From 5a32b1791050e9ce5a77dfc5344ddab2bddb3a0b Mon Sep 17 00:00:00 2001 From: Anichris winner Date: Thu, 20 Aug 2026 11:56:18 +0000 Subject: [PATCH 1/2] feat: expose session and device management API (#131) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the session/device listing and revocation endpoints per the Phase 1 roadmap and issue #131. ## What's added ### Database - Migration 20260820120000_session_device_fields: adds deviceName, browser, os, country, city, fingerprint, lastUsedAt columns to sessions table with a composite index on (userId, isRevoked, lastUsedAt). - Prisma schema updated to match. ### API endpoints GET /api/v1/sessions — paginated list of active sessions DELETE /api/v1/sessions — revoke all other sessions (keep current) DELETE /api/v1/sessions/:sessionId — revoke a specific session All three endpoints require authenticate + requireActiveAccount. ### Security properties enforced - Cross-user access returns 404 (no session-existence leakage) - Revoking the current session returns 400 CURRENT_SESSION - No token, refreshToken, raw ipAddress, userAgent, or fingerprint fields are ever included in responses - IP addresses stored in the DB are accessible only internally; the listing endpoint exposes only device/browser/OS/country/city labels - SESSION_REVOKED and SESSION_ALL_REVOKED audit entries written atomically with the revocation ### Schemas & docs - Zod schemas for query pagination and UUID path param validation - Full @openapi annotations on all three handlers - SessionView, SessionListResponse, RevokeSessionResponse, RevokeAllSessionsResponse added to OpenAPI component schemas ### Tests (53 passing) - redactIp, redactFingerprint, toSessionView unit tests - SessionController: listing, pagination, isCurrent marker, redaction, query validation, 500 handling - SessionController: revokeOne — ok, not-found, cross-user silent 404, current-session guard, UUID validation - SessionController: revokeAll — count, plural/singular message, idempotency, 500 handling - SessionService: list, revokeOne (all result branches), revokeAll, audit logging verification Closes #131 --- .../migration.sql | 16 + prisma/schema.prisma | 12 + src/controllers/session.controller.ts | 319 +++++++ src/docs/schemas.ts | 92 ++ src/routes/index.ts | 2 + src/routes/v1/sessions.routes.ts | 41 + src/schemas/session.schema.ts | 32 + src/services/session.service.ts | 245 +++++ src/types/session.types.ts | 66 ++ tests/session.controller.test.ts | 869 ++++++++++++++++++ 10 files changed, 1694 insertions(+) create mode 100644 prisma/migrations/20260820120000_session_device_fields/migration.sql create mode 100644 src/controllers/session.controller.ts create mode 100644 src/routes/v1/sessions.routes.ts create mode 100644 src/schemas/session.schema.ts create mode 100644 src/services/session.service.ts create mode 100644 src/types/session.types.ts create mode 100644 tests/session.controller.test.ts diff --git a/prisma/migrations/20260820120000_session_device_fields/migration.sql b/prisma/migrations/20260820120000_session_device_fields/migration.sql new file mode 100644 index 0000000..1dbb69d --- /dev/null +++ b/prisma/migrations/20260820120000_session_device_fields/migration.sql @@ -0,0 +1,16 @@ +-- Add device/browser/OS/location metadata and lastUsedAt to sessions table. +-- These fields are populated from User-Agent parsing and IP geo-lookup at +-- login time and are used by the session listing endpoint. + +ALTER TABLE "sessions" + ADD COLUMN IF NOT EXISTS "deviceName" TEXT, + ADD COLUMN IF NOT EXISTS "browser" TEXT, + ADD COLUMN IF NOT EXISTS "os" TEXT, + ADD COLUMN IF NOT EXISTS "country" TEXT, + ADD COLUMN IF NOT EXISTS "city" TEXT, + ADD COLUMN IF NOT EXISTS "fingerprint" TEXT, + ADD COLUMN IF NOT EXISTS "lastUsedAt" TIMESTAMP(3); + +-- Index for efficient per-user active-session queries ordered by lastUsedAt. +CREATE INDEX IF NOT EXISTS "sessions_userId_isRevoked_lastUsedAt_idx" + ON "sessions"("userId", "isRevoked", "lastUsedAt"); diff --git a/prisma/schema.prisma b/prisma/schema.prisma index 0633f33..6fcae08 100644 --- a/prisma/schema.prisma +++ b/prisma/schema.prisma @@ -166,6 +166,17 @@ model Session { refreshToken String?
