From c0cade0a823a3a357aaa40d1e3a46dbea2867666 Mon Sep 17 00:00:00 2001 From: Andrei Date: Wed, 1 Oct 2025 21:01:23 +0000 Subject: [PATCH] Add Session Management system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements user session management with ability to view and revoke active sessions: Session Management Features: - SessionService for managing refresh tokens as sessions - List all active sessions with device information - Revoke specific session by ID - Revoke all sessions except current one - Get active session count - Session information includes device fingerprint, platform, last used, IP API Endpoints: - GET /api/v1/auth/sessions - List all user sessions - DELETE /api/v1/auth/sessions/:sessionId - Revoke specific session - DELETE /api/v1/auth/sessions - Revoke all sessions except current - GET /api/v1/auth/sessions/count - Get active session count Implementation Details: - Joins RefreshToken with DeviceRegistry for device info - Prevents revoking current session (use logout instead) - Marks sessions as current for UI indication - Orders sessions by creation date (newest first) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/modules/auth/auth.controller.ts | 50 +++++ .../src/modules/auth/auth.module.ts | 5 +- .../src/modules/auth/session.service.ts | 189 ++++++++++++++++++ 3 files changed, 242 insertions(+), 2 deletions(-) create mode 100644 maternal-app/maternal-app-backend/src/modules/auth/session.service.ts diff --git a/maternal-app/maternal-app-backend/src/modules/auth/auth.controller.ts b/maternal-app/maternal-app-backend/src/modules/auth/auth.controller.ts index 2549072..47c1b1e 100644 --- a/maternal-app/maternal-app-backend/src/modules/auth/auth.controller.ts +++ b/maternal-app/maternal-app-backend/src/modules/auth/auth.controller.ts @@ -11,10 +11,13 @@ import { ValidationPipe, Ip, Headers, + Param, + Req, } from '@nestjs/common';
