primary result set, which guarantees deduplication before pagination even when they have multiple player assignments.
|
|
|
|
## Self-review
|
|
|
|
- Confirmed `GET directory` is registered before `GET :id`.
|
|
- Confirmed non-admin searches only operate after visibility filtering and do not include email.
|
|
- Confirmed admin search may include email and admin mapping includes role/status using the backend's existing `{ id, name }` shapes.
|
|
- Confirmed an admin with no player assignment is included and an unassigned non-admin is not exposed to other non-admins.
|
|
- Confirmed assignment mapping includes team/team-role summary fields only, never its linked user entity.
|
|
|
|
## Concerns
|
|
|
|
- The service intentionally fetches the user and player directory sets and applies the authorization filter in memory. Task 2's planned foreign-key index work can support a future query-builder optimization without changing this safe response contract.
|
|
- The repository-wide Jest suite has documented pre-existing placeholder dependency failures in the SDD ledger; this task verified its focused suite, lint, build, and whitespace check.
